filip131311	11f384d37f	fix(chromium): make Electron apps testable without window focus (#605 ) ## Problem Field report: "electron needs focus to be tested." Analysis confirmed three focus/visibility dependencies in the Chromium/Electron surface: 1. Hidden window → throttled renderer. A minimized/occluded window's compositor throttles: mouse-input acks stall ~5 s per event (they wait on hit-testing), wheel scrolls hang (`gesture-scroll` already refused), `visibilityState` flips to `hidden`. 2. Unfocused window → focus-gated app logic breaks. `document.hasFocus()` is `false` before any input arrives; focus/blur-dependent UI misbehaves. 3. Focus-gated web APIs (clipboard already worked around it locally with `Page.bringToFront`). ## Fixes 1. CDP focus emulation on every page session (`primePageSession`, né `enableCoreDomains`): `Emulation.setFocusEmulationEnabled(true)`, best-effort, re-applied automatically after tab switches (Playwright precedent). Live A/B on the Electron testbed: identical boot→unfocus→probe sequence gives `hasFocus:false` on main, `true` on this branch. Bonus verified by A/B (kill server → same minimized window flips to `hidden`): in current Chromium/Electron, emulation also pins reported visibility to `visible` and keeps input unthrottled while genuinely minimized — minimized tap latency ~5 s → ~65 ms, wheel scroll works. Trade-off (same as Playwright ships): while attached, the app can observe neither real blur nor real hidden, so pause-on-hidden behavior is unobservable during a test. 2. Anti-throttling switches for every argent-booted Electron app (`--disable-background-timer-throttling --disable-backgrounding-occluded-windows --disable-renderer-backgrounding`). Sessions are created lazily and die with the idle-exiting tool-server while the app outlives it — the flags cover that detached lifecycle plus emulation-less runtimes. Also covers flow-booted apps via the shared `bootElectronApp`. 3. Hidden-window fail-fast extended from gesture-scroll to gesture-tap + gesture-drag via shared `assertChromiumWindowVisible`, under a new dedicated `CHROMIUM_WINDOW_HIDDEN` failure code (scroll migrated; `failure_stage` strings unchanged so telemetry stays joinable — analytics keyed on `CHROMIUM_INPUT_INVALID` + `chromium_scroll_window_hidden` should switch to the new code). With emulation active the guard is a backstop that fires only where emulation couldn't be applied — exactly where the stall is real. Keyboard/button stay unguarded on purpose: measured live, key events skip hit-testing and stay fast on hidden windows. ## Verification - Unit: 3075 tool-server + 87 registry tests green, `typecheck:tests` green, new tests for emulation priming, boot args, and the guard (all three tools). - Live matrix on the Electron testbed (dev tool-server): focused baseline; unfocused (`hasFocus` true pre-input, typing lands); minimized booted app (tap 69 ms, scroll works, typing + slider drag land, screenshot fine); minimized external un-flagged app on :9222 (tap 63 ms, scroll 460 ms — emulation alone suffices while attached). - Plan + implementation went through three adversarial review rounds (scope, CDP semantics, failure-code taxonomy/telemetry compat, doc accuracy). 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-07-31 15:36:36 +02:00
filip131311	05f53502ab	feat(tool-server): drive iOS simulators from additional CoreSimulator device sets (#600 ) > Recreates #543 — GitHub auto-closed it when the base branch of the stacked PR (#542) was deleted on merge, and a closed PR cannot be reopened after its head is force-pushed. Same commit, rebased onto main. ## Summary Was stacked on #542 (now merged). Consumes the `ios.additionalDeviceSets` configuration across the iOS tool surface, so simulators living in extra CoreSimulator device sets — e.g. Radon IDE's `~/Library/Caches/com.swmansion.radon-ide/Devices/iOS` — are discovered by `list-devices` and drivable by every tool, by UDID, exactly like default-set devices. ### The core piece: a UDID → device-set map (`utils/ios-device-sets.ts`) simctl scopes every operation to one device set, so each per-device call must know the target's owning set. The new module owns that mapping and the single argv choke point: - Learned from discovery: `list-devices` and the simulator watcher enumerate the default set + every configured set and `rememberDeviceSet` each sighting — any tool used after a list hits a warm cache. - Lazy fallback: an unknown UDID triggers one `simctl list` probe per configured set, cached on hit. An unknown-everywhere UDID resolves to the default set without caching (a device that appears later is found on the next call) — preserving pre-feature behavior and error messages byte-for-byte. - `simctlArgsForUdid(udid, args)` builds the full argv (`--set` injected only for additional-set devices); `simctlPrefix` covers multi-call sites that resolve once; sync variants (`simctlArgsForUdidSync`, `cachedDeviceSetForUdid`) cover the `ChildProcess`-returning and `execFileSync` call sites, each of which runs after an async step that warmed the cache. - Config is read off disk per call (the #534 design): editing `ios.additionalDeviceSets` applies without a tool-server restart. - Guard: a configured set whose directory doesn't exist is never queried — simctl would materialize the dir, turning a config typo into a stray directory. ### Wired consumers - `list-devices` — enumerates every set, tags additional-set devices with `deviceSet`, documents the field. - `simulator-watcher` — polls every set (a set failing to list throws → the tick is skipped, so a transient error still can't mass-dispose tracked services); warms the map for the injection path. - simulator-server blueprint — passes `--device-set` (the same flag Radon IDE passes to this shared binary); default-set spawns unchanged. - `ax-prefs` — the pre-boot AX plist now lands under the owning set's device dir (previously hardcoded to the default `CoreSimulator/Devices` root, so the write would land nowhere for these devices and describe would degrade). - `boot-device` — set-aware shutdown/boot/bootstatus; skips the Simulator.app attach + `CurrentDeviceUDID` write for additional-set devices (one Simulator.app instance displays one device set — these run headless and are streamed, exactly how Radon IDE presents them). - Every remaining per-device simctl call site: launch-app / restart-app / reinstall-app (both the direct impls and the `SimctlBackend` shared handlers), open-url, settings-permissions (privacy + install probe), the tvOS screenshot fallback, status-bar pin/restore, device-shutdown, the ios-host `simctl spawn` family behind describe/native-devtools, tv-control's AX daemon, and the native profiler's sync helpers (cache warmed at `startNativeProfilerIos`). Out of scope: `sim-remote` — the remote orchestrator host has its own device-set story. ## Testing - Unit: new `ios-device-sets.test.ts` (mapping, lazy probe + caching semantics, no-probe fast path with no sets configured, discovery enumeration/tagging/dedup, missing-dir guard); blueprint test asserts the `--device-set` argv; the profiler shell-injection mock extended for the new import. Full tool-server suite green: 276 files / 2752 tests; `tsc --build`, eslint, prettier clean. - Live, end-to-end on a real Radon IDE device (iPhone Air, iOS 26.4, in `com.swmansion.radon-ide/Devices/iOS`), driving this branch's tool-server over HTTP with the config set at project scope: - `list-devices` → the Radon device appears, tagged with its `deviceSet` (invisible to argent 0.16.1 on the same machine); - `boot-device` → boots headless in its set, no Simulator.app window; - `screenshot` → real home-screen PNG via simulator-server spawned with `--device-set`; - `launch-app` (Settings) → launched via `simctl --set launch`; - `describe` → full accessibility tree from the Settings screen, i.e. the AX bootstrap (set-aware prefs + in-sim ax-service daemon via `simctl --set spawn`) works; - clean shutdown; default-set devices meanwhile listed and behaved exactly as before.	2026-07-31 15:14:03 +02:00

Ignacy Łątka	7e4ece697d	chore: add server.json for the official MCP registry (#598 ) Adds the two files the official MCP registry (`registry.modelcontextprotocol.io`) needs in order to list argent. Argent is not in that registry today (`?search=io.github.software-mansion` returns 0 servers). The registry is metadata-only — it points at the npm package rather than hosting anything. ### `server.json` Describes the server and how a client starts it: `npx @swmansion/argent mcp`. The `mcp` positional is the dispatcher case in `packages/argent/src/cli.ts:137`, and it is the same subcommand `argent init` writes into every client config — `packages/argent-installer/src/mcp-configs.ts:130-141` spells it four ways (`node <path> mcp`, `yarn argent mcp`, `npx --no-install argent mcp`, and the global `{ command: MCP_BINARY_NAME, args: ["mcp"] }`, where `MCP_BINARY_NAME` is `"argent"`). None of them is literally the npx-by-package-name form in `server.json`, which is the form the registry expects a client to construct from `identifier` + `runtimeHint` — so it is verified below by running it, not by matching a string. `repository.id` is the GitHub repo id (`1164885639`); the schema recommends it so a registry can detect a delete-and-recreate of the repo. ### `mcpName` in `packages/argent/package.json` The ownership proof. The registry fetches the npm package and requires `mcpName` to equal the server name in `server.json` before it will accept a publish under `io.github.software-mansion`. It is the field the registry's own quickstart names for npm packages. Nothing in the publish path drops it: `scripts/pack-mcp.cjs` shells out to `npm pack` without rewriting the manifest, and the canary path's `scripts/next-canary-version.mjs --write` round-trips the JSON and only sets `version`. ### Namespace `io.github.software-mansion/argent` — GitHub OAuth auth. The registry grants an org namespace only to org Owners; plain membership is no longer enough. If no Owner is available to run the publish, the alternative is DNS auth via an apex TXT record on `swmansion.com`, which changes the name to `com.swmansion/argent` (and the `mcpName` value with it). ### Version sync `server.json` sits at the repo root, outside `packages/`, so a release bump would have left its two `0.18.0`s untouched — and the registry rejects a publish whose `packages[].version` names a version npm has never seen. `scripts/check-workspace-versions.mjs` (already run by the Static checks job) also holds `server.json` to the version in `packages/argent/package.json` — the package it names — and pins the two cross-file links a publish depends on: `name` == `mcpName`, `identifier` == the published package name. Both halves are reported in one run, so a half-finished bump doesn't cost a CI round-trip per file. ### Not in this PR - Publishing.* Nothing has been published; this is just the manifest. Publishing is `mcp-publisher login github && mcp-publisher publish`, and it can only succeed after a release whose npm tarball carries `mcpName` — i.e. not against `0.18.0`, which is `latest` (published 2026-07-30) and predates `mcpName` — `curl registry.npmjs.org/@swmansion%2Fargent/0.18.0 \| jq .mcpName` → `null`. The first publishable release is the next bump. - `github.com/mcp`. A separate, manual step. Onboarding a new server there is hand-curated: per [github/github-mcp-server#1257](https://github.com/github/github-mcp-server/discussions/1257) (trent-j, a collaborator on that repo, 19 May 2026) "onboarding a new server is still a manual curation process today. Once a server has been onboarded, newly published versions from the OSS registry should sync from there." The nomination channel is `partnerships@github.com`, from GitHub's [registry how-to post](https://github.blog/ai-and-ml/generative-ai/how-to-find-install-and-manage-mcp-servers-with-the-github-mcp-registry/) (24 Oct 2025) — that address does not appear anywhere in the discussion thread. ### Verification - `mcp-publisher validate` (v1.8.0, which posts the file to the live registry) → `server.json is valid`. Mutation-checked what that actually covers: removing `transport` fails it and removing `$schema` is a 422, but a foreign namespace (`io.github.anthropics/argent`), a nonexistent npm identifier and a `99.0.0` package version all still pass — so it checks shape only, and the ownership/existence checks happen at publish time. Also validated offline against the pinned `2025-12-11` schema. - Ran the entrypoint the file declares. `npx -y @swmansion/argent@latest mcp` fed an `initialize` over stdio answered `{"protocolVersion":"2024-11-05","capabilities":{"tools":{}},"serverInfo":{"name":"argent","version":"0.18.0"},"instructions":"…"}`, with stderr empty. - Mutation-checked the new version guard: drifting `server.json` `version`, drifting `packages[0].version`, deleting `mcpName`, and typo-ing `identifier` each fail `check-workspace-versions.mjs` with the specific line; the pre-existing packages/* drift check still fires on its own. - Asserted across the two files: `mcpName` == `server.json` `name`, `identifier` == package `name`, all three versions equal, description 89 chars (registry limit is 100). - `prettier --check` and `eslint` clean on both changed files. - Mutation-checked the guard as a whole — 22 mutants, 1 survivor. Killed: reverting the self-invocation guard to a raw `argv[1]` compare and making it never match; `exit(1)` → `exit(0)` on the failure path; dropping either `failed = true`; exiting early on `packages/` drift instead of collecting; `packages.slice(0, 1)`; hardcoding `packages[0]` in either message; dropping the no-packages-array guard, the non-object-entry guard, the non-object-JSON guard, and the presence checks for `version`, `name` and `mcpName`; `continue` → `break` in the `packages/` scan (both arms) and in the entry loop; dropping the on-message read, the `git checkout` hint, and the per-version name accumulator. The survivor is the `packages/` readdir sort: it fixes the scan order rather than any output, so no single run can observe it — it is there so a scan that stops early drops the same packages on every machine instead of a filesystem-dependent set. - Reproduced the symlink no-op on the real repo: with `packages/registry` at `9.9.9` and `server.json` at `0.17.0`, `node /tmp/argent-alias/scripts/check-workspace-versions.mjs` now exits 1 and prints both problems, where before it exited 0 with no output at all. - Closed the vacuous-pass class in `serverJsonMismatches`: all four comparisons it makes were bare `!==`, so a field absent from both* sides compared equal and passed. A `packages/argent/package.json` with no `version` printed `All workspace packages and server.json are at undefined.` and exited 0; with no `name`, a `server.json` naming nothing installable was reported in sync. `version` and `name` now require presence, as `mcpName` already did. - `readTrackedJson` guarantees an object, not just parseable bytes — a `server.json` holding `null` used to reach the field reads and throw, and `"0.18.0"` or `[]` produced mismatch lines that never said the file was the wrong shape. - Full CI parity locally: `test:scripts` 85/85, `tsc -p tsconfig.scripts.json`, `eslint --max-warnings 0`, `prettier --check`.	2026-07-31 12:36:44 +02:00
filip131311	fc09612f30	feat(config): `recordings.directory` — configurable save location for screen recordings (#601 ) ## Summary Adds a `recordings.directory` configuration entry (built on the #534 config system) that lets users choose where finished screen recordings (mp4) are saved, instead of the fixed `<project>/.argent/recordings/`. - Schema entry (`configuration-core`): scopes `project` + `global`, `prioritize-local` merge (project wins when both are set). Picked up automatically by `argent config set/get/unset/list`. - Value semantics: absolute path, `~`-prefixed (expands to home), or relative — relative anchors at the project root (home dir when not in a project). - Client-side wiring (`argent-tools-client` `durableSaveTarget`): the wire `saveDir` hint stays `.argent/recordings` (wire contract unchanged → old/new client-server interop). Past the existing client allowlist, the recordings hint is remapped to the configured directory. ## Security model unchanged The allowlist exists because `saveDir` arrives from a possibly-hostile remote tool-server. That gate still runs first and is unchanged: a server can only select the sanctioned recordings category, never name a destination. The configured directory comes from the client's own trusted config files. Exclusive never-overwrite writes (`name (2).mp4`), the durable download size caps, and the symlink real-path guard all remain; for a configured dir the realpath check degenerates to "the dir resolves to itself" (a user-chosen symlink is legitimate, matching how the default base may be symlinked). A test asserts hostile wire values (`.git`, `..`, absolute) stay rejected even with config set. ## `argent link` interaction Materialization always runs on the client (co-located → copy from `hostPath`; remote → download over `/artifacts/:id`), and the config is read there at materialize time — so with a remote tool-server the mp4 lands on the client host per the client's config, on both paths. ## Testing - New unit tests: 10 in `argent-tools-client` (absolute/`~`/relative resolution, local-vs-global precedence, both materialization paths, hostile wire values with config set) + 4 in `configuration-core` (scope writes, trim, precedence, validation). - Suites green: tools-client 188, configuration-core 87, tool-server screen-recording 62, CLI config 16; full workspace vitest 4727 pass (3 pre-existing `scripts/.test.mjs` node:test files don't parse under root vitest — unrelated). - Live E2E* on an iPhone 15 Pro simulator via the branch tool-server: real recording captured, then materialized through the branch client with configs written by the real `argent config` CLI in a sandboxed HOME/project. 7 scenarios green: default location, global-only (`~` path), project-only (relative), both-set → project wins (co-located and remote download with Bearer auth), unset fallbacks, `argent config list` rendering. Remote-downloaded mp4 ffprobe-verified (byte-exact size, 4.17 s duration); name-collision suffixing observed live. 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-07-31 12:36:31 +02:00
filip131311	cccda92d15	feat(config): `ios.additionalDeviceSets` — additive array of extra CoreSimulator device sets (#542 ) ## Summary Stacked on #534. Adds the first additive configuration entry on the new schema — `ios.additionalDeviceSets`, a list of extra CoreSimulator device-set directories — delivering the config side of the #401 discussion on the #534 machinery. ### The schema entry One registry entry in `config-schema.ts`: - key `ios.additionalDeviceSets`, scopes `project` + `global`, `parse: asStringArray`, `merge: "union"` Unlike `lens.agent` (project shadows global), this is additive: the effective value is the union of both scopes — the global baseline first, the project's extras appended, deduplicated. A repo can commit the device sets its tooling needs to `.argent/config.json` and they extend (never replace) the user's global list. `argent config list/get/set/unset` handle the array key with zero command changes — arrays already round-trip through the JSON value coercion. ### The runtime reader `getAdditionalIosDeviceSets(options): string[]` in `config-access.ts` — the surface iOS tooling should call. It reads each scope separately so paths normalize against the base the author meant: - `~` / `~/…` expands to the home directory (honoring the sandbox `homeDir` override) - relative project entries resolve against the project root, relative global entries against home - output order matches the `union` preset (global first), with post-normalization duplicates dropped — `~/DeviceSets/ci` in global and its absolute spelling in the project file collapse to one entry - empty array when unset Support refactor: `resolveHomeDir()` extracted in `paths.ts` (the HOME/USERPROFILE + override logic previously inlined in `argentHomeDir`/`configDir`). ### Out of scope (follow-up) Actually pointing simctl at the extra sets. There is no central simctl wrapper today (~25 call sites build `xcrun simctl …` argv inline, and `ax-prefs.ts` hardcodes the default set's `CoreSimulator/Devices` path), so consuming this reader in `list-devices`/boot/etc. is its own change — the runtime-read-off-disk design here means that consumer needs no CLI/env threading, matching how #534's description framed the split. ## Testing - `configuration-core`: 5 new tests (82 total, green) — additive union across scopes + per-scope file isolation, non-array rejection + entry normalization, reader `~`/relative resolution per scope, post-normalization dedup, empty-when-unset - `argent-cli`: new real-filesystem CLI round-trip (274 total, green) — `config set` an array at each scope, effective `get` shows the union while `get --scope` shows only that scope's entries - `tsc` build + `typecheck:tests` + eslint clean on touched packages	2026-07-31 10:27:25 +02:00

Hubert Gancarczyk	5ac69349f0	feat(flow): CSS combinator scopes for flow selectors (#569 ) ## What Adds the CSS combinators to flow selectors, read off frames. Any action or condition can now scope its matches by where an element sits relative to another: ```yaml - tap: { text: Delete, within: { id: profile-card } } # CSS "A B" — inside that container - tap: { role: Switch, next: { text: Wi-Fi } } # CSS "A + B" — the nearest follower - assert: { visible: { role: Button, after: { text: Danger zone } } } # CSS "A ~ B" — any follower - assert: { hidden: { any: true, within: { id: empty-state } } } # CSS "" — the universal selector ``` \| Scope \| CSS \| Reads as \| \| --- \| --- \| --- \| \| `within: <sel>` \| `A B` \| the match's frame sits inside the scope element's frame \| \| `after: <sel>` \| `A ~ B` \| the match follows the scope element in reading order \| \| `next: <sel>` \| `A + B` \| as `after`, narrowed to the nearest follower of each anchor \| Plus `any: true` — the CSS `` universal selector, accepted only alongside a scope and never beside `text`/`id`/`role`. The child combinator `>` has deliberately no analog: flow trees flatten to leaves under one synthetic root, so parent/child structure does not survive to replay. ## How - Geometric, not ancestry-based. Frames are what survives flattening, so every scope is resolved from them by `findAll` in `ui-tree-match`. The synthetic root never counts as a scope element, and every relation requires a distinct node (nothing scopes itself). - Reading order is row-band aware. An element follows the anchor when it starts below the anchor's bottom edge, or shares its row band and sits entirely to its right. That band rule is what makes `{ role: Switch, next: { text: Wi-Fi } }` resolve the Wi-Fi row's own switch even though the taller switch's frame starts a couple of pixels higher than the label's — a raw top-y comparison gets that backwards. `followKind` is the single classification both the follower test and the nearest-pick grouping read, so they cannot disagree. - `next` is the union over anchors, exactly as CSS `A + B` is: three rows on screen give three switches, one per label. - Scopes compose and nest, capped at `MAX_SELECTOR_SCOPES` (6) counted across the whole relation tree — a size bound, not a depth bound, because three relations branch and the runner's loose-alternative expansion is exponential in the bare-string scopes it finds. - Flow-YAML only. `await-ui-element`'s strict schema rejects `within`/`after`/`next`/`any`, so a scope can never be silently dropped on that path. - Adding a fourth relation is a compile error: `RELATION_RESOLVERS` is a `Record` keyed by the relation union, so a new scope cannot be wired through parse/serialize/reporting and then ignored by the match engine. ## Testing - Unit: full tool-server suite green — 3006 passed / 1 skipped. New coverage in `ui-tree-match.test.ts`, `flow-utils.test.ts`, `flow-selector-scopes.test.ts` (renamed from `flow-within-selector.test.ts`, now covering all scopes) and a new `flow-skill-docs.test.ts` that parses every YAML snippet in the skill so the docs cannot rot. Each fix is mutation-checked: reverting it fails at least one test. - Real-device E2E (Pixel 3a, Bluesky on Metro 8081, via a branch tool-server): three flows, 20 steps, all green — geometric ordering both ways, two `text` asserts that pin `next`'s pick by identity out of five candidates, empty-scope `hidden` semantics, and two observable taps (`next`-scoped and `any: true`-scoped) that navigated to the adjacent topic rather than the anchor's own. - iOS not covered. Native-devtools does not attach on either booted simulator in this environment, so every flow selector fails there — an unscoped `{ text: "Video" }` fails identically. Verified environmental, not caused by this branch: the globally-installed argent reports the same, direct `SIMCTL_CHILD_DYLD_INSERT_LIBRARIES` injection also fails to connect, and it survives a forced simulator reboot on both iOS 18.3 and 26.5. Worth re-running the iOS leg once that is healthy. ## Notes for reviewers Two deliberate deviations from CSS, both documented in the skill: - `next` is looser than `+`. Where `A + B` matches nothing unless the immediate sibling is a `B`, `next` keeps looking and returns the nearest match further on. That is what makes it survive the wrapper and spacer nodes a flattened tree is full of — but a row missing the control you asked for resolves to the next row's rather than failing. Happy to switch to strict `+` semantics if the loud failure is preferred. - "follows" is not transitive. Against a tall anchor an element can follow something that follows the anchor without following it directly, so nesting `after` scopes is not the same as chaining `~`. Other things worth a look: - `nearestAfter` and `afterTester` are direct scans, not indexed. An earlier sorted index was a second implementation of the nearest rule and the two disagreed on frames near the tolerance; it also measured 2-13x slower than the scan on realistic shapes, with a prune that provably never fired. The quadratic tail is documented with measured numbers: 1.2 ms for a single-anchor `next` at the 12k-node tree cap, ~555 ms only when the anchor selector matches essentially every node. - A bare-string anchor cannot self-correct the way the loose fallback usually does — a decoy `testID` matching your anchor text wins the identifier pass whenever anything sits after it. The skill tells authors to spell sibling anchors as maps. - `MAX_SELECTOR_SCOPES = 6` replaces the previous `MAX_SELECTOR_WITHIN_DEPTH = 10`, so a `within` chain deeper than 6 that parsed on the earlier commits of this branch now rejects. Nothing released depends on it. --------- Co-authored-by: Hubert Gancarczyk <claude-hubert.gancarczyk@swmansion.com>	2026-07-27 18:25:27 +02:00
Jakub Piasecki	e23f0e285e	feat(flow): snapshot cropOn for single-element visual diffs (#516 ) `snapshot` gains an optional `cropOn: <selector>` — diff one element's region instead of the whole screen: `- snapshot: { name: cart-total, cropOn: "Order summary" }` - The selector resolves like a directive target: settled tree, auto-wait, the standard not-found failure. Selector-only — no point form (a point has no extent to crop to). - The frame resolves before the capture, and the cropped image is what gets compared, stored as the baseline, and reported as the `current` artifact. The pixel rect is the normalized frame × capture size; the crop is a pngjs `bitblt` written to a swept scratch dir and registered only when a failure returns it. - The baseline key stays on the full capture's WxH (device-class identity), so the previously unreachable `dimensionMismatch` guard becomes load-bearing: an element that grew or shrank fails with "nothing was compared" plus a crop-fixed-size-containers hint. Deliberately strict — a 1px layout drift fails on dimensions, not content (the same tradeoff as Playwright element screenshots). - A tree-source outage while resolving `cropOn` errors the step instead of degrading to a full-screen compare against a cropped baseline. - No tool-schema changes; `snapshotKey` and `--output` behavior ride along unchanged. Tests: parse/serialize round-trip + rejection cases, and runSnapshot coverage with real PNGs (crop dims, key vs. content, artifact retention/sweep, unresolved selector, abort, size-drift message, sub-pixel region).	2026-07-27 10:07:49 +02:00
filip131311	68ceb314d6	ci: cut over npm publishing to the unified trusted-publishing workflow (#571 ) ## Why Cutover step 3+4 of the plan from #565. `publish-npm.yml` is now registered on npmjs.com as the trusted publisher for `@swmansion/argent` (2026-07-24) and the OIDC publish path is verified live: `v0.17.1-next.1` published with a SLSA provenance attestation via a workflow_dispatch of the unified workflow. Extra urgency: token-based publishing died on 2026-07-24 (~11:20–15:20 UTC window; npm's 2FA-bypass token restriction) — `publish-next.yml`'s canary now fails on every main push (identical E404 on the registry PUT, e.g. run 30104847558). The old workflows aren't just redundant, they're broken; only the trusted-publisher workflow can publish. ## What - Delete `publish.yml` and `publish-next.yml` — `publish-npm.yml` is the only publish path. - `sync-next-tag.yml`: drop the two retired workflow names from the `workflow_run` trigger. - `publish-npm.yml`: remove `NODE_AUTH_TOKEN` from both publish steps (OIDC authenticates; the rest of the job already ran token-less) and update the header — the cutover plan is replaced by a note that this file's name is load-bearing for the npmjs.com registration. - `NPM_TOKEN` stays as a secret: `sync-next-tag.yml` still needs it for dist-tag mutation, which OIDC doesn't cover. Note the token may currently be dead for dist-tag writes too — the post-publish sync run succeeded but had no mutation to make; if a real re-point fails, a fresh granular token is needed. ## After merging Set the repo variable to enable canary-on-push (kept as the canary kill-switch): ``` gh variable set PUBLISH_NPM_UNIFIED --repo software-mansion/argent --body "1" ``` Ordering is safe: until the variable is set, a main push publishes nothing (the old canary workflow is gone, the new one skips) — no double-publish window exists. 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-07-24 17:54:00 +02:00
filip131311	2546788a8d	ci: unified publish-npm workflow (provenance-ready, trusted-publishing prerequisite) (#565 ) ## Why npm provenance / trusted publishing for `@swmansion/argent` requires registering one workflow file as the package's trusted publisher on npmjs.com — but we currently publish from two (`publish.yml` for stable, `publish-next.yml` for canaries/prereleases). This PR adds their unified successor, `publish-npm.yml`, without touching the old workflows: they keep running unchanged until cutover. ## Design One file, mode derived from the trigger and the version — nothing is spelled twice: \| Trigger \| Behavior \| \|---\|---\| \| `push` to `main` \| Canary: version derived + stamped (`<base>-next.<k>`), published under `next` with the same registry-race retry loop as before. Dormant until the `PUBLISH_NPM_UNIFIED` repo variable is set to `1` — otherwise every main push would publish two canaries while `publish-next.yml` still exists. \| \| `workflow_dispatch` \| Publishes the ref's `package.json` version verbatim. Dist-tag derived from the version itself: prerelease → `next`, stable → `latest`. The optional `channel` input is an assertion (fails on mismatch), not a selector — you can't accidentally ship a prerelease to `latest` or vice versa. `dry_run` runs the full build + bundle verification + pack without publishing. \| Provenance is on from day one: the job has `id-token: write` and every publish path uses `--provenance` (repo is public, `repository.url` matches — the two things the registry verifies). Token auth (`NPM_TOKEN`) is kept for now; npm ≥ 11.5.1 is ensured in the job so the OIDC exchange takes over transparently once the trusted publisher is registered. `sync-next-tag.yml` now also triggers on the new workflow, so `next` keeps getting re-pointed after publishes from either generation. (Until cutover a main push may trigger the sync twice — once per publish workflow — which is harmless: the script is idempotent.) ## Cutover checklist (follow-up, also documented in the workflow header) 1. Test: `workflow_dispatch` with `dry_run`, then a real prerelease dispatch (`v*-next.N` ref). 2. On npmjs.com, register `publish-npm.yml` as the trusted publisher for `@swmansion/argent` (org `software-mansion`, repo `argent`). 3. Set repo variable `PUBLISH_NPM_UNIFIED=1` and delete `publish.yml` + `publish-next.yml` in the same PR (also dropping their names from `sync-next-tag.yml`'s `workflow_run` trigger). 4. Remove `NODE_AUTH_TOKEN` from the publish steps (`NPM_TOKEN` stays for `sync-next-tag.yml` — dist-tag mutation isn't covered by OIDC); optionally restrict the package's publishing access to the trusted publisher only. ## Behavior differences vs the old pair - Stable dispatch now publishes with an explicit `--tag latest` (same effect as the old default) and `--provenance`. - The old `publish-next.yml` dispatch guard ("refuse non-prerelease versions") is generalized: a stable-version ref dispatched here goes to `latest` instead of erroring. Set `channel: next` if you want the old refusal behavior. 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-07-24 17:20:18 +02:00
Jakub Piasecki	6a53e66a96	feat(flow): rotate directive (#546 ) # feat(flow): rotate directive Adds a selector-targeted two-finger rotation directive to flows: `rotate: { on?, by }`. `on` resolves like `tap` (settled tree + auto-wait); omitted, the rotation centers on the screen. `by` is degrees, positive = clockwise. Distinct from `tool: rotate`, which changes device orientation — the docs and step labels call this out. ## Design One continuous gesture, fixed pace, no duration option. Fingers orbit at ~90°/300 ms; duration derives from the angle. Unlike pinch there is no sub-gesture chaining — any angle dispatches as one sweep, so the angular delta is exact with no settle delays. `by` is parse-bounded to ±3000°: the largest sweep the 10 s single-gesture envelope delivers at that pace, derived from the constants rather than picked as policy — rejected at parse, never silently clamped. A consequence embraced here: frame count always scales with the angle, so a speed-sensitive recording stays a raw `tool:` step (the create-flow skill's polish list covers the conversion). Fixed centroid, constant physical radius. Drifting the centroid would couple pan into the turn; growing the radius would couple pinch. Both stay fixed — the trade is a smaller orbit near edges and small targets, in exchange for a pure rotation. Physical circle, not a normalized-space ellipse. A single normalized radius on a non-square screen traces a physical ellipse, coupling an unintended pinch into every turn. `gesture-rotate` grows optional per-axis `radiusX`/`radiusY` (fractions of width/height with `radiusX·W = radiusY·H`), and the flow tree adapters surface screen dimensions via an optional `screen` field on `DescribeTreeData` so the directive can compute the aspect. Missing dimensions fail soft to the legacy single-radius call rather than erroring. Placement reuses pinch's edge model. The initial finger axis (horizontal or vertical) is scored against the same per-platform system-edge guards, preferring a start parallel to the nearest violated edge and staying inside the target's axis-matching span. Guards only score placement — they never shrink the radius, and a violated guard is attempted, never rejected. The only geometry failure is no positive on-screen orbit radius. Abort correctness. `gesture-rotate` now honors `ctx.signal`: each frame checks it, lifts the synthetic fingers with a terminal Up (so a cancelled run doesn't leave them held on the glass), then throws with name `AbortError`; the directive maps a mid-gesture abort to the run's aborted skip rather than a step failure. Explicit `inputSchema`. The radius requirement is a zod `.refine()` cross-field rule, which `z.toJSONSchema` drops — so the tool ships a derived schema plus an explicit `anyOf` (`radius` or `radiusX`+`radiusY`) to keep invalid calls rejected at the schema layer. Platform rejections. Vega is remote-driven (no touch) and Chromium has no rotate-gesture idiom at all — both fail upfront with guidance to drive the app's rotate controls directly. ## Tests Unit tests cover the geometry module (duration derivation, candidate construction, aspect handling, edge-guard ranking), the directive end-to-end against a fake device, and `gesture-rotate`'s per-axis radii and abort path.	2026-07-24 13:18:23 +02:00
Ignacy Łątka	a0460eeefe	chore: bump workspace packages to 0.17.0 (#554 ) ## What Lockstep-bump all 16 `packages/` workspace packages (and the matching `package-lock.json` entries) from `0.16.1` → 0.17.0. Diff is exactly 32 version-field swaps across 17 files — no formatting or dependency churn. ## Verification - Lockfile CI gate reproduced locally on the exact CI toolchain* (Node 24.14.1 / npm 11.11.0, matching `lockfile.yml`'s `node-version: "24"`): `npm install --package-lock-only --ignore-scripts` on top of the commit, then `git diff --exit-code -- package-lock.json` → clean. npm's own regeneration reproduced the hand-edit byte-for-byte, so none of the `"peer": true` churn that #513/#539 had to keep out reappears here. - `node scripts/check-workspace-versions.mjs` → `All workspace packages are at 0.17.0.` - Remaining `repo-hygiene.yml` checks pass: no conflict markers, no focused tests. - `prettier --check` on all 17 changed files → `All matched files use Prettier code style!` - Runtime version actually reports 0.17.0: `getInstalledVersion()` (`argent-installer/src/utils.ts:384`) and `getGloballyInstalledVersion()` (`topology.ts:94`) both read `version` straight out of the resolved package root's `package.json` at runtime, so the bump is the whole mechanism — no generated constant or second version file to keep in sync. Exercised that resolution against the bumped tree: `PACKAGE_ROOT` → `packages/argent` (`@swmansion/argent`) → `0.17.0`. - Verified all 16 lockfile hits belong to workspace packages (parsed the lockfile's `packages{}` and matched every `0.16.1` entry to a `packages/` path) — no unrelated dependency happened to sit at 0.16.1. - No test asserts a release version string; the only `0.1x.x` matches under `.test.ts` are historical references inside comments. ## Note `packages/argent-private` needs no pin change here. Its release version is carried purely as a git tag — the repo has no version field on the release line (its only `package.json` is a `private: true` research CLI on an independent `0.1.0` line) — and `v0.17.0` is now tagged at `2d6c292`, which is already the commit this superproject pins. `v0.16.0` and `v0.16.1` sit on that same commit, so the submodule entry is correct as-is and stays out of this diff. v0.17.0	2026-07-23 23:33:49 +02:00
Ignacy Łątka	98ae93145b	feat(screen-recording): save recordings to the project's .argent/recordings (#551 ) Stacked on #549 (touch visualizer). ## What Screen recordings now land durably under `.argent/recordings/` on the client, instead of the disposable temp-artifact cache — and for a remote `argent link` tool-server they land on the client host, not the server. ## Why Two rough edges in the recording flow: 1. The finished video was only ever written to the OS temp-artifact cache, so it was easy to lose and not obviously part of the project. 2. Over `argent link`, the video was downloaded into that same temp cache; there was no project-scoped home for it. ## How - New optional `saveDir` hint on the artifact wire contract (`@argent/registry` + `@argent/tools-client`). - `screen-recording-stop` tags its video with `saveDir: ".argent/recordings"` and drops the internal `argent-` temp prefix from the filename. - The client materializer honours `saveDir`: copies the file when the tool-server is co-located, downloads it over `/artifacts/:id` when it is remote. Either way the bytes end up in the durable directory. - `saveDir` resolves against the client's project root (nearest ancestor with `.git`/`package.json`/`.argent`), falling back to the global `~/.argent` when run outside a project — matching how the rest of argent scopes per-project config. Adds `findProjectRoot` to `configuration-core` (a null-returning variant of `resolveProjectRoot`) to drive that choice. - Hardened: absolute paths and `..` escapes are rejected, directory bundles excluded — a tool-server can't steer a write outside the base directory. ## Verification - Unit: 28 cases in `argent-tools-client/test/artifacts.test.ts` (co-located copy, remote download, project-root anchoring incl. from a subdirectory, global fallback, path-traversal rejection, integrity). configuration-core suite green (55). - E2E against a booted iOS 18.5 sim + a worktree tool-server, driving the real client materializer path: - in a project, co-located server → `<projectRoot>/.argent/recordings/…mp4` (valid h264) - in a project, forced remote download (`GET /artifacts/:id`) → same durable dir, temp cache left empty - outside a project (HOME redirected) → `~/.argent/recordings/…mp4` - Root `tsc --build`, prettier, and eslint all clean.

Ignacy Łątka	f85d3843aa	feat(screen-recording): draw touch gestures into the recording (#549 ) ## What Draws the touch gestures argent drives directly into the screen recording, so a captured video shows where each interaction landed instead of a UI reacting to an invisible finger: - a pulse marks each tap - a fading comet trail follows a swipe / drag - paired markers show the two contact points of a pinch / rotate On by default; pass `showTouches: false` to `screen-recording-start` for a raw, overlay-free capture. ## How simulator-server already has a touch visualizer behind its `pointer` cargo feature (the binary argent bundles ships with it). It renders the markers into the very MJPEG stream this recording pipeline already consumes — nothing is composited host-side, and it's driven by the touch events argent already sends. This PR just turns it on for the life of a recording: - `screen-recording-start` builds a small `PointerControl` from the resolved simulator-server handle and hands it to `startCapture`. - The overlay is enabled right after the encoder goes live (so the first interaction is already drawn) and restored to off when the capture ends — stop, time-limit cap, encoder crash, or session teardown all run the same disable path, so it never outlives the recording it was enabled for. - Two thin client helpers (`setPointerVisible`, `setPointerTrail`) POST to simulator-server's `/api/pointer`. They're best-effort: a build without the feature (or a remote sim) just yields a `warning` at stop and a normal overlay-free video, never a failed recording. ## Verification - Unit — `screen-recording.test.ts`: 49 pass, incl. 10 new covering enable-at-start / disable at stop, cap, unexpected exit, and dispose; the `pointerFailed` warning; the no-control path; and the `/api/pointer` wire format (`{show}` / `{trail}`, ok/error/throw handling). - Static — `tsc` (src + `tsconfig.test.json`), eslint, prettier, full workspace build all clean. - E2E — drove the real tool-server → the bundled (production) simulator-server on an iOS 18.5 sim: - `showTouches: true` + a slow swipe → a translucent pointer bubble is rendered onto the screen at the touch point in the recording. - identical swipe with `showTouches: false` → paging still happens, no bubble — proving both the toggle and that stop restored the overlay to off (the control clip never re-enables it, yet draws nothing). --- Stacked on #548 (static-frame trimming) → base branch `feat/screen-recording-trim`.

Ignacy Łątka	82f6eb16b0	feat(screen-recording): trim static stretches out of the recording (#548 ) > Stacked on #517 (`feat/screen-recording`). Review/merge that first; this PR's diff is against that branch. ## What Trims stretches where the screen doesn't change out of the recorded video. A recording left running across waits, slow navigation, or agent thinking time used to come back padded with dead air; now a long session with only brief activity comes back as a short clip. ## How The frame pump already re-emits the last frame on a wall-clock schedule to keep the timeline honest. This adds a change detector on top: - Each frame is compared to the last one byte-exact (a reference check short-circuits the common "no new frame arrived" case, so only genuine arrivals pay the compare). Exact byte equality is stronger than a hash — no collisions — and flags a change down to a single pixel, matching "something moved, even by a couple of pixels." - The first second of every still stretch is kept (pauses read naturally), then unchanged frames are dropped until the screen moves again. - Active stretches still play at real time: the wall-clock pacer is re-anchored whenever a dead stretch is skipped, so the gap yields no output frames rather than a catch-up burst of the next frame. On by default. `trimStatic: false` on `screen-recording-start` keeps a faithful real-time recording (e.g. to measure how long something took on screen). `screen-recording-stop` now returns the trimmed length as `durationMs`, plus `wallClockMs` and `trimmedMs` when trimming removed anything. ## Verification - Unit: 39 tests in `screen-recording.test.ts` (7 new trim cases: default-on, grace-window kept, no-trim control, resume-the-moment-the-screen-changes, byte-identical-new-frame-stays-trimmed, duration reporting, fields-omitted-when-off). Full tool-server suite green (2817). `tsc --build`, `typecheck:tests`, eslint, prettier clean. - E2E on a live tool-server (iOS 18.6 sim): - 23s idle-heavy session (motion → 15s idle → motion) → 1.47s clip, `trimmedMs` 21930, with the real transitions intact (44 distinct frames — above the 30-frame grace floor, proving post-grace motion is kept). A `trimStatic:false` control of the same pattern returned the full 23s / 691 frames. - 8s continuous burst-motion session → 2.1s across multiple motion bursts (not collapsed to the 1s floor). - Cross-check: ran ffmpeg's own `mpdecimate` (duplicate-frame detector) over the same untrimmed footage — it kept ≤ what this trim keeps, confirming the trim is faithful, never over-aggressive (byte-exact is deliberately more conservative than mpdecimate's near-duplicate heuristic, so smooth animation is preserved while only frozen stretches are dropped).	2026-07-23 21:45:42 +02:00
Ignacy Łątka	2251c7cf46	feat(screen-recording): screen-recording-start/stop tools with per-call stop reminders (#517 ) ## What Adds a `screen-recording-start` / `screen-recording-stop` tool pair (naming follows `native-profiler-start/stop`) that records the device screen to an mp4 and returns it as a downloadable artifact. Capture runs through simulator-server — the same backend `screenshot` and every interaction tool already drive. simulator-server publishes the device screen as an MJPEG stream (`/stream.mjpeg`), so recording needs no platform-specific recorder: the tool-server subscribes to that stream, paces the frames onto a fixed 30 fps timeline, and pipes them into a single ffmpeg process that encodes — and watermarks — straight to the final mp4. The stream is multi-subscriber, so a preview window can stay open on the same device while recording. - One path for every device simulator-server drives — iOS simulators, Android emulators, and physical Android devices. - Native resolution, constant 30 fps — h264, `+faststart`, no post-processing pass. - Session state lives in a per-device `ScreenRecordingSession` blueprint (mirrors the native-profiler session): time-limit cap with auto-finalize, unexpected-exit recovery (a capture that ended on its own is still retrievable via stop), always-startable state reset on stop, and dispose-on-shutdown cleanup through the registry. ## Why the frames are paced host-side A device only emits a frame when the screen changes. Pointing ffmpeg straight at the stream therefore produces a video whose length is the sum of the moments something moved — a still screen collapses to a fraction of a second — and an ffmpeg blocked on a silent socket does not answer a stop signal promptly either (measured: 12 s late). Re-emitting the last frame on a wall-clock schedule fixes both: video duration always equals real elapsed time, and stop is a stdin EOF that finalizes in ~60 ms. Duplicate frames cost almost nothing once encoded (a 10 s recording of a static screen is ~1 MB). ## Finishing pass folded into capture The Argent watermark (logo + `By @swmansion`, bottom-left, sized relative to the frame) is stamped by the same ffmpeg invocation that encodes the capture, so there is no second encode and no temp intermediate. Its colour is chosen per pixel from the background luma underneath it — the white logo over dark areas, a runtime-derived near-black copy over light areas — so it keeps maximum contrast against whatever is behind it. It sits at 20 % opacity and is opt-out via `argent disable video-watermark` (read when the recording starts). Frame geometry comes from the first JPEG's SOF header, so no `ffprobe` is needed. ffmpeg is now the recorder rather than an optional finisher, so a missing ffmpeg fails `screen-recording-start` up front with an install hint instead of silently degrading the output at stop time. ## Reminder plumbing While a recording is running — or ended on its own but was never retrieved — every tool result carries a `note` telling the agent the recording is still going and how to stop it. It rides the same `note` field as the update reminder but is per-call and unsuppressed; both notes compose when they coincide. The note text switches to "already ended, retrieve the file" once the cap fires or the capture dies. ## Skill New `argent-screen-recording` skill (+ routing stanza in `rules/argent.md`): documents the start → interact → stop workflow and instructs the agent to schedule its own reminder/wakeup for the expected end of the recording immediately after starting one (harness reminder tool if available, otherwise a background `sleep` whose completion notification pulls it back). Scores 10/10 on `scripts/grade-skills.mjs`. ## Verification - Unit: 45 tests across `screen-recording.test.ts`, `mjpeg-stream.test.ts`, `watermark.test.ts`, `http-recording-note.test.ts`; full tool-server suite 2808 tests / 280 files green; `tsc --noEmit -p tsconfig.test.json`, root `tsc --build`, eslint, prettier all clean. - E2E on a live tool-server (`POST /tools/...`), driving real interactions between start and stop: - iOS sim (iPhone 16 Pro Max, iOS 18.5): 1320×2868 h264, `r_frame_rate=30/1`, 338 frames, container duration 11.27 s vs reported `durationMs` 11314 — within 50 ms of wall clock. Extracted frames show real screen content (mid app-switcher animation) with the watermark rendered light-over-dark. - Android emulator (Pixel 3a, API 34): 1080×2220 h264, 30 fps, 353 frames, duration 11.77 s vs `durationMs` 11793 — within 30 ms. 512 KB for a mostly-static home screen. - Static screen (no interaction at all, 10 s): 300 frames, duration exactly 10.000 s — the case the previous `recordVideo` implementation reduced to ~0.03 s. - Long silence then activity (15 s untouched, then an app launch): stream survived, no warning, frames after the silence show the new screen. This caught a real bug during review — the connect timeout was also acting as a socket inactivity timeout and tore the stream down at 10 s of stillness; fixed and covered by a regression test that fails without the fix. - Time-limit cap: `timeLimitSeconds: 5` self-finalized at 4.97 s / 149 frames, the per-call note flipped to "already ended (it hit its 5s time limit)", and a stop issued 11 s later still returned the video with the matching warning. ## Not supported (capability-gated with clear errors) tvOS simulators, physical iPhones, Chromium apps, Vega, and remote (`remote:`-prefixed) simulators — none of them expose a readable frame stream. --------- Co-authored-by: Ignacy Łątka <claude-hubert.gancarczyk@swmansion.com>	2026-07-23 21:14:37 +02:00

The escape-cooking fixture's comment cited flow-add-step.ts as a currently-shipping example of a `\n` description; main's flow rewrites reworded that description, so the citation is stale. The comment now leans on the fixture alone instead of any live tool's wording. No code change - `npm run test:scripts` still 59/59.	2026-07-23 19:40:07 +02:00
Aayush Gautam	3795cb84fb	fix(ios-profiler): stop native-profiler-stop being aborted mid-packaging (#529 ) ## Problem `native-profiler-stop` fails with `No active native profiling session found. Call native-profiler-start first.` while xctrace is still recording — #248, #250, #330. Those were closed on the 0.12.1 `--all-processes` workaround (#380), which fixed trace finalization but not this. The tool isn't declared `longRunning`, so the MCP adapter applies its per-request timeout: ```js fetchTimeoutMs: meta?.longRunning ? null : FETCH_TIMEOUT_MS, // mcp-server.ts:222 ``` A stop that runs past 30s is aborted and retried (`MAX_RETRIES = 4`). The retry runs against the session state the first call has already cleared, hits the `!api.profilingActive` branch and throws. The message points at session tracking; the actual failure is the timeout. Every failed stop I have logs for lands at 30–34s: `durationMs: 33639` in [#330](https://github.com/software-mansion/argent/issues/330), and 30276 / 30605 / 31019 / 31914 locally. Stop can't fit in 30s on Xcode 26.4+. Since #380 the capture is host-wide rather than app-scoped, so the bundle is much larger — ~55MB per 10s of recording here, 385MB for 90s — and xctrace needs ~22s to package even the 10s case before the four export passes start. `STOP_GRACE_MS` has the same problem from the other side: at 30s xctrace is SIGTERM'd mid-package, and the bundle it leaves behind fails to export. ## Fix Declare the tool `longRunning`, and raise `STOP_GRACE_MS` to 300s. The grace is a ceiling rather than a fixed wait — a fast package still returns as soon as xctrace exits — so this only changes captures that were previously killed. With both applied a 90s capture stops and exports cleanly in ~2–4 min, and a 40s capture returns inline. ## Note The abort-and-retry sequence is inferred rather than captured directly. What's observed: `MAX_RETRIES = 4`, the uniform ~30s durations, and `tool-server.log` showing the `did not respond to SIGINT` warning — written after the throw site — logged 184ms before the failure was returned. One execution can't produce that ordering. ## Testing - `npm run build` and eslint clean on changed files - `npm test -w @argent/tool-server` — 2727 tests / 273 files pass - Verified on Xcode 26.5 / iOS 26.5 simulator against a bridgeless RN app: start → interact → stop → analyze now returns a populated report with `errors: {}`	2026-07-23 18:32:44 +02:00
Jakub Piasecki	e006e68c81	fix(tool-server): tag gesture-pinch/gesture-rotate as ios/android in run-sequence (#541 ) Both gestures appear to be supported on Android: https://github.com/software-mansion/argent/blob/5d3f7bc62b278c03f3e63b45387cb41b937185c9/packages/tool-server/src/tools/gesture-pinch/index.ts#L54 https://github.com/software-mansion/argent/blob/5d3f7bc62b278c03f3e63b45387cb41b937185c9/packages/tool-server/src/tools/gesture-rotate/index.ts#L44	2026-07-23 08:02:00 +02:00
Jakub Piasecki	f32659df31	feat(flow): pinch directive (#545 ) Adds a selector-targeted pinch-zoom directive to flows: `pinch: { on?, scale }`. `on` resolves like `tap` (settled tree + auto-wait); omitted, the pinch centers on the screen. `scale > 1` zooms in, `< 1` zooms out. ## Design Options-map only, no bare form. `tap: "Map"` is unambiguous; `pinch: "Map"` isn't (in or out?), so the parser requires `{ on?, scale }` and rejects a bare selector with authoring guidance. Validity checks, not policy caps. `scale` must be finite, > 0, and ≠ 1 (a no-op scale is almost certainly a mistake) — but there is deliberately no magnitude cap. An extreme scale decomposes logarithmically into equal-ratio sub-gestures of ≤4× each, chained with a 250 ms recognizer-reset delay (`scale: 1e6` is just 10 gestures). Pure geometry module. All placement math lives in `flow-pinch-geometry.ts` as deterministic data-in/data-out functions (no device access), so tests drive it with synthetic centers, spans, and edge guards. Per sub-gesture, a horizontal and a vertical candidate are built from the axis-matching target dimension (normalized X and Y are different units, so never `min(width, height)`), and the better one is dispatched. Edge safety scores, it never rejects. Per-platform system-edge guards (wider on Android's back-gesture zones) demote candidates in ranking but never fail a step: viable travel beats edge safety (a risky-but-perceptible gesture beats a safe no-op the recognizer ignores), then fully-safe with the most travel, then motion parallel to the violated edge (edge swipes need motion away from the edge). Guards are resolved once per directive and passed as data — the seam for a future per-device query. The only geometry failure is literally zero on-screen finger travel; a tiny target is still attempted. Centroid drift near edges. When expanding fingers would leave the screen, the centroid drifts inward — only on the moving axis, and only as far as needed. `gesture-pinch` grows optional `endCenterX`/`endCenterY` to interpolate the centroid alongside separation; omitted, behavior is unchanged. Open-loop by design. There is no "current zoom" to read back, so the directive doesn't try to verify the multiplier — flows assert on the resulting UI instead. Platform rejections. Vega is remote-driven (no touch input) and Chromium has no uniform pinch-zoom mapping for a desktop app (ctrl+wheel or app-specific controls) — both fail upfront with guidance to drive the app's zoom UI directly. ## Tests Unit tests cover the geometry module (decomposition, candidate construction, edge-guard ranking), the directive end-to-end against a fake device, and the `gesture-pinch` centroid-drift interpolation.	2026-07-23 07:44:26 +02:00
Ignacy Łątka	87a7e77c1f	fix(tool-server): remove self-referential node_modules symlink committed in #476 (#537 ) ## What `packages/tool-server/node_modules` is tracked in git as a self-referential symlink — mode `120000`, target `/Users/.../packages/tool-server/node_modules` (it points at itself). It was introduced in `300bc30e` (#476) and is the only tracked `node_modules` in the repo; sibling packages have plain empty dirs. Every clone/pull of `main` now materializes a circular ELOOP link that breaks any recursive directory walker (`find`, globbers, bundlers, backup tools). Runtime is unaffected — deps hoist to the root `node_modules`, so the loop is silently bypassed. ## Why it slipped past `.gitignore` The `node_modules/` and `packages//node_modules/` rules have a trailing slash → directories only. Git treats a symlink as a file (blob), so neither rule matched and the path was addable → it rode into #476. `git check-ignore` confirmed it was NOT ignored. ## Fix - Remove the tracked self-symlink. - Drop the trailing slash on both ignore rules so a `node_modules` of any* type (dir, file, or symlink) is ignored — verified with `git check-ignore` that a symlink at `packages/*/node_modules` is now refused. No runtime code touched.	2026-07-22 19:59:25 +02:00
filip131311	7f85f996aa	fix(tool-server): defer to an existing server on EADDRINUSE instead of crash-looping (#533 ) ## Summary Fixes bucket B of the 0.16.0 crash telemetry — the `toolserver_bind` / `EADDRINUSE` restart loop. It's the largest crash volume (~817 events, one machine alone = 785) even though it's a narrow user set (10). Companion to #531 (which fixed the widespread multi-user bucket A). ## Root cause (reproduced live) The main HTTP listener's `server.on("error")` handler routed every bind error through `crashShutdown` (exit 1). When a second tool-server starts on an already-owned port, that exit just feeds a supervisor respawn → re-bind → crash, forever. The telemetry signature was puzzling: all these crashes are `crash_phase=serving` with ~1s uptime and 0 tool calls — i.e. the listener bound successfully and then died. I reproduced it: on macOS, a second tool-server process's `listen()` momentarily succeeds (the `listening` callback runs → `listening=true` → phase `serving`), and then the server emits an asynchronous `EADDRINUSE`. So the redundant instance binds, immediately errors, crashes, and the supervisor loops it (~1s each, 785× on one machine). Live A/B on the compiled `dist` (isolated port, telemetry disabled), server A up then a second server B on the same port: ``` buggy (current 0.16.0): B: "Tools server listening ..." → "Failed to bind ... EADDRINUSE" → exit 1 (→ respawn loop) fixed: B: "Tools server listening ..." → "deferring to it (redundant instance)" → exit 0 ``` A survives in both. ## Fix Handle `EADDRINUSE` specifically instead of crash-looping: - Probe the port for a healthy argent tool-server (`GET /tools` → 200, or 401 when a token is configured). - If a healthy peer answers, this instance is redundant → shut down cleanly (`shutdown(0)`) and defer to it. This removes it from the `reason:"crash"` restart-loop population entirely. - If nothing healthy owns the port (a foreign holder, or a wedged peer that doesn't answer within the probe timeout) → still crash, so a genuinely stuck port stays visible. - `EACCES` and all other server errors crash exactly as before. It also corrects the now-false comment claiming these crashes are phased `startup` ("the listen callback never ran"). Telemetry and the live repro prove the bind succeeds first, so `listening=true` and the phase is genuinely `serving`. ## Testing - New unit tests for `probeArgentToolServer`: peer answering 200 or 401 → `true`; foreign 500, connection-refused, and wedged/timeout → `false`. - Full tool-server suite 2731 green; `tsc` + `eslint` clean. - Live A/B above, on the built dist. ## Note on scope This is a robustness fix that breaks the loop for the redundant-instance case (the dominant one). The precise reason macOS lets a second process's bind succeed-then-error asynchronously (vs. failing immediately, as same-process contention does) is a kernel/loopback timing detail; the fix does not depend on it — any `EADDRINUSE`, immediate or deferred, now defers-or-crashes deterministically rather than hot-looping.	2026-07-22 16:56:54 +02:00
Ignacy Łątka	7400179b5b	Windows support: Android + Chromium host control plane (#421 ) ## What Makes Argent run on Windows. iOS Simulator is macOS-only (Apple), so on Windows that means the Android + Chromium host control plane. The blocker was twofold: (1) no Windows `simulator-server` binary, and (2) POSIX-only assumptions in the tool-server. Companion radon PR builds the binary and runs the Android emulator E2E on Windows: software-mansion/radon#134. ## Changes Windows-aware tool-server / resolver / bundling - New shared `commandOnPath()` helper — `where` on Windows, `command -v` via `/bin/sh` on POSIX. `android-binary`, `check-deps`, and `vega-cli` previously hardcoded `/bin/sh`, which never matches on Windows. - `android-binary`: append `.exe` to `adb`/`emulator` in the `$ANDROID_HOME` fallback; probe `%LOCALAPPDATA%\Android\Sdk` (Android Studio's Windows default). - simulator-server resolver + dispatcher + `bundle-tools` + `download-simulator-server.sh`: ship and resolve `simulator-server.exe` on `win32` (new `simulatorServerBinaryName()`), add `win32` to the bundled host keys, add the `simulator-server-argent-windows.exe` download target with PE arch validation. - `stop-metro`: resolve listening PIDs via `netstat -ano` on Windows (`lsof` is POSIX-only and threw ENOENT). - `adb.ts`: AVD root resolution used `$HOME` + `startsWith("/")` (rejects `C:\…`); now `os.homedir()` + `path.isAbsolute()`. - `boot-device`: the emulator was spawned `detached` with `stdio:"ignore"`; on Windows a detached emulator with NUL stdout/stderr never reaches `sys.boot_completed` (verified on `windows-latest`: the identical flag set boots fine with real handles, hangs with NUL). Redirect the detached emulator's output to a temp log file on win32. POSIX keeps `"ignore"`. Tests — cross-platform unit coverage for `commandOnPath` (both branches), win32 `.exe` Android resolution, win32 `.exe` simulator-server resolution, and a win32 AVD drive-path case; dep-gate tests now mock at the `commandOnPath` boundary so they're platform-agnostic. CI — `windows-e2e.yml` (`windows-chromium` on `windows-latest`): runs the resolver/dep unit tests natively on Windows, confirms `adb.exe` resolution via the SDK root, then drives a real headless Chrome over CDP through the tool-server (discover → screenshot → describe → tap → observe the DOM mutation). Flow in `scripts/ci/windows-chromium-e2e.mjs` (also runnable locally / in Docker). The `simulator-server.exe` build + the full Android-emulator E2E on Windows live in radon CI (the binary's source is the private radon repo). ## Verification (all green) - Chromium control plane on real Windows (`windows-latest`): `✓ discovered chromium-cdp-9222 → ✓ screenshot → ✓ describe → ✓ gesture-tap → ✓ DOM mutation observed`. Resolver/dep unit tests run natively; `adb.exe` resolves via the SDK root (it's not on PATH on the runner — the gap the resolver closes). - Android emulator on real Windows (radon#134, `windows-latest` / WHPX): the real Argent path — `boot-device` → `{ booted: true }` → screenshot via `simulator-server.exe` → gesture-tap — all green. (The boot-device fix above is what makes the detached emulator reach `boot_completed`.) - Local clean-room E2E: the Chromium flow runs green in a headless Linux Docker container (fresh `npm ci`, no host pollution). - No regressions: full tool-server suite (1624) + native-devtools-ios (16); ESLint/Prettier/typecheck clean; Wayland E2E (Linux AVD boot) and Vega VVD E2E still pass (they exercise the changed `adb.ts` / `boot-device.ts` / `vega-cli.ts` paths). ## Notes Android-emulator E2E needs WHPX nested virtualization — confirmed available on the current hosted `windows-latest` image (Server 2025); the emulator boots hardware-accelerated in ~3 min. --------- Co-authored-by: Ignacy Łątka <claude-hubert.gancarczyk@swmansion.com> Co-authored-by: Ignacy Łątka <latekvo@users.noreply.github.com>	2026-07-22 13:53:32 +02:00
filip131311	8d2a499eaf	Project-scope configuration with schema-driven merge + `argent config` (#534 ) ## Summary Adds a general, scoped configuration system on top of the shared `config.json`, plus a universal `argent config` command to manage it. Motivated by the discussion on #401 (iOS device set): config that needs to work naturally with the MCP server should be read off disk at runtime like telemetry consent is — not threaded through CLI flags/env and a kill-and-respawn dance. This lands the reusable machinery; the device-set becomes a one-line schema entry + a runtime reader on top of it. Four pieces, matching the requirements: ### 1. Project-scope config files `config.json` now resolves at two scopes: - `~/.argent/config.json` (global, default) - `<project-root>/.argent/config.json` (project, resolved by the same `.argent`/`.git`/`package.json` marker walk as feature flags) `configFilePath` / `readConfigObject` / `updateConfig` take an optional `scope` (default `global`), so every existing caller is unchanged (telemetry, notices, lens). Per-scope lock + atomic write are preserved. ### 2. Schema-driven merged reads `getConfigValue(def)` reads each scope the value's schema entry allows, merges them under the entry's policy, and falls back to the entry's default. This is the reader consumers should call instead of poking at a single global file. The existing lens getters (`getRememberedAgent` etc.) are migrated onto it as the first live consumer — a repo can now pin its lens agent, falling back to the user's global choice. ### 3. A registration file for configurations (`config-schema.ts`) Adding a configuration is a one-liner: `key`, `description`, allowed `scopes`, a `parse` validator, and a `merge` policy. Merge presets: - `prioritize-local` (project wins) · `prioritize-global` (global wins) - `prioritize-restrictive` (booleans/numbers — opt-out/stricter wins) - `union` / `intersection` (arrays) - …plus an escape hatch: pass your own `(inputs) => value` function for a bespoke rule. ### 4. `argent config` — one universal command `argent config <list \| get \| set \| unset>` with `--scope global\|project` and `--json`. New configs are added as schema entries, not new top-level `argent` commands, to avoid bloat. Telemetry stays backward-compatible on its dedicated `argent telemetry` command (which also drains/resets the live client). It's surfaced read-only under `argent config` via a `manageCommand` guard — so `argent config set telemetry.enabled` refuses and points at `argent telemetry`, and a committed project file can never re-enable a global opt-out (`prioritize-restrictive`, global-only). ## Testing - Unit / integration: 71 configuration-core tests (merge presets + custom fn, dotted-path + prototype-pollution guards, scope merge, scope/validation/manage-command errors, `listConfig`, `coerceCliValue`) and 11 real-filesystem CLI tests driving the actual `config()` entry point across sandboxed HOME + project cwd. Full suites green: configuration-core 71, argent-cli 268, telemetry 281, argent 60. - Live, on the built binary (`node packages/argent/dist/cli.js …`): set global + project (from a deep subdir) → effective get returns the project value; per-scope gets return each file; both files land in the right place; `argent telemetry disable/enable` writes `config.json` and `argent config get telemetry.enabled` reflects it read-only; unknown-key / invalid-value / bad-scope errors exit non-zero with hints. - `tsc --build` across the workspace, prettier, and eslint (`--max-warnings 0`) all clean. ## Notes / follow-ups - Config-file reads are not yet fingerprint-cached the way telemetry's consent read is; a long-lived tool-server re-reads on each `getConfigValue`. Fine for CLI/low-frequency use; a hot runtime consumer (e.g. a future device-set reader) may want the same mtime/inode cache.	2026-07-22 12:47:42 +02:00

filip131311	5d3f7bc62b	fix(ci): check tcp ax-service at its platform-neutral bin/tcp path (#540 ) ## Problem Every Publish prerelease to npm (next) run on main has failed since #536 landed (e.g. [run 29897926322](https://github.com/software-mansion/argent/actions/runs/29897926322/job/88851967242)), blocking canaries — including the canary that would ship the ios-remote ax-service fix itself. The failing step is the sanity check: ``` test -x packages/argent/bin/darwin/tcp/ax-service ``` But the binary is fine — the job log right above the failure shows `✓ Copied ax-service (tcp) binary → bin/tcp/ax-service`. The whole pipeline deliberately uses the platform-neutral `bin/tcp/` slot, not `bin/darwin/tcp/`: - `scripts/download-native-binaries.sh` writes to `bin/tcp/ax-service` - `bundle-tools.cjs` copies from/to `bin/tcp/ax-service` - `axServiceBinaryPathTcp()` / `tcpBinDir()` in `native-devtools-ios` resolve `bin/tcp` on every host The neutrality is intentional: the tcp ax-service is a darwin/iOS-sim binary uploaded to and `simctl spawn`'d on the remote macOS orchestrator, so a Linux host must still resolve it — `bin/linux/tcp` would never match. Only the sanity checks (and their comments) got the path wrong. ## Fix - Point the check in `publish-next.yml` and `publish.yml` at `packages/argent/bin/tcp/ax-service` (the stable-release workflow had the identical wrong path and would have failed the same way on the next release). - Correct the comment claiming `axServiceBinaryPathTcp()` resolves `bin/darwin/tcp`. Note: `packages/argent-private/.github/workflows/build-native-binaries.yml:549` has the same stale comment ("download-native-binaries.sh writes it to bin/darwin/tcp/ax-service") — that lives in the private submodule repo, so it isn't part of this PR. ## Testing Verified against the failing run's log (binary lands at `bin/tcp/ax-service`, check looks in `bin/darwin/tcp/`) and cross-checked all three path producers/consumers listed above. `grep -rn 'darwin/tcp'` now only matches comments explaining why the path is not used.	2026-07-22 10:21:14 +02:00
Juliusz Wajgelt	013d5b60c5	fix: get ax-service working on ios-remote (sim-remote --json spawn + TCP artifact diagnostics) (#536 ) ## Summary Three fixes that together get `describe` (and the other ax-service / native-devtools tools) working against ios-remote (`sim-remote`) devices — including from a Linux host. Reproduced end-to-end against a live remote iPhone 17 simulator over the QUIC relay. Before: `argent run describe --udid remote:<UDID>` returned an empty `ROOT AXGroup` with a misleading "reboot the simulator" hint. ### 1. `sim-remote spawn` output was never valid JSON (`fix(tool-server)`) `simctlSpawn` parses the CLI's stdout as one `{exit_code,stdout,stderr}` (or `{pid}`) JSON object, but `sim-remote spawn` only emits that when passed `--json`. Without it a non-detached spawn streams the child's raw output live, so `JSON.parse` throws `Unexpected end of JSON input`. This broke ios-remote describe at the first step: `remoteIosHost.bootstrapAx` runs `defaults write com.apple.Accessibility …` through a non-detached `simctlSpawn`, which failed before the ax-service daemon ever started — surfacing only as an empty AX tree. Fix: pass `--json` unconditionally (no-op for the already-JSON `--detach` path). ### 2. The tcp ax-service was resolved/packaged under a host-platform dir (`fix(native-devtools-ios)`) The tcp `ax-service` is a darwin/iOS-simulator binary that is uploaded to and `simctl spawn`d on the remote macOS orchestrator, so it's needed on any host platform. But it was resolved (and packaged) under `bin/<hostPlatform>/tcp` via `platformBinDir()`, so a Linux host looked at `bin/linux/tcp` and never found the darwin-built binary — the ios-remote path was effectively macOS-host-only. (The tcp dylibs were already neutral at `dylibs/tcp`.) Moved it to a platform-neutral `bin/tcp`, mirroring `dylibs/tcp`, and rewired every producer/consumer: - resolver: `platformTcpBinDir()` → `tcpBinDir()` = `BIN_DIR/tcp` - `native-devtools-ios/scripts/build.sh`: `bin/darwin/tcp` → `bin/tcp` - `scripts/download-native-binaries.sh`: `TCP_BIN_DIR` → `bin/tcp` - `packages/argent/scripts/bundle-tools.cjs`: copy from/to `bin/tcp` - tests assert the neutral location on both linux and darwin ### 3. Missing tcp artifacts were undiagnosable (`fix(native-devtools-ios)`) When a tcp artifact is absent (local/dev build, older package), the bare `... not found` error was thrown deep in the ax-service factory, where `describeIos` swallowed it and returned an empty tree plus `DEGRADED_HINT` — telling the agent to `boot-device --force`, a dead end. The only escape was discovering `ARGENT_SIMULATOR_SERVER_TCP_DIR` by reading source. Fix: `requireTcpArtifact` throws an actionable error naming the exact path, the override env var, and how to build it; `describeIos` surfaces that instead of the reboot hint. ## Testing - New `sim-remote-spawn-json.test.ts` — asserts `--json` on both plain and `--bin/--detach` argv, before the `--` separator. - `native-devtools-ios/test/index.test.ts` — the tcp binary resolves from the neutral `bin/tcp` on both linux and darwin; the not-found errors name their override env var. - `native-devtools-ios` (16) + ios/describe tool-server suites pass; typecheck, eslint, prettier clean. - Manual end-to-end against `remote:<UDID>` (darwin host): binary at `bin/tcp` → full tree from `source: "ax-service"`, no hint; binary removed → actionable `ARGENT_SIMULATOR_SERVER_TCP_DIR` hint.	2026-07-22 08:47:52 +02:00
Ignacy Łątka	300bc30e3d	fix(open-url): flag when a web URL may open the browser instead of an app (#476 ) ## Problem An agent calling `open-url` to deep-link into an app gets Safari instead: ``` open-url { "url": "https://bsky.app/profile/tvpworld.bsky.social" } → opens Safari ``` ### Root cause (not a wrapper bug — an iOS Simulator limitation) `open-url` on iOS is a thin wrapper over `xcrun simctl openurl`. An `https://` URL is a Universal Link, which only reaches a native app when that app is installed and verified for the link's domain. Two things bite here: 1. On the iOS Simulator, `simctl openurl` routes Universal Links to Safari even when the owning app is installed — a long-standing, documented limitation. Custom URL schemes (`scheme://…`) route reliably; Universal Links do not. 2. In the reported case the Bluesky app isn't installed at all, so Safari is the only valid handler — identical to tapping the link on a real iPhone with Bluesky absent. Reproduced on a booted iOS 18.5 sim: `simctl openurl <bsky https link>` launches `com.apple.mobilesafari`; the sim has zero third-party apps installed; `bluesky://…` fails with `-10814` (no registered handler), confirming absence. The real defect on our side: the result was always `{ opened: true }`, so a web URL that silently fell back to Safari was indistinguishable from a successful deep-link — the caller (an agent) believed it had reached the native app. There is no reliable way to observe which app actually handled the URL (Safari and other apps are invisible to the native-devtools socket), so the fix makes the ambiguity explicit rather than guessing. ## Fix - Add an optional `note` to the `open-url` result whenever a web URL (`http`/ `https`) is opened on a native device (iOS + iOS-remote). It states the URL may have opened in the browser and points to the reliable path: the app's custom scheme (`scheme://path`) or `launch-app` with the bundle id. - Update the tool description with the same deep-linking caveat. - Custom schemes, non-web schemes (`tel:`, `maps://`, `geo:`), and Chromium navigations are unaffected (no note). No URL rewriting — the URL is still handed to `simctl` unchanged. Scoped to iOS deliberately: Android App Links go through `am start` with a different verification/chooser path, and the reported symptom is iOS-specific. ## Verification - New unit tests (`open-url-deep-link-note.test.ts`, 4 cases): the helper returns the caveat for `http`/`https` (case-insensitive) and `undefined` for custom/non-web schemes; the iOS handler attaches `note` for the bsky https link (URL passed to `simctl` unchanged) and omits it for a custom scheme. - End-to-end against a live sim through the real `openUrlTool.execute`: - `https://bsky.app/profile/…` → `{ opened: true, url, note }` - `maps://?q=cupertino` (installed native handler) → `{ opened: true }`, no note - `bluesky://…` (not installed) → correct `FailureError` (existing behavior) - `tsc --noEmit`, `tsc --noEmit -p tsconfig.test.json`, and `prettier --check` all pass on the changed files.	2026-07-21 16:56:31 +02:00
filip131311	f0026ce6c8	fix(tool-server): stop native-devtools unix socket bind crashing the server (#531 ) ## Problem The per-UDID native-devtools unix listener binds with a bare `server.listen(socketPath)` and no `error` listener (`native-devtools.ts`, the `else` branch of the transport check). A bind failure — `EADDRINUSE` from a live/concurrent server on the same UDID, or `EEXIST` from a socket re-created in the window after the pre-unlink — fires an unhandled `'error'` event, which Node throws as an uncaught exception that crashes the whole tool-server at startup. The TCP branch right above it already guards its bind with `server.once("error", reject)`; `ax-service.startListener` does too. The unix branch was the one that didn't. ## Why it matters — 0.16.0 crash telemetry The crash-diagnostics shipped in 0.16.0 (`crash_fingerprint` / `crash_phase` / `error_syscall`) make this the clearly-dominant crash source. Scoped to `toolserver:stop`, `reason=crash`, `cli_version=0.16.0`: - 100% of crashes are socket/fs E-codes, none are logic bugs. EADDRINUSE (95%), EEXIST (4%), ENOSPC/EPIPE tail. - Fingerprint `dc063fe2` — the native-devtools socket bind site — throws both EADDRINUSE (65) and EEXIST (30) at `crash_phase=startup`, across ~14 distinct users. That's the widest-reach source by user count. (A separate single-user `toolserver_bind` restart loop accounts for most raw volume, but only one machine.) EEXIST at this site is the known concurrent-agent contention on `/tmp/argent-nd-<UDID>.sock` — a stale/racing socket file left by another server. ## Fix Extract the unix bind into `bindNativeDevtoolsUnixSocket(server, socketPath)`, mirroring `ax-service.startListener`: - Attaches an `error` listener so a bind failure rejects instead of throwing uncaught → routes into the factory's existing retry + failure-telemetry path, failing only this one service. - On `EADDRINUSE`/`EEXIST`, unlink the stale entry and retry the bind once — self-heals the unlink→listen race with a concurrent same-UDID server. - On any other failure (or a second failure), rejects with a coded `FailureError` (`NATIVE_DEVTOOLS_SOCKET_BIND_FAILED`, `failure_stage=native_devtools_socket_bind`) so it's cleanly classifiable in telemetry going forward. ## Testing - Unit (`native-devtools-socket-bind.test.ts`, 4 cases): free-path bind, stale-file self-heal, coded-FailureError on unbindable path, no-uncaught-throw when contending a live-held path. - Full telemetry + registry suites: 368 pass (new failure code accepted by the sanitizer allowlist). - Live A/B against built output — a live server holds the socket, then two child processes contend for it: - OLD (pre-fix `server.listen(path)`): exit 1, uncaught EADDRINUSE crash ← bug reproduced - NEW (compiled `bindNativeDevtoolsUnixSocket`): exit 0, self-healed and bound ← fix works - Bundled-artifact check: ran the esbuild `bundle-tools` step; the fix's retry logic and coded failure survive bundling intact in `dist/tool-server.cjs` (no dead-code-elimination surprise). 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-07-21 10:28:14 +02:00
Jakub Piasecki	a0d1bbb1e7	feat(flow): indent nested steps in reports by block depth (#524 ) Flow reports rendered every step flat, hiding which steps ran inside a `when:` block or a `run:` fragment. The tool-server now stamps `StepReport.depth` (+1 per block directive, omitted at top level) and the CLI/MCP renderers indent step labels and under-step lines by it: ``` ✓ 1 launch ✓ 2 when visible "What's new" — condition met ✓ 3 tap "Skip" ✓ 4 run dismiss [dismiss] ✓ 5 tap "OK" [dismiss] ``` Invariants: - Wire-compatible both ways — a flow with no block directives reports byte-identical to the pre-depth shape; a pre-depth server renders flat as before. - Skipped ≡ entered — skipped/errored/aborted blocks report the same depths as entered ones, keeping reports comparable run-to-run. - Untrusted wire data — renderers clamp depth (display cap, not a producer bound): hostile values render flat or at the cap, never throw or allocate huge strings. Also fixes a pre-existing bug: under-step warning/artifact lines now stay aligned past 99 steps. Tests pin depth on every producer path (entered/skipped/errored/aborted blocks, `run:` success/failure markers, `run:`-in-`when:`) and renderer alignment incl. the clamp boundary.

Ignacy Łątka	eb16d1c193	fix(tool-server): hard-kill (SIGKILL) timed-out iOS simctl calls so describe can't hang (#525 ) ## What happened An iOS `describe` call hung for ~24 minutes on the benchmark host, logging the incoming request and then going completely silent until the tool-server was killed. The iOS `describe` path shells out to `xcrun simctl` for nearly every step — `isTvOsSimulator` (`simctl list`), the ax-service bootstrap (`simctl spawn defaults …`), and the native-devtools env setup (`simctl spawn launchctl …`). Every one is guarded by `execFileAsync(…, { timeout: 10_000 })`, so on paper each is bounded to 10s. The problem is in Node itself: `execFile`'s `timeout` sends its `killSignal` (default `SIGTERM`) exactly once and never escalates to `SIGKILL`. When CoreSimulatorService wedges (which rapid clone/boot/delete churn induces), the `simctl` child ignores SIGTERM, its stdio never closes, and the promise never settles — so the "10-second timeout" never actually fires. There is no outer deadline on the `describe` tool to catch it, so the call hangs until the process is killed. ## Why this is the root cause (not a guess) - Static elimination: every JS-level guard on the describe path (ax-service's 10s connect/query timers, native-devtools' 5s RPC timers) would have fired and let `describe` return — and it never returned. That leaves only an `execFileAsync` whose OS-level kill failed to settle the promise. - Server logs: the hung process logged the POST, then nothing for 24 min until the kill — the exact signature of a stuck subprocess await with no error thrown. - Existing precedent: `adb.ts` already fixes this identical class of bug for Android via `ADB_KILL_SIGNAL = "SIGKILL"` (see its comment: "Node's execFile default kill signal is SIGTERM, which an `adb` process blocked on a hung daemon can ignore — leaving the parent waiting past the deadline"). The same fix was simply never applied to the `simctl` path. - Deterministic repro: `execFileAsync('sh', ['-c', 'trap "" TERM; …'], { timeout: 2000 })` never settles; adding `killSignal: "SIGKILL"` makes it reject at ~2006ms. Reproduces both the hang and the fix. ## The fix - Add `SIMCTL_KILL_SIGNAL = "SIGKILL"` to `simctl-config.ts` and pass it alongside the timeout on every describe-path `simctl` invocation (`ax-prefs.ts`, `ios-devices.ts`, `ios-host.ts`), mirroring `ADB_KILL_SIGNAL`. - Add the missing `timeout` + kill signal to `listRunningUIKitApplicationBundleIds`, which had no timeout at all (a latent forever-hang on the `native-devtools-status` path). - Add `test/ios-simctl-hardening.test.ts` pinning every describe-path `xcrun simctl` call to `killSignal: SIGKILL` + a finite timeout. ## Verification - `tsc --noEmit` clean (src + tests). - Full tool-server suite: 2670/2670 pass. - Confirmed the new test is a real guard: stripping the flag makes it fail, restoring makes it pass. ## Scope note This fixes the proven describe / native-devtools path. The same latent hang exists in other `simctl` call sites (`boot-device`, `launch-app`, `screenshot`, etc.) that use `execFileAsync` with the default signal — extending SIGKILL to the whole `simctl` surface is a reasonable follow-up but was kept out of this PR to stay scoped to the reported hang. One caveat: if `simctl` is ever stuck in true uninterruptible kernel state, even SIGKILL can't reap it until the syscall returns; the fully robust version would detach the await from the child via an independent deadline. SIGKILL matches the `adb` precedent and handles the realistic CoreSimulator-wedge case. --------- Co-authored-by: Ignacy Łątka <claude-hubert.gancarczyk@swmansion.com>	2026-07-20 19:26:33 +02:00
Piotr Krawiec	49e020bafd	fix(tool-server): resolve `ps` by absolute path so VVD dedup survives a sanitized PATH (#508 ) ## What A running Vega VVD registers a second adb transport (`emulator-<port>`), so it can surface in `list-devices` twice — once as `platform:"vega"` and once as `platform:"android"`. There's dedup logic (`resolveVvdShadowAdbSerials` + `filterVvdShadowsFromAndroid`) that drops the adb "shadow" row by matching the running VVD's console port — read from the process table via `ps` — against the adb serial's port. That dedup was spawning a bare `"ps"`, which relies on `PATH`. ## Why it broke An MCP server is frequently launched from a GUI / launchd context that inherits a sanitized `PATH` omitting `/bin`. There, `execFile("ps", …)` fails with `ENOENT`; the surrounding `catch` returns an empty port set, and the dedup silently no-ops — so the VVD shows up as two devices. It works fine from an interactive shell (where `/bin` is on `PATH`), which is why it doesn't reproduce in a terminal or in the existing tests. Observed: `list-devices` returned both a phantom `platform:"android"` `emulator-5554` and the real `platform:"vega"` device for a single running VVD. ## Fix Pin `ps` to its canonical absolute location, matching how the codebase already hardcodes `/bin/sh` (`android-binary.ts`, `vega-cli.ts`, `check-deps.ts`): ```ts export const PS_BIN = ["/bin/ps", "/usr/bin/ps"].find((p) => existsSync(p)) ?? "ps"; ``` Applied to all four `ps` spawn sites: - `vega-process.ts` — `listRunningVvdConsolePorts`, `listRunningVvdPids` - `vega-cli.ts` — `collectDescendantPids`, `pgidMembers` (same latent PATH fragility in the process-reaping paths) The bare-`"ps"` fallback is retained only if neither canonical path exists, preserving `PATH` resolution for an atypical layout. ## Tests - New regression test in `vega-process.test.ts` that strips `/bin` and `/usr/bin` from `PATH` and asserts the probe still spawns `ps` (a bare `"ps"` ENOENTs there — verified the test fails against the pre-fix code). - Updated the `list-devices.test.ts` mock to match `ps` by basename, since production now passes an absolute path. - `npm run build`, typecheck, lint (`--max-warnings 0`), and the full vega/list-devices suite (47 tests) all pass. ## Verification End-to-end `list-devices.execute()` under a launchd-style minimal `PATH` now returns exactly one device (the Vega), with no android shadow. `PS_BIN` resolves to `/bin/ps` and reads the VVD's console port even with `/bin` removed from `PATH`. --------- Co-authored-by: Piotr Krawiec <krawipio@amazon.pl>	2026-07-20 17:05:16 +02:00
Ignacy Łątka	cd4190b80e	Full tgz-only E2E harness (scripts/e2e-full) (#495 ) Now verified end-to-end on the real Mac: install/introspection/validation, the android tier (against a booted emulator), and the chromium tier all pass from a locally packed tgz; the rn tier auto-skips without `~/dev/bluesky` as designed. ## What this is A release-gating end-to-end harness under `scripts/e2e-full/` that starts from *only a `swmansion-argent-.tgz` bundle and exercises the whole product: the install flow, every CLI command, all 70 tools' argument validation, and a happy-path run of every tool against real devices. Intended to be run on the real Linux box and the real Mac before a release. Everything runs under a throwaway `HOME` + npm prefix, so it never touches the machine's real `~/.argent`, editor MCP configs, or global packages (safe on a shared box). It emits a JSONL log + a markdown coverage report and exits non-zero if any hard assertion fails. ## Phases \| phase \| needs \| covers \| \|---\|---\|---\| \| `install` \| npm + network \| `npm i -g <tgz>`, bundled binaries, `init` (global + `--local`), `update`, `uninstall`, telemetry, MCP-config generation \| \| `introspection` \| — \| `--version/--help`, `tools describe` for all 70 tools, feature flags, `server start/status/logs/stop`, `link/unlink` \| \| `validation` \| — \| per tool: missing-required / bad-enum / bad-type rejection (schema-driven, no hardware) \| \| `android` \| Android emulator \| happy-path of every touch/gesture/screenshot/app-lifecycle tool \| \| `chromium` \| Electron (bundled optional dep) + a display \| boots a generated Electron app; drives CDP tools (scroll/drag/tabs/cookies/storage) \| \| `rn` \| `~/dev/bluesky` + Android device \| debugger + react/native profiler + network chain against the real Bluesky app \| Tiers auto-skip with a recorded reason when prerequisites are missing. iOS / tvOS / Vega are intentionally out of scope for now. ## What I actually verified (real runs, Linux) - install 18✓/0✗, introspection 85✓/0✗ (all 70 `tools describe`), validation 81✓/0✗, chromium 24✓/0✗ (real Electron app + CDP). - Holistic run: 190✓ / 0✗ / 34∼, exit 0. Failure-gate confirmed (non-zero on fail), `bash -n` clean on all files, all 72 android/rn JSON arg literals linted. ## What I did NOT verify live (please scrutinize) - `android` and `rn` tiers were never run against a live device. The Android emulator would not stay up on my box (memory-constrained shared machine; QEMU threads hung seconds after boot across ~7 attempts). The code is complete and uses the same machinery the `chromium` tier exercised live, but it has not** been proven end-to-end. This is the main reason for the "not certain how well it works" caveat. - The RN tier's exact debugger/profiler arg shapes are derived from `tools describe`, not confirmed against a running Metro. ## Run it ```bash bash scripts/e2e-full/run-e2e.sh # everything applicable to this OS bash scripts/e2e-full/run-e2e.sh --skip-install --phase introspection,validation # fast offline core bash scripts/e2e-full/run-e2e.sh --phase android --android-serial emulator-5554 # inject a device ```	2026-07-20 16:43:34 +02:00
filip131311	66e051fe8b	fix(debugger): collapse a device's two ids onto one debugger instance (#528 ) ## The problem A device is reached through two id namespaces that name the same thing but are different strings: - the stable id the caller connects with — an iOS UDID / Android serial / Vega serial from `list-devices`; - the `logicalDeviceId` Metro's inspector-proxy echoes back for that connection (an opaque per-connection handle). `logicalDeviceId` is not derived by Argent — it is echoed verbatim from Metro (`js-runtime-debugger.ts`), and Metro never sees the UDID, so there is nothing to join on synchronously. The debugger service is cached by its URN, which embeds `device_id` verbatim: ``` JsRuntimeDebugger:<port>:<device_id> ``` `debugger-connect` took the UDID, returned the logicalDeviceId, and its description told callers to "forward it as device_id to all subsequent debugger-\ calls."* Following that instruction produced a different URN → a second `JsRuntimeDebugger` instance → a second `CDPClient`, a second console-log server, and a split log file — all for one device. The second attach also kicks the first off Metro's single-debugger-per-target proxy. Nothing deduplicated them. It only looked fine because with a single device on a Metro port, `selectTarget`'s single-device fallback quietly connects anyway; the split surfaces as "the debugger randomly drops" and logs landing in the wrong bucket. Secondary damage the same split caused: - `classifyDevice()` is shape-based and was fed the logicalDeviceId → an iOS device's forwarded id classified as Android in the capability gate + telemetry. - The docs asserted "iOS simulator UDID, Android logicalDeviceId" as if a UDID were the iOS logicalDeviceId — the repo's own test says the opposite. - `debugger-component-tree` printed the logicalDeviceId under a `udid:` label — teaching callers the wrong name. ## The fix — synchronous, within the existing `services()` design - Learn an alias `logicalDeviceId → connect-id` as a side effect of a successful connect (the one place both ids are known at once; see `utils/debugger/device-alias.ts`), and canonicalize `device_id` through it at every URN-building site. A forwarded logicalDeviceId now resolves to the already-open instance; unknown ids (the connect id itself, Chromium ids) pass through unchanged, so it is safe to call everywhere. No Metro round-trip on the hot path — `services()` stays synchronous. The alias is 1:1 (a logicalDeviceId is unique per connection) and is cleared on dispose. - Rewrite the `device_id` docs across `debugger-`, `network-`, and `react-profiler-`: pass the same list-devices id you connected with; the returned logicalDeviceId is informational (forwarding it still resolves, via the alias). Removes the instruction that caused the double instance and the false "UDID = logicalDeviceId" wording. - Fix the `debugger-component-tree` header* (`udid:` → `logicalDeviceId:`). Covered call sites (all that embed `device_id` into a Metro URN): `debuggerServiceRef` (connect/evaluate/status/log-registry), `debugger-reload-metro`, `debugger-component-tree`, `debugger-inspect-element`, `react-profiler-start` (+ its session URN), `react-profiler-stop`, `network-logs`, `network-request`. ## Verification Live, against a real iOS sim + Metro (my-app, RN 0.81.5), driving the branch tool-server directly: \| step \| result \| URNs instantiated \| \|---\|---\|---\| \| `debugger-connect { device_id: <UDID> }` \| returns `logicalDeviceId: d52ad36b…` \| `JsRuntimeDebugger:8081:<UDID>` \| \| `debugger-evaluate { device_id: d52ad36b… }` (forward the logicalDeviceId) \| `42` ✅ \| no new URN — reused \| \| counterfactual: `debugger-evaluate { device_id: some-unaliased-id }` \| `42` ✅ \| `JsRuntimeDebugger:8081:some-unaliased-id` — a distinct 2nd instance (the pre-fix behavior, reproduced) \| \| `debugger-component-tree { device_id: <UDID> }` \| header reads `logicalDeviceId: d52ad36b…` ✅ \| reused \| Unit — new `test/metro/device-alias.test.ts` covers the alias (learn / canonicalize / self-alias no-op / missing-id / forget) and that `debuggerServiceRef` yields the same URN whether called with the UDID or the forwarded logicalDeviceId. Full tool-server suite green (2726 tests). ## Not in scope Renaming the `device_id` param to `udid` (or vice-versa) — that is a breaking MCP wire change. This PR is additive: a forwarded logicalDeviceId keeps working, it just no longer opens a second connection. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-20 16:21:56 +02:00
Ignacy Łątka	78d3184ba8	fix(scripts): stop extract-tools dropping tools with long descriptions (#436 ) ## Defect `scripts/extract-tools.mjs` extracts MCP tool definitions by regex to feed the downstream `spidershield scan --tools-json` security scan. For each `id:` match it scanned only the next 2000 chars (`const descWindow = afterId.slice(0, 2000)`) for the `description:` value, and the description regexes require the string's closing delimiter to fall inside that window. Any tool whose description's closing delimiter sits past ~2000 chars is therefore matched as `null` and silently dropped - never emitted, never security-scanned. Two shipping tools hit this: - `run-sequence` (`packages/tool-server/src/tools/run-sequence/index.ts`) - a ~4285-char multi-line template-literal description whose closing backtick sits ~4324 chars past its `id:`. - `describe` (`packages/tool-server/src/tools/describe/index.ts`) - a ~2195-char description whose closing backtick sits ~2252 chars past its `id:`. Security impact: `describe` is the accessibility / DOM tree tool, exactly the kind of tool a `spidershield` scan should cover, and it was being silently excluded alongside `run-sequence`. A dropped tool is not a scan finding, so the gap was invisible. ### Repro (before) ``` $ node scripts/extract-tools.mjs \| grep -c '"run-sequence"' 0 $ node scripts/extract-tools.mjs \| grep -c '"describe"' 0 $ node scripts/extract-tools.mjs \| grep -c '"gesture-tap"' 1 # total tools emitted: 70 (run-sequence AND describe both missing) ``` ### After ``` $ node scripts/extract-tools.mjs \| grep -c '"run-sequence"' 1 $ node scripts/extract-tools.mjs \| grep -c '"describe"' 1 # total tools emitted: 72 (both captured, run-sequence's full 4285-char description intact) ``` ## Fix - Drop the fixed 2000-char lookahead. Each tool's `description:` is resolved at the same object-literal brace level as its `id:` by a forward scan that tracks brace depth over real code only: comments, string literals, template literals (with `${...}` interpolations skipped opaquely, recursively), and regex literals (prev-token heuristic incl. regex-permitting keywords like `return`) are skipped whole, so nothing inside them can open a fake string, shift the depth, or match as a `description:`/`id:` token. The value is then parsed to its actual closing delimiter, so a description of any length is captured in full. - Because matching is by brace scope rather than raw position, a stray `id:`/`description:` token can't corrupt extraction: a description-less tool can't borrow the next tool's description, an `id:` appearing inside description text or a comment can't truncate or overwrite anything, and an `id:` key nested inside a value object (e.g. `defaultPayload: { id: "example" }`) is neither emitted as a spurious tool nor allowed to drop the real one. - Captured text follows full JS cooked-string semantics: named escapes, `\xNN`, `\uNNNN`, `\u{...}`, identity escapes, line continuations, and template `\r\n`/`\r` -> `\n` normalization - the emitted (and security-scanned) text is the string the runtime renders. - A description value that is not a single plain literal - a concatenation, a `${...}` interpolation, a method/operator suffix (`"...".slice(0, 3)`), `as const` - is never emitted as a truncated/wrong literal: it warn-skips on stderr (stdout stays valid JSON for the scanner). Non-interpolated template-literal ids (`` id: `x` ``) are extracted; interpolated ids stay out of scope like const-reference ids. - Duplicate ids keep the first occurrence and warn (exported as a pure, unit-tested function). - The extractor stays dependency-free (node: builtins only): the tool-description-quality workflow runs it on a bare checkout without `npm ci`. - Output JSON shape is unchanged. ## CI guard Adds `scripts/extract-tools.test.mjs` (node's built-in test runner, wired into `npm run test:scripts`; 36 tests). Ground truth: the real-tree tests parse every tool source file with the actual TypeScript parser (a root devDependency, test-only) and require the extractor's output to equal the AST exactly - names and descriptions byte-for-byte. Any drop, corruption, or fabrication on a shape that enters the tree fails CI loudly, with no reliance on stderr warning formats and no false red from `id:`-like text in comments or strings. Two policy gates keep un-extractable shapes out of the tree instead of letting them silently leave the scan: a `description` that cannot be read statically (non-literal value, shorthand/getter/method/computed member, or a spread sibling that may carry/override it) and a plain-literal description written before its `id:` (the scan is forward-only) each fail with an actionable, file-naming message. Fixture tests pin the parsing rules independent of any real tool's wording - long descriptions (>4000-char value, >2000 chars of siblings between `id:` and `description:`), embedded `id:`/`description:` tokens, comments, keyword-position and sibling regex literals, division, nested templates and interpolation content, template/`as const` ids, the full escape suite, CRLF cooking, single-quoted forms, trim, warn-skip classes, and the duplicate-id warning. Each new fixture was verified to fail under a targeted mutation of the extractor. Note: tools registered with a const-reference / dynamic id (e.g. `id: AWAIT_UI_ELEMENT_TOOL_ID`) rather than a static literal stay out of scope for this extractor - a separate, pre-existing limitation unrelated to the description window, and one this static/lexical extractor cannot close soundly (it has no tool-scope knowledge, so a blanket warning on every `id: <identifier>` would also fire on legitimate nested non-tool keys like `{ id: someVar }` in a payload/example object). The full set currently taken out of the scan this way is `app-map-crawl`, `app-map-export`, `app-map-navigate`, `app-map-query`, `await-screen-idle`, and `await-ui-element`. A proper fix is a follow-up covering const-ref id resolution plus a real-tree emit-count and empty-stderr assertion so this silent-omission class trips CI if it ever regresses. ## Verification - `node scripts/extract-tools.mjs` -> 72 tools, `run-sequence` and `describe` both present (total 70 -> 72), byte-identical to the TypeScript-AST parse of the tree, no stderr warnings - `npm run test:scripts` -> all pass (`extract-tools.test.mjs`: 36 tests) - mutation checks: window-bounding, depth-anchor removal, trim removal, dedup neutralization, single-quote-branch neutralization each fail the suite - `npm run typecheck:scripts` -> clean - `prettier` + `eslint` on changed files -> 0 problems - lockfile: `npm install --package-lock-only --ignore-scripts` -> no diff (idempotent)	2026-07-20 12:56:44 +02:00
Jakub Piasecki	3f602a7a9b	feat(flow): conditional when blocks (#498 ) ## What A `when:` block runs a step list only when one condition holds — a UI condition (`exists`/`visible`/`hidden`/`text`, the await/assert shapes) or a static `platform` test. No else, by design: a block exists to restore determinism (dismiss an interstitial, reconverge), never to test two paths. Tap-if-present is a one-step block: `when: { visible: "Got it" }` + `steps: [tap: "Got it"]`. No per-step `optional:` — `when:` covers every directive once. The key is rejected at parse with a pointer to `when:`, not silently dropped (a Maestro habit that would leave a "can't fail" step hard-stopping the flow). ## How - The guard reuses the assert engine at the 1s grace (`timeout` is a parse error), so a skipped block barely costs a clean run. - Verdicts are evidence-based: no trustworthy read in the window → indeterminate → the step errors ("could not evaluate" is not "condition false"); a transient read failure after trusted reads showed the condition false stays a clean skip. - `platform` folds `ios-remote` into `ios` — the parser rejects that spelling, so the fold is the only way a guard matches a remote sim. - A skipped block reports one line per authored step, same shape for unmet guard, hard stop, or cancellation; everything goes through `pushReport`, so when lines stream live. Failures inside an entered block hard-stop as usual. - Results carry an explicit `aborted` flag; `ok` keys off fail/error/cancel, not skip lines. - Nesting is capped at 20, so a cyclic YAML alias is a structured parse error, not a stack overflow. ## Testing `vitest` 2546 pass (17 when-specific); `tsc --noEmit` (tool-server, argent-mcp, argent-cli), eslint, prettier clean.

Jakub Piasecki	8d633700d7	feat(flow): coordinate targets for tap and long-press (#504 ) ## Summary This adds raw normalized screen coordinates as first-class targets for both `tap` and `long-press`. Gestures can now target either an element selector or a point, while keeping the existing selector auto-wait and off-screen diagnostics. Supported forms include: ```yaml - tap: { x: 0.5, y: 0.6 } - tap: { on: { x: 0.5, y: 0.6 }, times: 2 } - long-press: { x: 0.5, y: 0.6 } - long-press: { on: { x: 0.5, y: 0.6 }, duration: 1200 } ``` ## What changed - Introduced a shared gesture-target parser for selector and point targets. - Added raw-point execution for `long-press` and shared point resolution between tap and long-press. - Validate coordinates as finite normalized `0–1` screen fractions, rejecting pixels, malformed points, mixed selector/coordinate maps, and unknown point keys. - Canonicalize option-bearing coordinate gestures under `on`, keeping option keys separate from target fields. - Preserve coordinate targets in recording summaries and flow progress reports instead of displaying an undefined selector. - Added serialization validation so recording cannot persist a flow that would fail when parsed for replay. - Updated the flow authoring skill and tool description with the new coordinate forms. ## Behavior notes - Raw points act immediately and do not resolve or observe the UI tree. - Selector targets retain settling, auto-wait, and the existing `scroll-to` hint when an element cannot be found. - Observation directives such as `type`, `await`, `assert`, and `scroll-to` remain selector-only. - The mixed spelling `tap: { x, y, times }` is now intentionally rejected; use `tap: { on: { x, y }, times }` instead. ## Validation - Full tool-server suite: 2,618 tests passed across 266 files. - Added parser, serialization, recording, touch execution, Chromium execution, reporting, and malformed-input coverage. - Tool-server build, test typecheck, ESLint, Prettier, and skill validation passed.	2026-07-17 14:48:29 +02:00
Jakub Piasecki	1a4f89cd5f	feat(flow): allow to compose all flows via `run:` (#507 ) ## Summary `run:` accepted fragments only — an e2e flow (one starting with `launch:`) was rejected as a `run:` target. This lifts that: an e2e flow can now be nested via `run:`, its `launch` running inline (a real terminate + relaunch on native). Composition becomes uniform — any flow can be a reusable building block. ## What changed - `flow-run.ts`: dropped the `isE2eFlow` rejection in `execRunStep`; cycle / `MAX_RUN_DEPTH` guards still bound recursion. - `flow-add-step.ts`: the recorder now captures a recorded `flow-execute` of an e2e sibling as a portable `run: <name>` directive (was: raw `tool:` step). - `flow-utils.ts`, `argent-create-flow/SKILL.md`: updated docs/skill that said e2e flows can't be `run:` targets. ## Known limitation — Chromium Chromium `launch` boots an Electron app from a path, wired to the top-level flow only — so a nested chromium e2e flow doesn't boot its own app. Native nesting is correct; chromium nested e2e is unsupported. ## Testing Rewrote the two affected tests (composition + recorder). Full flows suite green (349 tests); `tsc --noEmit` clean.	2026-07-17 14:18:32 +02:00

filip131311	b50d51a2de	chore: bump workspace packages to 0.16.0 (#513 ) ## What Lockstep-bump all 16 `packages/` workspace packages (and the matching `package-lock.json` entries) from `0.15.0` → 0.16.0. ## Why The `packages/argent-private` submodule is already pinned at v0.16.0*, while the workspace packages sat at 0.15.0. This aligns the whole repo on the single 0.16.0 version. ## Verification - `node scripts/check-workspace-versions.mjs` → `All workspace packages are at 0.16.0.` - `git submodule status` → clean (no `+`), pinned at `v0.16.0`. - Lockfile diff is exactly 17 version-field swaps (no unrelated churn — a full `npm install --package-lock-only` regeneration was rejected because it introduced unrelated `"peer": true` churn from a newer npm). v0.16.0	2026-07-15 20:53:36 +02:00
filip131311	92b8c039c3	fix(flow): refuse invisible-only text selectors — record coordinates instead (#511 ) ## The bug (found in the 0.15.0 full-surface QA, on both the Android emulator and a physical S24) Recording a `gesture-tap` on an icon-font tab-bar item wrote a flow step that displays as an empty selector, with the coordinates gone: ```yaml steps: - tap: text: # ← actually U+E163, an icon-font Private Use Area glyph ``` and `flow-execute` then silently passed against target `""`, tapping an element no reader of the flow can predict. Root cause (hexdump of the QA-recorded file: `ee 85 a3` = U+E163): icon fonts expose their glyph as the element's accessibility label; `deriveSelector` accepted any label that survived `trim()`, so a PUA code point counted as "stable text". This violated the rewrite's own documented contract — "otherwise coordinates are kept with a warning" — whose fallback path existed and worked, but never ran for this case. ## The fix — one predicate, three layers `hasVisibleText()` (strip Unicode `Cf` format / `Co` private-use / `Cc` control, then trim; require something left): 1. `deriveSelector` — invisible-only label/value is not stable text; fall through to role, then to the recorder's existing kept-coordinates path. 2. `selectorToYaml` — the empty-text guard previously covered only the bare-string spelling; it now also rejects empty/invisible text on the strict `{text: …}` map form, so a hand-built selector fails loudly instead of writing an unreadable flow file. 3. `selectorSchema` — parse-side refinement, so flow files already recorded broken on 0.15.0 fail with an actionable message ("text must contain at least one visible character … select by identifier or role instead") instead of false-passing at replay. This also hardens the `await-ui-element` tool surface, which shares the schema. Text that merely contains an icon glyph alongside real text ("⟨U+E163⟩ Explore") stays valid throughout. ## Verification - Unit: `deriveSelector` PUA/ZWSP/mixed cases, serialize + parse rejection round-trips (explicit `\uXXXX` escapes, no invisible bytes in the test source). - Full tool-server suite: 2667 passed. - Live on the Pixel_9 emulator against the original QA repro (my-app tab bar, same coordinates): recording now produces `tap: {x: 0.75, y: 0.947}` with the documented "kept coordinates (brittle)" warning — the role fallback was correctly caught by the existing resolves-to-a-different-element guard — replay passes 2/2 on the coordinate targets, and executing the old broken YAML now fails parse with the visible-character error. 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-07-15 20:31:23 +02:00
filip131311	07427917e2	fix(launcher,lens): drop the npm postinstall — its jobs move to runtime (#510 ) ## Why Shipping any `postinstall` makes pnpm 10+ wall the install behind its build gate: `ERR_PNPM_IGNORED_BUILDS`, `pnpm install` exits 1, and `pnpm exec argent` is unusable until the user runs `pnpm approve-builds` — their first experience of argent is a bricked CLI. The same script is also silently skipped by `--ignore-scripts`, Yarn PnP, and locked-down CI, so anything correctness-relevant in it was already unreliable (the codebase says as much in several places, e.g. `runTrustingDisk`). Live-verified during the 0.15.0 QA: with all builds declined in pnpm 11, argent installs, inits, and serves MCP fine — the postinstall was never load-bearing for install correctness. Removing it means pnpm users never see the approve-builds wall for argent itself. ## What the postinstall did, and where it went \| Job \| New home \| \|---\|---\| \| SIGTERM a tool-server stranded by an upgrade that replaced its bundle dir (pnpm/yarn version-pinned layouts) \| `sweepDeadStateFiles` in the launcher's slow path now retires live servers whose recorded bundle is gone from disk, with the same pid-identity guard as `killToolServerForInstallDir` (never signal a recycled pid; keep unidentifiable live records reachable for `server stop`). Same-bundle in-place bumps were already self-healed by the disk-authoritative version gate. \| \| `chmod +x` node-pty's macOS `spawn-helper` prebuilds (shipped without the exec bit; first `pty.spawn` otherwise fails `posix_spawnp`) \| `ensureSpawnHelperExecutable()` in `lens-pty.ts`, run when the module loads, best-effort with the AppleScript fallback intact. \| \| Print the `argent init` hint \| Dropped — init flows drive the install, and the hint never printed on pnpm/PnP anyway. \| `ARGENT_SKIP_POSTINSTALL` in `update.ts` is kept deliberately: downgrades and pinned installs fetch older versions whose postinstall still exists and honors it. ## Testing - New `launcher-sweep.test.ts` (6 tests) exercises the sweep against real processes: live-server-with-deleted-bundle is terminated and its record unlinked; live server with intact bundle untouched; recycled-pid record kept, not signalled; dead-pid record unlinked; legacy slot untouched; a SIGTERM-trapping orphan doesn't hold the sweep (and the spawn lock above it) hostage for its kill grace window — the record is unlinked and the SIGKILL escalation runs in the background. - New `ensureSpawnHelperExecutable` tests (real fs, darwin-gated) verify the +x restore and silent failure; a regression test pins that `loadNodePty` tolerates req seams without `resolve`. - Full suites green in all touched packages: tools-client 154, installer 535, cli 248, mcp 76, argent 60. 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-07-15 20:26:39 +02:00

filip131311	f1331cf80d	fix(installer): unbreak pnpm local installs + stop self-fulfilling editor detection (#501 ) ## Problem Field report (pnpm setup): `npx @swmansion/argent init --local` - ✅ "updated argent 14→15", ✅ created `.mcp.json` + `skills-lock.json` - 🔴 did not add argent to `package.json` - 🔴 re-running the same command → `Local install failed.` + advice to run `pnpm add -D ...` manually - 🔴 init "persistently detects" Cursor and Codex on a fresh machine that never had them ## Root causes (each reproduced; confirmed against installer telemetry) 1. Stale-binary hijack — bare `npx @swmansion/argent` prefers an existing global install over the registry. A global 0.14 predates `--local` and `parseInitArgs` silently ignored unknown flags, so run 1 was a plain global-mode 0.14 init: it offered the 14→15 update, wrote mcp/skills files, and never touched package.json. That's symptoms 1–3 in one. 2. pm detection missed pnpm's modern markers — `pnpm init` (pnpm 10/11) writes only `devEngines.packageManager`, and no lockfile exists before the first install. Detection fell back to npm, whose own devEngines gate instantly rejects the install (`EBADDEVENGINES`, ~250 ms). This is the 221–537 ms `INSTALL_LOCAL_PACKAGE_FAILED` cluster in PostHog (8 events / 7 users last week). 3. Missing pm binary (cloned pnpm repo, machine has only npm) surfaced as raw `spawn pnpm ENOENT` plus manual advice that fails identically in the user's shell. 4. Self-fulfilling detection — Cursor/Codex `detect()` keyed on bare `~/.cursor` / `~/.codex` dirs, which argent itself creates (an `init -y` with nothing detected configures all editors; allowlist/skills writes too). Telemetry also shows a ~19 s failure shape where an identical manual retry succeeds (transient registry / pnpm first-run state errors). ## Fixes - Init flag parsing stays lenient: unknown flags remain silently ignored — aborting on them could break existing scripts/setups that pass flags an installed version doesn't know. The parser now also accepts the `--from=path` spelling, ignores a dangling `--from`, and keeps first-`--from`-wins semantics. The stale-binary hijack is addressed on the docs side (`@latest` in the README) rather than by a hard abort. - `detectProjectPackageManager` honors `devEngines.packageManager` (object + array forms) and `pnpm-workspace.yaml` — the latter ranked below real lockfiles so a stray file left by a pnpm→yarn migration can't outrank `yarn.lock`. - Missing-binary failures name the real problem ("This project uses pnpm, but the pnpm command was not found on PATH" + corepack hint). Windows detected via cmd.exe's "is not recognized" text, since `shell: true` never ENOENTs there. Other pm failures retry once. - Editor detection requires real evidence: a `.cursor`/`.codex` dir counts only if it holds something beyond argent's own artifacts (argent mcp.json entry, `permissions.json` allowlist, managed `developer_instructions`, bundled rules/agents/skills). Corrupt, unparseable, or empty content conservatively counts as user evidence. The stale-config sweep now scans all adapters so dead entries in no-longer-detected dirs still get pruned. - README: recommend `npx @swmansion/argent@latest init` and a `pnpm dlx` alternative (npm's devEngines gate blocks the outer npx in fresh pnpm-init projects). ## Testing - Live-tested a packed tgz under the exact repro conditions: fresh pnpm-init project A/B (published 0.15.0 fails EBADDEVENGINES in ~250 ms; this branch installs the devDependency correctly), missing-pnpm message, flag-parsing edges (`--from=` spelling, dangling `--from`), retry-on-transient-failure (flaky pm shim), detection flips (argent-only dirs incl. permissions.json → not detected; `argv.json`/`sessions/`/corrupt configs → detected), plus regressions: npm project local init, global-mode `init -y`, recovery of the broken post-0.14 state. - High-effort multi-agent code review of the diff surfaced 10 confirmed defects in the first iteration (permissions.json not whitelisted, corrupt configs misclassified as argent-only, pnpm-workspace.yaml outranking yarn.lock, `--from=` rejected, Windows ENOENT never firing, stale-sweep interaction, …) — all fixed and re-verified. - 493 argent-installer + 87 registry unit tests green (new suites for flag parsing, devEngines/workspace detection, detection evidence). 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-07-15 15:37:54 +02:00
Ignacy Łątka	af8476c0a9	feat(vega): support the JS-runtime debugger and network inspector on Fire TV (#502 ) Vega's React Native is a fork of RN 0.72, so it serves the legacy Hermes inspector rather than the post-0.73 (Fusebox) debugger. The `debugger-` / `view-network-` / `react-profiler-` tools were never gated for it, so every call against a VVD was rejected before any RN code ran: ``` Tool 'view-network-logs' is not supported on vega vvd (no vega support declared). ``` That gate turned out to be the only thing in the way for most of them. The concern that prompted this was that the network inspector needs the new debugger. It does not: argent's network inspector never touches the CDP `Network` domain, it monkey-patches `fetch` over `Runtime.evaluate` and reads back a global array. `Runtime.evaluate` has worked in Hermes since long before 0.73, so the network inspector is precisely the tool that is unaffected* by the missing new-debugger stack. ## What now works on Vega Gated in via `DEBUGGER_TOOL_CAPABILITY` (these need only `Runtime.evaluate`): `debugger-connect` · `debugger-status` · `debugger-evaluate` · `debugger-log-registry` · `view-network-logs` · `view-network-request-details` ## What stays gated off, and why `debugger-component-tree` · `debugger-inspect-element` · `debugger-reload-metro` · `react-profiler-` · `profiler-` Two different reasons, and it is worth keeping them apart: - `debugger-component-tree` and `debugger-inspect-element` are hard-blocked. They are the only two callers of `cdp.evaluateWithBinding`, i.e. they deliver their payload over `Runtime.addBinding` / `Runtime.bindingCalled`. RN 0.72's Hermes ACKs `Runtime.addBinding` and never installs the binding — confirmed on the VVD: after a successful `debugger-connect`, `typeof __argent_callback` is still `"undefined"`, and no `bindingCalled` ever fires. They would hang until timeout. - `debugger-reload-metro` and the profiler tools are simply unverified here. They do not use the binding (`reload-metro` is `Page.reload` plus an HTTP `/reload` fallback; the profilers ride `Runtime.evaluate` and the CDP `Profiler` domain). They share `RN_ONLY_TOOL_CAPABILITY` and stay out of scope rather than ship untested. Either way the capability gate turns a hang (or an unknown) into an immediate, explicit "not supported". `describe` remains the way to read on-screen structure on Vega. Worth noting for a follow-up: the component-tree data itself is reachable on RN 0.72 — walking the DevTools hook via a plain `Runtime.evaluate` returns the real fiber tree (640 fibers on the sample app). Component-tree is blocked by argent's transport choice, not by a missing runtime capability, so a non-binding fallback would unlock it. ## Two bugs this surfaced A Vega `device_id` could bind to another device's runtime. Vega's legacy inspector-proxy emits no `reactNative` block at all, so its targets carry no `logicalDeviceId`. `selectTarget` both matched `device_id` on `logicalDeviceId` and counted connected devices the same way — so a Vega device was invisible to the multi-device guard from #397: its id matched no target, the guard counted zero devices, concluded there was nothing to disambiguate, and fell through to the priority target. With a Fusebox iOS/Android app on the same Metro, that target wins the priority list, so `debugger-evaluate` would have run JS in the wrong app while `debugger-status` reported the other device's name and `isNewDebugger: true`. Devices are now keyed by `logicalDeviceId \|\| deviceName` (the legacy proxy always reports a name), so the guard sees them and refuses to guess. A lone VVD still falls back to its own targets. This is not Vega-specific: any RN ≤ 0.72 device was invisible the same way. Metro's missing project-root header. RN 0.72's Metro never sends `X-React-Native-Project-Root`, and `discoverMetro` treated a missing header as fatal — which took down evaluate, console logs and the network inspector too. The header only feeds source-map / `file:line` resolution, which degrades cleanly to no-location, so it is now optional. Platform-agnostic, not a Vega special-case: a missing source-map hint should never kill an otherwise working debugger session. That made `projectRoot: ""` a reachable state, which two source-resolution paths mishandled. `symbolicate` stripped the root with `file.replace(projectRoot + "/", "")`, which on an empty root degrades to `.replace("/", "")` and deletes the first slash anywhere in the path (`src/screens/Home.tsx` → `srcscreens/Home.tsx`). And `readSourceFragment` did fail closed, but only because `fs/promises.realpath("")` happens to reject where the sync API returns the tool-server's cwd — it now bails explicitly instead of leaning on that quirk. Both are reachable from `debugger-inspect-element` on any legacy Metro (not on Vega, where it is gated off). ## Verification Driven end-to-end against a real VVD (`amazon-6b8a…`) running the `react-native-multi-tv-app-sample` Vega app (Debug `.vpkg`, Metro reachable via reverse port-forward), through a tool-server built from this branch: ``` debugger-status -> connected: true, deviceName: kepler-device, isNewDebugger: false, projectRoot: "" debugger-evaluate -> "hermes=object fetch=function global=object" debugger-log-registry -> captured console.log "PR502_E2E_MARKER" === NETWORK LOGS (page 1/1, 2 total) === {id: rn-net-1} "GET /todos/7" 200 Fetch 98 B 55 ms {id: rn-net-2} "GET /users/3" 200 Fetch 520 B 17 ms view-network-request-details -> full request/response headers, status, timing ``` And the gated tools fail fast (0.02s) rather than hanging: ``` debugger-component-tree -> not supported on vega vvd debugger-inspect-element -> not supported on vega vvd debugger-reload-metro -> not supported on vega vvd react-profiler-start -> not supported on vega vvd ``` Re-ran the whole sequence against the fixed target-selection to confirm the single-VVD path still connects. Also run locally: `tsc --build`, `tsc --noEmit -p tsconfig.test.json`, `eslint . --max-warnings 0`, `prettier --check`, `grade-skills`, and the tool-server unit tests (199 files / 1740 tests). Tests added: `vega-target-routing` (the mis-route, using a target payload captured verbatim from the live VVD), `source-resolver-empty-root` (both empty-root paths), and `vega-debugger-capability` — which now drives the real `ToolDefinition.capability` fields and `resolveDevice` instead of a hand-written name↔constant pairing, pinning all 6 enabled and all 14 gated tools. The old version passed even with `debugger-status` wired to the wrong capability constant. Scope note: VVD only — no tool declares `vega: { device: true }`, so physical Fire TV hardware is untouched.	2026-07-15 15:36:12 +02:00
filip131311	70660378bb	feat(tool-server): type secrets via {{secret:NAME}} placeholders — plaintext never enters agent context (#506 ) ## Why Feedback: unlike Stagehand's `act("type %pw% into password", { variables: { pw } })`, argent had no way to type a credential without the LLM seeing the plaintext — which disqualifies it as a CI agent. In the MCP model the agent composes the `keyboard` call itself, so a plaintext password lands in six places: the agent transcript, `~/.argent/mcp-calls.log` (spyLog records full args + result), the flag-gated tool-server event log, the `typed` result echo, recorded flow YAMLs (committed to the repo), and the post-type auto-screenshot (plaintext back into context as pixels for non-secure fields). ## What `keyboard` and `paste` now accept `{{secret:NAME}}` placeholders in `text`, resolved server-side from `ARGENT_SECRET_NAME` environment variables: ```yaml # GitHub Actions env: ARGENT_SECRET_APP_PASSWORD: ${{ secrets.APP_PASSWORD }} ``` ```json { "udid": "<UDID>", "text": "{{secret:APP_PASSWORD}}", "key": "enter" } ``` Resolution happens inside the tool's `execute` — after every existing logging boundary — so spyLog, the event log, the transcript, and recorded flows all see only the placeholder, with near-zero extra redaction work: - `run-sequence` keyboard steps and flow `type` steps go through `invokeSubTool` into the same `execute` → covered for free. A recorded login flow stores the placeholder verbatim, so the committed YAML is secret-free — and agent-less `argent flow run` (#429) resolves it in CI from the job's env, no LLM in the loop at all. - The mandatory `ARGENT_SECRET_` prefix is an allowlist by construction: a prompt-injected agent can never exfiltrate `AWS_SECRET_ACCESS_KEY` or `GITHUB_TOKEN` through this mechanism — only vars the user deliberately exposed under the prefix resolve. - `typed` echoes the placeholder, never the value. - Backend errors are scrubbed at the resolution site (e.g. a failed Android `input text` echoes the device-side command line containing the secret) — message and stack, in place, preserving the error class and with it the HTTP-status/telemetry mapping. - Unknown placeholder → 400 listing the names of available secrets, never values (`SECRET_PLACEHOLDER_UNKNOWN`). - Auto-screenshot skip: the MCP layer deep-scans args for `{{secret:` and replaces the after-action screenshot with a text note — otherwise a non-secure-entry field hands the plaintext straight back to the model as an image. Covers nested `run-sequence` steps too. - Remote-routed setups resolve on the machine that types (the tool-server's env) — documented in the skill. - Inert unless a placeholder is used; no feature flag. ## Docs - `keyboard` / `paste` tool descriptions - `argent-device-interact` skill: "Typing secrets" section (incl. don't `describe`/`screenshot` the field you just filled — submit first) - `argent-create-flow` skill: never record a real credential; placeholder flows stay secret-free in the repo ## Known residual risks (shared with Stagehand-style designs) - A prompt-injected agent could direct `{{secret:X}}` into an attacker-visible field and screenshot it — inherent to any "agent types secrets" design; the prefix allowlist and no-read-back keep the blast radius to secrets deliberately exposed. - `describe` can read back a non-secure field's value after typing; iOS secure fields briefly show the last typed character; Android typing puts the resolved string on the device-side `input` command line. Acceptable for emulator CI; noted in the skill. - `keys` in the result still reflects the real keystroke count (secret length) — kept for debuggability. ## Tests - `keyboard-secrets.test.ts`: resolution (embedded/repeated placeholders, malformed shapes ignored), unknown-name error lists names but never values, redaction preserves error class, full `execute` round-trips on the chromium branch asserting the plaintext appears nowhere in results or thrown errors, paste via mocked `sendCommand`. - `auto-screenshot.test.ts`: `containsSecretPlaceholder` on flat/nested/unserializable args (fails safe). - Full suites green: tool-server 2550, argent-mcp 76, registry 87; builds + `typecheck:tests` + eslint + prettier clean. 🤖 Generated with [Claude Code](https://claude.com/claude-code)	2026-07-15 13:42:55 +02:00
