Soumya Medapati beeea625ab ci(security): harden docs-agent-eval caller (Bugbot fixes) (#4199) 
## Security fixes for the docs-agent-eval caller (Cursor Bugbot
findings)

Follow-up to #4158 (merged). Cursor Bugbot flagged two real issues on
the App-token caller; both fixed here. Two other findings were already
resolved in the merged version (noted below).

**Fixed:**
- **App token left on disk (Medium):** check out the private engine with
`persist-credentials: false`. Otherwise `actions/checkout` writes the
GitHub App installation token into `engine/.git/config`, and the eval
then runs untrusted agent code with filesystem access on the same runner
— which could read that token (read access to the private engine repo).
The token is only needed for the one-time fetch.
- **Non-docs previews start evals (Medium):** the `deployment_status`
trigger now requires the `environment_url` to start with `https://docs-`
(matching the label path's `docs-*` rule), so a non-docs
`*.preview.composio.dev` deployment can't start or cancel a docs eval.

**Already resolved in #4158 (stale Bugbot findings from the pre-App
design):**
- "Unrelated labels cancel evals" — the route job's `startsWith(…,
'run-docs-tests')` guard skips unrelated `labeled` events before
anything enters the eval concurrency group.
- "Eval token cannot read deployments" — `deployments: read` is set on
both jobs.

Informational check, non-blocking. No behavior change beyond the two
hardening fixes.

Soumya Medapati 55a17b992c ci: address Cursor Bugbot findings on the App-token caller 
- App token left on disk (Medium): checkout the private engine with
  persist-credentials: false, so the App installation token is never written
  to engine/.git/config where the eval's agent steps (filesystem access on the
  same runner) could read it. Token is only needed for the one-time fetch.
- Non-docs previews start evals (Medium): the deployment_status trigger now
  requires the environment_url to start with https://docs- (matching the
  label path's docs-* rule), so a non-docs *.preview.composio.dev deployment
  can't kick off or cancel a docs eval.

Already-resolved findings (stale, from the pre-App design): "unrelated labels
cancel evals" (route job's label guard skips unrelated labels before the
concurrency group) and "token cannot read deployments" (deployments: read is
set on both jobs).

Soumya Medapati c0b71a5dc5 ci: label-triggered docs agent eval (V1, informational) (#4158) 
## What this adds

A **label-triggered, non-blocking CI check** that tests whether a docs
PR's proposed content can still guide a fresh coding agent to working
Composio code — before merge, against the PR's own Vercel preview.

Add the **`run-docs-tests`** label to a docs PR →
1. A **route job** decides if and for which PR to run: label present +
PR author is an org member/collaborator. Two entry paths so either order
works — label added after the preview built (`pull_request` events), or
preview built after the label (`deployment_status` events, which also
cover new pushes; `synchronize` is deliberately not used).
2. A deterministic router classifies the change: **no-eval** (assets
only) / **Smoke** (1 agent) / **Deep** (5 agents — auth, install,
env-var, code-sample, endpoint, or navigation changes).
`run-docs-tests-deep` forces Deep.
3. The PR's exact-HEAD preview URL is resolved from **GitHub's
deployment records** (written by the Vercel↔GitHub integration, read
with the per-run `GITHUB_TOKEN`) — **no Vercel credentials anywhere**
(decision 2026-08-19). Isolated agents get it served through a rewrite
proxy — they believe they're on docs.composio.dev.
4. Each agent (fresh env, ephemeral Composio project, torn down after)
attempts the weather-toolkit task by following the docs.
5. An **independent judge** verdicts every run before teardown —
re-executes the agent's script with the run's live key and scans for the
v1 anti-patterns (hardcoded slugs, legacy packages, manual execution,
/examples cheating). The agent's own success claim is recorded but never
trusted; the PR comment shows L1·L2·L3 per run and any judge-overruled
self-reports.
6. Result lands here as a PR comment: **PASS / FAIL / ERROR**, run
counts, teardown status, and the agents' own docs-friction feedback. New
pushes supersede stale runs (`cancel-in-progress`).

**This file is a router + one SHA-pinned call** — all eval logic lives
in
[ComposioHQ/docs-agent-eval-ci](https://github.com/ComposioHQ/docs-agent-eval-ci)
(reusable workflow, SHA-pinned per org policy). See its
[ARCHITECTURE.md](https://github.com/ComposioHQ/docs-agent-eval-ci/blob/main/ARCHITECTURE.md)
for the full component map and design-spec compliance audit.

## Evidence it works (sandbox runs)

- End-to-end green Smoke, auto-routed:
[run](https://github.com/ComposioHQ/docs-agent-eval-ci/actions/runs/32056739696)
(PR #4125 → smoke → PASS 1/1)
- End-to-end green Deep, auto-routed:
[run](https://github.com/ComposioHQ/docs-agent-eval-ci/actions/runs/32057336110)
(PR #4136 → deep via auth-docs signal → PASS 5/5, incl. agent feedback
reproducing known docs findings)
- The exact `workflow_call` mechanism this shim uses:
[run](https://github.com/ComposioHQ/docs-agent-eval-ci/actions/runs/32059660256)
- Receipts-based preview resolution live-verified on PR #4174 (exact-SHA
→ snapshot URL); fork PRs (no Vercel build) correctly produce the
explained no-preview ERROR path
- Builder (DeepSeek V4 Flash) calibrated 16/16 against production docs
before any CI verdicts

## ⚠️ Before merge (repo admin)

1. ~~Secrets~~ **Done 2026-08-19**: `COMPOSIO_ORG_API_KEY` +
`DEEPSEEK_API_KEY` exist in this repo's Actions secrets. (`VERCEL_TOKEN`
is no longer needed — removed from the design.) Team-owned replacements
for the individually-owned keys remain part of the rollout (current
owner offboards Aug 31).
2. **Engine repo visibility**: `docs-agent-eval-ci` is currently
*internal*; a public repo cannot call an internal reusable workflow, so
it must be flipped public (pre-publication scrub done) **before** this
merges.
3. **Pin bump**: after the engine's `no-vercel-credentials` PR merges,
the `uses:` SHA here gets re-pinned to the engine's merge commit.

Labels `run-docs-tests` / `run-docs-tests-deep` are already created.

## Non-goals (V1)

Informational only — **do not mark this check required**. No merge
blocking, no statistical thresholds, no LLM routing; scenario is the
weather-toolkit eval only.

## Update 2026-08-21: keep the engine PRIVATE via a GitHub App

Design change (Sarah): the engine repo stays **private** instead of
going public. A public repo can't `uses:` a private repo's reusable
workflow, so the `eval` job now runs the engine **inline**:

1. mints a short-lived **GitHub App token**
(`actions/create-github-app-token`, SHA-pinned) scoped read-only to
`docs-agent-eval-ci`
2. checks the private engine out with it (`path: engine/`)
3. runs the engine on the runner (`route_pr.py` → `run_full_eval.py`);
result comment + check status still posted with composio's built-in
`GITHUB_TOKEN`

**⚠️ This supersedes the earlier public-reusable-workflow design in this
PR — needs a fresh review of the `eval` job.**

New repo secrets required (added): `DOCS_EVAL_APP_ID`,
`DOCS_EVAL_APP_PRIVATE_KEY`, plus existing `COMPOSIO_ORG_API_KEY`,
`DEEPSEEK_API_KEY`. No Vercel credentials.

Before this can be tested: the GitHub App must be **installed** on
ComposioHQ with **Contents: Read** on `docs-agent-eval-ci`. Since the
check only fires from the default branch, testing happens after this
merges (informational check, non-blocking, safe to merge to test).

Soumya Medapati ceeac2ed00 ci: run private engine via GitHub App token (replaces public reusable-workflow call) 
Keeps the engine repo private (Sarah 2026-08-21). A public repo can't
`uses:` a private repo's reusable workflow, so the eval job now:
  1. mints a short-lived GitHub App token (create-github-app-token, SHA-pinned)
  2. checks out the private engine repo with it (path: engine/)
  3. runs the engine inline (route_pr.py -> run_full_eval.py) on the runner
Result comment + check status still posted with the built-in GITHUB_TOKEN
(composio's own; App token is read-only on the engine repo).

Needs repo secrets: DOCS_EVAL_APP_ID, DOCS_EVAL_APP_PRIVATE_KEY (added),
plus existing COMPOSIO_ORG_API_KEY, DEEPSEEK_API_KEY.

shams haroon 38899bdfa0 fix: use Tool Router schemas for custom MCP search (#4185) 
## What this fixes

A custom MCP toolkit registered from the consumer dashboard could appear in the dashboard/Tool Router but not in `composio search`.

The CLI was receiving the custom toolkit from Tool Router search, then trying to fetch its schema through the legacy `/api/v3/tools/{slug}` endpoint. That endpoint does not serve dashboard-owned `CUSTOM_*` toolkits, so it returned 404 and the CLI could not complete the search result.

## How it fixes it

- For remote `CUSTOM_*` toolkit slugs with an inline `input_schema`, the CLI uses the schema already returned by Tool Router search.
- For `CUSTOM_*` results that contain only a `schemaRef`, the CLI calls Tool Router's `COMPOSIO_GET_TOOL_SCHEMAS` meta-tool in the same session and uses the returned schema.
- Both paths store the schema through the existing local tool-definition cache path, so normal execution can use it.
- Managed Composio toolkits keep the existing schema-fetch path.
- Existing cache behavior is unchanged.

## Reproduction

We reproduced this against a production dashboard-created DeepWiki custom MCP:

- Before the fix, a cold-cache CLI search reached the custom toolkit but failed on the legacy schema lookup with 404.
- With the fix, unfiltered `composio search` returned the custom MCP tools.
- Executing the returned custom tool succeeded and returned the DeepWiki response.
- Regression coverage also verifies the schema-reference path does not use the legacy endpoint.

## Scope

This fixes the `composio search` → normal execute path for dashboard-created custom MCP toolkits.

This PR does not change:

- CLI cache TTLs or refresh behavior
- Dashboard-to-CLI cache invalidation
- The separate schema paths used by `composio tools info` or `composio execute --dry-run`

## Validation

- Focused CLI tests: 21 passed
- Full CLI test suite: 1,256 passed, 1 skipped
- Source and test typechecks passed
- Focused Oxlint passed
- Production reproduction passed

Alberto Schiabel 5e7432372a fix(cli): ship every codex-acp binary in release archives (#4186) 
## Problem

`composio upgrade` fails on every CLI currently in the field, including
stable `0.3.3`:

```
💥  services/UpgradeBinaryError  • Downloaded binary package is incomplete
Caused by: Missing companion module: …/extract/composio-darwin-aarch64/acp-adapters/codex/darwin-x64/codex-acp
```

`archiveCompanionRelativePaths` (added 2026-08-18 in #4134) narrows each
release archive to the shared ACP assets plus only the one `codex-acp`
its platform can execute. That is a sound optimisation, but it shipped
writer-first: a CLI released *before* it verifies a downloaded package
against `RUN_COMPANION_STATIC_ASSET_RELATIVE_PATHS` — shared assets plus
**all four** codex target paths — with no parameter to relax the check,
and hard-fails on any archive missing one.

Stable `0.3.3` shipped 2026-08-11, a week before that change, so the
entire installed stable base is affected. Recovery today means
re-running `install.sh` by hand.

Evidence:

| Archive | codex binaries shipped |
| --- | --- |
| `0.3.4-beta.351` (pre-#4134) | `darwin-arm64`, `darwin-x64`,
`linux-arm64`, `linux-x64` |
| `0.4.0-beta.357` (post-#4134) | `darwin-arm64` only |

## Fix

The reader has to become tolerant before the writer narrows, and the
already-installed reader cannot be patched retroactively. Packaging
ships the full companion set again.

`archiveCompanionRelativePaths` stays in place with its tests,
documented as deliberately uncalled. Re-wiring it into
`package-binaries.ts` is a one-line change once no supported client
still validates all four paths — worth roughly 651 MB per archive.

## Why CI missed it

`cli.test-installation.yml` only exercises fresh `install.sh` installs,
which are unaffected: each archive is internally consistent. Nothing
covers an in-place upgrade from a previously released binary. Worth
closing separately — it needs a real prior-stable binary in the matrix,
not a unit test.

## Verification

- `vitest run test/src/scripts/release-artifacts.test.ts` — 29 passed
- `pnpm --filter @composio/cli typecheck` — clean
- `pnpm validate:changesets` — passes (CLI is Changesets-ignored; note
lands in `ts/packages/cli/CHANGELOG.md`)
- Added coverage asserting every release artifact's codex-acp binary is
in the packaged set
- Final check is the archive itself: the beta cut from this branch must
contain all four `acp-adapters/codex/*/codex-acp` entries, and `composio
upgrade` must succeed from a pre-#4134 install

`@composio/cli@0.4.0-beta.357` should be abandoned rather than promoted.

Alberto Schiabel 64406ff359 chore(cli): bump Bun to 1.4.0 and replace tar with Bun.Archive (#4183) 
Bumps the mise-pinned Bun toolchain from 1.3.10 to 1.4.0 and replaces
the one CLI dependency that a Bun 1.4 built-in can verifiably take over.

## Binary size: Linux shrinks a lot, macOS grows a little

Measured per target, byte counts from `build:binary:all` on a
darwin-arm64 host.

| Target | Before (1.3.10) | After runtime (1.4.0) | After full | Δ
total | Δ % |
|---|---:|---:|---:|---:|---:|
| `composio-darwin-aarch64` | 80,850,704 (77.1 MiB) | 83,790,962 (79.9
MiB) | 83,790,962 (79.9 MiB) | +2,940,258 (+2.8 MiB) | +3.6% |
| `composio-darwin-x64` | 85,710,240 (81.7 MiB) | 90,430,880 (86.2 MiB)
| 90,430,880 (86.2 MiB) | +4,720,640 (+4.5 MiB) | +5.5% |
| `composio-linux-x64` | 123,666,298 (117.9 MiB) | 102,270,152 (97.5
MiB) | 102,270,152 (97.5 MiB) | -21,396,146 (-20.4 MiB) | -17.3% |
| `composio-linux-aarch64` | 121,153,270 (115.5 MiB) | 102,221,816 (97.5
MiB) | 102,221,816 (97.5 MiB) | -18,931,454 (-18.1 MiB) | -15.6% |

**Attribution — read this before quoting the numbers.** Every byte of
movement above comes from the **Bun runtime bump**, not from dependency
removal. The "after runtime" and "after full" columns are
byte-identical: the only dependency dropped here is `tar`, a
devDependency used by one build script that never reaches the binary.
Its size contribution is exactly **0 bytes**. (The identical columns
also confirm the compiled build is reproducible across runs.)

Linux users — the large majority of installs — get a ~18-20 MiB smaller
binary. macOS grows 2.8-4.5 MiB. This matches the direction upstream
reports for the standalone Bun binary.

## What changed

- `mise.toml` pins `bun = "1.4.0"`; `mise.lock` regenerated with the
exact platform list `ts.audit` uses.
- `scripts/_acp-adapters.ts` extracts npm tarballs with `Bun.Archive`
instead of the `tar` package.
- `tar` dropped from `@composio/cli` devDependencies (plus
`@isaacs/fs-minipass`, `chownr`, `minizlib`, `yallist` from the
lockfile).

## Verified negative results

These are the two adjacent candidates a reviewer would expect to see
replaced. Both were probed against a real Bun 1.4.0 binary and both fail
— recorded here so nobody re-derives the dead ends:

- **`extract-zip` stays.** `Bun.Archive` cannot read zip: `new
Bun.Archive(zipBytes)` throws `Unrecognized archive format`, and
`ArchiveOptions.compress` accepts only `"gzip"`. Still used at three
call sites.
- **`semver` stays.** `Object.keys(Bun.semver)` returns exactly
`["satisfies", "order"]`. The CLI also needs `valid`, `prerelease`,
`compare`, `gt`, and `lt`. `valid` and `prerelease` have no equivalent,
so a partial migration would only add a second semver dialect.

## `json5` → `Bun.JSON5` was attempted and backed out

`parse-json.ts` is covered by the CLI's Vitest suite, which runs on
**Node**, where the `Bun` global does not exist — `Bun.JSON5.parse`
throws `ReferenceError` under test. The suite cannot move to the Bun
runtime (88 of 122 files fail there on unrelated zod resolution errors),
and `bun test` for a single file would conflict with the repo's
`@effect/vitest` lint rule.

The swap itself is sound — `Bun.JSON5.parse` matched the `json5` package
on all nine contract cases against a real 1.4.0 binary, including
`SyntaxError` on malformed input. It is the test harness, not the
parser, that blocks it. Deferred rather than shipped with weakened
coverage.

For sizing the follow-up: `--metafile-md` puts `json5` at **28,045 bytes
(0.1%)** of the JS bundle, imported only by `src/utils/parse-json.ts` —
roughly 0.03% of a compiled binary. Worth doing for dependency-surface
reasons, not for size.

## Verification

- All four release targets cross-compile on Bun 1.4.0.
- `mise lock --platform linux-x64,linux-arm64,macos-arm64,macos-x64`
then `git diff --exit-code mise.lock` is clean, replayed in a CI-like
environment.
- `pnpm typecheck` clean; CLI suite green (122 files, 1248 passed, 1
skipped).
- `Bun.Archive` adapter build against the live npm registry produces
codex-acp binaries **byte-identical** (SHA-256) to the `tar`-produced
ones, at the same `package/bin/<name>` paths, executable after `chmod`,
extracted concurrently. A truncated tarball throws `ReadError` rather
than silently yielding an empty directory.
- Runtime smoke on the 1.4.0 binary: `composio version`, `composio
--help`, and the `composio run` companion-module spawn path (reports
`process.version` v26.3.0 — no Node 26 stream regression). `extract-zip`
verified working under the new runtime.

### Not run locally

`pnpm test:e2e:cli` needs Docker, which was unavailable on this machine.
CI covers it. Worth a look at that job: the e2e image is version-keyed
and has served a stale Bun binary from a cached layer before, so confirm
the container reports 1.4.0.

## Notes

- `@types/bun` is deliberately not bumped: `Bun.JSON5` and `Bun.Archive`
are already declared in the installed `bun-types@1.3.14`, no
`@types/bun` 1.4.x exists yet, and `minimumReleaseAge` would block a
fresh pin anyway.
- No changeset: `@composio/cli` is in `.changeset/config.json`'s
`ignore` list and no published package is touched.
- `mise lock` locally adds a stray `[[tools.node]] 24.19.0` block
sourced from the developer's global mise config. It was stripped; the
committed lock is stable under the audit gate's exact command.

Alberto Schiabel d544006a25 fix(sdk): pin the validated address when fetching URLs (SSRF DNS rebinding) (#4172) 
Fixes #4151.

## The problem

Both SDKs validated a URL by resolving its hostname, and then handed the
*hostname* to the HTTP client, which resolved it again when it opened
the socket. Two lookups, two answers: a short-TTL record under an
attacker's control answers publicly for the check and with
`169.254.169.254`, `127.0.0.1`, or RFC 1918 space for the connect. The
guard passes and the connection lands inside the network — classic
TOCTOU DNS rebinding, documented in both modules until now as a known
residual.

```mermaid
sequenceDiagram
    participant SDK
    participant DNS as Attacker DNS
    participant Meta as 169.254.169.254
    Note over SDK,Meta: before
    SDK->>DNS: resolve evil.example.com (validate)
    DNS-->>SDK: 93.184.216.34 — passes the guard
    SDK->>DNS: resolve evil.example.com (connect)
    DNS-->>SDK: 169.254.169.254
    SDK->>Meta: GET /latest/meta-data/…
    Meta-->>SDK: credentials
```

## The fix

Resolve once, validate every answer, then connect to the address that
was validated. There is no second lookup left to rebind.

- **Python** — `safe_get` / `safe_request` mount a transport adapter
that swaps the connect target for the duration of the socket connect
only. The `Host` header and TLS SNI keep the hostname, so certificate
verification is unchanged; rewriting `conn._dns_host` for the whole
connection would have sent `Host: <ip>` and offered the IP as SNI,
failing against every real origin. Every fetch call site now goes
through those two helpers, so no `requests.get` sits next to a bare
check any more:
- `_files.py::_fetch_file_from_url`,
`_files.py::FileDownloadable.download`
  - `tool_router_session_files.py::_fetch_url_bytes`
  - `safe_request`, per redirect hop
- **TypeScript** — `assertSafeFetchTarget` returns the validated address
and `ssrfSafeFetch` hands `fetch` a dispatcher pinned to it, re-pinned
per redirect hop. The dispatcher goes to the runtime's own `fetch`, so
callers that stub `globalThis.fetch` keep working. The pinned `lookup`
answers both shapes Node calls it with — the address *list* it uses for
Happy Eyeballs, and the single `(address, family)` it uses when
`autoSelectFamily` is off — since answering in the wrong shape is
rejected as an invalid address.
- A fail-closed peer assertion runs on the Python side before a byte is
written to the socket — redundant while pinning works, and a tripwire if
a urllib3 upgrade ever breaks it.
- `workerd` is unchanged: it already fails closed for user-supplied
URLs.

Redirect *validation* already existed in both SDKs (`safe_request` /
`ssrfSafeFetch`); what was missing was re-pinning each hop.

## Tests

The existing suites could not express this bug: they mock both the
resolver and the HTTP client, so check and use are the same mock. The
new tests use real sockets.

- `python/tests/test_url_safety_pinning.py` — two loopback servers and a
resolver that answers the first lookup with one endpoint and every later
one with another, which is what a short-TTL rebinding record does.
Asserts the rebound endpoint receives **zero** connections, and that
`Host` still carries the hostname. Both tests fail on `next` and pass
here.
- `ts/packages/core/test/utils/pinnedDispatcher.node.test.ts` — a real
server plus a hostname under `.invalid`, which RFC 2606 guarantees never
resolves. A request that arrives proves the connect used the pinned
address and never consulted DNS. The third case shows the contrast:
unpinned, the same fetch cannot resolve at all.
- `ssrfGuard.test.ts` gains assertions that each hop is pinned to that
hop's own validated address.
- `pinnedDispatcher.node.test.ts` also pins with
`setDefaultAutoSelectFamily(false)`, which is the branch Node takes for
the single-address callback.

## Notes

- Supersedes #4157, which diagnosed this correctly. Its post-response
peer check turned out not to hold: with an HTTP/1.0 or `Connection:
close` server, urllib3 detaches the socket (`conn.sock is None`) while
`r.content` still returns the full body, so the check fails open exactly
where exfiltration succeeds. That is why the assertion here runs at
connect time instead.
- The Python package now declares `urllib3>=2` directly. `url_safety`
imports it for `NameResolutionError`, which only exists from 2.0, and
the pinning adapter reaches into 2.x connection internals; `requests`
alone allows 1.x, where `import composio` would have failed outright.
- `@composio/core` gains an `undici` dependency, pinned to `^7`: undici
8 dispatchers are rejected by the `fetch` in every Node version this
package supports (22/24/25, verified). The real-socket test runs on the
full CI matrix, so a future incompatibility fails loudly instead of
silently un-pinning.
- `undici` is imported on first pinned request rather than at module
load: importing it installs a process-wide global dispatcher, which
would have handed the host application's own unrelated `fetch` calls
this package's undici merely because it imported `@composio/core`.
- Residuals, now documented in the modules:
- Requests routed through an environment proxy keep the pre-flight check
only. The proxy resolves the hostname itself and the SDK cannot see or
pin that resolution.
- A process that does perform a pinned fetch still ends up on this
package's `Agent` if nothing had claimed the global dispatcher slot yet.
undici defines that slot non-configurable, so it cannot be handed back —
assigning `undefined` leaves the runtime's own `fetch` asserting on a
missing dispatcher.

Sarah Simionescu 77eb7d45b9 docs(white-labeling): document the Connect Link theme editor (PRDE-1196) (#4175) 
## What

The **White Labeling** settings (Project Settings → White Labeling, at
`/settings/auth-screen`) now ship a full **theme editor** for the hosted
Connect Link page: seed colours, typefaces, geometry, and per-element
styling, with a live preview across the Welcome/Form/Success/Error
states, a JSON mode, and a server-enforced contrast floor. Both
white-labeling guides only covered logo + app title, so this updates
them.

## Changes

- **`authentication/white-labeling-authentication.mdx`** (current,
sessions) and **`auth-configuration/white-labeling.mdx`** (legacy,
direct execution) — split "Customizing the Connect Link" into:
  - **Logo and name** (Branding tab)
  - **Colors, fonts, and per-element styling** (Styling tab)
- Aligned terminology to the shipped UI: **White Labeling** nav item,
**Branding**/**Styling** tabs, **Typefaces**, **JSON** toggle, **Save
Changes**, and the enforced-contrast note.
- Added `auth-screen-theme-editor.png`; removed the now-stale
branding-only `connect-link-branding.mp4`.
- The legacy page keeps all its direct-execution content (`initiate()`,
`long_redirect_url`) untouched.

## Notes

- The theme editor is gated behind the `link-auth-theming` flag, so the
docs include a troubleshooting line for projects where the Styling tab
hasn't rolled out yet.
- The screenshot currently shows the Branding tab in its default state;
it can be swapped for a Styling-tab shot with a custom theme over the
same filename later.

Alberto Schiabel 9fe68b96f0 docs(providers): resolve session-aware helper pins to published versions (#4171) 
Follow-up to #4170 / #4161, deferred until npm publish landed (per
#4098's own follow-up note).

- bumps `docs/package.json` pins: `@composio/core` `^0.15.0` ->
`^0.17.0`, `@composio/anthropic` `^0.10.1` -> `^0.11.0`,
`@composio/openai` `^0.11.0` -> `^0.12.0` — all three are now live on
npm
- removes the `@errors: 2345` Twoslash suppression markers (and their
TODO comments) in the OpenAI and Anthropic provider docs, now that the
session-aware `handleToolCalls`/`executeToolCall` overloads type-check
against the resolved package versions
- regenerates `docs/bun.lock`

## Verification

- `bun install` resolves `@composio/core@0.17.0`,
`@composio/anthropic@0.11.0`, `@composio/openai@0.12.0`
- `bun run types:check` passes
- `bun run build` passes, including Twoslash compilation of the updated
code samples with the suppression markers removed

# Releases
## @composio/core@0.17.0

### Minor Changes

- 760f8d0: Allow OpenAI and Anthropic provider tool-call helpers to
execute through a supplied Tool Router session. Session meta-tools now
retain their session context while provider argument normalization
remains intact; existing user-ID calls continue to use direct execution.
Anthropic helper failures now preserve their error text in `{ error }`
results without changing successful payloads. Custom provider subclasses
overriding `executeToolCall` or `handleToolCalls` may require updates
because these methods now accept session targets.

### Patch Changes

- 6ba9179: Validate the URLs that come from API responses before
fetching them. Tool-execution downloads (`s3Url`), S3 presigned uploads
(`new_presigned_url`), Tool Router session file downloads
(`RemoteFile.buffer()` / `blob()` / `text()` / `save()`) and session
file uploads (`upload_url`) now go through the same SSRF guard that
already covered user-supplied URLs, so a response naming a private,
loopback, or link-local address is refused instead of fetched. Redirect
hops are re-validated. Edge runtimes keep their current behavior:
session file transfers are not blocked there, since a Worker cannot
resolve DNS to check and its `fetch` does not originate inside the
caller's network.

Alberto Schiabel e3534e7ea6 chore(sdk): prepare Python 0.20.0 and TypeScript 0.17.0 releases (#4170) 
This PR:

- bumps `composio` and all 13 provider distributions from `0.19.0` to
`0.20.0`, keeping `python/composio/__version__.py` and `uv.lock` aligned
with package metadata
- adds `docs/content/changelog/08-19-26-sdk-releases.mdx`, the combined
customer-facing changelog for both SDKs, documenting the session-aware
provider tool-call helpers from #4098 (Python `composio` 0.20.0,
TypeScript `@composio/core`/`@composio/slim` 0.17.0,
`@composio/anthropic` 0.11.0, `@composio/openai` 0.12.0) and the
API-response URL validation and Python file-handling fixes shipped since
the last train
- documents `@composio/core` `0.17.0` in that entry so the generated
Changesets release PR (#4161) passes the release-workflow guard

## Release sequence

1. Merge this PR.
2. Merge #4161 (the generated "Release: update version" PR) once it goes
green. Merging publishes the TypeScript packages to npm.
3. Tag the resulting `next` commit `py@0.20.0` to publish the Python
packages to PyPI.
4. Follow-up PR: bump `docs/package.json` pins to
`@composio/core@^0.17.0`, `@composio/anthropic@^0.11.0`,
`@composio/openai@^0.12.0` and remove the now-stale `@errors: 2345`
Twoslash TODO markers in the provider docs, once the npm publish lands.

## Verification

- Verified the release-workflow guard reads the new changelog rows for
Python `0.20.0` and TypeScript `@composio/core` `0.17.0`
- All 13 Python `pyproject.toml`/`setup.py` pairs bumped consistently;
`uv.lock` regenerated

Soumya Medapati 760f8d0367 fix(sdk): route provider tool calls through sessions (#4098) 
## Problem

Provider tool-call helpers always used the globally injected direct
`Tools.execute` function. When a model received tools from
`session.tools()`, calling `handleToolCalls` or `handle_tool_calls`
therefore discarded the Tool Router session context and caused session
meta-tools such as `COMPOSIO_SEARCH_TOOLS` to fail.

Calling `session.execute()` manually preserved the session, but bypassed
provider behavior such as Anthropic input normalization and schema-alias
restoration.

## Root fix

- Add an explicit execution target to the non-agentic provider helpers:
- TypeScript: `handleToolCalls(session, response)` and
`executeToolCall(session, call)`
- Python: `handle_tool_calls(response=response, session=session)` and
`execute_tool_call(tool_call=call, session=session)`
- Route normalized provider arguments through the supplied Tool Router
session.
- Map session responses back to each helper's existing result shape.
- Keep provider-specific normalization before execution, including
Anthropic schema-alias restoration.
- Reject direct-only options and modifiers when the selected target is a
session, including plain JavaScript calls that bypass the TypeScript
overloads.
- Update OpenAI and Anthropic examples to use the session-aware helpers.
- Harden the docs policy test so setup and execution split across fences
in one sample are still detected.

## Docs review follow-ups

- Reword the concepts-page prohibition so it forbids user-ID-bound
helper calls, not the helpers themselves, matching the provider pages in
this PR.
- Add minimum-version callouts to the OpenAI and Anthropic provider
pages (Python `composio` newer than 0.19.0; TypeScript `@composio/core`
≥ 0.17.0 with `@composio/openai` ≥ 0.12.0 / `@composio/anthropic` ≥
0.11.0), pointing older versions at `session.execute()`.
- Bump `docs/package.json` to `@composio/core` `^0.15.0` and
`@composio/openai` `^0.11.0` (the published majors at the time of the
bump; `@composio/core` 0.16.0 and `composio` 0.19.0 have since released
from `next` without this PR, so its changeset will publish core 0.17.0
and the next Python minor) and annotate each `@errors: 2345` Twoslash
marker with a TODO naming the minor version that retires it; since this
changeset releases minors, all three pins need a manual range bump to
retire the markers. This version of twoslash only throws on *unlisted*
errors, so a stale marker cannot break the build — it would only mask
future TS2345s, which the TODOs now track.
- Update `SESSION_GUARDRAILS` (the block appended to `.md` responses for
agents): add a session-execution bullet (scoped to the OpenAI and
Anthropic helpers, with `session.execute()` for every other provider)
and qualify the direct-execution list with "with a user ID". The
session-execution static test now scans the guardrail blocks like the
execute-version test already did.
- Tighten the docs detector: the Python branch is bounded to the helper
call's argument list (tolerating one level of nested calls) instead of
running past the closing paren, and the TypeScript branch catches whole
user-ID identifiers (`userId`, `user_id`, `uid`) without flagging
session variables like `userSession` — each edge has a regression test.
- Note on the Google provider page that its `executeToolCall` is not
session-aware yet.

## Compatibility and release

Existing user-ID calls remain unchanged and continue to use direct tool
execution. The new session call forms are additive.

The changeset applies minor releases to `@composio/core`,
`@composio/openai`, and `@composio/anthropic` — the new session
overloads are a type-level break for provider subclasses, so patch was
too small. The configured fixed group also includes `@composio/slim`.

The docs site intentionally checks examples against currently published
SDK declarations. The three new TypeScript calls therefore carry exact
Twoslash `TS2345` release-skew annotations; remove them (per the inline
TODOs) once `docs/package.json` picks up `@composio/core` ≥ 0.17.0,
`@composio/openai` ≥ 0.12.0, and `@composio/anthropic` ≥ 0.11.0.

## Verification

- `@composio/core`: 1,061 tests passed; typecheck passed
- `@composio/openai`: 34 tests passed; typecheck passed
- `@composio/anthropic`: 53 tests passed; typecheck passed
- Python provider and aliasing suites: 40 passed, 4 skipped
- Focused Python mypy and Ruff checks passed
- Docs static suite: 208 tests passed (including the new guardrail-scan
and detector cases)
- Docs production build passed with the bumped `@composio/core` 0.15.0 /
`@composio/openai` 0.11.0, including Twoslash, TypeScript, and all
generated pages
- Docs lint passed; lint reports only existing warnings
- Changeset status reports the expected minor packages

Alberto Schiabel b1c6671b20 fix(py): send Content-Type on S3 PUTs and parse Content-Length (#4168) 
This PR:
- fixes #4153
- supersedes https://github.com/ComposioHQ/composio/pull/4154 (fork PR
authored against a pre-#4146 tree; its tests patch `requests.put`, which
`upload()` no longer calls after #4146, so they fail on merge)
- adds `parse_content_length()` in `composio.utils.url_safety`, shared
by both URL fetch helpers (`_files.py::_fetch_file_from_url` and
`tool_router_session_files.py::_fetch_url_bytes`), so a
malformed/negative remote `Content-Length` degrades to unknown size
under the streamed byte count instead of raising a raw `ValueError`
- converges the file and bytes upload paths onto
`_upload_to_presigned_url()`: one PUT that sends the `Content-Type` the
presign request was signed with and raises `ErrorUploadingFile` carrying
the HTTP status (a 403 no longer collapses into a path-only error)
- single-sources the presign wire shape via
`_request_presigned_upload()`; `from_path()` forwards the exact mimetype
it minted, so signed and sent content types cannot drift
- mirrors the TypeScript SDK: `uploadFileToS3` funnels path/URL/File
inputs through one uploader that always sends `Content-Type` and throws
on non-2xx, and `readResponseBodyWithLimit` trusts `Content-Length` only
as a hint
- adds tests against the `safe_request` seam
(`test_file_upload_robustness.py`, plus one malformed-header case for
`RemoteFile.buffer()`)

## Context

Both defects in #4153 were symptoms of two parallel upload paths
drifting: the bytes path sent `Content-Type` and raised with the status,
the file path did neither. Patching the symptom in place (as #4154
proposed) would have left three presigned PUT sites and two error
contracts in the tree; this PR deletes the drift vector instead. Full
suite green (1320 passed), `make chk` and `make snt` clean; Python-only
change, so no changeset per `AGENTS.md`.

Updates `@mastra/mcp` from 1.15.0 to 1.16.0
<details>
<summary>Release notes</summary>
<p><em>Sourced from <a
href="https://github.com/mastra-ai/mastra/releases">@​mastra/mcp's
releases</a>.</em></p>
<blockquote>
<h2>Mar 25, 2026</h2>
<h2>Highlights</h2>
<h3>Smarter Model Selection for Observational Memory</h3>
<p><code>@mastra/memory</code> now lets you route observer and reflector
calls to different models based on input size using
<code>ModelByInputTokens</code>. Short inputs can go to a fast, cheap
model while longer ones get sent to a more capable one -- all configured
declaratively with token thresholds. Tracing shows which model was
selected and why.</p>
<h3>MongoDB Support for Datasets and Experiments</h3>
<p><code>@mastra/mongodb</code> now stores versioned datasets with full
item history and time-travel queries, plus experiment results and CRUD.
If you're already using <code>MongoDBStore</code>, this works
automatically with no extra setup.</p>
<h3>Okta Auth and RBAC</h3>
<p>New <code>@mastra/auth-okta</code> package brings SSO authentication
and role-based access control via Okta. Map Okta groups to Mastra
permissions, verify JWTs against Okta's JWKS endpoint, and manage
sessions -- or pair Okta RBAC with a different auth provider like Auth0
or Clerk.</p>
<h3>Breaking Changes</h3>

<h4>Minor Changes</h4>
<ul>
<li>
<p>Added dataset-agent association and experiment status tracking for
the Evaluate workflow. (<a
href="https://redirect.github.com/mastra-ai/mastra/pull/14470">#14470</a>)</p>
<ul>
<li><strong>Dataset targeting</strong>: Added <code>targetType</code>
and <code>targetIds</code> fields to datasets, enabling association with
agents, scorers, or workflows. Datasets can now be linked to multiple
entities.</li>
<li><strong>Experiment status</strong>: Added <code>status</code> field
to experiment results (<code>'needs-review'</code>,
<code>'reviewed'</code>, <code>'complete'</code>) for review queue
workflow.</li>
<li><strong>Dataset experiment routes</strong>: Added API endpoints for
triggering experiments from a dataset with configurable target type and
target ID.</li>
<li><strong>LLM data generation</strong>: Added endpoint for generating
dataset items using an LLM with configurable count and prompt.</li>
<li><strong>Failure analysis</strong>: Added endpoint for clustering
experiment failures and proposing tags using LLM analysis.</li>
</ul>
</li>
<li>
<p>Added agent version support for experiments. When triggering an
experiment, you can now pass an <code>agentVersion</code> parameter to
pin which agent version to use. The agent version is stored with the
experiment and returned in experiment responses. (<a
href="https://redirect.github.com/mastra-ai/mastra/pull/14562">#14562</a>)</p>
<pre lang="ts"><code>const client = new MastraClient();
<p>await client.triggerDatasetExperiment({
datasetId: &quot;my-dataset&quot;,
targetType: &quot;agent&quot;,
targetId: &quot;my-agent&quot;,
version: 3, // pin to dataset version 3
agentVersion: &quot;ver_abc123&quot; // pin to a specific agent version
});
</code></pre></p>
</li>
<li>
<p>Added tool suspension handling to the Harness. (<a
href="https://redirect.github.com/mastra-ai/mastra/pull/14611">#14611</a>)</p>
<p>When a tool calls <code>suspend()</code> during execution, the
harness now emits a <code>tool_suspended</code> event, reports
<code>agent_end</code> with reason <code>'suspended'</code>, and exposes
<code>respondToToolSuspension()</code> to resume execution with
user-provided data.</p>
</li>

<blockquote>
<h2>1.16.0</h2>
<h3>Minor Changes</h3>
<ul>
<li>
<p>Updated the MCP client and server to run on the MCP 2.0 packages.
Request context, authentication, logging, and progress behavior are
unchanged, so tools that read <code>context.mcp.extra.authInfo</code>,
send progress, or use elicitation keep working as before. (<a
href="https://redirect.github.com/mastra-ai/mastra/pull/18683">#18683</a>)</p>
<p>Tool schemas advertised over MCP no longer declare a draft-07
<code>$schema</code> dialect. The MCP 2.0 default validator rejects that
dialect, which previously made tools with output schemas fail on the
client.</p>
<p><strong>If you pass a custom schema validator</strong></p>
<p>The optional <code>jsonSchemaValidator</code> option now takes its
validator from the MCP packages. Update the import path:</p>
<pre lang="ts"><code>// Before
import { CfWorkerJsonSchemaValidator } from
'@modelcontextprotocol/sdk/validation/cfworker';
<p>// After
import { CfWorkerJsonSchemaValidator } from
'<code>@​modelcontextprotocol/client/</code>validators/cf-worker';</p>
<p>const mcp = new MCPClient({
servers: {
weather: { url: new URL('<a
href="https://example.com/mcp">https://example.com/mcp</a>'),
jsonSchemaValidator: new CfWorkerJsonSchemaValidator() },
},
});
</code></pre></p>
<p><strong>If you import MCP protocol types directly</strong></p>
<p>Types re-exported by <code>@mastra/mcp</code> (such as
<code>ToolAnnotations</code>, <code>LoggingLevel</code>, and the OAuth
helpers) are unchanged and need no edits. Only imports that reached past
<code>@mastra/mcp</code> into <code>@modelcontextprotocol/sdk</code>
need repointing to <code>@modelcontextprotocol/client</code> or
<code>@modelcontextprotocol/server</code>.</p>
</li>
<li>
<p>Add opt-in security hardening options to the MCP client. Both options
are opt-in; default behavior is unchanged. (<a
href="https://redirect.github.com/mastra-ai/mastra/pull/20868">#20868</a>)</p>
<ul>
<li><code>allowedHosts</code> on HTTP server configs restricts which
hosts the client's HTTP requests may target, covering the initial
connection, the SSE fallback, and OAuth discovery. On the default fetch
path redirect hops are blocked before they are sent; with a custom
<code>fetch</code>, the final response URL is validated after the
request runs, so custom fetch implementations must enforce redirect
policy themselves when preventing outbound contact is required.</li>
<li><code>inheritDefaultEnv: false</code> on stdio server configs stops
the subprocess from inheriting the SDK's default environment variables;
only the entries you list in <code>env</code> are passed.</li>
</ul>
<pre lang="typescript"><code>const mcp = new MCPClient({
  servers: {
    weather: {
      url: new URL('https://weather.example/mcp'),
      allowedHosts: ['weather.example'],
    },
    local: {
      command: 'npx',
      args: ['tsx', 'stdio-server.ts'],
      inheritDefaultEnv: false,
      env: { WEATHER_API_KEY: process.env.WEATHER_API_KEY! },
    },
  },
});

- feat(core): mark errors as retryable or not, and stop retrying the
ones that aren't</p>
<p>Retry middleware retried every failure up to <code>maxRetries</code>,
including deterministic ones like a bad API key or an unknown model.
Retries also nest, so a single such failure could cost dozens of API
calls.</p>
<p><code>@langchain/core/errors</code> adds <code>stampRetryable(error,
retryable)</code> and <code>getRetryable(error)</code>. Marking an error
leaves its class and shape untouched, so a provider SDK error can be
classified without breaking <code>instanceof</code>.
<code>getRetryable</code> returns <code>undefined</code> for errors
nobody classified, and both are exported so tool authors can mark their
own failures.</p>
<p><code>modelRetryMiddleware</code> and
<code>toolRetryMiddleware</code> now respect the mark by default, and
retries stop as soon as one is found rather than each layer spending its
own budget. Aborted calls, context overflow, and oversized payloads are
marked non-retryable out of the box.
Models accept a per-call <code>maxRetries</code> so a surrounding retry
loop can take over.</p>
<p><strong>Behavior change:</strong> errors marked non-retryable now
fail on the first attempt. Unclassified errors — including any from
third-party integrations or custom tools — retry exactly as before. Pass
<code>retryOn: () =&gt; true</code> to restore the old default. A custom
<code>onFailedAttempt</code> replaces the built-in handler and opts out
of marking.</p>

fix: apply [Symbol.hasInstance] method to all comparable properties
using .isInstance()</p>
<p>We have some internal schemas that rely on
<code>z.instanceof()</code>. This uses a strict <code>instanceof</code>
check which can conflict if there are multiple versions of core
installed. This overrides the <a
href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol/hasInstance">Symbol.hasInstance</a>
method to use the same logic as <code>.isInstance()</code> to compare
objects at runtime.</p>

- feat(openai): mark OpenAI provider errors as retryable or not</p>
<p>Builds on <code>stampRetryable</code> in <code>@langchain/core</code>
so the retry middleware can tell a transient failure from a
deterministic one. Timeouts and rate limits are marked retryable;
aborts, context overflow, invalid tool results, bad credentials, and
unknown models non-retryable. Anything else stays unmarked and retries
as before.</p>
<p>Also forwards a per-call <code>maxRetries</code> to the retry loop,
so a surrounding retry loop such as <code>modelRetryMiddleware</code>
can take over instead of the two multiplying against each other.</p>
<p>Errors keep their original class, so <code>instanceof</code> against
the <code>openai</code> SDK error types is unaffected.</p>

- feat(core): mark errors as retryable or not, and stop retrying the
ones that aren't</p>
<p>Retry middleware retried every failure up to <code>maxRetries</code>,
including deterministic ones like a bad API key or an unknown model.
Retries also nest, so a single such failure could cost dozens of API
calls.</p>
<p><code>@langchain/core/errors</code> adds <code>stampRetryable(error,
retryable)</code> and <code>getRetryable(error)</code>. Marking an error
leaves its class and shape untouched, so a provider SDK error can be
classified without breaking <code>instanceof</code>.
<code>getRetryable</code> returns <code>undefined</code> for errors
nobody classified, and both are exported so tool authors can mark their
own failures.</p>
<p><code>modelRetryMiddleware</code> and
<code>toolRetryMiddleware</code> now respect the mark by default, and
retries stop as soon as one is found rather than each layer spending its
own budget. Aborted calls, context overflow, and oversized payloads are
marked non-retryable out of the box.
Models accept a per-call <code>maxRetries</code> so a surrounding retry
loop can take over.</p>
<p><strong>Behavior change:</strong> errors marked non-retryable now
fail on the first attempt. Unclassified errors — including any from
third-party integrations or custom tools — retry exactly as before. Pass
<code>retryOn: () =&gt; true</code> to restore the old default. A custom
<code>onFailedAttempt</code> replaces the built-in handler and opts out
of marking.</p>

Alberto Schiabel 6ba9179b48 fix(files): validate URLs from API responses before fetching them (#4146) 
This PR:

- builds on top of https://github.com/ComposioHQ/composio/pull/4144
- routes every fetch whose URL comes from an API response through the
SSRF guards that already existed — ten sinks, five per SDK: the
tool-execution download, both S3 presigned uploads,
`RemoteFile.buffer()`/`blob()`, and the Tool Router session file upload
- adds `safe_request()` (Python), which follows redirects itself and
re-validates each hop, so a validated URL cannot 302 into private space
and an S3 307 region redirect still works
- makes `RemoteFile.buffer()` (Python) share `_fetch_url_bytes` with the
user-supplied-URL path instead of duplicating it — it previously read
`response.content` with no size cap, no redirect control, and no target
validation
- adds `ssrfSafeFetchWhereSupported` (TypeScript): the full guard on
Node, a plain `fetch` on workerd, so Tool Router session file transfers
keep working in edge runtimes rather than failing closed
- documents DNS rebinding as a known residual in both guards
- adds tests that assert the guard *runs* — blocked URL, sink never
called, nothing written — rather than that a transfer succeeds

## Context

`python/AGENTS.md` states the trust boundary: every field of an API
response is untrusted input, because the backend may be compromised or
the connection MITM'd. Both SDKs enforced that for URLs a *user* passes
in (`composio.utils.url_safety`, `ssrfGuard.node.ts`) and left the URLs
an API *response* supplies unguarded — backwards relative to the stated
model. A response naming an internal address turned the SDK into a
request proxy for it, and the fetched bytes were written to disk or
returned to the caller, typically into an LLM context.

`RemoteFile.buffer()` was the weakest of the ten: four lines above it,
`_fetch_from_url` validated its target, refused redirects, and streamed
against a 100 MiB cap; `buffer()` did none of the three. The only
difference between them was which side of the trust boundary the URL
arrived from.

Three decisions worth review:

- **The guard is unconditional.** Presigned URLs are public, so nothing
legitimate should resolve to private space. There is no escape hatch,
and no new configuration surface.
- **The tool-execution download stays uncapped.** It streams straight to
disk, so `_MAX_RESPONSE_SIZE` — a memory-exhaustion bound — does not
apply, and tool attachments legitimately exceed it.
`RemoteFile.buffer()` *is* capped, because it buffers in memory.
- **Uploads follow redirects with re-validation rather than refusing
them**, since S3 can answer a PUT with a 307 region redirect. Downloads
keep `allow_redirects=False`, matching the existing fetch paths.

Python now matches the TypeScript guard's per-hop re-validation, which
was the better of the two implementations.

Verified locally: `make chk` and `make tst` clean on the Python side;
`pnpm -C packages/core test` 1095 passed, typecheck and lint clean.

Alberto Schiabel f67d565743 refactor(python): consolidate path construction from untrusted input (#4144) 
This PR:

- centralizes filesystem path construction for API-provided slugs and
filenames in `composio.utils.safe_path`
- rejects traversal, Windows-invalid names, invalid Unicode, and
overlong encoded filenames before creating directories or writing files
- normalizes trusted roots consistently and routes both Python download
paths through the shared helpers
- adds a fail-closed AST guard for new dynamic path construction,
including direct `Path(...)` calls
- isolates provider initialization from the real home directory and
makes the home-write guard report changes without deleting them
- removes the obsolete download filename wrapper

## Verification

- `pytest -q`: 1,248 passed, 47 skipped
- repository-configured Ruff checks and formatting passed for every
changed Python file
- targeted mypy checks passed for the changed helpers and tests

Alberto Schiabel 09f76b1c9f refactor(cli): eliminate raw environment access (#4134) 
This PR:
- routes Composio-prefixed runtime configuration through `APP_CONFIG`
and normalizes unprefixed host values through `HOST_CONFIG` in
`app-config.ts`
- removes `loadOptionalAppConfig`-style fallback loading so optional
strings, booleans, and CLI flag precedence resolve at the configuration
boundary
- removes every executable `process.env` reference from CLI source;
child commands inherit the ambient environment through
`@effect/platform` and receive explicit normalized overrides
- preserves arbitrary `CODEX_*`, `CLAUDE_*`, and `OPENCLAW_*` detection
through Effect config enumeration without exposing the raw environment
map
- propagates telemetry debug state through worker arguments instead of
mutating the process environment
- replaces removable filesystem, OS, subprocess, and error-handling
exceptions with Effect services and typed control flow
- documents supported and internal CLI environment variables, including
their `user_data.json` and `config.json` mappings
- reduces registered CLI lint boundaries from 45 to 4; the retained
entries are the detached-spawn, Node OS, synchronous preload filesystem,
and MD5 checksum implementations
- verifies the result with 1,201 passing CLI tests (1 skipped), strict
Oxlint, boundary validation, root typechecking across 19 packages, the
CLI build, and real `composio run` child-process checks

Soumya Medapati 83f0f93a72 ci: treat the Vercel project id as a secret; re-pin to rebuilt eval release 
Security review (Sarah): VERCEL_PROJECT_ID moves from a hardcoded value to
a fourth required secret; the eval repo's history was rebuilt without it.
