Keeps package-lock.json in sync with the core bump pulled in from main
(#5489) so the agent lockfile is not stale after the rebase.

The chat never responds and the browser console shows
"TypeError: Failed to execute 'fetch' on 'Window': Illegal invocation"
on every agent run (onRunFailed, agentId: default).
Root cause is in @ag-ui/client@0.0.56's HttpAgent: it stores the global
fetch unbound (`this.fetch = config.fetch ?? fetch`) and later invokes it
as `this.fetch(...)`, so native fetch runs with the agent instance as its
receiver instead of `window`. Native fetch is brand-checked and throws
"Illegal invocation". It surfaces in both dev and prod.
Fixed upstream in @ag-ui/client@0.0.57 (`config.fetch ?? ((url, init) =>
fetch(url, init))`), which shipped in @copilotkit/* 1.60.1. Bumping these
examples 1.60.0 -> 1.60.1 pulls 0.0.57 transitively; lockfiles regenerated.
Scope: only the examples that take @ag-ui transitively from react-core are
bumped here. Other integration examples force-pin @ag-ui via `overrides`
to 0.0.53/0.0.55, where 1.60.1 would create a version skew; those need a
per-integration bump and are intentionally left out of this change.
The langgraph-js smoke-starter job crashes on agent startup with
"'@langchain/core/utils/uuid' does not provide an export named 'v6'".
@langchain/langgraph@1.3.0 depends on @langchain/langgraph-checkpoint@^1.0.2.
Checkpoint 1.1.1 (published 2026-06-12) imports v6 and raised its peer to
@langchain/core@^1.1.48. The agent pinned core 1.1.44, which predates the v6
export. The Docker agent build runs `npm install` against package.json (no
lockfile), so it floats to checkpoint 1.1.1 against the too-old core.
Bumping core to 1.1.49 restores the v6 export and satisfies the peer range.

Bumps every @copilotkit/* pin (react-core, react-ui, runtime, a2ui-renderer,
sdk-js) from 1.59.5 to 1.60.0 across the threads-enabled integration examples,
and regenerates each package-lock.json to the 1.60.0 dependency closure.
Excludes the vestigial langgraph-python-threads example.
The locked-state card told users to add an Intelligence license with
`copilotkit add-intelligence`, but that command only drops the
Intelligence overlay and does not issue a license (and is not yet wired
into the CLI dispatch). The command that issues a license key is
`copilotkit license`.
Restores #5151 (north-star + batch 1 + crewai-flows + llamaindex),
#5196 (pydantic-ai), #5205 (a2a-middleware), #5211 (mcp-apps), reconciled
onto the current main baseline rather than the pre-revert tree:
- keep main's 1.59.3 pins, AGENT_URL normalization, default agent keys,
useConfigureSuggestions, available:false, useRenderTool
status/parameters API, call-time agent.state reads, and crewai-crews'
rebuilt page (not yet threads-migrated)
- graft the threads layer (drawer/gate/provider, env-gated route
intelligence block, next.config gate, env docs, drawer deps) on top
- drop threads-era sidebar suggestions props where main now registers
suggestions via useConfigureSuggestions (or omits them)
- fix the stale pydantic-ai doc link main reintroduced in ms-af-dotnet

The integration-demo parity-check CI job was red on main: langgraph-js,
strands-python, and langgraph-fastapi diverged from the langgraph-python
north-star on two tracked verbatim files.
Root cause is the partial revert in 3721e7b36 (Revert of #5151), NOT #5222.
The v2 API migration (23af69041) moved north-star and all instances to the
v2 surface. The revert rolled the *instances'* example-layout/index.tsx and
docker-route-override.ts back to the v1 API (@copilotkit/react-core,
@copilotkit/runtime) while leaving the north-star on v2
(@copilotkit/react-core/v2, @copilotkit/runtime/v2). That left the demos
internally inconsistent: each instance's real src/app/api/copilotkit route
already uses runtime/v2 on copilotkit 1.59.3, but its Docker route override
and example layout were stuck on v1.
Re-baseline forward by syncing the three instances to the v2 north-star via
`pnpm parity:sync --all`. Only the 5 drifting verbatim files change; no
package.json keys move (all instances already pin 1.59.3) and no
agent-surface or allowed-divergence files are touched. `pnpm parity:check`
is now green (0 errors across all instances).
The starter had two App Router dirs: a stale top-level app/ containing only
an /api/copilotkit route (with a wrong graphId "starterAgent") and the real
src/app/ with page.tsx + layout.tsx. At copilotkit 1.59.3 the build silently
dropped the / route from src/app (masked by next.config ignoreBuildErrors),
producing only /api/copilotkit/[[...slug]]. The app served GET / as 404, so the
docker healthcheck (GET / === 200) never passed and the smoke leg failed with
the app container unhealthy before tests ran.
Removing the duplicate top-level app/ lets Next build src/app unambiguously,
restoring the / route. Local docker-compose.test.yml smoke: app healthy in ~5s,
4 passed (@health, @agent, @chat, @interaction).
Conflict + post-merge resolutions:
- integration test (add/add): fold into the parameterized batch-2 contract
test; migratedIntegrations now includes langgraph-fastapi (24/24 pass).
- _parity/manifest.json: keep her langgraph-fastapi allowance removals
(threads-drawer/page.tsx/next.config now fully tracked), but drop the
stale strands-python shielding her branch added (example-layout +
docker-route-override divergence, @copilotkit 1.56.5 packageJsonOverrides)
— strands is already parity-synced at 1.59.1 on main; those overrides
would have made the next parity:sync rewrite it back to 1.56.5.
- parity verify on the merged tree: langgraph-js 82 ok / langgraph-fastapi
91 ok / strands-python 83 ok, zero drift.

Addresses the blocking review on #5151:
1. Starter smoke 'Popup Assistant' timeouts (adk, agno, mastra,
ms-agent-framework-python/dotnet): the pages passed the dead v1 label keys
(labels.title / labels.initial), which v2 CopilotSidebar ignores — the
header rendered the default 'CopilotKit Chat' so the smoke's
text=Popup Assistant wait timed out. Map to the v2 CopilotChatLabels keys:
title -> modalHeaderTitle, initial -> welcomeMessageText. Verified live:
SSR now renders 'Popup Assistant'.
2. llamaindex TypeError (reading 'proverbs'): the page still used the v1
useAgent API ({ state, setState } = useAgent({ name, initialState })) —
v2 returns { agent }, so state was undefined at render. Migrate to the v2
pattern (agent.state with a guarded default + agent.setState + one-time
seed effect), and fix its dead v1 label keys too. Verified: next build
prerenders all pages cleanly.
3. parity-check drift: ran _parity/sync.ts --all — syncs example-layout
(mobile-header fix), layout.tsx, docker-route-override.ts to the
north-star, and bumps @copilotkit/* to 1.59.1 in langgraph-fastapi and
strands-python. parity verify: 0 errors across all instances.
(next-env.d.ts is gitignored repo-wide; verify warns-and-skips it in a
clean checkout, so it is intentionally not committed.)
4. Trailing-whitespace diff-check failure (showcase google-adk agent): already
resolved by the merge of main (the file matches main; diff --check clean).

Resolves 5 conflicts from main's e793257650 (v2 frontend tool parameters
array -> Zod) overlapping the threads-wired examples:
- adk/mastra/ms-agent-framework-{dotnet,python} page.tsx: keep the branch
versions — they already use Zod parameters and add the threads drawer
wiring + the reviewed v2 restructure on top of what main converted.
- adk/package.json: union — keep the branch's threads-drawer deps +
@copilotkit 1.59.1 bump, and take main's zod dependency (which our adk
page imports but the branch never declared — main's line fixes that gap).

The langgraph-js agent `dev` script ran `npx @langchain/langgraph-cli@1.2.1`,
which resolves its own isolated dependency tree. That tree pulled a 1.2.x
`@langchain/langgraph` to satisfy the `@langchain/langgraph-api` peer
dependency, but the API hard-imports `STREAM_EVENTS_V3_MODES` from
`@langchain/langgraph/web` — a symbol only present in langgraph 1.3.0+ —
crashing the agent at startup with a SyntaxError.
Install `@langchain/langgraph-cli@1.2.4` as a devDependency and invoke the
local `langgraphjs` binary so the `@langchain/langgraph` peer resolves from
the agent's own pinned 1.3.0, which exports the symbol. Verified the agent
boots cleanly (graph registered, API on :8123, no SyntaxError).
The no-license locked panel is a fixed-width (w-80 / 18-20rem) block. In the
single-column mobile grid it left a dead background strip beside it and pushed
the app content down. Hide it below 1024px (max-lg:hidden / .lockedPanel
display:none) — consistent with the real drawer + first-paint placeholder,
which also reserve no column on mobile. Content now gets the full width.
Applied across all 7 migrated examples.

On the no-license locked threads panel:
- widen the panel slightly (w-72 -> w-80 / lockedPanel 18rem -> 20rem) and
add white-space: nowrap so `copilotkit add-intelligence` stays on one line
instead of wrapping mid-command
- add a 'with:' lead-in above the command box so it reads as a runnable command
rather than loose text
Applied across all 7 migrated examples (Card-based locked state in adk/agno/
langgraph-js/langgraph-python; themed .lockedPanel in mastra/ms-agent-*).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The disabled-state ThreadsPanelGate (shown when no Intelligence license is
present) rendered its locked card in a bare `w-72` container with no
background, so the threads column showed the page background (a black column in
dark-themed examples, white in light) instead of the drawer surface.
Give that container the drawer surface (bg + hairline right border) so the
locked card sits in a panel that matches the drawer, consistent with the
already-surfaced .lockedPanel examples (mastra, ms-agent-framework-*).
Affects adk, agno, langgraph-js, langgraph-python (the Card-based locked state).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The ThreadsPanelGate renders a first-paint placeholder while the client-only
drawer mounts. It was either a bare `w-72` div (no surface → a black/white
column flash in the page bg) or a fixed 18rem inline-styled div (correct color
but, on mobile where the mounted drawer floats, the reserved 18rem collapsed on
mount → content shifted left).
Replace both with a shared `.drawerPlaceholder` class that matches the open
drawer's footprint + surface (18rem, drawer bg, hairline border) on desktop and
`display: none` below 1024px (the mobile drawer floats, so reserve no column).
Result: no color flash and no content shift on load. Applied across all 7
migrated examples (themed vs raw surface tokens per example).

Port the langgraph-python mobile-header fix to langgraph-js (same shared
canvas/header demo). Below 1024px the threads drawer's floating launcher is
fixed top-left and collided with the top-left CopilotKit header:
- max-lg:pl-24 on the header so the logo clears the launcher pill
- max-lg:pt-2.5 + pb-0 (and drop the logo span's pb-1.5 on mobile) so the
logo is vertically centered with the launcher + the Chat/App toggle
- trim the collapsed launcher's icon buttons (2rem -> 1.75rem) + tighter
padding so the pill height lines up with the toggle
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Below 1024px the in-flow threads column squeezed the demo content and the
(full-screen) CopilotSidebar chat into slivers. Raise the responsive
breakpoint from 900→1024 and make the panel a true off-canvas overlay:
- collapsed → a small floating launcher pill pinned top-left (z-1300),
above the full-screen mobile chat, so threads stay reachable
- open → a fixed full-height panel sliding in from the left (z-1300),
content + chat use the full width behind it
- default the drawer to collapsed when innerWidth ≤ 1024 on mount
Applied across all 7 integration examples' shared threads-drawer, each
adapted to its own theme tokens (themed examples use --threads-drawer-*,
raw examples use --card/--border for the launcher surface).

Below 900px the drawer already overlays the content when open (existing media
query), but it defaulted to open — so on phones the 16rem panel covered the
content + chat on load. Default isOpen from window.innerWidth (> 900) so narrow
screens start at the 3.5rem rail; the user expands to the overlay on demand.
The drawer is client-mounted, so reading window in the initializer is safe.
Applied to the shared threads-drawer.tsx across all examples + north-star.

- New thread (header + collapsed rail) now switches to a fresh threadId
(crypto.randomUUID()) instead of setting it to undefined. Setting threadId
undefined after a thread was selected did not reset the V2 chat — it kept
showing the previous conversation. A new id forces the configuration provider
to re-thread to an empty conversation.
- Collapsed-rail buttons use a native title tooltip instead of the styled
::after one, which clipped horizontally against the viewport's left edge in
the narrow rail. The wider expanded row keeps the styled tooltip.
Applied to the shared threads-drawer.tsx across all examples + north-star.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The threads-drawer had drifted into two near-identical .tsx variants (a 1-char
encoding diff) during the bespoke passes. Unify all examples onto a single
shared threads-drawer.tsx, which also propagates the mastra review fixes:
- collapsed rail: hover tooltips on the expand + new-thread buttons, and the
non-interactive decorative icon (read as a dead button) removed;
- tooltip renders below the trigger in each example's themed module.css (the
styled ::after tooltip was clipped when shown above the trigger).
Per-example theming (the module.css token values) is unchanged — only the
shared logic + the tooltip positioning rule are reconciled.

The Next route handlers only declared GET/POST, so the threads REST API's
DELETE (delete thread) and PATCH (archive/restore) were 405'd by Next before
reaching the runtime — thread deletion and archive were broken in every
example. Export PATCH + DELETE → handle(app) across all 7 routes.
mastra threads-drawer review fixes:
- tooltip renders below the trigger (the styled ::after tooltip was clipped by
the drawer's overflow containers when shown above);
- collapsed rail drops a non-interactive decorative icon (read as a dead button)
and adds hover tooltips to the expand + new-thread buttons.

Root cause of the parity-check CI failures:
The 5 verbatim-tracked files in `examples/integrations/langgraph-python/`
(the north-star) all carried `typescript/consistent-type-imports` and
`react/self-closing-comp` warnings that oxlint wants to auto-fix.
The lefthook pre-commit `lint-fix` hook is scoped to staged files
and re-stages fixes via `stage_fixed: true`. So when I ran
`pnpm parity:sync --target=strands-python` and staged the synced
files, oxlint --fix rewrote them on commit to satisfy the
type-imports rule — turning `import { NextRequest }` into
`import type { NextRequest }`, etc. The north-star was never touched
by the hook (nothing staged in langgraph-python/), so it kept the
un-fixed form. The two diverged at commit time and parity:check
caught the drift.
Two prior commits (0559faf3d, 80425fcc8) tried to land the sync but
each landed empty: lefthook + stage_fixed reverted the working-tree
changes to match the north-star's un-fixed form, then the linter's
auto-fix re-applied the same delta the hook had just undone — net
zero file content but with the linter-fixed form, which the post-
commit hook then reverted again. Hard to debug because `git
commit` reported success and shortstat hid the no-op.
This commit fixes the root cause instead of the symptom:
1. Apply `pnpm exec oxlint --fix` directly to the 5 north-star
files (`docker-route-override.ts`,
`src/app/declarative-generative-ui/renderers.tsx`,
`src/components/ui/{badge,button}.tsx`, `src/lib/utils.ts`).
The fixes match what the pre-commit hook would have applied:
type-only imports → `import type`, self-closing JSX → `<X />`.
2. Re-run `pnpm parity:sync` for all three instances
(strands-python, langgraph-fastapi, langgraph-js) so they
verbatim-match the new north-star.
3. Verified `pnpm parity:check` exits 0; all four trees lint clean
(`pnpm exec oxlint examples/integrations/.../`).
Net effect: every instance now matches the north-star byte-for-byte,
and the lint-fix hook is a no-op on these files going forward.
Files touched per directory (5 each, except strands-python which had
docker-route-override.ts already synced in a prior attempt):
examples/integrations/langgraph-python/ — 5 files
examples/integrations/langgraph-fastapi/ — 5 files
examples/integrations/langgraph-js/ — 5 files
examples/integrations/strands-python/ — 4 files

The previous commit bumped @langchain/langgraph to 1.3.0 but missed the
peer-dep ripple: langgraph 1.3.0 peers @langchain/core ^1.1.44. The agent
pinned core 1.1.41 and the root override pinned 1.0.1, both below the
required range, so npm install in the agent container failed with ERESOLVE.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
@langchain/langgraph-api@1.2.1 (pulled transitively by langgraph-cli) imports
STREAM_EVENTS_V3_MODES from @langchain/langgraph/web, which only exists in
1.3.0. The starter's overrides + agent dep were pinning langgraph to 1.2.9,
causing the agent container to crash on startup with a SyntaxError. Bump
the override and the direct pin to 1.3.0, and pin @langchain/langgraph-cli
in the npx invocations so future cross-package drift in the LangChain
ecosystem cannot silently re-break this starter.

Rewrite the langgraph-js agent to use `createAgent` from `langchain`
(matching langgraph-python) with `copilotkitMiddleware` and
`stateStreamingMiddleware` from `@copilotkit/sdk-js/langgraph-middlewares`.
Tools now use `ToolRuntime` for state and tool-call-id access. System
prompt inlined in `agent.ts`; drop the file-based `PROMPT.md`.
Replace the legacy single-stage Dockerfile with a Node-only two-stage
build that mirrors the langgraph-python Dockerfile (frontend build →
runner, HttpAgent route override for Docker, Turbopack→webpack).
Add JS-specific `entrypoint.sh` (launches `@langchain/langgraph-cli dev`
+ Next.js standalone) and `docker-compose.test.yml` (wget healthcheck
for the alpine-based agent image, STARTER=langgraph-js default). Both
added to the instance's `allowedDivergence` in the parity manifest.
Rewrite the README to drop Python/uv prerequisites and list the correct
TypeScript tool paths.
Two small changes to the parity tooling, surfaced while validating it on
the langgraph-fastapi port.
1. Drop the per-instance PROMPT.md file. The reference demo
(langgraph-python) does not load agent/PROMPT.md at runtime — it inlines
the prompt as a triple-string literal in agent/main.py. Syncing a
cosmetic PROMPT.md file to every instance created a contract the code
did not follow. Now:
- sync.ts no longer writes agent/PROMPT.md per instance.
- verify.ts greps the first non-blank line of _parity/canonical/PROMPT.md
against each instance's agent source. Inline the prompt string in
source; verifier passes.
- Deleted the now-orphaned PROMPT.md copy under langgraph-js/agent/.
2. Track Dockerfile, docker/Dockerfile.agent, and serve.py in the shared
verbatim-files list. These were previously silent "allowed divergence"
across all instances — any Docker or runtime-adapter drift shipped
unflagged. Now:
- Added to tracked.verbatimFiles in manifest.json.
- langgraph-js keeps them in allowedDivergence (Node-only stack, legit
difference from the Python-based reference).
- langgraph-fastapi drops them from allowedDivergence (same language
stack as the reference; Docker/serve.py should match).
README and the copilotkit-demo-parity skill updated to match the new
prompt contract. Verifier still supports `--target` and exits non-zero on
unexpected drift.
Align langgraph-js with examples/integrations/langgraph-python via the
parity tooling. Remove legacy app/ layout, adopt src/ layout, rewrite
the TS agent to expose the tracked tool surface (manage_todos,
get_todos, query_data, generate_a2ui, search_flights) and todos state,
and write the canonical PROMPT.md. Keeps LangGraphAgent + stategraph
runtime (allowed divergence per the manifest); brings deps,
Dockerfile.app, entrypoint, showcase metadata, and shared UI into
lockstep. Parity verifier: 88 ok / 0 error.
- langgraph-python: replace ephemeral pkg.pr.new URLs with stable @copilotkit/*@1.56.2
- mastra: wire dev to run ui + agent via concurrently (was only starting UI)
- Restore `|| scripts\setup-agent.bat` / `|| scripts\run-agent.bat` fallback across
12 starter templates so npm install + npm run dev work on Windows without Git Bash
- Add --validate-on-load to all aimock invocations (4 workflows/scripts
+ 13 integration docker-compose files)
- Replace hardcoded 2-file fixture list with dynamic discovery across
showcase/, examples/integrations/*/, scripts/doc-tests/ (16 fixtures)
- Add sanity check to prevent silent zero-test pass when discovery fails
- Extend showcase_validate.yml path filter to trigger on
examples/integrations/**/fixtures/** and scripts/doc-tests/fixtures/**
- Import and use ValidationResult type for callback parameters
- Fix scripts/doc-tests/fixtures/default.json to use { fixtures: [...] }
envelope shape
Playwright install stderr is diagnostic signal — version/network errors,
missing system libs, or browser download failures all surface here. Only
suppress stderr on the noisy npm install step. Also pin the image-tag /
client-version relationship with a code comment on one compose file so
future bumps know to keep them aligned.
The Playwright Docker image (mcr.microsoft.com/playwright:v1.52.0-noble)
ships with all Chromium system libraries and browsers pre-installed, so
`--with-deps` adds no runtime value — it only forces a redundant
`apt-get update && apt-get install` inside the tests container.
That apt-get call is the sole source of the intermittent
"Installation process exited with code: 100" / "Failed to install
browsers" failures that rotate across the 12 smoke matrix entries. The
underlying cause is transient Ubuntu archive mirror hash/size mismatches
("File has unexpected size ... Mirror sync in progress?", "Hash Sum
mismatch"), which cause apt to abort with exit 100. Because each matrix
job races apt against archive.ubuntu.com independently, the failing
subset rotates per run (run 24526747926 hit 5 starters; run 24509673514
hit a different 5; run 24495760568 hit 3) — classic flake, not a per-
starter regression.
Dropping --with-deps eliminates the apt-get call entirely. The browsers
themselves are already present at /ms-playwright/chromium-* in the base
image, and `npx playwright install chromium` remains as a cheap no-op
that self-heals if the pinned Playwright version ever drifts from the
image's bundled browser build.
