Bump the canonical CopilotKit pin across all showcase integrations + shell
to 1.61.2 (canonical-pins.json, every package.json + package-lock.json),
which carries CopilotKit#5611: passing a catalog to the provider
(`<CopilotKit a2ui={{ catalog }}>`) now auto-enables A2UI and defaults tool
injection on, so the runtime no longer needs an explicit `a2ui` config.
Demonstrate the feature on the A2UI dynamic (declarative-gen-ui) demos by
removing the now-redundant runtime `a2ui` block (`injectA2UITool: true` +
`defaultCatalogId`) from:
- langgraph-python, langgraph-fastapi, langgraph-typescript
- strands, strands-typescript
- google-adk
The forwarded catalog supplies its own catalogId (sdk-js A2UI middleware
auto-derives `defaultCatalogId` from it), so the previous "Catalog not found"
fallback no longer applies.
Verified: validate-pins drift ratchet unchanged (38 / same hash);
langgraph-python D6 `gen-ui-declarative` green end-to-end (no Catalog-not-found).
Bump every @copilotkit/* dependency across the showcase integrations and
the shell from 1.60.2 (and stray "latest" override pins) to an exact
1.61.1 pin, and move the canonical pin source of truth to match.
Regenerate each standalone npm package-lock.json with the same
--legacy-peer-deps flag the Dockerfiles use for "npm ci".
- showcase/integrations/*/package.json + package-lock.json
- showcase/integrations/langgraph-typescript/src/agent/*
- showcase/shell/package.json + package-lock.json
- showcase/scripts/showcase-canonical-pins.json: canonical 1.60.2 to 1.61.1
aimock stays on its own version line (1.26.1). The Python copilotkit SDK
was already 0.1.94 across every requirements.txt, so no change there.
validate-pins ratchet is unchanged (FAIL=38, identical hash);
validate-parity, validate-fixture-tool-surface, and the showcase/scripts
vitest suite (2102 tests) all pass.
Aligns dependency versions across all 19 showcase integrations to current
released minor versions for the 1.60.2 release cycle.
Package families:
- @copilotkit/{a2ui-renderer, react-core, react-ui, runtime, shared, sdk-js, voice}
1.59.4 -> 1.60.2 (18 integrations already staged; ms-agent-harness-dotnet
catches up from 1.57.2)
- @ag-ui/{client, core, encoder} 0.0.55 -> 0.0.57
- @ag-ui/mastra 0.2.1-beta.2 -> 0.2.4 (stable on 0.x; 1.0.x major held back)
Includes the previously-missed ms-agent-harness-dotnet integration in the
@copilotkit/* bump, plus the @copilotkit/web-inspector override pin.
Lockfile-only reconciliation via npm install --package-lock-only
--legacy-peer-deps (cmdk@0.2.1 pre-existing react^18 peer-dep is unaffected).
The A2UI middleware (@ag-ui/a2ui-middleware) forwards injectA2UITool on
forwardedProps; ag-ui-langgraph surfaces it into agent state at
state["ag-ui"]["inject_a2ui_tool"]. The CopilotKit LangGraph middleware
(py + js) now reads that flag and only injects generate_a2ui when it is
truthy (opt-in), drops the runtime's render_a2ui so the model sees one
A2UI tool, and skips if the agent already defines generate_a2ui. The
catalog only binds surfaces; it is no longer the gate.
Reverts the earlier runtime-forward + context-channel approach.
Deps: ag-ui-langgraph>=0.0.38 (py), @ag-ui/langgraph 0.0.37 (sdk-js),
@ag-ui/a2ui-middleware 0.0.6 + @ag-ui/langgraph 0.0.37 (runtime);
.npmrc min-release-age exclude for @ag-ui/a2ui-middleware. Showcase
langgraph pins bumped to copilotkit==0.1.94a3 / sdk-js 1.59.3-alpha.3 /
@ag-ui/langgraph 0.0.37.
Carries ag-ui PR #1784 (skip regeneration check when command.resume is
set) into the three langgraph showcase stacks. ag-ui 0.0.35 incorrectly
ran the regenerate path on a resumed run, breaking the gen-ui-interrupt
D6 cell. 0.0.36 adds the command.resume guard.
Pins @ag-ui/langgraph 0.0.36 via npm overrides (transitive dep of
@copilotkit/runtime) in langgraph-python, langgraph-typescript, and
langgraph-fastapi, and regenerates each per-integration package-lock.json.
The "next" dist-tag was a workaround for Docker builds that can't resolve
workspace:* — but "next" has gone stale (1.55.2-next.1) while "latest" is
at 1.56.5. Renovate doesn't cover showcase/, so these never auto-bumped.
Switch all 19 showcase package.json files to "latest".
Bumps all @copilotkit packages from 1.56.5 to 1.57.2 in both
langgraph-python and langgraph-typescript showcase integrations.
v1.57.2 adds data-testid="copilot-tool-render" needed by the
tool-rendering-default-catchall e2e tests.
Adds npm/pnpm overrides to work around a publish bug in
@copilotkit/web-inspector@1.57.2 where workspace:* leaked
into the published package.json for its @copilotkit/core dep.
Real demo-time bugs in the langgraph-python integration:
- `interrupt-headless` was rendering hardcoded stale slot dates from a
`DEFAULT_SLOTS` constant instead of reading `payload.slots` that the
backend `interrupt(...)` already supplies. Sibling `gen-ui-interrupt`
does this correctly. Headless variant now matches.
- `_shared/interrupt-fallback-slots.ts` (new) — the JS fallback for
when the backend returns no `slots` array. Generates relative to
Date.now() so the picker never shows past dates. Used by both
`interrupt-headless` and `gen-ui-interrupt`. Deletes the old stale-
literal `gen-ui-interrupt/fallback-slots.ts` (dates from April that
had already decayed).
- `interrupt_agent.py` — replaced hardcoded `timezone(timedelta(-7))`
PDT with `zoneinfo.ZoneInfo("America/Los_Angeles")` so the demo
doesn't lie about offsets in winter. Also fixed a Sunday edge case
where `next_monday` collapsed to the same date as `tomorrow` (both
Python and the JS fallback) — added a `<= 1` skip-a-week guard.
- `package.json#dev` ran `uvicorn agent_server:app --port 8000` but
`src/agent_server.py` was a 3-line stub with no `app` symbol AND the
API route pointed at port 8123. Replaced with the canonical
`langgraph_cli dev --port 8123` invocation; deleted the dead stub.
- `entrypoint.sh:47` smoke-checked `src/agents/tools.py` (a file that
never existed) so every Railway boot logged a phantom ERROR. Dropped.
- `reasoning_agent.py` and `tool_rendering_reasoning_chain_agent.py`
intentionally omit `CopilotKitMiddleware` (they exercise only
reasoning-token streaming, no frontend tools / app context). Added a
one-line comment so a future maintainer doesn't cargo-cult it back in.
- `subagents._invoke_sub_agent` text-block walker had a regression
where a `{"type":"text","text":null}` payload (a known provider
quirk) would crash `"".join(parts)` with `TypeError: sequence item
N: expected str instance, NoneType found`. Restored the
`isinstance(block.get("text"), str)` guard.

Switch HITL In-app to CopilotPopup; Shared State Streaming and Read+Write
to CopilotSidebar; widen card-grid breakpoint and add overflow scroll on
Read+Write so content stays usable when the sidebar consumes ~480px of
viewport. Re-skin the read-only Recipe demo with shadcn primitives,
preserving every data-testid and QA-doc-asserted string.
Add clsx and tailwind-merge as direct deps (previously only transitively
resolvable, breaking turbopack dev) and a globals.css rule to neutralize
the Radix scroll-lock padding-right that react-remove-scroll-bar injects
when it mis-detects body's margin-inline-end (CopilotSidebar) as
scrollbar width.
QA docs updated to reference the new chat surfaces.
Closes the demo↔probe coverage gap for /demos/{interrupt-headless,
shared-state-read, tool-rendering-reasoning-chain} so every demo
under langgraph-python (the north-star integration) now has a D5
probe writing to its own PocketBase cell — not relying on cross-
demo umbrella records.
New probes (multi-turn, mirroring the agentic-chat structure):
- d5-interrupt-headless: exercises useHeadlessInterrupt — chip
prompt → backend interrupt(...) → app-surface popup → slot pick
→ resume → assistant confirmation. Distinct from gen-ui-interrupt
(which uses inline useInterrupt).
- d5-tool-rendering-reasoning-chain: combines reasoning-block slot
+ per-tool renderer (WeatherCard, FlightListCard) on the same
chat surface. Catches a regression in either side.
- d5-shared-state-read: recipe-editor demo (neutral default agent,
no tools) — verifies recipe-card form mounts AND agent reads
shared state across turns. Drops the dual-claim that
d5-shared-state.ts had on `shared-state-read` (now write-only).
Driver retry-once (e2e-deep.ts):
Probes that fail with a transient class (`goto-error` /
`conversation-error`) AND took ≥2s on the first attempt now retry
once before recording red. Persistent assertion-style failures
(sub-2s) and intentional aborts/feature-timeouts skip retry —
retrying a deterministic mismatch just burns clock and obscures
the signal. Cuts ~10× the dashboard flap rate.
Plumbing:
- D5FeatureType enum: +interrupt-headless, +tool-rendering-reasoning-chain.
- REGISTRY_TO_D5 (harness) + CATALOG_TO_D5_KEY (dashboard) mirror
the new mappings; d5-mapping-drift test enforces this.
- LGP manifest features + demos entries + constraints allowlist.
- feature-registry.json: +shared-state-read.
- aimock d5-all.json: +2 shared-state-read fixtures (interrupt-
headless + tool-rendering-reasoning-chain reuse existing fixtures
that already match their chip prompts).
Tests: 1588/1588 harness vitest green. validate-fixture-tool-surface
clean (282 fixtures × 627 demos, no drift). Two pre-existing test
fixes folded in — d5-gen-ui-interrupt assertion mock updated to
match the current evaluate-poll resume signal; conversation-runner
preFill ordering test now asserts the actual deferred-cascade
contract instead of a stricter pre-preFill ban that the runner
never enforced.
Known follow-up (not in this PR): auth.spec.ts test #5 ("signing
back in re-mounts a fresh chat surface") fails on Railway — second
sign-in's "Hello again" never produces an assistant response. Looks
like a react-core/v2 ref-handling regression on <CopilotKit>
unmount/remount; deserves its own focused investigation.
Other integrations may flip red on the new probes — that's
expected. We're treating LGP as the template; cross-integration
parity follows in a separate wave.

The branch's iteration arc went through several headless-demo
implementations (CSS Modules, AI Elements, prompt-kit, shadcn) and a
streaming-markdown experiment with `streamdown`. After the spec
narrowed to shadcn-only and `react-markdown` for assistant rendering,
those component libraries and their satellite packages were left
installed but unused.
Removed (zero importers across `src/`):
- @copilotkit/react-ui (v1 UI; the showcase consumes /v2 hooks only)
- @rive-app/react-webgl2 (animations, never wired)
- @streamdown/cjk, /code, /math, /mermaid + streamdown (replaced by
react-markdown for assistant content)
- @xyflow/react (graph viz, never wired)
- ai (Vercel AI SDK, was the AI Elements demo's transport)
- ansi-to-react (terminal output, never wired)
- marked (alternative markdown parser, never wired)
- media-chrome (media player UI, never wired)
- motion (animation library, was a prompt-kit demo dep)
- nanoid (we use crypto.randomUUID())
- react-jsx-parser (never wired)
- remark-breaks (markdown extension, never wired)
- shiki (syntax highlighting, never wired)
- tokenlens (never wired)
- use-stick-to-bottom (was an AI Elements dep)
- @radix-ui/react-use-controllable-state (no importers)
Kept everything actually imported: shadcn primitive surface intact
(class-variance-authority, cmdk, embla-carousel-react, lucide-react,
radix-ui umbrella + per-package @radix-ui/react-checkbox /
react-separator for beautiful-chat's local components), CopilotKit v2,
Hashbrown + json-render BYOC catalogs, recharts, react-markdown +
remark-gfm, openai (voice route), yaml (manifest parsing), zod.
Build still green at 54 routes. Lockfile updated. tsconfig.json
`jsx: "preserve"` — Next 15 reset this from `react-jsx` automatically
on build.
Foundational layer that the per-demo work in subsequent commits builds on.
- Manifest-driven landing page (src/app/page.tsx) — auto-generated grid
of demo cards from manifest.yaml, grouped by tag with explicit ordering
for chat-ui / interactivity / generative-ui / agent-state / multi-agent
/ headless / platform.
- Per-demo titles (src/middleware.ts + src/app/demos/layout.tsx).
- Diagnostic console gated to NODE_ENV=production in app/layout.tsx so
deployed showcases surface uncaught errors and iframe context.
- src/app/globals.css — Tailwind v4 @theme inline block that maps
showcase CSS variables into Tailwind theme tokens (without it, shadcn
utilities like bg-muted / text-foreground compile to nothing). body
intentionally NOT given width:100% so <CopilotSidebar /> can shrink
the document via marginInlineEnd.
- shadcn primitives under src/components/ui/ + src/lib/utils.ts.
- tsconfig.json — @/* path alias rooted at src/.
Removed:
- src/app/copilotkit-overrides.css (global override layer, superseded
by per-demo theming)
- src/app/api/copilotkit-mcp-apps/route.ts (replaced with
[[...slug]]/route.ts so v2 subpath POSTs like /v2/agent/run resolve)
Replace sys.path.insert hacks in Python agent files with direct
imports via symlinks to shared/{python,typescript}/tools.
Update Dockerfiles, entrypoints, and configs to support the new
symlink-based tool resolution. Add PARITY_NOTES for frameworks
that have known gaps.
The showcase framework directories better reflect their role as
integration examples rather than distributable packages.
Renames showcase/packages/ -> showcase/integrations/ and updates
the test docker-compose file reference accordingly.
