- Skip copilotkit.connectAgent when CopilotChat lacks a caller-supplied
threadId — a locally-minted UUID has no backend record, so /connect
would always 404 on the intelligence platform.
- Suppress the welcome screen while a connect is in flight and
unconditionally when the caller has supplied a threadId
(hasExplicitThreadId). Prevents the "How can I help you today?"
flash on thread switch.
- Gate suggestions on !isConnecting && !isRunning to avoid painting
them against a mid-replay message tree.
- Defer the isConnecting release by one animation frame so trailing
bootstrap renders commit before the flag flips.
- Reserve room for the "Powered by CopilotKit" license badge via a
new --copilotkit-license-banner-offset CSS var published by the
banner on mount; chat input consumes it only when bottom-anchored.
- Sort and display threads by lastRunAt (fallback to updatedAt →
createdAt) so metadata-only actions like archive/rename don't
reshuffle the list.
- useThreads waits for runtimeConnectionStatus === Connected before
dispatching the store context, eliminating the speculative /threads
fetch that fired before /info returned wsUrl.
Threads example polish: restore button + tooltips on
archive/restore/delete, segmented Active/All filter, graceful error
state, skeleton rows on initial load, stable scrollbar gutter,
pre-paint dark-mode class, logo position stable across app/chat
modes, drop dynamic-import drawer wrapper that caused null first
paint, archived-row dimming via child colors instead of opacity.
Tests:
- CopilotChat.absentThreadConnect: connect is skipped without a
threadId, fires when supplied via prop or config.
- CopilotChatView.connectingGate: isConnecting suppresses welcome;
hasExplicitThreadId suppresses welcome on empty chat.
- threads (core): lastRunAt sort fallback ordering.
- use-threads: Connecting-state gate defers /threads until Connected.

The headless demo component imports from @copilotkit/web-inspector-angular
but the package was missing from package.json and the tsconfig paths,
causing the Angular build to fail with TS2307.

ag-ui-crewai 0.1.5 contains three defects that took down crewai-crews
in prod for 9h on 2026-04-21: unguarded .messages access, orphan
asyncio.create_task, and sync completion() calls. All three are fixed
in 0.2.0 (ag-ui PR #1550).
Showcase already moved to 0.2.x in PR #4115. Dojo is the user-facing
reference — leaving it on 0.1.5 means every reader clones the broken
version. This closes the validate-pins drift.
Pip dry-run resolves ag-ui-crewai-0.2.0 cleanly with no conflicts.
Grep of examples/integrations/crewai-crews/ confirms no consumer code
touches the 0.1.5 defect paths (.state.messages, create_task,
completion sync).
- Keep deletion of sdk-python/copilotkit/langgraph_agent.py (deprecated LangGraphAgent
removed in this PR; main's unrelated bug fixes are superseded by our removal)
- Resolve poetry.lock conflict by taking main's ag_ui_langgraph 0.0.33

The scaffolded BFF was hitting two issues out of the box:
1. tsx doesn't auto-load .env, and the template's .env lives at the
monorepo root. process.env.COPILOTKIT_LICENSE_TOKEN was undefined
at runtime so the runtime logged 'No license token configured'
even when the user had populated .env via `copilotkit license`.
2. @copilotkit/runtime: next resolved to 1.55.0-next.9, which
predates the thread-naming UUID fix (v1.55.3). The BFF blew up
creating LangGraph threads with 'Invalid thread ID: must be a
UUID' because the runtime passed a compound thread-name:<uuid>:
<uuid> string.
Fix both:
- Switch dev script to `tsx watch --env-file=../../.env src/server.ts`
so tsx loads the monorepo root .env.
- Pin @copilotkit/runtime to `latest` so scaffolds get the
thread-naming fix. (The next dist-tag is still stale on npm.)
Switch docker-compose to pull app-api, db-migrations, and realtime-gateway
from public.ecr.aws/cpk/intelligence/* at tag 0.1.0-rc.5 instead of locally
built cpki/*:local images, and drop the build-local-images prerequisite
from the README and compose header.
- 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.
- Remove @langchain/community from sdk-js peerDependencies (unused,
was blocking @langchain/core@1.x resolution)
- Add langchain@^1.0.0 to langgraph-js agent deps to prevent
transitive resolution to 0.3.x
- Add postcss.config.mjs to mcp-apps threejs-server
- Remove '|| .bat' fallback from all starter package.json scripts so
real errors on Linux/macOS are not masked by a failing .bat attempt
- Fix typos: 'isseus' -> 'issues', 'interactin' -> 'interacting'
- Fix crewai-crews README title/body saying 'Flow' instead of 'Crew'
- Fix a2a-a2ui README wrong agent name and file path
- Remove phantom lint/dev:debug scripts from README Available Scripts
sections where those scripts don't exist in package.json
- Add missing dev:ui and dev:agent to mastra README
- chmod +x all new .sh scripts so they work on Linux/macOS
- Use --ignore-scripts in langgraph-js Dockerfiles to avoid postinstall
failure (agent/ dir not yet copied during npm install stage)
- Install agent deps in production Dockerfile after COPY agent/
- Fix hardcoded pnpm commands in agent-spec README
Reorder package manager instructions to show npm first as the default.
Remove stale 'ignores lock files' notes since lock file entries were
removed from .gitignore. All starters now work with npm, pnpm, yarn,
or bun — user's choice.
Starters should not constrain users to a specific package manager.
The .gitignore gets cloned into the user's project, so ignoring
certain lock files would prevent them from committing their chosen
package manager's lock file.
Flatten langgraph-python, langgraph-js, and mcp-apps starters so
npm install && npm run dev works out of the box. Replace Turborepo
with concurrently, move apps/* to root, update Dockerfiles, READMEs,
and entrypoints. Also remove stray pnpm-lock.yaml from a2a-a2ui and
ms-agent-framework-dotnet starters.
## Summary
- **console.css + input.css:** Scope `.dark` CSS selectors to CopilotKit
container elements (`.copilotKitDevConsole
.copilotKitDebugMenuTriggerButton` and `.poweredBy` respectively). The
original selectors had bare `.dark,` as standalone entries in
comma-separated selector lists, which applied styles to *any* element
with class `.dark` instead of scoping to CopilotKit elements.
- **colors.css:** Remove broken `:root` pseudo-element from
`body[style*="color-scheme: dark"] :root` — `:root` is `<html>`, which
cannot be a descendant of `<body>`, so this selector never matched
anything.
- **E2E tests:** 4 Playwright regression tests verifying dark mode
styles don't leak into host application elements.
Prevents CopilotKit dark-mode styles from leaking into the host
application.
Closes#2920

## Summary
- Widen `TanStackChatMessage.content` from `TanStackContentPart[]`
to `any[]` so messages from `convertInputToTanStackAI` are directly
passable to any TanStack AI adapter without `as any` casts
- Split `TanStackContentPart` into a proper discriminated union with
separate variants per modality
- Add `env.d.ts` with `vite/client` reference for CSS import types
- Fix `onError` callback shape in the example
## Test plan
- [x] All 17 multimodal TanStack tests pass
- [x] All 294 agent tests pass
- [ ] Verify no TS errors in react-router example IDE

Remove captured-but-never-asserted colorBefore and markerColorLight
variables. Replace silent if-guard in poweredBy test with explicit
test.skip so missing elements surface in test reports instead of
silently passing.
Verifies that .dark CSS selectors in console.css and input.css are
properly scoped to CopilotKit elements and do not leak into the host
application. Tests detect the specific rgb(69, 69, 69) color leak that
occurred when .dark was used as a standalone selector.
Templates were pinned at old @ag-ui/client versions (0.0.40–0.0.46).
@copilotkit/runtime@1.55.2 ships 0.0.52, which added private fields to
AbstractAgent. The version split caused a nominal type error on build.
