The standalone threads template is retired: the ENT-679 rollout was
reverted from main (#5215/#5216/#5217) and the settled model is base
langgraph-python + Intelligence activation overlay. The Intelligence
CLI (main and published copilotkit@3.0.2) no longer references it.
Also drops its two entries from .github/config-allowlist.txt.
The activation overlay's docker-compose.yml relied on a bind-mounted
docker/init-db script to create the intelligence_app database, but the
CLI copies only docker-compose.yml into scaffolded projects. The mount
source never exists there, Docker creates it as an empty directory,
postgres initializes without intelligence_app, and the composite's
migrations fail: 'database "intelligence_app" does not exist' →
'dependency failed to start: container ...intelligence-1 is unhealthy'.
Make the compose file self-contained:
- Set POSTGRES_DB: intelligence_app (drop the init-db bind mount and
the now-unused init script; the shadow DB it also created is only
used by repo-local dev tooling, never by the composite).
- Add an idempotent provision-db one-shot that creates the database
when missing. POSTGRES_DB only applies on first init of an empty
volume, and the volume is shared across all scaffolds via the fixed
compose project name — so machines that already hit the bug have a
data volume without the database. The one-shot heals those on the
next 'docker compose up' with no manual 'down -v'.
- Gate the composite on provision-db completion instead of postgres
health, and align the postgres healthcheck dbname.
The smoke Dockerfile previously relied on a floating `npm install
next@latest` to upgrade crewai-crews from its pinned Next ^15.5.15 to
Next 16. PR #5250 removed that floating line for all starters, which was
correct for the other five but broke crewai-crews: Next 15 cannot
compile @copilotkit/react-core's `export *` re-exports, so the app build
failed.
Pin `next` to 16.2.7 (current latest, the patched build that compiles
react-core and is free of the 16.0.x security advisory) instead of
restoring the floating dependency. Locally, a clean no-cache
docker-compose smoke build compiles, boots, and passes all 4 starter
smoke tests.
The smoke-test app Dockerfiles ran `RUN npm install next@latest` right after
installing the pinned deps from package.json. This overrode the deliberate
`next` pin with a floating version (non-deterministic builds) and added a
flaky network round-trip that broke the agno smoke build with ECONNRESET on
2026-06-04 (run 26972381969). Every affected starter already pins `next` in
package.json (agno 16.0.7, adk 16.1.1, crewai ^15.5.15, llamaindex 16.0.8,
ms-agent-framework-python 16.0.8, pydantic-ai 16.0.7), so the extra install
is pure harm. Removing it makes builds deterministic and removes the network
fragility.
Conflict resolutions:
- contract test: keep the rollout's parameterized version and add
strands-python to migratedIntegrations/appRoots (60/60 passing) in
place of her bespoke MIGRATED_INSTANCES file
- parity manifest: rollout's version with strands' three threads-shield
allowances removed (mirrors the langgraph-fastapi migration); parity
verify green — strands now 88 tracked files, zero drift
- package-lock: regenerated at 1.59.3 (a2ui-renderer stays 1.56.5,
the family-wide pin shared with the north-star)
Also rides: her react-core A2UIMessageRenderer test flake fix
(act -> waitFor), kept intentionally.

Conflict resolution: take the rollout's contract test and append the
agentcore describe block (CDK lambda runtime gate, Vite frontend with
import.meta.env gate, docker env wiring). Bump both agentcore
package.jsons 1.59.1 -> 1.59.3 + regen lockfiles. 54/54.

Conflict resolution: take the rollout's parameterized contract test and
append the a2a-a2ui bespoke tests (namespaced helper, 1.59.3 pins).
Bump a2a-a2ui @copilotkit/* 1.59.1 -> 1.59.3 + regen lockfile. 49/49.

- bump a2a-middleware, mcp-apps, agent-spec from 1.59.1 (their verified
pre-revert state) to 1.59.3 to match the starters
- regenerate package-lock.json for the 11 examples whose package.json
changed (drawer deps re-added on starters, version bumps on the three)
- update the migration contract test's version assertions to 1.59.3
(43/43 passing); oxfmt pass

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 updateProverb useFrontendTool passed the live `agent` object in its
deps array. react-core's use-frontend-tool does JSON.stringify(extraDeps),
which throws "Converting circular structure to JSON" on agent.activeRunDetach$
(an RxJS Subject), crashing the React tree so no assistant bubble renders.
`agent`/`agent.setState` are stable references; only `state` needs to be a
dep. Also bump the docker ag-ui-crewai override to >=0.2.0,<0.3.0 to match
agent/requirements.txt and the showcase backend.
Swap the boilerplate "Create Next App" / "Generated by create next app"
title and description in each starter layout for a per-framework
"<Framework> + CopilotKit Starter" title and matching description.
crewai-flows hardcoded the agent URL with no AGENT_URL env override; add
the fallback to match siblings. agno and llamaindex concatenate a path
suffix onto the base URL, so strip any trailing slash first to avoid a
double slash when AGENT_URL ends in "/".
The welcome message promised theme/proverb/weather tools, but the page
registered none of them (only a debug console.log of agent.state).
Mirror the crewai-flows sibling to wire setThemeColor, the proverbs
shared-state tool, and a weather render tool, remove the leftover
console.log effect, and drop the stray w-screen overflow.
The agno and llamaindex add_proverb frontend tools closed over a stale
`state` snapshot with no dependency array, so rapid successive adds
dropped earlier proverbs. Read agent.state at call time inside the
handler instead. Also drop the stray w-screen on the llamaindex page
that caused horizontal scrollbar overflow.
The smoke build path (docker/Dockerfile.agent) runs `uv sync` against
agent/pyproject.toml + agent/uv.lock, but those still pinned
ag-ui-langgraph==0.0.34 (and the lock still pinned copilotkit==0.1.87).
copilotkit 0.1.93 requires ag-ui-langgraph[fastapi]>=0.0.35, so uv sync
failed with "No solution found" and the langgraph-fastapi smoke job went
red. The prior fix only bumped the production Dockerfile's
`uv pip install`, which the smoke path does not use.
Bump pyproject to ag-ui-langgraph[fastapi]==0.0.37 and regenerate uv.lock
(copilotkit 0.1.87->0.1.93, ag-ui-langgraph 0.0.34->0.0.37). Verified by
building docker/Dockerfile.agent locally: uv sync now resolves and the
agent boots ("Uvicorn running on 0.0.0.0:8123" / "Application startup
complete") serving HTTP 200 on /health.
Also reconcile parity: strands-python's entrypoint.sh legitimately diverges
from the langgraph-python north-star (it boots the strands agent via
`uv run python main.py` and serves Next via `next start`, not serve.py +
standalone server.js). Add entrypoint.sh to strands-python's
allowedDivergence, mirroring how langgraph-js already declares its own
custom entrypoint. parity:check now reports 0 errors.
The entrypoint was copy-pasted from langgraph-python: it logged
'langgraph-python starter', ran 'python serve.py' (no serve.py exists in this
starter), and started Next via standalone 'node server.js' (this image is a
non-standalone .next + node_modules build, so server.js does not exist either).
The container crash-looped on boot with
"python: can't open file '/app/serve.py'".
Run the Strands agent's self-serving agent/main.py via its uv venv
(AGENT_PORT=8123) and serve the frontend with 'next start'. Verified by booting
the image: agent reaches 'Application startup complete' on :8123 and the
container serves HTTP 200 on /.
copilotkit 0.1.93 re-exports StateStreamingMiddleware/StateItem FROM
ag_ui_langgraph.middlewares.state_streaming, which only exists in
ag-ui-langgraph>=0.0.35. The Dockerfiles installed copilotkit with --no-deps
and pinned ag-ui-langgraph[fastapi]==0.0.22, so the middlewares submodule was
missing and the agent crash-looped at boot with
'ModuleNotFoundError: No module named ag_ui_langgraph.middlewares'.
Bump the pin to 0.0.37 (the version copilotkit 0.1.93 resolves with deps).
Verified by booting the langgraph-python image: the agent now reaches
'Application startup complete' / 'Uvicorn running on 0.0.0.0:8123' with no
ImportError, and the container serves HTTP 200 on /.
The strands-python frontend imports `showcaseConfig from "../../showcase.json"`
(via src/hooks/use-example-suggestions.tsx) but the Dockerfile frontend stage
never copied showcase.json into the build context, so `next build` fails with
"Module not found: Can't resolve '../../showcase.json'". Add the COPY step,
mirroring the langgraph-js/langgraph-python Dockerfiles that already copy it.
The @copilotkit/react-core v2 pin (1.59.3) was already correct and matches all
working v2 starters; no package.json change was needed.
The build-starters Docker images hardcoded copilotkit==0.1.78 in the
langgraph-python and langgraph-fastapi Dockerfiles, but their agents import
StateStreamingMiddleware and StateItem, which 0.1.78 does not export. This
crash-loops the Python agent on boot with an ImportError. Bump the hardcoded
pin to 0.1.93 (latest stable, re-exports both symbols, matches local
sdk-python). Align all three langgraph-family agent pyproject pins
(0.1.87 -> 0.1.93) for consistency and regenerate the strands uv.lock.
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).
The v2 migration renamed the Mastra agent key to `default` and updated
page.tsx/index.ts, but layout.tsx was missed: it still pinned
`agent="weatherAgent"` (now non-existent) and lacked
`useSingleEndpoint={false}`. The single-endpoint auto-detect races the
lazily-compiled API route, producing a 404 console error on page load
that fails the @interaction smoke leg's zero-console-error assertion.
Match the passing sibling starters (pydantic-ai/adk/ms-agent-framework-python).
Migrate adk, agno, crewai-crews, crewai-flows, mastra, pydantic-ai, ms-agent-framework-dotnet, ms-agent-framework-python, and llamaindex starters to the CopilotKit v2 `@chat` API and float them to 1.59.3 (package.json, runtime route, layout/page source, lockfiles).
## Summary
- add env-gated CopilotKit Intelligence Threads support to the
`mcp-apps` integration
- move the runtime route to `[[...slug]]` with GET/POST/PATCH/DELETE for
thread REST routes
- wire the Threads drawer + locked gate into the existing MCP apps chat
surface
- align CopilotKit/AG-UI versions and commit npm lockfiles for the app
and Three.js MCP server
- extend the Intelligence migration contract to include `mcp-apps`,
including the app-router path differences
## Verification
- `npm run build` from `examples/integrations/mcp-apps`
- `pnpm exec vitest run
scripts/__tests__/integration-intelligence-migration.test.ts`
- `pnpm exec oxfmt --check
scripts/__tests__/integration-intelligence-migration.test.ts
examples/integrations/mcp-apps/app/page.tsx
examples/integrations/mcp-apps/app/components/threads-drawer/threads-drawer.tsx`
## Licensed smoke
With local Intelligence services from
`/Users/mothra/Projects/test-signups4` and the example `.env` exported:
- `docker compose up -d --wait` reported postgres, redis, and
intelligence healthy
- demo users `1_demo-user` and `demo-user` were seeded/no-op present
- `GET /api/copilotkit/info` returned `mode: intelligence`,
`licenseStatus: valid`, and agent `default`
- `GET /api/copilotkit/threads?agentId=default&limit=20` returned 200
and the Threads drawer rendered persisted threads
- started `npm run dev:mcp` and `next dev --turbopack -p 3024`
- created a new thread, sent “Say hello briefly for the smoke test.”,
`/agent/default/run` returned 200, and the assistant rendered “Hello!”
- after restarting the dev servers, selected the persisted “Quick
Greetings for Testing” thread; the prior user prompt and assistant
response restored, with `/agent/default/connect` returning 200
## Notes
- `3000` was occupied by another local example, so smoke used `3024` for
the Next UI.
- The local thread list contained older experimental thread names from
previous mcp-apps smoke runs; this PR now clears the client thread id
for “New thread” instead of minting a random UUID, so new thread
creation/replay works through the runtime.
Post-merge fix: add the missing examples/integrations/mcp-apps/.env.example
(+ .gitignore negation, crewai-flows precedent) — the contract test
'mcp-apps documents the local Intelligence environment' was failing
because the file was never added. 37/37 passing on the merged tree.

Rename the registered agent key from each starter's bespoke name
(my_agent / agno_agent / starterAgent / sample_agent) to "default" so the
7 single-agent sidebar starters match the passing langgraph/strands
starters' config exactly: drop the frontend `agent=` prop on <CopilotKit>
(falls back to "default") and update the runtime route registration plus
every agentId reference in page.tsx (ThreadsDrawer,
CopilotChatConfigurationProvider, useAgent/useCoAgent).
The functional `useSingleEndpoint={false}` fix that makes starter chat
reach the agent already landed on main; this change brings the agent-key
config in line with the passing set. mastra is intentionally left on its
framework-derived key (MastraAgent.getLocalAgents) — its keys are not
literals and cannot be forced to "default" without diverging from Mastra.
Verified locally via agno docker-compose.test.yml smoke (aimock): @chat
round-trip passes (assistant streams in ~1.0s) with the standardized
"default" key; removing useSingleEndpoint={false} reproduces the documented
404 / "no assistant response" failure (chat degrades to ~1.1m, @interaction
fails on single-endpoint 404s).
Conflict resolution: take main's 4-entry migratedIntegrations array and
keep the a2a-middleware-specific contract tests + helper (a2a-middleware
uses app/ root + custom chat, so it doesn't fit the parameterized
src/app contract). 31/31 passing.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.
