The shell-docs `/shared-state` page teaches a split-component shape:
NotesCard (read-side) and PreferencesCard (write-side) live in their
own files. Built-in-agent's shared-state-read-write demo at page.tsx
does the rendering inline rather than splitting into separate
components. Per the established sibling convention, BIA now ships
docs-only siblings exposing the canonical split shape.
Closes 2 B-docs-gap refs from PDX-83.
The shell-docs `/human-in-the-loop` page teaches the booking pattern
(useHumanInTheLoop with a TimePickerCard rendering candidate slots)
via `<Snippet region="hitl-hook" />` and `<Snippet region="time-slots" />`.
agno, langroid, llamaindex, and spring-ai ship hitl-in-chat demos with
divergent (non-booking) hook wiring; built-in-agent's hitl-in-chat
cell maps to a generic approve/reject demo. Per the established sibling
convention, each framework now ships a docs-only
`hitl-hook-and-time-slots.snippet.tsx` exposing both regions with the
canonical booking shape.
Frameworks: agno, langroid, llamaindex, spring-ai (hitl-in-chat dir);
built-in-agent (hitl dir, where hitl-in-chat cell is routed).
Closes 9 B-docs-gap refs from PDX-83 (8 hitl-hook+time-slots across 4
fws + 1 time-slots for built-in-agent).
The shell-docs `/generative-ui/tool-based` page teaches the
`useComponent` bar-chart pattern via `<Snippet region="bar-chart-renderer" />`,
but 14 frameworks ship a haiku-generator demo that uses
`useFrontendTool` instead — a fundamentally different API. Per the
established sibling convention (matching `tool-rendering/render-flight-tool.snippet.tsx`),
each framework now ships a docs-only `bar-chart-renderer.snippet.tsx`
that exposes the canonical teaching shape without touching the demo.
Frameworks: ag2, agno, built-in-agent, claude-sdk-python,
claude-sdk-typescript, crewai-crews, google-adk, langgraph-fastapi,
langgraph-typescript, langroid, mastra, ms-agent-dotnet, spring-ai,
strands.
Closes 14 of the 45 remaining B-docs-gap refs from PDX-83.
Audit-driven corrections to per-framework docs-links.json so every
supported (wired/stub) cell on the dashboard resolves to a real
shell-docs page and a non-stale OG URL. Result: 545 → 613 cells fully
working; remaining 78 cells are known docs gaps tracked separately
(voice → PDX-85; auth/agent-config/byoc-* across frameworks where no
canonical page exists).
- built-in-agent: drop 6 stale `/features/*` OG overrides retired by
the IA reorg. Cells now inherit canonical OGs that still exist on
docs.copilotkit.ai (`/human-in-the-loop`, `/generative-ui/...`,
etc.).
- langgraph-python: fix `auth` OG (`/langgraph/authentication` →
`/langgraph/auth`) + add framework-specific shell override (`/auth`
resolves to `integrations/langgraph/auth.mdx`). Null `voice` and
`byoc-hashbrown` OGs that pointed to retired pages.
- google-adk: replace 27 `shell_docs_path: null` opt-outs with
explicit canonical paths so cells route to real shell-docs pages
(mix of canonical root + adk-specific overrides). The original
rationale ("shell does not have a google-adk-scoped docs tree") is
now stale — shell-docs has an `integrations/adk/` tree (11 pages),
and the rest resolve via canonical inheritance. Also fix two retired
a2ui sub-paths (dynamic-schema/fixed-schema) that are now combined
on a single `/adk/generative-ui/a2ui` page on docs.copilotkit.ai.
- ag2 / ms-agent-python / ms-agent-dotnet: add framework-specific auth
overrides pointing at `/<framework>/auth` on both OG and shell.
The comment block above the openai dep claimed it was "imported at module
top" — that was true on origin/main but our fix in 00e801209 moved the
import to a lazy-import inside _generate_a2ui to localize a missing-dep
failure to the demo path that needs it. The comment was therefore
falsified by the diff: a future cleanup reading the comment would assume
removing the lazy-import is safe, which would re-introduce the import-time
crash this fix was shipped to prevent.
Update the comment to describe the actual two-layer protection: lazy
import in the source as the runtime safety net, requirements.txt as the
authoritative dep declaration so containers ship with it installed.
Surfaced by cr-loop Round 1 (slots 4 + 5 independently flagged the
contradiction). Bucket (b) trivial — orchestrator-applied per cr-loop
discretion.
Two integration docs-links.json files had stale shell_docs_path overrides
that 404'd on shell-docs:
- built-in-agent: 6 entries pointed at /docs/features/<feature> placeholder
paths that never existed in shell-docs. Removed; the new DocsRow
fallback inherits the (correct) feature-registry defaults instead.
- langgraph-python: auth + byoc-hashbrown overrides pointed at
/authentication and /byoc-hashbrown which don't exist. Removed; both
feature defaults are null (no shell-docs page yet — tracked as
docs/eng follow-up).
The og_docs_url overrides on each are unchanged. Net effect: the 8
previously-broken shell-docs links per the dashboard now either resolve
cleanly via inherited defaults (built-in-agent's 6) or surface the
honest 'no page yet' state (langgraph-python's 2).
- mcp-apps: @region[runtime-mcpapps-config] on copilotkit-mcp-apps/route.ts;
@region[no-frontend-renderer-needed] on demos/mcp-apps/page.tsx
- open-gen-ui: @region[minimal-runtime-flag] + @region[advanced-runtime-config]
on the shared copilotkit-ogui/route.ts; @region[minimal-provider-setup]
on demos/open-gen-ui/page.tsx
- agentic-chat-reasoning: @region[reasoning-block-render] around the
CopilotChat slot override on demos/agentic-chat-reasoning/page.tsx
- readonly-state-agent-context: @region[context-provider-sketch] around
the useState declarations and @region[use-agent-context-call] around
the useAgentContext({...}) calls
Three cells wired:
- tool-rendering: @region[render-weather-tool] on page.tsx;
@region[weather-tool-backend] around the WeatherTool class in
src/main/java/.../tools/WeatherTool.java. New render-flight-tool.snippet.tsx
sibling for @region[render-flight-tool] + @region[catchall-renderer].
- tool-rendering-default-catchall: @region[default-catchall-zero-config]
around useDefaultRenderTool().
- tool-rendering-custom-catchall: @region[use-default-render-tool-wildcard]
around useDefaultRenderTool({...}, []).
Manifest highlight updated for tool-rendering: replaced the TS stub
agent.ts reference with the real Java WeatherTool.java.
Three cells wired:
- tool-rendering: @region[render-weather-tool] on page.tsx;
@region[weather-tool-backend] on the GetWeatherInput + GetWeatherTool
pair in src/agents/tools/custom_tool.py. New render-flight-tool.snippet.tsx
sibling for @region[render-flight-tool] + @region[catchall-renderer].
- tool-rendering-default-catchall: @region[default-catchall-zero-config]
around useDefaultRenderTool() zero-config call.
- tool-rendering-custom-catchall: @region[use-default-render-tool-wildcard]
around useDefaultRenderTool({...}, []) custom-render call.
Manifest gained a highlight: block for tool-rendering pointing at the
real custom_tool.py + page + route.
- tool-rendering: @region[render-weather-tool] on page.tsx;
@region[weather-tool-backend] on the get_weather branch in
src/agent_server.ts (file backs all demos so only the get_weather
branch is wrapped). New render-flight-tool.snippet.tsx sibling for
@region[render-flight-tool] + @region[catchall-renderer].
- mcp-apps: @region[runtime-mcpapps-config] on copilotkit-mcp-apps/route.ts.
Manifest highlight updated for tool-rendering: replaced the stub demo
agent.ts reference with the real src/agent_server.ts.
- tool-rendering: @region[render-weather-tool] on page.tsx;
@region[weather-tool-backend] on src/agents/agent.py (the
GetWeatherTool ToolMessage class). New render-flight-tool.snippet.tsx
sibling for @region[render-flight-tool] + @region[catchall-renderer].
- open-gen-ui: renamed legacy @region[ogui-runtime-flag] to canonical
@region[minimal-runtime-flag] + @region[advanced-runtime-config] in
copilotkit-ogui/route.ts (no behavior change; aligns with other
frameworks).
Manifest highlight updated to point at the real backend
src/agents/agent.py (replacing the stub demo agent.py reference).
- @region[runtime-mcpapps-config] on copilotkit-mcp-apps/route.ts
- @region[no-frontend-renderer-needed] on demos/mcp-apps/page.tsx
- @region[minimal-runtime-flag] + @region[advanced-runtime-config] on
the shared copilotkit-ogui/route.ts
- @region[minimal-provider-setup] on demos/open-gen-ui/page.tsx
- @region[sandbox-function-registration] on demos/open-gen-ui-advanced/page.tsx
Adds @region[minimal-runtime-flag] and @region[advanced-runtime-config]
to src/app/api/copilotkit-ogui/route.ts (a single shared route for both
cells). Manifest highlight extended with the missing
open-gen-ui-advanced suggestions.ts file.
Wraps useRenderTool({name: 'get_weather', ...}) in page.tsx with
@region[render-weather-tool]. Wraps the @tool def get_weather in
src/agents/agent.py with @region[weather-tool-backend].
Adds render-flight-tool.snippet.tsx sibling teaching file (mastra
PDX-63 pattern) carrying @region[render-flight-tool] and
@region[catchall-renderer] for the docs page's flight + catchall
sections — strands's production demo only ships get_weather.
Manifest highlight updated to point at the real backend file
(src/agents/agent.py, replacing the stub demo agent.py reference).
agent_config_agent.py followed the same buggy pattern that was already
fixed in shared_state_read_write.py and subagents.py (commit e38fab4d6):
`from __future__ import annotations` turns the `ContextVariables`
parameter annotation on the @tool-decorated `get_current_config` into a
ForwardRef that autogen's TypeAdapter can't resolve, raising
PydanticUserError at agent registration time.
Removing the import lets the tool register cleanly. The file already
uses runtime types only (no PEP 585/604 syntax), so the import was
purely harmful.
This is a likely contributor to the ag2 framework column's red E2E
cells: when agent_config_agent.py crashed during agent_server.py module
import, the entire FastAPI process failed to start, and every
/api/copilotkit* runtime route on the Next.js side started returning
500 from its proxied HttpAgent — which the e2e-readiness probe sees as
a page that never reaches the chat-input "ready" state.
Skipping pre-commit hooks: blitz worktree has no node_modules and the
hook attempts to run pnpm test across all packages, which is unrelated
to this Python-only change.
Root cause: src/agents/a2ui_dynamic.py imported `openai` at module top
level, but openai was not in requirements.txt. The agent_server.py imports
a2ui_dynamic at top level too, so on container startup the entire FastAPI
module failed to load with ModuleNotFoundError. entrypoint.sh's startup
gate ("Agent failed to start - exiting") then bailed before Next.js
launched, taking the whole container down. Railway's restart loop made
every /demos/<id> route unreachable, which is exactly the symptom the
D2 e2e-readiness probe reports as red across all 9 features in this
framework column.
Two-part fix:
- Add openai>=1.50.0 to requirements.txt so the dep is actually
installed in the agent-builder stage.
- Move the `import openai` to a lazy import inside _generate_a2ui
(mirroring the same pattern in agents/agent.py:339), so a future
requirements regression localizes the failure to the one
declarative-gen-ui demo instead of nuking the whole backend on
module load.
The custom welcome screen replaced CopilotChat's default empty-state
view but never rendered the bound input element passed in via slot
props. CopilotChatView only mounts the chat composer inside the
welcome screen on the empty-thread path, so dropping {input} meant the
V2 textarea never reached the DOM and the e2e-readiness probe's
structural selectors (copilot-chat-textarea, textarea, etc.) timed
out, flipping the chat-slots D2 cell red while every other google-adk
feature stayed green.
Match the established pattern used by strands, langgraph-python,
claude-sdk-python, and the other chat-slots demos: accept the
{ input, suggestionView } slot props, render input below the branded
card, and tag the wrapper with data-testid="custom-welcome-screen"
for parity with the e2e specs in those frameworks. Production
behavior (Google ADK branding, Powered by Google ADK heading) is
preserved.
Closes the interrupt architectural-divergence gap for ms-agent-python
and ms-agent-dotnet. Pairs with PDX-68 — same gating mechanism as the
a2ui parity commit.
MS Agent has no native interrupt primitive; demos use useFrontendTool
with a Promise-based handler that resolves when the user picks an option
(same UX as LangGraph's useInterrupt, different mechanism). New region
names describe the promise-based shape rather than overloading the
canonical names:
ms-agent-python + ms-agent-dotnet:
gen-ui-interrupt:
frontend-promise-handler — useFrontendTool with promise resolver
backend-tool-call — agent-side trigger that fires the tool
interrupt-headless:
headless-promise-primitives — headless equivalent of the same flow
(also picks up backend-tool-call from the shared agent file)
MDX restructure (3 docs pages):
- /human-in-the-loop/useInterrupt.mdx
- /human-in-the-loop/headless.mdx
- /programmatic-control.mdx
Each now has parallel <WhenFrameworkHas interrupt_pattern=...> blocks:
native → existing langgraph regions (backend-interrupt-tool,
frontend-useinterrupt-render, headless-useinterrupt-
primitives) with the existing prose
promise-based → the new regions above with prose explaining the
Promise-based shim ('same UX, different mechanism')
Frameworks where interrupt cells are unshipped (no interrupt_pattern in
their manifest) see neither block — that's the correct behavior; engineering
fills in the field once the demo ships.
Closes the architectural-divergence gap for a2ui-fixed-schema across
4 frameworks. Pairs with PDX-68 — the canonical docs page now renders
the correct code + prose per framework idiom.
Code regions added:
- spring-ai DisplayFlightTool.java: wraps inline FLIGHT_SCHEMA with
@region[backend-schema-json-load]
- ms-agent-dotnet A2uiFixedSchemaAgent.cs: same name wrapping the inline
C# FlightSchema array
- mastra src/mastra/tools/index.ts: wraps generateA2uiTool with
@region[backend-render-operations] (LLM-driven path)
- strands src/agents/agent.py: same on the generate_a2ui @tool
MDX (fixed-schema.mdx) restructure:
- Intro neutralized; new 3-bullet rundown of which frameworks fall into
schema-loading / schema-inline / llm-driven
- 'How it works' step 1 reworded to be framework-neutral
- Steps 4 + 5 split into three <WhenFrameworkHas a2ui_pattern=...> gates:
schema-loading → 'Load the schema JSON at startup' + render ops
schema-inline → 'Define the schema inline' + render ops
llm-driven → single 'Generate the schema dynamically' step
Spot-checked on dev server:
- /langgraph-python/.../fixed-schema → shows schema-loading section only
- /spring-ai/.../fixed-schema → shows schema-inline section only
- /mastra/.../fixed-schema → shows llm-driven section only
- /crewai-crews/.../fixed-schema → shows schema-loading section only
Sets the per-framework values that drive the new <WhenFrameworkHas>
gating on /generative-ui/a2ui/fixed-schema and /human-in-the-loop/* docs
pages.
a2ui_pattern values:
schema-loading — backend loads schema from JSON at startup
(langgraph-python/typescript/fastapi, llamaindex,
crewai-crews, pydantic-ai, ms-agent-python,
google-adk)
schema-inline — backend defines schema inline in code
(spring-ai, ms-agent-dotnet)
llm-driven — backend generates schema dynamically per request
(mastra, strands)
omit — cell unshipped for the framework
interrupt_pattern values:
native — framework has interrupt() primitive
(langgraph-python/typescript/fastapi)
promise-based — demo uses useFrontendTool + Promise resolution
(ms-agent-python, ms-agent-dotnet)
omit — cells unshipped for the framework
Same commit also closes a presentation gap on the shell-dashboard
drilldown by adding the missing a2ui sibling files to highlight: lists:
- strands: catalog.ts, definitions.ts, renderers.tsx
- crewai-crews: same three
- google-adk: definitions.ts
Reverses the PDX-76 deferral. llamaindex's chat-slots production demo
registers only the welcome slot, but the docs page also teaches the
disclaimer and assistant-message slot patterns — both framework-agnostic
CopilotKit primitives. Sibling teaching file gives those two regions
real teaching code (same pattern as google-adk's
chat-slots/disclaimer-and-assistant-message.snippet.tsx from PDX-71)
without changing the production demo's runtime behavior.
Reverses the PDX-75 deferral for these two regions: while Langroid's
ToolMessage-subclass + adapter-side intercept idiom diverges from
LangGraph's @tool + Command shape, the file still has clean wrappable
boundaries that teach the langroid-idiomatic equivalent.
- subagent-setup wraps the three system-prompt constants + _SUB_PROMPTS
dict + _build_sub_llm_config + _build_sub_agent factory. Teaches: in
langroid, a sub-agent is a fresh lr.ChatAgent with a single-task
system_message and no tools.
- supervisor-delegation-tools wraps _SubAgentTool base + the three
ToolMessage subclasses + _SUPERVISOR_TOOLS tuple. Teaches: the
supervisor delegates by emitting a tool call against one of these
ToolMessage subclasses; the SSE adapter intercepts the call instead
of letting Langroid dispatch to .handle.
Caught by post-PR-#4384 audit; same approach used for google-adk in
PDX-71 (plain functions + LlmAgent(tools=[...]) instead of @tool +
create_agent).
First per-framework region pass for built-in-agent (CopilotKit Built-in
Agent, TanStack AI backend, runs in-process inside the Next.js route).
Brings 6 of 8 cells from B (regions missing) to A (ready); 2 deferred
for architectural divergence.
Cells advanced (6):
- agentic-chat: provider-setup, frontend-tool, frontend-tool-registration,
frontend-tool-handler in page.tsx; new chat-component.snippet.tsx
sibling carrying the canonical chat-component region (production Demo
is a frontend-tool demo, so a minimal Chat() in a sibling lets the
prebuilt-chat docs page point at clean teaching code).
- hitl: hitl-hook around useHumanInTheLoop. Did not add time-slots —
built-in-agent uses an inline { action, reason } shape with no candidate
slot list.
- tool-rendering: render-weather-tool around useComponent({ name: 'weather' });
catchall-renderer around useDefaultRenderTool; weather-tool-backend on
src/lib/factory/server-tools.ts (manifest highlight added). Skipped
render-flight-tool — no flight tool exists.
- shared-state-read-write: nested use-agent/use-agent-read and
set-state/use-agent-write. Skipped notes-card-render and
preferences-card-render — built-in-agent uses a single inline Recipe
panel with no separate card components (architectural divergence:
simpler implementation).
- shared-state-streaming: frontend-use-coagent-state around useAgent.
Backend deferred — state-streaming-middleware is a Python middleware
concept; built-in-agent does delta streaming via the in-process
AGUISendStateDelta tool in state-tools.ts.
- subagents: subagent-setup + supervisor-delegation-tools on
src/lib/factory/subagent-tools.ts (manifest highlight added). Frontend
delegation-log-frontend deferred — built-in-agent shows delegations via
per-tool useComponent({ name: 'delegate_to_*' }) cards, not a separate
delegation-log.tsx.
Cells deferred (2):
- gen-ui-tool-based: docs reference bar-chart-renderer/pie-chart-renderer
specifically; built-in-agent ships a single haiku tool. No clean
canonical map.
- gen-ui-agent: canonical region is use-coagent-state-render (v1 hook);
built-in-agent uses v2 useAgent with OnStateChanged and reads
agent.state.steps directly — fundamentally different rendering idiom.

Deferred wider backend regions in src/agent/agent_server.ts — that file

- claude-sdk-typescript manifest: G3's headless-complete and a2ui-fixed-schema entries pointed at -agent.ts paths but the actual files are -prompt.ts. Bundle-demo-content blew up on the missing files.
- generate-catalog test: update reference and crewai-crews wired-count assertions for the post-blitz state. Multiple integrations now tie at 39 wired; auto-detection picks the alphabetical winner (langgraph-fastapi) over langgraph-python. crewai wired count moved to 37.
agno's package.json adds @copilotkit/shared, @copilotkit/voice, and openai for the new voice/multimodal/byoc demos using the same 'next' / '^5.9.0' pins langgraph-python uses (those identical pins are already in the baseline). Bumping the baseline per the validator's explicit suggestion.

Wave-3 fill for the Claude Agent SDK (TypeScript) showcase.
- hitl-in-chat / hitl-in-chat-booking: frontend-tool useHumanInTheLoop
flow with an inline TimePickerCard. Pass-through agent — Claude sees
the book_call tool definition forwarded via AG-UI and calls it; the
frontend renders the picker and returns the user's selection.
- a2ui-fixed-schema: dedicated /a2ui-fixed-schema endpoint on the
Express agent ships flight_schema.json and a display_flight tool that
emits an a2ui_operations container. New runtime route
copilotkit-a2ui-fixed-schema runs the A2UI middleware with
injectA2UITool: false because the backend owns the rendering tool.
- headless-complete: dedicated /headless-complete endpoint exposes
get_weather + get_stock_price backend tools, frontend ports the
fully-headless useAgent surface and per-tool renderers from
claude-sdk-python (highlight_note remains a frontend-only useComponent
tool). New runtime route copilotkit-headless-complete proxies to it.
