Resolves conflicts:
- manifest.yaml / constraints.yaml / docs-links.json: keep both byoc-json-render
and main's re-wired open-gen-ui + open-gen-ui-advanced entries
- scripts/hooks/check-binaries.sh: keep both shell-docs and shell-dojo
demo-content exclusions (identical lines, different ordering)
- pnpm-lock.yaml (langgraph-python): regenerated via pnpm install
- shell/shell-dojo/shell-docs data JSONs: accept main's deletion (now
regenerated by nx targets), then regenerate via scripts/generate-registry.ts
and scripts/bundle-demo-content.ts
Bump generate-registry.test expected feature/demo count 32 -> 33 to account
for the new byoc-json-render demo.
Resolves textual conflicts in manifest.yaml and docs-links.json (keeps
both open-gen-ui* from main and agent-config from this branch). Accepts
main's deletion of generated shell*/src/data/*.json (now gitignored).
Bumps langgraph-python feature/demo count test from 32 to 33.
Resolved conflicts:
- showcase/packages/langgraph-python/manifest.yaml: kept auth (HEAD) +
open-gen-ui / open-gen-ui-advanced (main) in both features and demos.
- showcase/packages/langgraph-python/docs-links.json: kept auth entry
from HEAD alongside updated subagents shell_docs_path.
- showcase/shared/constraints.yaml: kept auth + open-gen-ui* entries.
- Deleted shell/shell-dojo/shell-docs generated JSONs per main (now
generated at build, no longer committed).
Bumped langgraph-python feature/demo count 32 -> 33 in generate-registry
test to reflect the added auth demo.
Wave 4a. Port the starter's hashbrown renderer into a dedicated
single-mode langgraph-python demo at /demos/byoc-hashbrown so the
byoc-hashbrown row goes green on the dashboard.
- @hashbrownai/core + @hashbrownai/react + recharts deps added.
- Dedicated /api/copilotkit-byoc-hashbrown route with byoc_hashbrown
graph (ChatOpenAI + CopilotKitMiddleware) and a catalog-aware
system prompt coaching the LLM to emit a <ui>...</ui> envelope.
- Ported MetricCard + bar-chart + pie-chart + chart-config from
showcase/starters/template/frontend with data-testid hooks on
chart roots for E2E coverage.
- Ported hashbrown renderer with local RenderMessageProps /
AssistantMessage types so @copilotkit/react-ui and @ag-ui/core
do not become direct deps of this package.
- Updated hashbrown schema calls to @0.5.0-beta.4 surface:
enumeration for SalesStage; description-first streaming.array +
object; dropped the non-existent .optional() chain.
- v2 CopilotChat uses messageView.assistantMessage slot and
useConfigureSuggestions for 3 canned prompts (sales dashboard /
revenue by category / expense trend).
- QA checklist + Playwright E2E authored (not run pre-deploy).
- Manifest / constraints / docs-links updated and derived registry +
demo-content + docs-status bundles regenerated.
- Extend scripts/hooks/check-binaries.sh whitelist to include the
shell-docs and shell-dojo demo-content bundles so the pre-commit
hook does not reject the regenerated 1.5 MB files it produced.
Wire CopilotChat AttachmentsConfig (image + PDF, inline base64) into a
dedicated /demos/multimodal cell backed by a vision-capable LangGraph
agent (gpt-4o). Scoped to its own runtime route so the vision cost
stays on this demo.
- Dedicated /api/copilotkit-multimodal route registering the new
multimodal graph under the multimodal-demo slug
- src/agents/multimodal_agent.py with an AgentMiddleware that flattens
PDF content parts to text server-side via pypdf
- Try with sample image / PDF buttons that drive CopilotChats own
hidden file input via DataTransfer + change event, so the sample and
paperclip paths exercise the same useAttachments pipeline
- public/demo-files/ placeholder — sample.png / sample.pdf binaries
are produced by the user at the end of the Wave 2b rollout
- Manifest + registry + constraints + docs-links wired; normalized
multi-modal -> multimodal in constraints to match the feature
registry id
- QA checklist + Playwright E2E spec (not run yet — pending deploy)
- aimock fixtures for sample prompts so CI runs are deterministic
- Extend the check-binaries hook allowlist to cover the shell-docs and
shell-dojo demo-content.json mirrors (same size as shell/src/data,
already allowed) so regenerated derived data can be committed
Integrates @json-render/{core,react} as an alternative BYOC generative-UI
rendering technology in langgraph-python, paired with Wave 4a's hashbrown
demo. Both demos share the same sales-dashboard catalog (MetricCard +
BarChart + PieChart) so the dashboard rows are directly comparable.
- Adds @json-render/{core,react} @ 0.18.0 pinned.
- New /demos/byoc-json-render page using CopilotChat's messageView.assistantMessage
slot to bridge CopilotKit output into @json-render/react Renderer.
- New /api/copilotkit-byoc-json-render route + byoc_json_render graph in
langgraph.json.
- Zod-validated catalog reusing @json-render/react/schema's prebuilt spec shape.
- System prompt with 3 worked examples inlined so the agent emits valid
{ root, elements } JSON deterministically.
- QA checklist + Playwright spec authored (E2E run deferred to post-deploy
stabilization).
- Adds shell-docs/shell-dojo demo-content.json to the check-binaries.sh
allowlist (same 1MB-allowed rationale as shell/demo-content.json).
Framework-native request authentication demo for the langgraph-python
showcase. Demonstrates both the unauthenticated (401) failure path and
the authenticated success path via a shared bearer token.
- New /demos/auth page with sticky AuthBanner + in-memory React auth state
- Dedicated /api/copilotkit-auth runtime route using createCopilotRuntimeHandler
from @copilotkit/runtime/v2 with an onRequest hook validating
Authorization: Bearer demo-token-123
- Shared DEMO_TOKEN constant imported by both client and server to prevent drift
- <CopilotKit headers={...}> injects Authorization reactively when authenticated
- Page-level error surface captures 401s via onError and renders a stable
data-testid=auth-demo-error for QA + E2E assertions
- QA checklist + Playwright E2E spec authored (E2E run deferred to post-deploy)
- Manifest, feature list, docs-links, constraints, and derived registry /
demo-content / constraints / docs-status data regenerated
- Allowlist shell-docs / shell-dojo demo-content.json in the binary-size
pre-commit hook (mirrors the Wave 2a voice commit; they are bundled
fixtures already over 1 MB on main)
Declare open-gen-ui and open-gen-ui-advanced in langgraph-python
manifest (code existed, was never registered). Add both to
constrained-explicit allowlist, fill shell_docs_path for 5 demos,
add hitl-in-app override, drop stale chat-customization-css fallback.
Regenerate registry.json, demo-content.json, constraints.json,
and docs-status.json across shell / shell-dojo / shell-docs.
Bump feature/demo count assertion 30→32 in generate-registry test.
Extend check-binaries.sh whitelist for sister-shell demo-content.
The scrub and #4084 touched the same surface: #4084 re-added an `open:`
generative_ui profile listing `open-gen-ui`/`open-gen-ui-advanced`, and
re-added both features to `constrained-explicit.allowed`. Extending the
branch's scrub to both re-additions keeps the semantic consistent with
the schema (which already dropped `open` from the approaches enum).
- `showcase/shared/constraints.yaml`: drop `open-gen-ui` +
`open-gen-ui-advanced` from `constrained-explicit.allowed`; drop main's
re-added `open:` profile entirely.
- `showcase/packages/langgraph-python/manifest.yaml`: drop the now-orphan
`open-gen-ui` + `open-gen-ui-advanced` feature and demo entries
(validator confirmed they had no allowed approach left).
- Regenerated `showcase/shell/src/data/registry.json` + sibling
`shell-docs`/`shell-dojo` registries and `constraints.json` via
`pnpm --dir showcase/scripts generate-registry`. All 17 integrations
validate.
`feature-registry.json` intentionally still defines both features — the
original scrub commits (2b996c54d, 27f886e59) left it untouched, so the
demo source files on disk also stay. Follow-up deletion if desired is
out of scope for this merge.
Introduces the "Frontend Tools (Async)" showcase cell — the async sibling
to the in-app-actions "Frontend Tools" cell. Demonstrates the canonical
async useFrontendTool pattern where the handler awaits a real client-side
async operation and RETURNS A RESULT the agent uses.
Concept: a simulated client-side "notes database" query. The frontend
registers a `query_notes` tool whose async handler sleeps 500ms (emulating
IndexedDB / localStorage / local-cache latency) then filters an in-browser
notes array by keyword and returns matching notes. The agent awaits the
result and summarizes matches for the user.
Files:
- src/agents/frontend_tools_async.py — helpful-assistant graph with no
backend tools; system prompt instructs the model to call `query_notes`
for note searches (schema is injected at runtime from the frontend via
CopilotKitMiddleware)
- src/app/demos/frontend-tools-async/page.tsx — CopilotKit provider +
CopilotChat, `useFrontendTool({ handler: async (...) => { await sleep;
return matches; } })` + per-tool render hook that shows a branded
NotesCard, `useConfigureSuggestions` with three prompts
- src/app/demos/frontend-tools-async/notes-card.tsx — emerald/teal
gradient card listing matched notes with tag chips
- langgraph.json — register `frontend_tools_async` graph
- manifest.yaml — features list + demos entry
- feature-registry.json — expanded description + docs URLs point to the
canonical /frontend-tools docs (shared with the sibling cell)
- constraints.yaml — added to all three generative_ui profiles
- docs-links.json — langgraph-python override pointing at /frontend-tools
Validated end-to-end: agent successfully calls `query_notes` with keywords
extracted from natural-language prompts, awaits the async handler, and
summarizes the returned notes for the user.

The "Declarative Generative UI (A2UI — Custom Catalog)" single-file
prototype variant was a testing-only companion to the canonical
declarative-gen-ui 3-file BYOC pattern. Drop it everywhere:
- Delete src/app/demos/declarative-gen-ui-hardcoded/ cell directory
- Delete src/agents/a2ui_dynamic_hardcoded.py
- Remove from langgraph-python manifest.yaml (features + demos) and
langgraph.json graphs
- Remove from docs-links.json, route.ts (agent entry + a2ui agents
list), shared/feature-registry.json, shared/constraints.yaml
- Drop the Callout promoting it from a2ui/dynamic-schema.mdx
- Bump expected langgraph-python count 32 → 31 in generate-registry
test; regenerate all bundles

Pre-Built: Chat was redundant with Pre-Built: CopilotChat — both rows
referred to the same CopilotChat surface with slightly different
framing. Drop prebuilt-chat everywhere:
- Delete src/app/demos/prebuilt-chat/ cell directory
- Remove from langgraph-python manifest.yaml features + demos
- Remove from shared/feature-registry.json features + chat-ui allowlist
- Remove from shared/constraints.yaml constrained-explicit
- Remove from src/app/api/copilotkit/route.ts neutral-fallthrough list
- Update expected counts in bundle-demo-content + generate-registry
tests (langgraph now exposes 32 features, down from 33)
- Fix stale src/agents/main.py test expectation to
src/agents/agentic_chat.py (main.py was split into a neutral assistant
by an earlier Phase-1 fix commit)
- Regenerate shell/src/data/{registry,constraints,demo-content,
docs-status}.json

- Add prebuilt-chat feature to the registry and constrained-explicit
allowlist so the 4085 manifest's intentional prebuilt-chat wiring
validates cleanly (4084 omits it; 4085 committed the cell earlier)
- Bump expected langgraph-python feature count in generate-registry
test from 32 to 33 to reflect the new row

Port the 4084 internal-showcase-followups state of the shared showcase
schema to 4085 (no Docker restructure):
- feature-registry.json: new Dev Ex category, category reorder
(Dev Ex → Chat & UI → Platform → Controlled → Declarative → Open →
Operational → Interactivity → Agent State → Multi-Agent → BYOC);
+8 new features (beautiful-chat, cli-start, interrupt-headless,
reasoning-default-render, tool-rendering-reasoning-chain,
open-gen-ui-advanced, declarative-gen-ui-hardcoded,
readonly-state-agent-context); renames (shared-state-write →
shared-state-read-write, shared-state-agent-readonly →
readonly-state-agent-context); removals (shared-state-read,
state-rendering, a2ui-*, shared-state-io, shared-state, readables,
a2a-chat, deep-agents, vnext-chat, byoc-a2ui, byoc-tambo);
gen-ui-agent → kind: testing.
- constraints.yaml: allowlists updated to reference the new IDs.
- manifest.schema.json: `route` is optional; `command` field added for
informational demos (e.g. cli-start).
- All 17 column manifests: shared-state-read removed,
shared-state-write renamed to shared-state-read-write.
- langgraph-python manifest: full 4084 features list + demos entries
with 4085-appropriate highlight paths (src/agents/*.py +
src/app/demos/<cell>/* rather than backend/ + frontend/).

Split generative-ui category into 4 (controlled/declarative/open/
operational), add chat-customization-css + tool-rendering-frontend-tools,
replace old tool-rendering-status/-result IDs with default-catchall /
custom-catchall. Port langgraph-python manifest features + highlight:
paths (column-relative to preserve pre-existing Docker structure).
Update tests for new category/feature counts.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds rows for the demos being built in this branch:
- Split `chat-prebuilt` into `prebuilt-chat`, `prebuilt-sidebar`,
`prebuilt-popup` (CopilotChat / CopilotSidebar / CopilotPopup).
- Reorder `generative-ui` rows and add: `hitl-in-chat` (In-Chat HITL),
`gen-ui-interrupt`, `declarative-gen-ui` (Dynamic Schema),
`a2ui-fixed-schema` (new), `mcp-apps`, `open-gen-ui`, `gen-ui-agent`,
`tool-rendering`.
- `constraints.yaml`: expand `constrained-explicit` allowlist so the
langgraph-python manifest validates against the new feature ids.
- Bump expected langgraph-python feature/demo count in
`generate-registry.test.ts` from 10 -> 22 to match the manifest.
