Tyler Slaton ef1ca9808c feat(showcase/google-adk): QA-blitz parity ports — agent prompts, tool surface, e2e specs
Result of 10 parallel QA agents auditing all 30 active demos against
langgraph-python (north-star). Each agent ported drift back to LP-verbatim
across three axes:

1. Agent layer
   - tool_rendering_common.py: rebuilt to LP's surface — get_weather,
     search_flights(origin, destination), get_stock_price, roll_d20,
     roll_dice. Removed the ADK-only query_data.
   - tool_rendering_*_agent.py (4 variants): ported LP's travel/concierge
     prompt; reasoning-chain variant got LP's chain-two-tools prompt.
   - beautiful_chat_agent.py: ported LP's per-tool system prompt; added
     manage_sales_todos / get_sales_todos / generate_a2ui; dropped the
     redundant schedule_meeting (frontend HITL handles it).
   - open_gen_ui_agents.py: ported LP's full SYSTEM_PROMPT for both
     variants, including the Websandbox.connection.remote.* contract
     for the advanced sandbox demo (was `window.sandbox.*`, which the
     LP frontend's Websandbox bridge silently no-ops).
   - byoc_agents.py: fused LP's hashbrown + json-render prompts so the
     single ADK byoc_agent emits both wire shapes. Aliases exported for
     a future per-route split.
   - declarative_gen_ui_agent.py: ported LP's a2ui_dynamic SYSTEM_PROMPT.
   - a2ui_fixed_agent.py: picked up LP's #4734 regression guard
     ("exactly ONCE", "do NOT call again").
   - agent_config_agent.py: rewrote to read useAgentContext (was
     state["config"]); reconciled schema to LP's 3-field camelCase
     {tone, expertise, responseLength} with LP's value enums.
   - subagents_agent.py: dropped the "running" placeholder; returns
     plain str so the LP-verbatim frontend's `result?.trim()` works.
   - hitl_in_app_agent.py / hitl_in_chat_book_call_agent.py: prompts +
     tool-result shape ({approved, reason}) aligned to LP.
   - AGUIToolset() added wherever it was missing on the bespoke agents
     (multimodal, mcp_apps, a2ui_fixed) so frontend-registered tools
     reach the model.

2. Dedicated runtime routes
   - copilotkit-multimodal/route.ts (new) — mirrors LP shape with
     ADK's HttpAgent + AGENT_URL pattern.
   - copilotkit-agent-config/route.ts (new) — same pattern.
   - copilotkit-mcp-apps/route.ts — refreshed.

3. Frontend ports (ADK frontend brought to LP-verbatim where it had
   drifted from the parity blitz state)
   - tool-rendering family (4 demos): full re-port — WeatherCard,
     FlightListCard, StockCard, D20Card, ReasoningBlock, CatchallRenderer,
     suggestions, and the page wiring with all useRenderTool /
     useDefaultRenderTool / reasoningMessage registrations.
   - a2ui-fixed-schema, mcp-apps, multimodal: full frontend re-ports
     with their _components/ Tailwind primitives.
   - frontend-tools, frontend-tools-async, agent-config: ported LP's
     component structure (separate Background, NotesCard with query_notes,
     config-context-relay).
   - shared-state-read, shared-state-read-write, readonly-state-agent-context:
     ported LP's demo-layout + _components + suggestions. recipe-card.tsx
     pulled directly from LP (one QA agent had adapted to Unicode glyphs
     thinking ADK lacked lucide-react — it doesn't, after the parity blitz).
   - shared-state-streaming, subagents, hitl-in-app: ported LP's
     DocumentView / supervisor-activity / TicketsPanel structure.
     hitl-in-app/page.tsx pulled directly from LP to keep the hyphenated
     agent slug aligned with the renamed registry key.
   - auth, hitl-in-chat: ported LP's SignInCard-first auth UX and the
     time-picker Tailwind port.
   - prebuilt-popup: pulled LP's main-content + suggestions split.

4. Test fixtures
   - 30 tests/e2e/<slug>.spec.ts ported from LP, several overwriting
     stale stubs (shared-state-streaming, subagents, auth, hitl-in-chat,
     shared-state-read, agent-config).
   - 30 qa/<slug>.md ported from LP with ADK env-var and registry
     references substituted (GOOGLE_API_KEY, AGENT_URL, registry.py).
   - QA3's byoc-hashbrown / byoc-json-render specs renamed to
     declarative-hashbrown / declarative-json-render with internal
     URL references substituted (the orchestrator pass had already
     renamed the demo dirs + manifest entries).

Frontend changes from QA agents were filtered: kept where they ported
LP-verbatim into ADK, replaced with direct LP pulls where the agent
had made ADK-specific adaptations (one Unicode-glyph case, one
stale-registry-slug case).

Not touched per blitz rules: shared_chat.py, registry.py, manifest.yaml,
src/app/api/copilotkit/route.ts.

QA: Authentication — Google ADK

Prerequisites

  • Demo deployed and accessible at /demos/auth
  • ADK agent backend healthy (check /api/health)
  • GOOGLE_API_KEY set in the deployment

Test Steps

1. Initial unauthenticated state (SignInCard)

  • Navigate to /demos/auth (in a fresh browser session — clear localStorage["copilotkit:auth-demo:token"] if it exists)
  • Verify the SignInCard is visible (data-testid="auth-sign-in-card")
  • Verify the demo token is displayed in plain text (data-testid="auth-demo-token")
  • Verify the "Sign in with demo token" button is enabled (data-testid="auth-sign-in-button")
  • Verify the AuthBanner is NOT yet rendered (data-testid="auth-banner" absent)
  • Verify the chat composer is NOT yet rendered (no "Type a message" placeholder)
  • Verify no console errors on page load

2. Signing in mounts the chat surface

  • Click "Sign in with demo token"
  • Verify the AuthBanner appears with the green/success variant (data-authenticated="true")
  • Verify the auth-status text reads "✓ Signed in as demo user"
  • Verify the "Sign out" button is visible and enabled (data-testid="auth-sign-out-button")
  • Verify the SignInCard is gone (data-testid="auth-sign-in-card" absent)
  • Verify the chat composer is mounted ("Type a message" placeholder visible)
  • Verify no auth-demo-error surface

3. Authenticated send → assistant response

  • Type "Hello" and press Enter
  • Within 30 seconds, an assistant message is rendered ([data-role="assistant"])
  • No auth-demo-error surface appears

4. Sign out flips banner amber, keeps chat mounted

  • Click "Sign out"
  • Within 1 second, the banner flips to the amber variant (data-authenticated="false")
  • Verify the auth-status text reads "⚠ Signed out — the agent will reject your messages until you sign in."
  • Verify the "Sign in" button is visible (data-testid="auth-authenticate-button")
  • Verify the chat composer is STILL visible — page must not return to the SignInCard
  • Verify no white-screen

5. Unauthenticated send surfaces a 401 without crashing

  • After signing out, type "Hello again" and press Enter
  • Within 15 seconds, the page-level error surface appears: data-testid="auth-demo-error" with the runtime's 401 message
  • Verify the banner is STILL visible
  • Verify no assistant response appears

6. Re-signing in clears the error and resumes chat

  • Click "Sign in" (amber-state authenticate button)
  • Within 1 second, the banner flips back to green
  • Verify the auth-demo-error surface is cleared
  • Type "Hello" and press Enter; an assistant response appears within 30s

7. Hard-reload behavior

  • Hard-reload the page (clear cache + reload)
  • With a valid localStorage token, the demo lands directly in the authenticated chat state (no SignInCard)
  • With localStorage cleared, the demo lands on the SignInCard

8. Error Handling

  • With DevTools Network panel blocking /api/copilotkit-auth, send a message while authenticated
  • Verify a network-level error surfaces cleanly (no uncaught promise rejection in console)
  • Restore network; verify sends work again without a page reload

Expected Results

  • Initial paint shows SignInCard (no 401 crash on /info)
  • Banner state flips within 1s of Sign out / Sign in clicks
  • Post-sign-out sends produce a visible 401 error within 15s via auth-demo-error
  • Page never white-screens after sign out — banner and composer stay mounted
  • Authenticated sends produce an assistant response within 30s
  • Token persists across reloads via localStorage; clearing localStorage returns the demo to its first-paint SignInCard state
