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: In-App Human in the Loop — Google ADK

Prerequisites

  • Demo is deployed and accessible at /demos/hitl-in-app on the dashboard host
  • Agent backend is healthy (/api/health); GOOGLE_API_KEY is set (or GOOGLE_GEMINI_BASE_URL points at the aimock proxy)
  • Note: Unlike the in-chat HITL demo, the approval UI here is an app-level modal portal'd to document.body and is NOT a child of the chat transcript.

Test Steps

1. Basic Functionality

  • Navigate to /demos/hitl-in-app; verify the page renders within 3s with the "Support Inbox" panel filling the viewport and the CopilotPopup open by default in the bottom-right corner
  • Verify the left header shows the eyebrow "Support Inbox", heading "Open tickets", and the instruction text mentioning "approval dialog here in the app — outside the chat"
  • Verify exactly 3 ticket cards render with test ids ticket-12345, ticket-12346, ticket-12347, each showing the customer name (Jordan Rivera / Priya Shah / Morgan Lee), subject line, and status pill ("Open" green, "Escalating" amber)
  • Verify ticket #12345 displays "Disputed amount: $50.00"
  • Verify the CopilotPopup chat input placeholder is visible (popup opens by default) and no approval dialog is rendered on initial load
  • Send "Hello" and verify the agent responds within 10s

2. Feature-Specific Checks

Suggestions

  • Verify all 3 suggestion pills are visible with verbatim titles:
    • "Approve refund for #12345"
    • "Downgrade plan for #12346"
    • "Escalate ticket #12347"

Approval Flow — Approve Path (useFrontendTool async handler)

  • Click the "Approve refund for #12345" suggestion (or type the equivalent prompt)
  • Within 15s verify an approval modal appears with data-testid="approval-dialog-overlay" (fullscreen fixed backdrop with backdrop-blur-sm) and data-testid="approval-dialog" (centered card with role="dialog" and aria-modal="true")
  • Verify the modal is rendered at the document root (portaled via createPortal(content, document.body)) — confirm in DevTools that approval-dialog-overlay is a direct descendant of <body>, NOT nested inside the CopilotPopup container
  • Verify the modal shows the eyebrow "Action requires your approval", a heading containing the action summary (with concrete numbers such as "$50" and "#12345"), and optional context block below
  • Verify the textarea data-testid="approval-dialog-reason" is present with placeholder "Add a short note the assistant will see…"
  • Type a short note (e.g. "Verified duplicate charge") into the reason textarea
  • Click the data-testid="approval-dialog-approve" button (labeled "Approve")
  • Verify the modal closes immediately and does NOT re-open
  • Verify the agent resumes within 10s and replies in the chat with a one/two-sentence confirmation acknowledging the action is being processed (should reference the refund / #12345)

Approval Flow — Reject Path

  • In a fresh conversation, click "Downgrade plan for #12346"
  • Verify the approval modal re-opens (same testids as above) with a heading referencing Priya Shah / #12346 / Starter plan
  • Type a rejection reason (e.g. "Customer must confirm in writing first")
  • Click data-testid="approval-dialog-reject" (labeled "Reject")
  • Verify the modal closes immediately
  • Verify the agent's reply acknowledges the rejection in one or two sentences, reflects the rejection reason back, and does NOT claim the downgrade was performed

Empty-Reason Path

  • Trigger the approval flow a third time via "Escalate ticket #12347"
  • Leave the reason textarea empty and click Approve
  • Verify the modal closes and the agent still proceeds with the action (reason is optional — omitted when empty)

Modal Is Outside the Chat (Contract Check)

  • While the modal is open, verify the chat transcript inside the popup is still scrollable / visible and does NOT contain an inline copy of the approval UI
  • Confirm that closing the modal via Approve/Reject is the only resolution path — there is no inline "approve" button rendered inside a chat bubble

3. Error Handling

  • Send an empty message; verify it is a no-op (no user bubble, no assistant response)
  • Trigger the approval flow and dismiss via Approve without touching the reason field — verify no console errors and the promise resolves
  • Verify no uncaught console errors during any approve / reject cycle above

Expected Results

  • Chat loads within 3 seconds; initial agent response within 10 seconds
  • Approval modal appears within 15 seconds of the triggering prompt
  • Modal is portaled to <body> (NOT nested in the chat) and closes on Approve/Reject
  • Approve path: agent acknowledges and proceeds; Reject path: agent acknowledges and stops, reflecting the reason when provided
  • No UI layout breaks, no uncaught console errors, no stuck-open modal
