I left a few comments. Please keep in mind the skill cannot guarantee that its updates to the recipe is sufficient for deployability, and a manual verification step is required at the end.
…nd ergonomics - Production container: run as non-root appuser (UID 1000), multi-stage layer caching, graceful shutdown (--timeout-graceful-shutdown 10), /healthz liveness probe, and PYTHONUNBUFFERED=1. - Multi-agent robustness: add semantic descriptions to subagents for valid Gemini tool declarations, inject ADK session state templates, add search failure fallbacks, and enforce out-of-scope domain boundaries. - A2A & serving: fix agent card interface duplication memory leak, extract public generate_agent_card helper, sanitize Reasoning Engine request parsing to HTTP 400, add root .well-known redirect, and harmonize ports to 8080. - Security & governance: scrub leaked corporate email, harden .dockerignore against credential leaks, add indirect prompt injection defenses, and document least-privilege IAM roles. - Ergonomics & onboarding: add 8-topic Troubleshooting & FAQ to README.md, gate cloud OTel to prevent local container startup hangs, and expand hermetic test_runnability.py coverage.

Avoid calling load_dotenv() in non-__init__ modules. Environment variables should be loaded in the package __init__.py to ensure consistent initialization across all entry points.

Avoid using hardcoded defaults on environment variable reads. These defaults should be moved to .env.example instead; this pattern is present in 6 instances across the recipe.

The request body loading and dictionary validation logic in stream_query (lines 85-101) is duplicated verbatim in the query route (lines 131-147). Consider extracting this validation logic into a shared private helper function to improve maintainability and simplify future schema updates.

The stream generator calls 'method(**kwargs)' directly without checking if the resolved method is a coroutine function. If the method is an async coroutine, it returns a coroutine object instead of an iterable, crashing the stream; check inspect.iscoroutinefunction(method) and await it first as done in the query endpoint.

Accessing the private '_json' attribute of 'request' is unreliable since it is only populated after 'await request.json()' has been called. If the body hasn't been parsed yet, it will return an empty dict and default the A2A-Version to 1.0 even for 0.3 requests; convert 'build' to an async method and await 'request.json()'.

Avoid specifying hardcoded default values inside environment reads like os.getenv. The default should be defined in the .env.example file.

Avoid using bare numeric literals for HTTP status codes. Use appropriate named constants from fastapi.status or http.HTTPStatus instead.

Avoid hardcoding application metadata like title and description strings. Read these values dynamically from package configuration instead.

Do not hardcode dependency names and versions in deploy.py. Parse the requirements dynamically from pyproject.toml to avoid duplication.

Avoid granting world-writable permissions (chmod -R a+w) to the package configuration directory. This violates the principle of least privilege and introduces code-tampering or privilege escalation risks within the container.

Please review the comments left by the agent, and also fix the broken test.
