- gemini/stack_agent.py: initialize tool_calls/tool_msg before try
block, guard usage with null check to prevent NameError on failure
- gemini/posts_generator_agent.py: use async generate_content to avoid
blocking event loop, guard grounding_metadata access, replace bare
except with explicit bounds check, remove dead router_function and
redundant static edges
- gemini/app/api/chat/route.ts: remove dead OpenAI route from Gemini
example (mislabeled as Gemini-powered, no frontend references it)
- gemini/package.json: remove unused @ai-sdk/openai, ai, zod deps
- langgraph-python/agent.py: remove debug print(state), move docstring
to first position so chat_node.__doc__ works
- textarea tutorial: fix StackBlitz URLs pointing to use-tasks.tsx
instead of use-emails.tsx
