# Thinking integration plan hardening for junior handoff

## Summary

Refined the thinking-content integration plan to remove execution ambiguity and close known blindspots so a junior engineer can implement directly from the document.

## What changed

- Replaced ambiguous task language with explicit file-level edits and acceptance gates.
- Corrected callback typing to use `StreamingCallback` (existing alias).
- Added missing `process_request(..., thinking_callback=...)` plumbing step.
- Fixed command architecture guidance: `/thoughts` is implemented in `ui/commands`, not in `app.py` inline parsing.
- Added preflight validation for tinyagent thinking stream events.
- Added mandatory neXTSTEP UI skill precondition for UI edits.
- Added explicit text-only extraction requirement for final assistant panel to keep reasoning separate.
- Added concrete test files and ordered verification gates.
