Task:
- Address the thread as a code author.
- Provide a concise markdown reply only (no JSON, no tool output).
- Use any available skills and MCP tools/resources that help you produce a correct reply.
- Treat this as a single-thread step; do not discuss or modify unrelated threads.
- When referencing files, use `@path/to/file.rs:line` so the TUI can detect and link them.
- Do not run commands or inspect files; reply from this thread context only.
- Do not claim status changes; status is set explicitly by the requester.
- If blocked, explain exactly what input is missing.
