Individual skill
recall-rationale
Recall why a past change was made, drawing on Codex session history when available and falling back to commit diff and surrounding code. Use when the user asks to "recall the rationale", "find the rationale", "look up the rationale", "why did I do X", "why did we do X", "why was this changed", or "find the transcript for this commit".

# Recall Rationale
Recover why a change was made. Prefer Codex session history when it can be found; otherwise derive the explanation from git history and current code.
## Inputs
Accept any of:
- A commit SHA
- A file path, optionally with a line number (`<path>:<line>`)
- A reviewer question plus surrounding context
- A passage with no commit behind it, because the project is not a git repository or the change is uncommitted
If only a file is given, use `git blame` to resolve the commit that last touched the line.
