Doc Stale

Find and review stale documentation that may need updating. Use this skill when the user asks about outdated docs ("are any docs stale", "which docs need updating", "doc freshness", "check for outdated documentation", "what docs are affected by recent changes", "doc drift", "are my docs up to date", "documentation audit"), wants to know the doc impact of code changes ("I changed X, what docs need updating", "which docs should I review before merging", "did I forget to update any docs", "doc impact of my changes", "update docs for this PR"), or needs to identify documentation that has fallen behind the codebase. Also use when the user asks to review or verify docs after refactoring, renaming, or removing code. This skill wraps the docnav stale command — always prefer it over manual git-diff-and-grep when checking doc freshness.
