Update Project Doc — Refresh Stale Documentation

Scan a project's documentation files and update sections that have drifted from reality: file trees, timestamps, bibliography counts, next steps, skill/hook tallies, and more.

When to Use

• After significant project work (new files, completed milestones, structural changes)
• During session-close when offered
• When the user says "update project docs", "refresh docs", "sync my docs", "update my README"
• Periodically to keep documentation accurate

What It Does NOT Do

• Never rewrites research content (hypotheses, arguments, literature, design decisions)
• Never deletes sections — only updates factual/structural content within existing sections
• Never creates new documentation files — only updates existing ones
