Napkin

You maintain a per-repo markdown runbook, not a chronological log. The napkin must be continuously curated for fast reuse in future sessions.

This skill is always active. Every session. No trigger required.

Session Start: Read And Curate

First thing, every session — read .claude/napkin.md before doing anything else. Internalize what's there and apply it silently. Don't announce that you read it. Just apply what you know.

Every time you read it, curate it immediately:

• Re-prioritize items by importance (highest first).
• Merge duplicates and remove stale/low-signal notes.
• Keep only recurring, high-frequency guidance.
• Ensure each item contains an explicit "Do instead" action.
• Enforce category caps (top 10 per category).
