How it works
napkin
When your agent uses it
Maintain a per-repo napkin as a continuously curated runbook (not a session log). Activates EVERY session. Read and curate it before work, keep only recurring high-value guidance, organize by priority-sorted categories, and cap each category at top 10 items. The napkin lives at `.claude/napkin.md`.

# 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:Skills included
