Traction scoreGitHub stars can be faked, so popularity alone can be misleading. Traction Score looks for broader signs of recent attention, adoption, and active maintenance.
TL;DR

This skill maintains a per-repo runbook at `.claude/napkin.md` that Claude reads and curates at the beginning of every session. It captures recurring gotchas, user directives, and non-obvious tactics — never session logs or one-off mistakes — and organizes them into priority-sorted categories with a strict ten-item cap per category. Each entry includes a date and an explicit "Do instead" action. The effect is that future sessions skip the repetition of past errors and start with accumulated knowledge already applied.

Give it something to do.

Suggested first task

Initialize and curate the repository runbook

Uses napkin

  • The repository in which `.claude/napkin.md` should be maintained
  • Any known recurring corrections, preferences, successful tactics, or repository/toolchain gotchas
Use the napkin skill in this repository. Read `.claude/napkin.md` if it exists; otherwise create it using the documented structure. Curate it into priority-sorted categories containing only recurring, high-value guidance, merge duplicates, remove stale or low-signal notes, keep at most 10 items per category, and ensure every item includes a date and an explicit `Do instead:` action. Use any repository-specific recurring corrections, preferences, or gotchas I provide as input.
