What it is
A curated set of workflow skills that push an agent toward good engineering habits: plan before building, test first, debug systematically, keep git history clean. The best-known community collection, and a good model for how to write skills.
How it was vetted
Read the repo at commit d884ae0 (2026-07-02) and ran the injection audit
(scripts/injection-audit.mjs) that measures what a skill pack costs you on every
turn.
- Cheap by design. 14 skills, about 577 always-on tokens total (~41 each). The body of each skill loads only when it triggers, so the standing cost is just the descriptions.
- Well-scoped triggers. Descriptions read as “use when X,” which is what makes a skill fire at the right moment instead of always. None were too terse to trigger reliably.
- Opinionated tone. A handful phrase themselves as mandates. Deliberate, and effective, but it’s a firm hand on the wheel. Install it because you want that.
