You are still on the "why bassclef" question. Read Get started first — the three-command value journey is the shortest path to seeing what the framework does.
Filter by intent
Four buckets, arranged as an adoption sequence — each layer builds on the one before it.
- Tightest 3 (
/riff→/launch→/build) — the value journey. Run these three in sequence to see what bassclef does in a single session (~15 minutes). Not in this bucket? Advanced skills sit in later layers. - The workhorses (
/longrun,/sprint,/luminary,/verify,/kiss,/ticket,/lean-canvas,/session-end) — the discipline-driving skills you invoke every session./longrunand/sprintlead because they drive the session shape. Add these week two. - Beyond starter — skills beyond the tightest 3 and the workhorses, filtered to your active tier. Adopt as needed.
- Author your own — helps you contribute back.
The Tightest 3 and the workhorses are distinct sets: /riff /launch /build prove the value; the workhorses sustain it. If you were expecting /riff /launch /build in the workhorses filter, they're in Tightest 3 — the layer before.
The starter kit every adopter gets by default — enough to run a full session inside your Claude Code harness.

Browse by lifecycle phase
The skills bassclef ships map to eight SDLC phases — Concept → Planning →
Design → Build → Test → Ship → Operate → Adopt. Each skill has one home
phase where the operator reaches for it first; related phases show as a
note on the skill's page. Deep-link to a phase group via /docs/skills#{phase}
(e.g., /docs/skills#planning).
