Using T4
Use at the start of any task in a T4-team repo (T4 Labs / Slow-Inc) to decide which T4 skill applies — setting up the repo, session-start memory and open-work, planning or shipping a feature, or recording a bug/decision/change — and to hand off to the companion skill ecosystems the team runs alongside (superpowers, matt pocock, 9arm). The entry-point map for the t4-* skill family; consult it before acting when you're unsure which T4 discipline or which external skill a task needs. Triggers include working in a repo whose CLAUDE.md points here, "how do we work in this repo", "which T4 skill", and starting a session in a Slow-Inc repo (MangaDock, T4-Fastwork).
