Spec-driven development for Claude Code · Layered on OpenSpec · v1.5.0

Two commands. One human checkpoint.

Spec a change, read it, then ship it start-to-commit with parallel agents. Every cap the run obeys is a CLI you can run yourself, with no model and no network. Zero-touch is a property of the runtime, not a promise in a prompt.

Every change is spec, then ship. Bootstrap runs once per repo; settle when you want the pull request.

One real run, cut to 34 s. spec asks one question, writes 11 specs and 12 tasks, then stops. ship runs three agents in parallel across two waves and ends in a commit with the suite green, 180 of 180.

12 tasks · 2 waves · 19 agents · 13m 54s · 57 files · 2,881 lines · 180 of 180 pass · 1 commit

Run once, after you clone bootstrap Once per repo. Reads the code, writes an architecture doc and one spec per existing feature. Never modifies source.
settle The pull request, when you want it. Ends by reminding you to archive the change.
