Constraint Check
Checks a proposed change against the load-bearing constraints named in CLAUDE.md / REQUIREMENTS §2 before it lands. Use when a change touches a single-writer DB, deploy invariant, threading model, or other stated invariant.
Explain Back
Explains a just-made change as a cold PR review — why this approach, alternatives considered, test plan, non-obvious invariants. Use when you've accepted a change you don't fully understand and want it justified before moving on.
Phase Kickoff
Opens a roadmap-phase session with an orient → plan → confirm loop before any code — what gets built, files touched, expected smoke output, end-of-phase shape. Use when starting a new roadmap phase. Shims the phase-kickoff module.
Substrate Preflight
Runs the rate-limit / cost / ToS / kill-switch / local-alternative checklist before committing work to a third-party substrate. Use when a phase is about to depend on an external API, paid/metered service, or rate-limited source.
Tight Review
Reviews a diff/PR for structural issues first — behavior changes, smoke gaps, missed call-site updates — holding style nits and improvements until after. Use when you want a focused correctness review of a change before merging.
