type:review

Instar-specific development skill used by the instar-developing agent (Echo, or any agent assigned instar-dev responsibilities). Wraps /build with mandatory side-effects review, signal-vs-authority principle check, and artifact generation. Structural enforcement via pre-commit/pre-push hooks — the instar repo refuses commits and pushes that didn't come through this skill. NOT a user-facing skill — end users should never invoke it.

From the source SKILL.md

Audience: this skill is for the instar-developing agent (Echo, or any agent assigned instar-dev responsibilities). It is NOT a user-facing skill. End users of instar should never invoke /instar-dev and will never see it in their workflow — it runs at the infrastructure-developer layer, not the per-user application layer. The enforcement hooks on the instar repo ensure the instar-developing agent goes through this skill for every change, but end users never encounter it.
