1Pre ReleasePre-release is a Release Management agent skill for maintainers of mattpocock’s Sandcastle monorepo who use Changesets to communicate what shipped. It walks the agent through every file in `.changeset` and enforces editorial rules: only user-visible features belong, related work shares one changeset, and prose must explain what changed for users and why—not how it was implemented. Internal refactors without user impact should be excluded. Because `disable-model-invocation` is set, you typically invoke it deliberately as a maintainer ritual rather than letting the model auto-fire mid-session. Solo builders running their own multi-package products get a repeatable pre-launch checklist that keeps changelog noise down and prevents duplicate or overly technical release entries. Finish by committing corrected changesets so CI and the release bot see consistent metadata.8installs
