What problem does it solve? Release work involves coordinating version bumps, changelogs, lockfiles, tags, and rollback plans across many artifacts, and mistakes can break users or shared environments. This Skill structures release preparation so agents produce evidence and plans while humans retain control of anything that mutates shared environments. ## Core Features & Use Cases - Release Unit Classification: Maps release units from manifests, lockfiles, workspace config, and tags, then classifies impact to choose the correct semver bump per unit, including monorepos with independent streams. - Artifact Synchronization: Keeps manifests, committed lockfiles, CHANGELOG entries, tag plans, dependency ranges, and publish order moving together, with validation via dependency resolution and dry-run packaging. - Rollout and Rollback Planning: Prepares rollout plans with named artifacts, environments, operators, and gates, plus rollback covering data, caches, config, and external side effects. - Deprecation and Migration Guidance: Loads a dedicated reference for advisory deprecations, compulsory migrations, removals, and internal cleanups with proof obligations. - Use Case: After a breaking API change is approved, use this Skill to determine the major version bump, update the changelog and lockfile together, and draft a rollback runbook for a human operator to execute. ## Quick Start Ask the agent to prepare the release for the approved changes, including version classification, changelog updates, and a rollback plan.
