v0.2.0

Added

• release short-circuits gracefully when the CHANGELOG top version is already a local git tag — emits EXISTS:tag/<tag>:already released — bump CHANGELOG to release a new version and exits 0 without touching manifests, commits, or push. Catches the most common slip: running release after a docs-only commit without bumping the CHANGELOG. Applies to plain release, release --publish, and release --dry-run.

Documented

• CLAUDE.md gains a "Release discipline" section with a per-change-type decision table (bug fix / new feature / breaking → release --publish; docs / tests / refactor without behavior change → plain commit) and an explicit description of the short-circuit safety net.
• SKILL.md and README.md updated to describe the short-circuit behavior.
