-## Versioning
-
-Keep version fields in sync across:
-
-- `pyproject.toml` — package version
-- `.claude-plugin/plugin.json` — plugin manifest
-- `.claude-plugin/marketplace.json` — marketplace listing (2 occurrences)
-
-### When to bump
-
-Include a **patch** version bump (`x.y.Z`) in any PR that changes skill behavior, scripts, or SKILL.md files. Use **minor** (`x.Y.0`) for new skills/features, **major** (`X.0.0`) for breaking changes. Do NOT bump for docs-only or CI-only changes.
-
-### How to bump
-
-1. Read the current version from `pyproject.toml`.
-2. Compute the new version (patch/minor/major as appropriate).
-3. Update all three files (4 occurrences total) in the same commit.
-4. The PR title should include the new version, e.g., `feat: add foo skill (v0.2.0)`.
-
-### Git tags
-
-The `skills` CLI (`npx skills add`) resolves versions via git tags, not from the JSON version fields. After merging a version-bump PR, create a tag: `git tag v<VERSION> && git push origin v<VERSION>`.
