+## Releasing
+
+To cut a release:
+
+1. In your PR, bump `VERSION` and sync `.claude-plugin/plugin.json` `.version` to match. The `validate-version` PR check enforces this.
+2. Merge to `main` with `[major]`, `[minor]`, or `[patch]` anywhere in the commit message.
+
+The release workflow reads `VERSION`, creates a `vX.Y.Z` git tag, and publishes a GitHub Release with a repo zip attached. No bot push to `main` — the version bump is part of the PR itself.
+
 ### Submitting to the Claude plugin directory
 
 Use [Submitting your plugin](https://claude.com/docs/plugins/submit). Submit the **public GitHub URL** of this repository — the **repository root** is the plugin root (manifest in `.claude-plugin/`, skills committed under `skills/`, vendored from [jfrog/jfrog-skills](https://github.com/jfrog/jfrog-skills)).
