EXECUTE IMMEDIATELY

Step 1: Parse Arguments

Extract from args:
  --version <X.Y.Z>   (required, must be valid semver: digits.digits.digits)
  --dry-run            (optional, preview changes without writing)

If --version is missing or invalid:
  Output: "Usage: /team-shinchan:release --version <X.Y.Z> [--dry-run]"
  Output: "Version must be valid semver (e.g., 4.15.0)"
  STOP

Store: VERSION = extracted version, DRY_RUN = true/false

Step 2: Read Current Version

Read .claude-plugin/plugin.json
Extract current "version" field value
Output: "Current version: {current} -> New version: {VERSION}"

Step 3: Run Release Script

node ${CLAUDE.plugin.directory}/src/release.js <VERSION> [--dry-run]

Review the script output. If it reports errors, stop and show them to the user.

Step 4: Post-Release Actions (skip if --dry-run)

If NOT dry-run:

Stage the 4 changed files:

git add .claude-plugin/plugin.json .claude-plugin/marketplace.json README.md CHANGELOG.md

Create commit:

git commit -m "chore: release v<VERSION>"

Create git tag:
```
git tag v<VERSION>
```

Output summary:

Release v<VERSION> complete!
- 4 files updated
- Commit created: chore: release v<VERSION>
- Tag created: v<VERSION>
- Run `git push && git push --tags` to publish

If dry-run: Output: "Dry run complete. No files were modified."

STOP HERE.
