The detectFileType function matched any .md file under an agents/ or
commands/ directory, including those nested inside skill content (e.g.
plugins/foo/skills/bar/agents/). These are reference docs, not plugin
agent definitions. Only validate agents/ and commands/ at the plugin
root level.
Adds a GitHub Actions workflow that validates frontmatter in agent,
skill, and command .md files changed by a PR. Checks:
- Agents: name and description are present and parseable
- Skills: description is present (required for Skill tool discovery)
- Commands: description is present and parseable
The workflow only runs when PRs touch files in agents/, skills/, or
commands/ directories, and only validates the changed files.
* Add write permissions for external PR workflow
* Use pulls.createReview instead of issues.createComment
* Revert to issues.createComment with proper permissions
