skill-manager

1. Audit: Scans your local skills folder for skills with github_url metadata.
2. Check: Queries GitHub (via git ls-remote) to compare local commit hashes against the latest remote HEAD.
3. Report: Generates a status report identifying which skills are "Stale" or "Current".
4. Update Workflow: Provides a structured process for the Agent to upgrade a skill.
5. Inventory Management: Lists all local skills and provides deletion capabilities.

Trigger: /skill-manager check or "Scan my skills for updates"

Trigger: /skill-manager list or "List my skills"

Trigger: /skill-manager delete or "Delete skill "

Workflow 1: Check for Updates

1. Run Scanner: The agent runs scripts/scan_and_check.py to analyze all skills.
2. Review Report: The script outputs a JSON summary. The Agent presents this to the user.

* Example: "Found 3 outdated skills: yt-dlp (behind 50 commits), ffmpeg-tool (behind 2 commits)..."

Workflow 2: Update a Skill

Trigger: "Update [Skill Name]" (after a check)

1. Fetch New Context: The agent fetches the new README from the remote repo.
2. Diff Analysis:

* The agent compares the new README with the old SKILL.md.

* Identifies new features, deprecated flags, or usage changes.

1. Refactor:

* The agent rewrites SKILL.md to reflect the new capabilities.

* The agent updates the github_hash in the frontmatter.

* The agent (optionally) attempts to update the wrapper.py if CLI args have changed.

1. Verify: Runs a quick validation (if available).

• scripts/scan_and_check.py: The workhorse. Scans directories, parses Frontmatter, fetches remote tags, returns status.
• scripts/update_helper.py: (Optional) Helper to backup files before update.
• scripts/list_skills.py: Lists all installed skills with type and version.
• scripts/delete_skill.py: Permanently removes a skill folder.

This manager relies on the github-to-skills metadata standard:

• github_url: Source of truth.
• github_hash: State of truth.
