Skill Lifecycle Manager

This skill helps you maintain your library of GitHub-wrapped skills by automating the detection of updates and assisting in the refactoring process.

Core Capabilities

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.

Usage

Trigger: /skill-manager check or "Scan my skills for updates" Trigger: /skill-manager list or "List my skills" Trigger: /skill-manager delete <skill_name> or "Delete skill <skill_name>"

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   • Example: "Found 3 outdated skills: yt-dlp (behind 50 commits), ffmpeg-tool (behind 2 commits)..."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.
3. 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.
4. Verify: Runs a quick validation (if available).

Scripts

• 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.

Metadata Requirements

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

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