skillctx-sync

Update embedded skillctx-resolve.py scripts across all migrated skills.

When to Use

• After updating the skillctx repo (bug fix in resolve.py, new features)
• User says "skillctx-sync", "update skillctx", or "sync skillctx"

Prerequisites

• Python 3.10+
• Skills must be installed and discoverable by the agent host

Workflow

1. Read current version: Run python <skill-dir>/scripts/sync.py with --help to verify the script is available. Read pyproject.toml in the skillctx repo root for the current version string.

2. Scan for migrated skills: Run python <skill-dir>/scripts/sync.py scan <skills-dir> <current-version> where <skills-dir> is the directory containing installed skills. The script outputs JSON:

   [
     { "skill": "my-skill", "path": "/path/to/my-skill", "version": "0.1.0", "status": "outdated" },
     { "skill": "other-skill", "path": "/path/to/other-skill", "version": "0.2.0", "status": "current" }
   ]
   

   Only skills with <!-- skillctx:begin --> in their SKILL.md are included.

3. Present outdated skills to user: Filter the scan results to "status": "outdated" and show:

   Skills with outdated skillctx resolver:
   - my-skill (v0.1.0 → v0.2.0)
   - another-skill (v0.1.0 → v0.2.0)
   
   Update all? (yes/select/cancel)
   

   Wait for user confirmation.

4. Update each selected skill: For each skill the user approves, run:

   python <skill-dir>/scripts/sync.py update <skill-dir> <resolver-src> <current-version>
   

   Where <resolver-src> is skills/skillctx-ify/scripts/resolve.py (the canonical resolver in this repo). The script:

   • Copies the resolver to <skill-dir>/scripts/skillctx-resolve.py
   • Replaces the <!-- skillctx:begin --> ... <!-- skillctx:end --> block with the latest setup template
   • Updates metadata.skillctx.version in the skill's frontmatter

5. Report what was updated and any errors.

Error Handling

Error	Action
No migrated skills found	Report "no skills using skillctx found"
All skills already current	Report "all skills up to date"
Skill directory not writable	Warn and skip, list at the end
Missing <!-- skillctx:end --> marker	Warn — setup block may be malformed. Skip and list for manual review.
