Repo Skill Installer

Use this skill when a skill should be hosted by this repository.

Workflow

1. Resolve the skill source.

   • For third-party skills, prefer the GitHub repo path and skill name.
   • For manually hosted skills, use skills/<skill-name>/ as the canonical source.

2. Update the canonical source.

   • Put repo-owned skills under skills/<skill-name>/.
   • Do not vendor third-party payloads there.
   • Keep .agents/skills/ as installer output only.

3. Register the lock entry.

   • Use skills-lock.json as the only source/ref/hash metadata file.
   • For repo-owned skills, use this public repo path: https://github.com/HGZahn/agentic-coding/tree/master/skills/<skill-name>.

4. Rebuild installed output.

   • Install locked skills with npx skills for Codex and opencode.
   • Recompute computedHash from .agents/skills/<skill-name>.

5. Sanity-check the result.

   • Confirm only intended canonical skills, commands, and lock entries changed.
   • Confirm installed .agents/skills payloads remain ignored.

Guardrails

• Do not run broad updates unless every locked skill should refresh.
• Do not modify unrelated commands or skills.
• If the source path is ambiguous, stop and resolve it before copying files.
• If the skill contains only SKILL.md, do not invent extra folders.

Output

When finished, report:

• the skill name
• the source repository/path
• the canonical files changed under skills/
• whether the lockfile hash matches installed output
