Create skill

Create a procedural skill in .agents/skills/<name>/SKILL.md so the parent can invoke a repeatable workflow by name (/name) instead of re-deriving the steps each session.

Before writing, skim existing Homelab skills and (when available) upstream /Users/ianyoung/Projects/prime-context/templates/context/skill-authoring.md.tmpl — conciseness, progressive disclosure, invocation choice, information hierarchy, imperative voice.

When to create a skill

Signal	Action
A multi-step procedure runs 3+ sessions, same steps each time	Create a skill
The parent re-derives the same workflow from scratch each lap	Create a skill
Another skill needs to call this procedure by name	Create a skill (model-invoked)

Do not create a skill when:

• The procedure is one or two steps. Put it in a rule or context module.
• The task is a single role's charter (what it does, not how to do it). That is a persona, not a skill. Use create-agent.
• The workflow is project-specific and unlikely to recur. Keep it in chat or a plan file.

Procedure

1. Name the skill. Use a verb phrase or noun describing the workflow: find-work, review-loop, ship-work. Check .agents/skills/ for collisions.

2. Create the directory:

   .agents/skills/<name>/SKILL.md
   

   Optionally add references/ for long reference material or scripts/ for executable checks. Do not add README.md, CHANGELOG.md, or other non-agent files.

3. Write the frontmatter:

   ---
   name: <skill-name>
   description: >-
     <what it does; include trigger phrases the agent or operator matches on.
     This is the only trigger surface — do not duplicate it in the body.>
   disable-model-invocation: true
   ---
   

   Set disable-model-invocation: true when only the operator should invoke the skill by name. Omit it when the agent should discover the skill autonomously from the description, or when another skill needs to call it. Each model-invoked description sits in the context window every turn, so prefer user-invocation when only the operator needs to reach the skill.

4. Write the body. Structure:

   • Opening — one or two sentences: what the skill does and its boundary (read-only, creates worktree, etc.).
   • Steps — ordered, numbered. Each step ends on a completion criterion the agent can check (done vs not-done).
   • Reference — non-ordered material (tables, pattern catalogs) the agent consults during a step. Keep this in the skill or move to references/ if it is long.
   • Return — what the skill hands back to the parent or operator.

5. Keep SKILL.md lean. Move long catalogs and examples to references/ and load them only when the step needs them. The skill body is the procedure; the references are the library.

6. Update routing. If the skill should be discoverable via AGENTS.md, add a routing table row in pointing at the skill.

Return to parent

Lead with the skill name and one-sentence description. Then:

• File — path created
• Routing — whether AGENTS.md was updated (and the row added)
• Next — suggest a first invocation to test the skill; operator commits
