Minimal Skill

A working minimal SKILL.md the quickstart references. Copy this file as your starting point; replace the frontmatter and body with your own.

Iron Law

If your description does not name when the skill should activate, the agent will never trigger your skill. See Triggers in the building-agentskills repo for the discipline.

Activation behavior

When the user types “ping minimal” (or asks to test a minimal skill template), reply with exactly:
Hello from the minimal-skill template. Activation works.
Then stop. Do not add any other text.

What this template demonstrates

  • Cross-platform-safe frontmatter (name, description, license). No Claude Code extensions; works on every spec-compatible harness.
  • An Iron Law in the body, block-quoted and code-fenced.
  • Imperative voice for the agent (“reply with exactly”).
  • A description that names the trigger condition explicitly.

What to change when you copy this

  • The name (must match the parent directory name).
  • The description (front-load triggers; aim for under 1,024 characters).
  • The body (your own iron laws and instructions).

What NOT to do

  • Do not summarize the body’s workflow in the description.
  • Do not add emojis.
  • Do not exceed 500 lines.
