Agent Skills Tutorial Path: Build Triggerable, Verifiable Skills
Repeating a workflow three times does not automatically mean it should become a Skill. First establish stable triggers, clear inputs and outputs, callable tools, and repeatable verification, then a Skill can reduce drift.
Start with the problem you have
Section titled “Start with the problem you have”| What is happening now | Read first | Your first verifiable result |
|---|---|---|
| You do not know which workflow is worth turning into a Skill | What an Agent Skill actually is | A decision to keep using a prompt or upgrade to a Skill |
| You want to write your first SKILL.md | Your first SKILL.md | A minimal Skill with triggers, steps, and verification |
| A Skill keeps running when it should not | Trigger rules and structure | Checkable triggering and rejection boundaries |
A reusable learning route
Section titled “A reusable learning route”- Collect tasks that repeat reliably instead of turning one-off instructions directly into an asset.
- State a Skill’s inputs, tools, steps, failure states, and actions that require human confirmation.
- Use checklist Skill design to leave a verification gate that can run again for its output.
What to keep after reading
Section titled “What to keep after reading”- A trigger contract that says when to run and when to refuse.
- A minimal description of inputs, outputs, and external dependencies.
- A check or receipt that does not rely only on the model’s own claim.
