Your first AI skill should be small.
That was hands-down the best advice I got when I ventured into agentic engineering.
Your first AI in the book turns supplied evidence into a bug ticket. That is enough to understand the principles of a skill and to teach the movements. It is easy to grasp and has just enough complexity to show you the ropes.
That is what _Chapter 4 _of Claude Code Beyond the Prompt is all about. You build the first working SKILL.md. You write a description that tells Claude when the skill applies. You define its boundary, method, and output. All in plain English, the programming language of the future.
Once you've written the skill, you test the trigger against different requests:
- one should clearly match.
- one says the same thing in different words.
- one looks similar but should not trigger the skill at all.
That last case is where things get interesting. Getting a skill to trigger is only half the problem. The harder part is making sure it stays out of the way when it should.

A skill that does one job fails in one place, so the broken step is easy to read. Did the trigger break before the output did?
