If you've typed the same long prompt three times this month, it should be a skill: a file Claude runs the same way every time.
What's inside:
a documented SKILL.md template, with a trigger description, inputs, steps, a quality bar and mistakes to avoid
/skill-reviewer: scores a skill on eight checks and lists what to fix
/steal: turns a repo, an article or someone else's framework into a verdict and a version rewritten in your own words, with the licence checked
a GitHub check that every skill has a name and a description
For marketers who've used Claude Code for a few weeks and keep repeating themselves.
Start with the four steps in the README. Week 3 of Marketing Engineering University chains your skills behind an agent and a quality check.
