How to Create a Claude Skill
Step 1: Pick a Narrow Workflow
Good skills are specific. “Review this pull request for risky logic changes” is stronger than “help with coding.”
Step 2: Write the Skill Instructions
Use SKILL.md to describe the goal, triggers, process, output format, constraints, and examples.
Step 3: Test With Real Inputs
Run the skill against inputs that represent normal, edge, and failure cases.
Step 4: Publish With Gotchas
Good skill pages explain where the skill fails. That is what separates a useful skill from a prompt dump.
