How to Create a Claude Skill

Updated Jun 18, 2026 · By fisher

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.
