Not every task deserves a skill. But when one does, here's what makes it work.

A strong Claude Code skill has all of these:

☑ Clear identity → Claude knows exactly what this skill is for

☑ Defined scope → what it handles and what it doesn't touch

☑Reasoning order → the steps Claude must follow, no skipping

☑ Output structure → locked format so the result looks the same every time

☑ Repetition test passed → it was proven useful before it was formalized

Structure first. Automation second.
