When to use & gotchas
When to use Use a skill when you keep re-explaining the same procedure — wrap the instructions and helper scripts once, and Claude loads them on demand.
Gotcha Skills are model-invoked: a vague description means Claude won't reach for the skill at the right moment. Write the trigger conditions explicitly.

When to use & gotchas
When to use Reach for it when you want an agent that owns a whole task end-to-end — read the repo, run the tests, fix, and open the PR — not just autocomplete.
Gotcha It's only as good as the loop you give it: a clear success check (a test or build it can run) is what lets it self-correct instead of guessing.
