Skill Creator

A skill is a prompt the agent loads only for certain work, sometimes with scripts. Two things make one good: it loads exactly when it should, and it costs as little context as the task allows. Everything below serves those.

Before writing one

• List plugins/*/skills/ and check nothing already covers the job. Overlap is worse than a gap: two descriptions competing for the same request means the wrong one loads half the time. Extend the existing skill instead.
• Know who reads it. Skills in this repo run under whatever agent a contributor uses, so write for judgment, not for one model's quirks.

The description is the contract

The description is all the agent sees when deciding whether to load a skill, and every skill's description sits in context at once. Hosts truncate long ones, so length is a shared budget, not a per-skill choice.
