Use these pages to look something up. Each page except the rules is generated from its source in the repo.

- [The rules](/reference/rules): the working rules, and the check that holds each one.
- [Hooks](/reference/hooks): every guard hook, from its own header comment.
- [Skills](/reference/skills): every skill, and when an agent uses it.
- [Template questions](/reference/template-questions): every question that `copier copy` asks.
- [Lead-only rules](/reference/lead-rules): the extra rules for a lead that starts workers.
- [Repo layout](/reference/repo-layout): what each folder and file of the repo holds.
