# Reference

Lookup pages: the command surface, exit codes and gates, the skill catalogue, the page types. A
reference page describes what is, not how to use it or why it is so - and wherever a source for
it exists in the code, it is generated from that source and checked against it rather than
written by hand.

- [Command reference](commands/README.md) - every `wikitool` command, one page per group,
  generated from the same records as `tools/wikitool <command> -h`.
- [Exit codes and gates](exit-codes.md) - which commands can stop and wait for a person, and
  why.

Page types are not generated here yet; until they are, a page type is described by
`tools/wikitool types describe <type>`.
