Codex Hooks: event-driven checks and agent automation
Browse source-backed Codex hooks by the event they watch and the action they trigger. Hooks can add validation or automation around tool use, so their configuration matters as much as their name.
What a Codex hook does
A hook responds to a defined event and runs a command, check or automation step around that event. This makes hooks useful for repository safeguards, parity checks and repeatable validation that should happen automatically.
Treat hook code as executable configuration
A hook may be small, but its command can affect files or workflow behavior. Review the matcher, command and parent plugin before enabling it, and use the upstream configuration as the authority.
When a hook deserves its own page
Artifiner keeps thin hook records out of the index until there is enough source-backed context to explain what they do, when they run and how they relate to a real workflow.
