Hooks

Hook configuration (events, properties, matchers, exit codes, environment variables, and HTTP hooks) is maintained in a dedicated repository:

claude-code-hooks — Complete hook reference with sound notification system, all 28 hook events (including PreModelSwitch and PostModelSwitch added in v2.1.252), HTTP hooks, matcher patterns, exit codes, and environment variables.

Hook-related settings keys (hooks, disableAllHooks (also disables any custom status line), allowManagedHooksOnly, allowedHttpHookUrls, httpHookAllowedEnvVars) are documented there.

For the official hooks reference, see the Claude Code Hooks Documentation.
