Create and register validation hooks for Claude Code to automate safety rails, ensuring validation runs automatically on relevant events like file edits, commits, and pushes.
python skills/hook.define/hook_define.py <event> <command> [options]
Example:
on_file_edit "python betty/skills/api.validate/api_validate.py {file_path} zalando"
--pattern="*.openapi.yaml" --blocking=true --timeout=10000 --description="Validate OpenAPI specs"

Validation hooks automate safety checks on Claude Code events like file edits, commits, and pushes. Use hook.define to create and register hooks in .claude/hooks.yaml, specifying the event, command, and optional pattern, blocking behavior, timeout, and description to run validation automatically.
Hook.define supports on_file_edit, on_commit, on_push, on_file_save, on_tool_use, on_agent_start, and on_workflow_end events. Each event fires validation commands automatically—for example, on_file_edit can validate OpenAPI specs, while on_commit can check for breaking changes.
Yes. Hook.define loads existing .claude/hooks.yaml, deduplicates hooks by name when merging updates, and writes the consolidated configuration back to disk, preventing duplicate hook registrations across multiple runs.
No. Hook.define generates and manages .claude/hooks.yaml programmatically. Provide the event, command, and optional parameters (pattern, blocking, timeout, description) to the skill; it handles YAML creation and updates automatically.
Blocking hooks halt the triggering action if validation fails, enforcing compliance before proceeding. Non-blocking hooks run validation but allow the action to continue. Set blocking=true in hook.define to enforce strict validation gates.
Yes. Use the --pattern option in hook.define to scope hooks to matching file paths—for example, --pattern="*.openapi.yaml" restricts an OpenAPI validation hook to only YAML files matching that pattern.
