What events can trigger a Hookify rule?

Rules can trigger on bash commands, file edits (Edit/Write), session stop events, or initial user prompts.

What are Hookify rules in Claude Code?

Hookify rules are project-specific markdown files stored in the .claude/ directory that define patterns for Claude to watch, triggering messages or blocks when those patterns match specific actions.

Can Hookify prevent Claude from executing certain commands?

Yes, by setting the action field to 'block' in the rule's YAML frontmatter, you can stop Claude from proceeding with specific bash commands or file operations.

Which regex flavor does the pattern matching use?

Hookify rules utilize standard Python regex syntax for both simple patterns and advanced multi-condition rules.

Where should I store my Hookify rule files?

Rules must be stored in the project root under the .claude/ directory using the naming format .claude/hookify.{rule-name}.local.md.
