Hookify rules for Claude Code workflows require valid YAML frontmatter, event-based detection patterns, regex matching, and response messages to monitor bash commands, file changes, prompts, and completion states.

A hookify rule is a markdown configuration with YAML frontmatter defining event-based detection patterns and response messages. You need one for bash command monitoring to enforce project safeguards like warnings for dangerous commands or sensitive file edits.

Yes, Claude Code hookify rules support regex patterns and advanced multi-condition matching across bash, file, prompt, and stop events to accurately detect specific risky commands or code patterns.

To add a warning for sensitive file edits, define a file change validation hookify rule with correct YAML frontmatter, regex patterns matching target file paths, and conditional matching to trigger the desired warning response message.

Yes, creating hookify rules requires valid YAML frontmatter formatting conventions. The skill enforces correct rule formatting by requiring defined events, regex patterns, conditional matching logic, and properly structured response messages.

Event-based detection patterns in hookify rules are constrained to specific event types: bash command monitoring, file change validation, prompt checks, and completion reminders. Valid regex patterns and conditional matching are required for accurate detection without false positives.
