What problem does it solve? Writing hookify rules requires knowing the exact frontmatter schema, event types, condition operators, and regex escaping conventions; this Skill provides the complete syntax reference so rules are valid and trigger correctly on the first attempt. ## Core Features & Use Cases - Rule File Format: Defines the markdown-plus-YAML-frontmatter structure for rules stored as .juarvis/hookify.{name}.local.md, including required fields (name, enabled, event) and optional action (warn/block). - Simple and Advanced Patterns: Supports single regex patterns for simple rules and multi-condition blocks with fields (command, file_path, new_text) and operators (regex_match, contains, equals, not_contains, starts_with, ends_with) for complex rules. - Event Guidance and Regex Tips: Covers bash, file, stop, prompt, and all event types with common pattern examples (dangerous commands, console.log, .env edits) plus YAML escaping pitfalls. - Use Case: When you want the agent to warn before running rm -rf or block edits adding API keys to .env files, use this Skill to author a correctly structured hookify rule. ## Quick Start Create a hookify rule that warns me whenever a bash command uses sudo or rm -rf.
