Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Writing Hookify Rules ## Overview Hookify rules are markdown files with YAML frontmatter that define patterns to watch for and messages to show when those patterns match. Rules are stored in `.codex/hookify.{rule-name}.local.md` files. ## Rule File Format ### Basic Structure ```markdown --- name: rule-identifier enabled: true event: bash|file|stop|prompt|all pattern: regex-pattern-here --- Message to show Codex when this rule triggers. Can include markdown formatting, warnings, suggestions, etc. ``` ### Frontmatter Fields | Field | Required | Values | Description | |-------|----------|--------|-------------| | name | Yes | kebab-case string | Unique identifier (verb-first: warn-*, block-*, require-*) | | enabled | Yes | true/false | Toggle without deleting | | event | Yes | bash/file/stop/prompt/all | Which hook event triggers this | | action | No | warn/block | warn (default) shows message; block prevents operation | | pattern | Yes* | regex string | Pattern to match (*or use conditions for complex rules) | ### Advanced Format (Multiple Conditions) ```markdown --- name: warn-env-api-keys enabled: true event: file conditions: - field: file_path operator: regex_match pattern: \.en

What does the hookify-rules skill do?
This skill should be used when the user asks to create a hookify rule, write a hook rule, configure hookify, add a hookify rule, or needs guidance on hookify rule syntax and patterns.
How do I install it?
Run `npx skills add mturac/everything-openai-codex --skill hookify-rules --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From mturac/everything-openai-codex, a repository with 84 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
