Turn hunches into accepted results: worthiness score, evidence bar, research-to-rules. Use when vetting ideas. Not for QA; use night-market-validation-and-qa.
Generates and self-executes a diff-derived test plan for a PR. Use when validating PR changes before merge. Do not use for code review; use sanctum:pr-review.
Curate the web-capture index. Use when the capture backlog grows, captures sit unprocessed at seedling/pending, or to surface stored research during work.

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 .claude/hookify.{rule-name}.local.md files.
Create .claude/hookify.dangerous-rm.local.md:
---
name: dangerous-rm
enabled: true
event: bash
pattern: rm\s+-rf
action: block
---
🛑 **Dangerous
Verification: Run the command with --help flag to verify availability.
The rule activates immediately - no restart needed!
name (required): Unique identifier (kebab-case)
enabled (required): true or false
event (required): bash, file, stop, prompt, or all
action (optional): warn (default) or block
pattern (simple): Regex pattern to match
For multiple field checks:
---
name: warn-env-edits
enabled: true
event: file
action: warn
conditions:
- field: file_path
operator: regex_match
pattern: \.env$
- field: new_text
operator: contains
pattern: API_KEY

🔐 **API key in .env file!**
Ensure file is in .gitignore.

If a rule doesn't trigger, verify that the event type matches the tool being used (e.g., use bash for command line tools). Check that the regex pattern is valid and matches the target text by testing it with a short Python script. If you encounter permission errors when creating rule files in .claude/, ensure that the directory is writable by your user.
