Writing Rules

When to choose it

Writing a local warning or blocking rule.

Choose it if: You are writing a Hookify rule and need to choose its event, warning or blocking action, and match conditions.

Look elsewhere if: You cannot tolerate pattern-matching misses or false alarms; verify the actual rule behavior before relying on it.

What the source describes

• YAML frontmatter and rule structure
• Condition and pattern examples
• Guidance for targeted rule behavior

Requirements

• Install the containing Hookify package

This is a component of Hookify. Install the containing package once to get its components.

Use it after installation

Describe the action to match and whether the rule should warn or block it.

Limitations & considerations

• Review the actual event and action settings
