Prevention Rules

Manage prevention rules that are auto-generated from repeated failure patterns.

When to use

• Reviewing current active prevention rules for the project
• Checking if a specific action is blocked by a prevention rule
• Understanding why an action was blocked
• Generating new prevention rules from observed patterns

How it works

Use the prevention_rules MCP tool to:

1. List rules — View all active prevention rules with their match patterns and corrective actions.
2. Check rules — Test if a specific action matches any prevention rule before execution.
3. Review rule history — See which feedback events led to a rule's promotion.

Example

Check prevention rules for "npm publish without running tests" to see if this action is blocked.

Prevention rules are auto-promoted when the same failure pattern appears multiple times in captured feedback. Each rule includes the original failure context and a corrective action.
