WHAT IT DOES

What hooks_init does on Ruflo

AI agents use hooks_init to create or update resources in Ruflo — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Ruflo environment.

WHY IT NEEDS A POLICY

Why hooks_init needs a policy

This tool creates or modifies configuration files (settings.json) in the project to set up hooks. It's a Write operation as it creates new configuration. Severity is medium because hooks could influence behavior of other tools/agents in the swarm system, but it's not directly destructive or executable. Confidence is slightly reduced because the description is truncated and incomplete.

From the tool's definition Initialize hooks in project with .claude/settings.json
