hooks_model-route · Ruflo MCP: Risk & Policy

WHAT IT DOES

What hooks_model-route does on Ruflo

AI agents invoke hooks_model-route to trigger actions in Ruflo. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why hooks_model-route needs a policy

This tool triggers execution of tasks by routing them to AI models and invoking native Bash hooks via Claude Code. It doesn't merely read or write data — it dispatches work to external AI systems and executes hooks, which can have wide-ranging side effects depending on the task content. The Bash hook integration especially elevates severity since arbitrary commands could be triggered downstream.

From the tool's definition "Route task to optimal Claude model (haiku/sonnet/opus) based on complexity" and "native Bash hooks (via Claude Code")
