delegation_retry · Musubix MCP: Risk & Policy

WHAT IT DOES

What delegation_retry does on Musubix

AI agents invoke delegation_retry to trigger actions in Musubix. 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 delegation_retry needs a policy

This tool re-triggers a delegation operation that previously failed, causing an external operation to be re-executed. 'Retry a failed delegation' indicates it re-dispatches or re-runs an action, placing it in the Execute category.

From the tool's definition Retry a failed delegation with optional feedback. Implements exponential backoff.

delegation_retry Rate-limited

delegation_retry stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
