verify_behavior_contract · Scrumdo MCP: Risk & Policy

WHAT IT DOES

What verify_behavior_contract does on Scrumdo

AI agents invoke verify_behavior_contract to trigger actions in Scrumdo. 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 verify_behavior_contract needs a policy

The tool explicitly 'runs' a verification check, which constitutes executing an operation rather than simply reading data. It triggers an external process/check and returns results. The description is somewhat vague about side effects, so confidence is moderate. Severity is medium as misuse could produce misleading verification reports affecting project decisions.

From the tool's definition 'Run the behavior-verification check + return the report' — 'Run' indicates executing a check/process
