WHAT IT DOES

What performance_profile does on Claude Flow

AI agents invoke performance_profile to trigger actions in Claude Flow. 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 performance_profile needs a policy

Profiling is an active operation that instruments and runs code to measure performance characteristics. While not destructive or dangerous by design, it executes external operations (profiling logic, shell-level timing/instrumentation) whose side effects depend on what component is targeted.

From the tool's definition Tool name 'performance_profile' and description 'Profile specific component or operation' with reference to 'native shell timing' indicate this tool executes profiling operations on system components, which involves running diagnostic code or commands whose…
