WHAT IT DOES

What metaharness_gepa does on Claude Flow

AI agents call metaharness_gepa as a supporting operation in Claude Flow workflows.

RISK

Why metaharness_gepa is rated Low

The description is incomplete/truncated, making it impossible to determine what this tool actually does. 'GEPA genome operations' could refer to genetic algorithm or evolutionary programming abstractions, but without more context it's unclear if this reads, writes, executes, or destroys data. Confidence is very low due to the uninformative description.

From the tool's definition 'GEPA genome operations from the' - description is truncated and uninformative; tool name 'metaharness_gepa' provides no clear operational semantics

RECOMMENDED RULE

The rule that runs metaharness_gepa safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Claude Flow, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For metaharness_gepa, this is the rule to start with:

metaharness_gepa Rate-limited

metaharness_gepa gets a rate cap, and everything else on the server is denied unless you say otherwise.
