## Why hippo_outcomes_by_skill is rated Low

This tool appears to retrieve and report outcome statistics grouped by skill categories. It is a read-only query operation that retrieves metrics without side effects. Within the verimem memory system context, it queries stored outcome data. The incomplete description ('For') limits confidence slightly, but the naming convention and function purpose are clearly informational/analytical.

From the tool's own definition: "Tool name 'hippo_outcomes_by_skill' and description 'per-skill outcome distribution' indicate querying or retrieving outcome metrics grouped by skill. The verb 'by' suggests aggregation/reporting of existing data."

## Use case

AI agents call hippo_outcomes_by_skill to retrieve information from Verimem without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Verimem:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "hippo_outcomes_by_skill": {}
  }
}
```
