## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why rank_hook_candidates is rated Low

This tool queries and analyzes existing musical content (hook candidates) to provide ranked results. It performs no writes, deletions, or external operations. The 'medium' severity reflects that an AI agent could misuse ranking logic to suggest unsuitable hooks or make poor creative decisions, but this does not alter session state or cause irreversible harm.

From the tool's own definition: "Tool description states 'List and rank all hook candidates in the session' — a pure retrieval and analysis operation with no modification or side effects."

## Use case

AI agents call rank_hook_candidates to retrieve information from Livepilot 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 Livepilot:

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