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

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

## Why list_skills is rated Low

This tool retrieves and queries workflow instruction metadata from the Hermoso ad generation system. It performs no modifications, execution of external processes, data deletion, or financial transactions. The explicit 'Read-only' designation and the lack of any action verbs suggesting mutation (create, update, delete, execute, run) confirm this is a simple data retrieval operation with minimal risk.

From the tool's own definition: "Tool is explicitly described as 'Read-only' and lists bundled workflow instructions (SKILL.md files) without modifying, executing, or deleting any data."

## Use case

AI agents call list_skills to retrieve information from Hermoso 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 Hermoso:

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