## Why hn_item is rated Low

This tool retrieves a single item from Hacker News using its ID. It performs a read-only query operation with no side effects, no data modification, no execution of external code, and no financial implications. The only potential risk is information disclosure, which is minimal since Hacker News data is public. Low severity due to no destructive capability and limited blast radius.

From the tool's own definition: "Tool name 'hn_item' and description 'Get a specific Hacker News item by ID' indicate retrieval of existing data without modification or deletion."

## Use case

AI agents call hn_item to retrieve information from UnClick 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)

```json
{
  "version": "1",

  "tools": {
    "hn_item": {}
  }
}
