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

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

  "method": "tools/call",
  "params": {
    "name": "test_stop_watch",
    "arguments": {}

## Why test_stop_watch is rated Low

The description is empty and the name only suggests a stopwatch-related test utility. Without any description, it is unclear what this tool does. Based on the name alone, it likely reads or displays elapsed time, but this is speculative. Confidence is very low due to lack of evidence.

From the tool's own definition: "Tool name 'test_stop_watch' and empty description provide no actionable information about what the tool does."

## Use case

AI agents call test_stop_watch as a supporting operation in Looking Glass workflows.

## Recommended policy (PolicyLayer)
