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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "generate_skeleton",
    "arguments": {}
  }

```

## Why generate_skeleton is rated Medium

This tool creates new XML file structures but does not execute arbitrary code, delete data, or modify financial systems. It is reversible (generated skeletons can be replaced or deleted by the user) and has no destructive capability.

From the tool's own definition: "Tool name 'generate_skeleton' and description state it 'Generate[s] canonical deterministic TwinCAT XML skeleton for a file type' — this creates or scaffolds new code/data structures (XML files) for industrial automation projects."

## Use case

AI agents use generate_skeleton to create or update resources in TwinCAT Validator MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TwinCAT Validator MCP Server environment.

## Recommended policy (PolicyLayer)
