# spine_clean

Use this to run Spine CLI animation clean up with -m on a project or supported input. Do not use it to delete files, rewrite project internals directly, export assets, pack textures, or automate the editor UI.

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

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

## Why spine_clean is rated High

The tool runs a CLI command (Spine CLI with -m flag) which constitutes executing an external process. The description explicitly says 'Do not use it to delete files' suggesting it doesn't irreversibly destroy data, but running CLI cleanup operations can modify project state. This puts it in the Execute category as it triggers an external CLI operation whose effects depend on the input project.

From the tool's own definition: "'run Spine CLI animation clean up with -m on a project' — executes the Spine CLI with a flag against a project file"

## Use case

AI agents invoke spine_clean to trigger actions in Spine. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Spine:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "spine_clean": {
      "limits": [
        {
          "counter": "spine_clean_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
