## Why add_artifact is rated Medium

This tool creates or modifies task metadata by attaching file artifacts. It is Write-category because it adds/updates reversible data structures (artifact attachments) without executing code or deleting data. Severity is medium because attachment operations could pollute task records or attach sensitive files if misused by an agent, but the damage is reversible and scoped to metadata/references.

From the tool's own definition: "Tool description states 'Attach a local file as artifact' — the verb 'attach' indicates modification of a task/project/plan/run entity by adding new file metadata/references."

## Use case

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

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "add_artifact": {
      "limits": [
        {
          "counter": "add_artifact_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
