atoms_get_coverage

Analyze test coverage across requirements in a project. Identifies requirements that lack linked test cases, helping you find coverage gaps. In capable MCP hosts, this tool renders an interactive coverage heatmap via the MCP App protocol.

Parameters

Example Response

{
  "status": "success",
  "data": {
    "covered": 38,
    "uncovered": 7,
    "total": 45,
    "coverage_percent": 84.4,
    "uncovered_items": [
      {
        "id": "REQ-012",
        "title": "System shall support offline mode",
        "type": "requirement",
        "domains": ["reliability"],
        "level": "System"
      },
      {
        "id": "REQ-034",
        "title": "Data export shall include CSV format",
        "type": "requirement",
        "domains": ["data"],
        "level": "Subsystem"
      }
    ]
  }
}

Notes

• This tool is read-only and does not modify any data (readOnlyHint: true).
• A requirement is considered "covered" when at least one test case is linked to it via a verifies relationship.
• Use the domain and level filters to analyze coverage for a specific slice of the project, for example all safety-domain system-level requirements.
• The uncovered_items array lists every requirement that has zero linked test cases, making it straightforward to prioritize test authoring.
• In MCP hosts that support the App protocol, this tool displays an interactive coverage heatmap alongside the JSON response.
