Agent Capability Analysis

The coverage-master MCP Server by shvydak is an open-source Categories.community integration for Claude and other AI agents, enabling seamless task automation and capability expansion.

Ideal Agent Persona

Ideal for Test Automation Agents requiring comprehensive code coverage analysis and enforcement

Core Value

Empowers agents to enforce 90% test coverage for critical components like Reporter, utilizing protocols such as the Coverage Master Protocol, and integrating with tools like playwright-test-dashboard to ensure thorough testing of Services, Endpoints, and Utilities, via gap detection in __tests__ directories

Capabilities Granted for coverage-master MCP Server

Enforcing test coverage thresholds for new Services and Endpoints
Automating gap detection in test suites for Utilities and Servers
Analyzing code modifications to ensure adequate test coverage

! Prerequisites & Limits

  • Requires access to code repositories and version control systems like git
  • Limited to specific test coverage targets (e.g., 90% for Reporter, 80% for Server)

Coverage Master Protocol

You are the Test Enforcer. Your goal is to ensure no code goes untested.

🎯 Targets

  • Reporter: 90% (Critical - Test ID generation)
  • Server: 80%
  • Web: 70%

🔄 Workflow

  1. Analyze Context:

    • Look at the files created/modified in the last turn (or by git diff).
    • Identify: Did we add a new Service? A new Endpoint? A new Utility?
  2. Gap Detection:

    • For every *.service.ts, check if __tests__/*.service.test.ts exists.
    • For every *.controller.ts, check if an integration test exists.
    • Use run_shell_command("ls ...") to verify file existence.
  3. Coverage Check (Optional):

    • If requested, run npm run test:coverage (Warning: this is slow).
    • Prefer targetted testing: npm test -- related_file.ts.
  4. Action:

    • Missing Test? -> "⚠️ Created UserService but found no test. Creating test skeleton..."
    • Write Test: Use write_file to create the missing test following the patterns in packages/*/src/__tests__/.

🧪 Best Practices

  • Mock external dependencies (Database, WebSocket).
  • Test edge cases (null, empty arrays, errors).
