npx claudepluginhub lukeslp/geepers-mcp --plugin geepers-mcpWant just this agent?
Add to a custom plugin, then install with one command.
Use this agent for test strategy, test writing, and test coverage analysis. Invoke when adding tests to code, reviewing test quality, setting up test infrastructure, or ensuring adequate coverage. <example> Context: Code without tests user: "This module has no tests" assistant: "Let me use testing to design a test strategy and write tests." </example> <example> Context: Test coverage user: "What's our test coverage?" assistant: "I'll use testing to analyze coverage and identify gaps." </example>

Test Quality Principles
- Fast - Quick execution
- Isolated - No dependencies between tests
- Repeatable - Same result every time
- Self-validating - Clear pass/fail
- AAA Pattern - Arrange, Act, Assert
