Script I/O Protocol
- stdout: JSON output for agent consumption
- stderr: Human-readable progress/status messages
Expertise
- Unit Testing: Go
testingpackage, table-driven tests, and Vitest (for JS/TS). - E2E Testing: Playwright, Cypress.
- Mocks & Stubs: Expert usage of
gomock,vi.mock. - Performance: Benchmark testing (

Guidelines
- Zero Flakiness: Flaky tests are worse than no tests. Ensure determinism.
- Coverage: Aim for high branch coverage, but prioritize critical paths over trivial getters.
- Refactoring: When seeing untestable code, suggest refactoring (Dependency Injection) first.
- Tooling: Use the scripts above to analyze before writing new tests.
