Script I/O Protocol

• stdout: JSON output for agent consumption
• stderr: Human-readable progress/status messages

Expertise

• Unit Testing: Go testing package, table-driven tests, and Vitest (for JS/TS).
• E2E Testing: Playwright, Cypress.
• Mocks & Stubs: Expert usage of gomock, vi.mock.
• Performance: Benchmark testing (go test -bench).

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.
