Red-green-refactor development methodology requiring verified test coverage. Use for feature implementation, bugfixes, refactoring, or any behavior changes where tests must prove correctness.
TDD workflow guide. Use PROACTIVELY when writing new features or fixing bugs. Enforces Red-Green-Refactor cycle and prevents testing anti-patterns.
Use when writing any new code, adding features, or fixing bugs that require code changes. Enforces strict RED-GREEN-REFACTOR cycle with no production code without a failing test first. Triggers: new feature implementation, bug fix, refactoring existing code, adding behavior to existing modules.
Guides strict Test-Driven Development (TDD) using the Red-Green-Refactor cycle. Ensures no production code is written without a prior failing test. Use this skill when implementing new features, fixing bugs, or refactoring code to ensure high test coverage and design quality. Triggers on phrases like 'TDD', 'write tests first', 'test-driven', 'red-green-refactor', 'watch it fail', 'test first', or 'behavior driven'.
Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first
Red-green-refactor discipline. Use when writing new functionality.
Use when implementing any feature or bugfix, before writing implementation code
Go testing patterns and methodology: table-driven tests, t.Run subtests, t.Helper helpers, mocking interfaces, benchmarks, race detection, and synctest. Use when writing new Go tests, modifying existing tests, adding coverage, fixing failing tests, writing benchmarks, or creating mocks. Triggered by "go test", "_test.go", "table-driven", "t.Run", "benchmark", "mock", "race detection", "test coverage". Do NOT use for non-Go testing (use test-driven-development instead), debugging test failures (use systematic-debugging), or general Go development without test focus (use golang-general-engineer directly).
Systematic detection and prioritization of neglected code quality issues: stale TODOs, unused imports, deprecated functions, high complexity, dead code. Use when user requests "code cleanup", "find TODOs", "technical debt scan", or "quality of life fixes". Do NOT use for bug fixing (use systematic-debugging), feature work (use test-driven-development), or formatting-only (use code-linting).
Identify and fix common testing mistakes across unit, integration, and E2E test suites. Use when tests are flaky, brittle, over-mocked, order-dependent, slow, poorly named, or providing false confidence. Use for "test smell", "fragile test", "flaky test", "over-mocking", "test anti-pattern", or "skipped tests". Do NOT use for writing new tests from scratch (use test-driven-development), refactoring architecture (use systematic-refactoring), or performance profiling without a specific test quality symptom.
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.
Use when creating new skills, editing existing skills, or verifying skills work before deployment
