Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Claude's capabilities with specialized knowledge, workflows, or tool integrations.

Table-driven test pattern for writing clean, maintainable, and comprehensive tests. Separate test data (table entries) from test logic to eliminate copy-paste duplication. Use when: (1) writing Go tests with multiple input/output variations, (2) testing pure functions with various combinations, (3) refactoring duplicated test code, (4) adding edge cases and boundary conditions to existing tests, (5) implementing TDD test scenarios that share the same assertion structure. Covers Go-specific patterns (t.Run subtests, parallel execution, cmp.Diff) and language-agnostic principles applicable to any parameterized testing.

Test-Driven Development workflow based on t_wada and Kent Beck's Canon TDD. Enforce the List-Red-Green-Refactor cycle for AI agent development. Use when: (1) implementing features with TDD, (2) AI agent is delegated to write code with tests, (3) user requests TDD or test-first development, (4) ensuring correctness of AI-generated code through test-driven discipline.
