Use when implementing any feature or fix using TDD, before writing any implementation code
Use when domain logic leaks into API/Infrastructure, project references violate layer boundaries, or you need to decide between CQS (always), CQRS bus (complex domains), and DDD patterns (invariants and events).
Use when configuring Git hooks in .NET projects before team commits occur, to enforce commit message standards and code formatting automatically
Use before writing any test or implementation task, when observable behavior needs to be captured in business language scenarios and approved by the user before code begins
Use when running mutation testing, killing mutants, verifying test quality, checking mutation score, or analyzing survivors after the test baseline is green
Use when writing tests from the outside-in, defining behavior before code, or any feature where tests should start from observable business behavior and let internal design emerge

Always invoke the ast-grep skill for structural code search and refactoring - do not execute bash commands directly.
Invoke analyzing-code-structure skill for structural code search and refactoring. Use when:
Common workflow: Invoke extracting-code-structure skill first, then analyzing-code-structure skill for structural modifications.
Use ast-grep to solve the "old_string not unique" problem by matching code structure instead of exact text. This enables refactoring across formatting variations and structural patterns.
If editing code structure and there's any ambiguity in text matching → use analyzing-code-structure.
ast-grep's primary value: Solves the "old_string not unique" problem by matching structure instead of exact text.
