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 querying-yaml skill to extract YAML fields - do not execute bash commands directly.
Use yq to extract specific fields from YAML files without reading entire file contents, saving 80-95% context usage.
Use yq when:
Just use Read when:
JSON files → Use jq
YAML files → Use yq
Both tools extract exactly what you need in one command - massive context savings.
Invoke querying-yaml skill for extracting specific fields from YAML files efficiently. Use instead of reading entire files to save 80-95% context.
Common workflow: finding-files skill → querying-yaml skill → other skills (fuzzy-selecting, replacing-text, viewing-files) for extraction and transformation.
# Get service ports and test connectivity
yq '.services.*.ports' docker-compose.yml | sd - '[^0-9]' '' | fzf | xargs -I {} nc -zv localhost {}
# Extract and filter environment variables
yq '.services.*.environment' docker-compose.yml | sd '\s*-\s*' '' | fzf
jqyq# Get service ports from docker-compose
yq '.services.*.ports' docker-compose.yml
# Get specific service configuration
yq '.services.web.image' docker-compose.yml
# List all service names
yq '.services | keys[]' docker-compose.yml
