The instructions your model reads when the skill loads.
Guided specification creation through 9 structured phases.
Create a complete, implementation-ready specification document by walking through 9 phases: discovery, context gathering, requirements, constraints, architecture, interfaces, error handling, testing strategy, and final assembly. Supports three spec types (library, feature, change) with type-specific templates. Produces YAML test data alongside the spec for immediate TDD usage.
# Interactive guided mode (asks questions at each phase)
/create-spec --type feature
# Autonomous mode with initial description
/create-spec --type library --description "HTTP client with retry and circuit breaking"
# Create a change spec for an existing system
/create-spec --type change --scope lib/auth/ --description "Add OAuth2 PKCE flow"
# Resume an in-progress spec
/create-spec --resume
# Generate only the test data from an existing spec
/create-spec --tests-only --from specs/auth-spec.md
