Ensures tech-stack-aware behavior during workflows. Auto-activates when stack profile rules exist in .claude/rules/stack-*.md. Activates during /arch:init, /context:load, /context:refresh, /deliver, /discern, /diagnose, and /handoff.
Enforces code quality standards when writing or editing code. Use when implementing features, fixing bugs, or refactoring. Ensures error handling, no hardcoded values, proper patterns, and security considerations.
Enforces project patterns and architecture conventions. Use when designing systems, implementing features, or reviewing code structure. Ensures consistency with established patterns.
Structured root cause investigation when tests fail unexpectedly or fixes don't resolve the issue. Use when a test fails that you expected to pass, when a previous fix attempt didn't work, or when an error occurs during implementation.
Enforces test-driven development with Red-Green-Refactor cycle. Use when writing new code, implementing features, fixing bugs, or when tests are mentioned. Ensures tests are written before implementation.
Ensures brand-consistent behavior during workflows. Auto-activates when brand guide exists and "brand", "brand spec", "design tokens", "brand consistent", or "visual identity" are mentioned. Activates during /brand, /brand:image, /brand:tokens, /design, /deliver, /discern, /handoff, /context:load, and /context:refresh.
Ensures spec-driven behavior during all workflows. Use when loading context, discussing project structure, starting features, or when "spec", "specification", "acceptance criteria", or "bootstrap" are mentioned. Activates during /context:load, /context:refresh, /spec:init, /define, /design, /deliver, /discern, /handoff, /done, and /discover.
Ensures ADR and C4 diagram behaviors during all workflows. Use when loading context, discussing architecture, creating designs, or when "ADR", "architecture decision", "C4", "coupling", "cohesion", or "boundary" are mentioned. Activates during /arch:init, /context:load, /context:refresh, /spec:init, /define, /design, /deliver, /discern, /handoff, /diagnose, and /discover.
