design
by howells
Create distinctive, non-generic UI designs with aesthetic direction and ASCII wireframes. Use when asked to "design the UI", "create a layout", "wireframe this", or when building UI that should be memorable rather than generic. Avoids AI slop patterns.
implement
by howells
Plan and execute feature implementation with TDD and continuous quality checks. Use when asked to "implement this", "build this feature", "execute the plan", or after /arc:ideate has created a design doc. Creates implementation plan if needed, then executes task-by-task with build agents.
review
by howells
Run expert review on a plan with parallel reviewer agents. Presents findings as Socratic questions. Use when asked to "review the plan", "get feedback on the design", "check this approach", or before implementation to validate architectural decisions. Optional argument: reviewer name (e.g., /arc:review daniel-product-engineer to use a specific reviewer)
letsgo
by howells

detail
by howells
Internal skill for creating implementation plans. Invoked by /arc:implement, not directly. Creates detailed plans with exact file paths, test code, and TDD cycles.
ideate
by howells
