by campbellmcgregor
Expert graphic, UI/UX designer for creating mockups, wireframes, and visual designs. Use when user needs help with designing interfaces, creating mockups, prototyping layouts, visual design feedback, design systems, brand identity, choosing colors/typography, or creating graphics. Triggers include "design," "mockup," "wireframe," "UI," "UX," "interface," "visual," "brand," or "prototype."
first-principle-thinking
by campbellmcgregor
Expert methodology for breaking down complex problems into fundamental truths and rebuilding solutions from the ground up. Use when users need breakthrough innovation (not incremental improvement), question industry assumptions, face seemingly impossible problems, want to understand root causes, ask "why does this have to be this way", "rethink from scratch", "reimagine this", request analysis "from first principles", want to challenge conventional wisdom, question everything, or need to deconstruct problems to their core elements. Ideal for strategic decisions, innovation challenges, cost optimization, and escaping local optima.

root-cause-tracing
by liauw-media
"Use when symptoms don't reveal the cause. Trace backward through call chains to find where problems originate. Follow: Observe symptom → Find immediate cause → Identify caller → Keep tracing → Locate trigger."
testing-skills-with-subagents
by liauw-media
"Use to validate process documentation. Apply TDD to skill writing: RED (run without skill, document failures) → GREEN (write skill) → REFACTOR (close loopholes). Test under pressure: time constraints, sunk cost, exhaustion, authority."
writing-skills
by liauw-media
"Use when creating reusable process documentation. Apply TDD: baseline without skill → document failures → write skill → test → iterate. Four types: Discipline, Technique, Pattern, Reference. Iron Law: No skill without failing test first."
testing-anti-patterns
by liauw-media
"Use to avoid critical testing mistakes. Five Iron Laws: Never test mock behavior, Never add test-only methods, Never mock without understanding, Always integration test, Always test error paths."
sharing-skills
by liauw-media
"Use when contributing skills back to the community. Follow git workflow: sync upstream → create branch → develop skill → test with writing-skills → commit → push → PR. One skill per PR."
