Review existing agentic code, designs, or plans through the lens of the 12 canonical antipatterns. Diagnose what's likely to fail in production. Use whenever the user asks you to review their agent code, asks "what's wrong with this design," is debugging mysterious failures, or wants a second opinion on an architecture. Also use proactively when you notice any of the 12 antipatterns in a conversation, even if the user didn't ask for review.
