Show HN: AI tool that brutally roasts your AI agent ideas

I built whycantwehaveanagentforthis.com — submit any problem and get a structured analysis of whether an AI agent could solve it. The output includes a creative agent name, feasibility verdict, real competitor analysis (actual products with URLs), a kill prediction (which big tech company makes this obsolete, when), build estimate, and a savage one-liner. Built with Next.js + Claude API (Haiku). Runs on ~$5/day. Rate limited with Upstash Redis (7 layers). The prompt engineering to get accurate, non-hallucinated competitor analysis was the hardest part. Free, no signup. Feedback welcome — especially on AI response quality.
