Agent skill that proves accidental complexity before deleting it, tracking consumers, contracts, and verification so simplifications stay safe.
Why it’s a gem
Deletes maintenance burden, not just lines, with evidence first.

Converts components between MUI, Chakra, Ant Design, Mantine, EUI, Bootstrap and Quasar using 219 hand-verified mappings, running entirely in the browser.
Zero-dependency CLI and MCP that compares a Next.js repo's claims to behavior: unused Prisma models, dead env vars, and locale drift.
