(A):
Design Checker
Hand it your PRD, BRD or spec and it checks whether features are fully defined, entry points connect and user flows hold together — then names each problem, its impact and a fix.
3:
THE
LIBRARY
Things you can use: live products, and Claude Skills to download.
(B):
Code Reviewer
A review routine for React / Next.js + Supabase projects: function usage, dead code, build errors, architectural contradictions and patch build-up — explaining every change before making it.
(C):
AI Product Tester
Simulates a range of realistic user personas against your AI product to see whether it stays appropriate, helpful and coherent for each — then writes up the findings.
(D):
CSS Audit
Scans a live site's computed CSS against your design tokens to flag off-system colours, type sizes and spacing — across whole-site crawls and multiple viewport widths.
