prd-help · v1.1
Lean builder
Use whenever you write or change code in this project. Keeps the build to what PRD.md asks for: the smallest change that works, with no extra features, libraries or abstractions.
Resource library
Skills
Skills are short instructions your coding agent loads when they fit the task. Every prd-help pack carries these, in .agents/skills for Codex, OpenCode and Cursor and in .claude/skills for Claude Code. Each card opens the full SKILL.md on prd-help.
Ours, in every pack
prd-help · v1.1
Prove before tick

obra/superpowers
systematic-debugging
Find the root cause before fixing anything, in four phases. Its one script only runs the project's own tests.

prd-help, rules by Vercel
web-interface-review
Reviews UI code for accessibility, focus, forms and layout. Vercel's rules are frozen into the skill, so it downloads nothing.
Matched to your stack
prd-help reads the Stack and Deployment sections of your PRD and adds up to 6 of these, by a fixed list: Postgres, Supabase or Neon → supabase-postgres-best-practices; Prisma → prisma-client-api; MongoDB → mongodb-schema-design, mongodb-query-optimizer; Expo or React Native → react-navigation, react-native-testing; Sign in with Google → sign-in-with-google-web; PostHog → instrument-error-tracking; Cloudflare Agents → agents-sdk; Firebase → firestore-rules-creation; Redis → redis-core; Cloudflare → workers-best-practices; Resend → email-best-practices, react-email.
