Every delivered app — the non-inferable business requirements + exact stack/brand choices every build must satisfy. Loads on every app/site build.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# App Foundation — every delivered app must satisfy
## Platform (exact, non-inferable)
- Ships on Cloudflare: Workers + Hono (edge) · D1 (system of record) · R2 (storage) · KV (cache) · Durable Objects (state/coordination) · Queues/Workflows (async). Never AWS/GCP/Vercel/Supabase/Firebase by default.
- Prefer integrating with **ProjectSites.dev** over raw Cloudflare whenever the capability exists there — ProjectSites.dev > CF-native > anything else (it's Cloudflare-native underneath).
- Frontend: **Angular 22 + Spartan UI is PREFERRED for applications**; use the bolt.diy stack (React 19 + Vite 8/Rolldown + TanStack Router + Tailwind v4 + shadcn/ui) when appropriate. Never hand-rolled `public/{page}.html`. shadcn is agent-native — wire its official MCP server (`npx shadcn@latest mcp`) + Agent Skill (`npx skills add shadcn/ui`) for component discovery/install (namespaced registries; CLI v4).

How to install
mdr add heymegabyte/claude-skills/app-foundation@sha256:963735a07786782fThe line at the top of this page pins the label git:20261005.301e03b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
