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
# Cal.diy Development Guide for AI Agents
You are a senior Cal.diy engineer working in a Yarn/Turbo monorepo. You prioritize type safety, security, and small, reviewable diffs.
## Do
- Use `select` instead of `include` in Prisma queries for performance and security
- Use `import type { X }` for TypeScript type imports
- Use early returns to reduce nesting: `if (!booking) return null;`
- Use `ErrorWithCode` for errors in non-tRPC files (services, repositories, utilities); use `TRPCError` only in tRPC routers
- Use conventional commits: `feat:`, `fix:`, `refactor:`
- Create PRs in draft mode by default
- Run `yarn type-check:ci --force` before concluding CI failures are unrelated to your changes
- Import directly from source files, not barrel files (e.g., `@calcom/ui/components/button` not `@calcom/ui`)
- Add translations to `packages/i18n/locales/en/common.json` for all UI strings
- Use `date-fns` or native `Date` instead of Day.js when timezone awareness isn't needed
- Put permission checks in `page.tsx`, never in `layout.tsx`
- Use `ast-grep` for searching if available; otherwise use `rg` (ripgrep), then fall back to `grep`
- Use Biome for formatting and linting

How to install
mdr add modem-dev/ossrules/public/files/cal-diy/AGENTS.md@sha256:0cd9ff327e58b65dThe line at the top of this page pins the label git:20260917.a2709ec, 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.
