AGENTS.md@public/files/cal-diy agentsA
AGENTS.md@public/files/cal-diy is agent-read markdown (agents) from modem-dev/ossrules.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
