-## Key Commands (run from repo root)
+## Key Commands
 
-| Task | Command |
-|------|---------|
-| Lint (check only) | `bun run lint:check` |
-| Lint (auto-fix) | `bun run lint` |
-| Format (check) | `bun run format:check` |
-| Format (auto-fix) | `bun run format` |
-| Tests | `bun run test` |
-| Type check | `bun run type-check` |
-| Dev (full) | `bun run dev:full` |
-| DB migrations | `cd packages/db && bunx drizzle-kit migrate --config=./drizzle.config.ts` |
+- **Lint**: `bun run lint:check` (biome check, no auto-fix) or `bun run lint` (with auto-fix)
+- **Format**: `bun run format:check` or `bun run format` (with auto-fix)
+- **Test**: `bun run test` (runs vitest via turbo across packages)
+- **Type-check**: `bun run type-check` (runs tsc --noEmit via turbo)
+- **Dev**: `bun run dev:full` from root or `apps/sim` (starts Next.js + Socket.IO)
+
+## Database
+
+- PostgreSQL with pgvector extension, connection via `DATABASE_URL` in `.env` files
+- Migrations: `cd packages/db && bunx drizzle-kit migrate --config=./drizzle.config.ts`
+- Schema push (no migration files): `cd packages/db && bunx drizzle-kit push --config=./drizzle.config.ts`
+- Two `.env` files are needed: `apps/sim/.env` and `packages/db/.env` (both need `DATABASE_URL`)
+
+## Testing
+
+- Framework: Vitest (config at `apps/sim/vitest.config.ts`)
+- Use `@sim/testing` mocks/factories (see `.cursor/rules/sim-testing.mdc`)
+- Tests run in parallel with thread pool
+- Run specific test: `cd apps/sim && bunx vitest run path/to/test.test.ts`
 
 ## Important Notes
 
-- **Package manager**: Always use `bun` / `bunx`, never `npm` / `npx`.
-- **Linter**: Biome (not ESLint). Config at `/workspace/biome.json`.
-- **Testing**: Vitest. Test files co-located as `*.test.ts`. Use `@sim/testing` mocks.
-- **Pre-commit**: Husky runs `bunx lint-staged` which runs `biome check --write`.
-- **Database**: PostgreSQL 17 with pgvector extension. Drizzle ORM for schema/migrations.
-- **Env files**: `apps/sim/.env` and `packages/db/.env` must both have `DATABASE_URL`.
-- **Docs type-check**: Requires `fumadocs-mdx` to be run first (generates `.source/` directory). This runs as `postinstall` in `apps/docs`.
-- **Redis**: Optional. Socket server falls back to in-memory mode without `REDIS_URL`.
-- **Auth**: Better Auth. Social providers (GitHub, Google) need `clientId`/`clientSecret` in env. Warnings about missing social provider config are expected in dev.
+- Package manager is **bun** (not npm/pnpm). Use `bun` and `bunx` commands.
+- The docs app requires `fumadocs-mdx` generation before type-check: `cd apps/docs && bunx fumadocs-mdx`
+- Pre-commit hook runs `bunx lint-staged` which applies biome check with auto-fix
+- Social provider warnings (GitHub/Google missing clientId) during startup are expected in local dev
+- Redis warnings ("REDIS_URL not configured") are expected - app runs in single-pod mode locally
