+# Duron Project Rules
+
+This is the **Duron** monorepo - a type-safe job queue system for Node.js and Bun.
+
+## Primary Context
+
+**Always reference `CLAUDE.md` at the project root for comprehensive project documentation.**
+
+The CLAUDE.md file contains:
+- Project overview and architecture
+- Monorepo structure and package details
+- Code patterns and examples
+- Development workflow and commands
+- Testing and linting guidelines
+- Key files reference
+
+## Quick Reference
+
+### Runtime
+
+**Use Bun exclusively.** Never use Node.js, npm, pnpm, yarn, or vite (except for docs).
+
+```bash
+bun install          # Install dependencies
+bun <file>           # Run a file
+bun test             # Run tests
+bun run <script>     # Run scripts
+```
+
+### Packages
+
+| Package | Description |
+|---------|-------------|
+| `duron` | Core library (client, actions, server, adapters) |
+| `duron-dashboard` | React dashboard UI |
+| `docs` | Documentation site |
+| `examples` | Example implementations |
+
+### Key Commands
+
+```bash
+bun run lint:fix         # Fix linting issues
+bun test                  # Run tests
+bun run dev:dashboard     # Dashboard dev server
+bun run typecheck         # Type checking
+```
+
+### Code Style
+
+- Use Zod for schema validation
+- Use `defineAction()` for creating actions
+- Use `ctx.step()` for retryable operations
+- Use `NonRetriableError` for permanent failures
+- Use pino logger (not console.log)
+
