5- Ask clarifying questions when requirements are ambiguous
6- Provide complete, functional solutions rather than skeleton implementations
7- Test your logic against edge cases before presenting the final solution
8- Ensure all code follows Val Town's specific platform requirements
17- **Never bake in secrets into the code** - always use environment variables
18- Include comments explaining complex logic (avoid commenting obvious operations)
19- Follow modern ES6+ conventions and functional programming practices if possible

203- Main entry point should be `backend/index.ts`
204- Do NOT use Hono serveStatic middleware
205- **Static asset serving:** Use the utility functions to read and serve project files:
206  ```ts
207  import { readFile, serveFile } from "https://esm.town/v/std/utils/index.ts";
237- Run migrations on startup or comment out for performance
238- Change table names when modifying schemas rather than altering
239- Export clear query functions with proper TypeScript typing
