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

122## Val Town Utility Functions
123
124Val Town provides several utility functions to help with common project tasks.

226- Hono is the recommended API framework
227- Main entry point should be `backend/index.ts`
228- **Static asset serving:** Use the utility functions to read and serve project files:
229  ```ts
230  import { readFile, serveFile } from "https://esm.town/v/std/utils@85-main/index.ts";
260- Run migrations on startup or comment out for performance
261- Change table names when modifying schemas rather than altering
262- Export clear query functions with proper TypeScript typing
