154### Code Standards
155- **TypeScript required** with strict interfaces
156- **Functional programming** preferred over classes
157- **No external images** - use emojis, Unicode symbols, or icon fonts
158- **Error handling**: Let errors bubble up with context rather than catching/logging
160- **Prefer official SDKs** over writing API calls directly
161- **Comments**: Only explain complex logic, avoid commenting obvious operations
162- **Complete solutions**: Provide functional implementations, not skeleton code

164### Hono Framework Specifics
187### HTTP Triggers (Current Implementation)
188```ts
189export default async function (req: Request) {
190  return new Response("Hello World");
191}
194### Cron Triggers (For Scheduled Tasks)
195```ts
196export default async function () {
197  // Could be used for weather data caching or alerts
198}
201### Email Triggers (For Email Processing)
202```ts
203export default async function (email: Email) {
204  // Could process weather alert subscription emails
205}
206```
