 * Prefer implementing functionality in existing files unless it is a new logical component. Avoid creating many small files.
 * Avoid using functions that panic like `unwrap()`, instead use mechanisms like `?` to propagate errors.
 * Be careful with operations like indexing which may panic if the indexes are out of bounds.
+* Never silently discard errors with `let _ =` on fallible operations. Always handle errors appropriately:
+  - Propagate errors with `?` when the calling function should handle them
+  - Use `.log_err()` or similar when you need to ignore errors but want visibility
+  - Use explicit error handling with `match` or `if let Err(...)` when you need custom logic
+  - Example: avoid `let _ = client.request(...).await?;` - use `client.request(...).await?;` instead
+* When implementing async operations that may fail, ensure errors propagate to the UI layer so users get meaningful feedback.

 GPUI has had some changes to its APIs. Always write code using the new APIs:

 * `spawn` methods now take async closures (`AsyncFn`), and so should be called like `cx.spawn(async move |cx| ...)`.
-* Use `Entity<T>`. This replaces `Model<T>` and `View<T>` which longer exists and should NEVER be used.

 * `Window` is now passed around explicitly. The new interface adds a `Window` reference parameter to some methods, and adds some new "*_in" methods for plumbing `Window`. The old types `WindowContext` and `ViewContext<T>` should NEVER be used.
