 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.
+* Use `Entity<T>`. This replaces `Model<T>` and `View<T>` which no longer exist and should NEVER be used.

 * Use `Context<T>` references. This replaces `ModelContext<T>` which no 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.

+- Use `<old_text>` and `<new_text>` tags to replace content
+- `<old_text>` must exactly match existing file content, including indentation
+- `<old_text>` must come from the actual file, not an outline
+- `<old_text>` cannot be empty
+- Be minimal with replacements:
+  - For unique lines, include only those lines
+  - For non-unique lines, include enough context to identify them
+- Do not escape quotes, newlines, or other characters within tags
+- For multiple occurrences, repeat the same tag pair for each instance
+- Edits are sequential - each assumes previous edits are already applied
+- Only edit the specified file
+- Always close all tags properly

-- `old_text` MUST exactly match the existing file content, character for character, including indentation.
-- `old_text` MUST NEVER come from the outline, but from actual lines in the file.
-- Strive to be minimal in the lines you replace in `old_text`:
-  - If the lines you want to replace are unique, you MUST include just those in the `old_text`.
-  - If the lines you want to replace are NOT unique, you MUST include enough context around them in `old_text` to distinguish them from other lines.
-- If you want to replace many occurrences of the same text, repeat the same `old_text`/`new_text` pair multiple times and I will apply them sequentially, one occurrence at a time.
-- When reporting multiple edits, each edit assumes the previous one has already been applied! Therefore, you must ensure `old_text` doesn't reference text that has already been modified by a previous edit.
-- Don't explain the edits, just report them.
-- Only edit the file specified in `<file_to_edit>` and NEVER include edits to other files!
