zed 0.161.2

/cherry-pick v0.161.x

-# Code Change Workflow
-
-Your task is to guide the user through code changes using a series of steps. Each step should describe a high-level change, which can consist of multiple edits to distinct locations in the codebase.
-
-## Output Example
-
-Provide output as XML, with the following format:
-
-<step>
-Update the Person struct to store an age
-
-```rust
-struct Person {
-    // existing fields...
-    age: u8,
-    height: f32,
-    // existing fields...
-}
-
-impl Person {
-    fn age(&self) -> u8 {
-        self.age
-    }
-}
-```
-
-<edit>
-<path>src/person.rs</path>
-<operation>insert_before</operation>
-<search>height: f32,</search>
-<description>Add the age field</description>
-</edit>
-
-<edit>
-<path>src/person.rs</path>
-<operation>insert_after</operation>
-<search>impl Person {</search>
-<description>Add the age getter</description>
-</edit>
-</step>
-
-## Output Format
-
-First, each `<step>` must contain a written description of the change that should be made. The description should begin with a high-level overview, and can contain markdown code blocks as well. The description should be self-contained and actionable.
-
-After the description, each `<step>` must contain one or more `<edit>` tags, each of which refer to a specific range in a source file. Each `<edit>` tag must contain the following child tags:
-
-### `<path>` (required)
-
-This tag contains the path to the file that will be changed. It can be an existing path, or a path that should be created.
-
-### `<search>` (optional)
-
-This tag contains a search string to locate in the source file, e.g. `pub fn baz() {`. If not provided, the new content will be inserted at the top of the file. Make sure to produce a string that exists in the source file and that isn't ambiguous. When there's ambiguity, add more lines to the search to eliminate it.
-
-### `<description>` (required)
-
-This tag contains a single-line description of the edit that should be made at the given location.
-
-### `<operation>` (required)
-
-This tag indicates what type of change should be made, relative to the given location. It can be one of the following:
-- `update`: Rewrites the specified string entirely based on the given description.
-- `create`: Creates a new file with the given path based on the provided description.
-- `insert_before`: Inserts new text based on the given description before the specified search string.
-- `insert_after`: Inserts new text based on the given description after the specified search string.
-- `delete`: Deletes the specified string from the containing file.
-
-<guidelines>
-- There's no need to describe *what* to do, just *where* to do it.
-- Only reference locations that actually exist (unless you're creating a file).
-- If creating a file, assume any subsequent updates are included at the time of creation.
-- Don't create and then update a file. Always create new files in one hot.
-- Prefer multiple edits to smaller regions, as opposed to one big edit to a larger region.
-- Don't produce edits that intersect each other. In that case, merge them into a bigger edit.
-- Never nest an edit with another edit. Never include CDATA. All edits are leaf nodes.
-- Descriptions are required for all edits except delete.
-- When generating multiple edits, ensure the descriptions are specific to each individual operation.
-- Avoid referring to the search string in the description. Focus on the change to be made, not the location where it's made. That's implicit with the `search` string you provide.
-- Don't generate multiple edits at the same location. Instead, combine them together in a single edit with a succinct combined description.
-- Always ensure imports are added if you're referencing symbols that are not in scope.

-<overview>
-Your task is to map a step from a workflow to locations in source code where code needs to be changed to fulfill that step.
-Given a workflow containing background context plus a series of <step> tags, you will resolve *one* of these step tags to resolve to one or more locations in the code.
-With each location, you will produce a brief, one-line description of the changes to be made.
-
-<guidelines>
-- There's no need to describe *what* to do, just *where* to do it.
-- Only reference locations that actually exist (unless you're creating a file).
-- If creating a file, assume any subsequent updates are included at the time of creation.
-- Don't create and then update a file. Always create new files in shot.
-- Prefer updating symbols lower in the syntax tree if possible.
-- Never include suggestions on a parent symbol and one of its children in the same suggestions block.
-- Never nest an operation with another operation or include CDATA or other content. All suggestions are leaf nodes.
-- Descriptions are required for all suggestions except delete.
-- When generating multiple suggestions, ensure the descriptions are specific to each individual operation.
-- Avoid referring to the location in the description. Focus on the change to be made, not the location where it's made. That's implicit with the symbol you provide.
-- Don't generate multiple suggestions at the same location. Instead, combine them together in a single operation with a succinct combined description.
-- To add imports respond with a suggestion where the `"symbol"` key is set to `"#imports"`

+The user of a code editor wants to make a change to their codebase.
+You must describe the change using the following XML structure:
+
+- <patch> - A group of related code changes.
+  Child tags:
+    - <title> (required) - A high-level description of the changes. This should be as short
+      as possible, possibly using common abbreviations.
+    - <edit> (1 or more) - An edit to make at a particular range within a file.
+      Includes the following child tags:
+        - <path> (required) - The path to the file that will be changed.
+        - <description> (optional) - An arbitrarily-long comment that describes the purpose
+          of this edit.
+        - <old_text> (optional) - An excerpt from the file's current contents that uniquely
+          identifies a range within the file where the edit should occur. If this tag is not
+          specified, then the entire file will be used as the range.
+        - <new_text> (required) - The new text to insert into the file.
+        - <operation> (required) - The type of change that should occur at the given range
+          of the file. Must be one of the following values:
+            - `update`: Replaces the entire range with the new text.
+            - `insert_before`: Inserts the new text before the range.
+            - `insert_after`: Inserts new text after the range.
+            - `create`: Creates a new file with the given path and the new text.
+            - `delete`: Deletes the specified range from the file.
+
+<guidelines>
+- Never provide multiple edits whose ranges intersect each other. Instead, merge them into one edit.
+- Prefer multiple edits to smaller, disjoint ranges, rather than one edit to a larger range.
+- There's no need to escape angle brackets within XML tags.
