+We have two cloudflare workers that let us serve some assets of this repo
+from Cloudflare.
+
+* `open-source-website-assets` is used for `install.sh`
+* `docs-proxy` is used for `https://zed.dev/docs`
+
+On push to `main`, both of these (and the files they depend on) are uploaded to Cloudflare.
+
+### Deployment
+
+These functions are deployed on push to main by the deploy_cloudflare.yml workflow. Worker Rules in Cloudflare intercept requests to zed.dev and proxy them to the appropriate workers.
+
+### Testing
+
+You can use [wrangler](https://developers.cloudflare.com/workers/cli-wrangler/install-update) to test these workers locally, or to deploy custom versions.

+When the user asks you to suggest edits for a buffer, use a strict template consisting of:
+
+* A markdown code block with the file path as the language identifier.
+* The original code that should be replaced
+* A separator line (`---`)
+* The new text that should replace the original lines
+
+Each code block may only contain an edit for one single contiguous range of text. Use multiple code blocks for multiple edits.
+
+## Example
+
+If you have a buffer with the following lines:
+
+```path/to/file.rs
+fn quicksort(arr: &mut [i32]) {
+    if arr.len() <= 1 {
+        return;
+    }
+    let pivot_index = partition(arr);
+    let (left, right) = arr.split_at_mut(pivot_index);
+    quicksort(left);
+    quicksort(&mut right[1..]);
+}
+
+fn partition(arr: &mut [i32]) -> usize {
+    let last_index = arr.len() - 1;
+    let pivot = arr[last_index];
+    let mut i = 0;
+    for j in 0..last_index {
+        if arr[j] <= pivot {

+            i += 1;
+        }
+    }
+    arr.swap(i, last_index);
+    i
+}
+```
+
+And you want to replace the for loop inside `partition`, output the following.
+
+```edit path/to/file.rs
+for j in 0..last_index {
+    if arr[j] <= pivot {
+        arr.swap(i, j);
+        i += 1;
+    }

+---
+let mut j = 0;

 ## Overview
 
-Language Models can produce structured outputs that are perfect for calling functions. The most famous of these is OpenAI's tool calling. When make a chat completion you can pass a list of tools available to the model. The model will choose `0..n` tools to help them complete a user's task. It's up to _you_ to create the tools that the model can call.

+This library is designed to facilitate this interaction mode by allowing you to go from `struct` to `tool` with two simple traits, `LanguageModelTool` and `ToolView`.
 
-## Example
-
-Let's expose querying a semantic index directly by the model. First, we'll set up some _necessary_ imports
+## Using the Tool Registry
 
 ```rust
-use anyhow::Result;
-use assistant_tooling::{LanguageModelTool, ToolRegistry};
-use gpui::{App, AppContext, Task};
-use schemars::JsonSchema;
-use serde::Deserialize;
-use serde_json::json;
-```
+let mut tool_registry = ToolRegistry::new();
+tool_registry
+    .register(WeatherTool { api_client },
+    })
+    .unwrap(); // You can only register one tool per name
 
-Then we'll define the query structure the model must fill in. This _must_ derive `Deserialize` from `serde` and `JsonSchema` from the `schemars` crate.
-
-```rust
-#[derive(Deserialize, JsonSchema)]
-struct CodebaseQuery {
-    query: String,
-}
-```
-
-After that we can define our tool, with the expectation that it will need a `ProjectIndex` to search against. For this example, the index uses the same interface as `semantic_index::ProjectIndex`.
-
-```rust
-struct ProjectIndex {}
-
-impl ProjectIndex {
-    fn new() -> Self {
-        ProjectIndex {}
-    }
-
-    fn search(&self, _query: &str, _limit: usize, _cx: &AppContext) -> Task<Result<Vec<String>>> {
-        // Instead of hooking up a real index, we're going to fake it
-        if _query.contains("gpui") {
-            return Task::ready(Ok(vec![r#"// crates/gpui/src/gpui.rs
-    //! # Welcome to GPUI!
-    //!
-    //! GPUI is a hybrid immediate and retained mode, GPU accelerated, UI framework
-    //! for Rust, designed to support a wide variety of applications
-    "#
-            .to_string()]));
-        }
-        return Task::ready(Ok(vec![]));
-    }
-}
-
-struct ProjectIndexTool {
-    project_index: ProjectIndex,
-}
-```
-
-Now we can implement the `LanguageModelTool` trait for our tool by:
-
-- Defining the `Input` from the model, which is `CodebaseQuery`
-- Defining the `Output`
-- Implementing the `name` and `description` functions to provide the model information when it's choosing a tool
-- Implementing the `execute` function to run the tool
-
-```rust
-impl LanguageModelTool for ProjectIndexTool {
-    type Input = CodebaseQuery;
-    type Output = String;
-
-    fn name(&self) -> String {
-        "query_codebase".to_string()
-    }
-
-    fn description(&self) -> String {
-        "Executes a query against the codebase, returning excerpts related to the query".to_string()
-    }
-
-    fn execute(&self, query: Self::Input, cx: &AppContext) -> Task<Result<Self::Output>> {
-        let results = self.project_index.search(query.query.as_str(), 10, cx);
-
-        cx.spawn(|_cx| async move {
-            let results = results.await?;
-
-            if !results.is_empty() {
-                Ok(results.join("\n"))
-            } else {
-                Ok("No results".to_string())
-            }
-        })
-    }
-}
-```
-
-For the sake of this example, let's look at the types that OpenAI will be passing to us
-
-```rust
-// OpenAI definitions, shown here for demonstration
-#[derive(Deserialize)]
-struct FunctionCall {
-    name: String,
-    args: String,
-}
-
-#[derive(Deserialize, Eq, PartialEq)]
-enum ToolCallType {
-    #[serde(rename = "function")]
-    Function,
-    Other,
-}
-
-#[derive(Deserialize, Clone, Debug, Eq, PartialEq, Hash, Ord, PartialOrd)]
-struct ToolCallId(String);
-
-#[derive(Deserialize)]
-#[serde(tag = "type", rename_all = "snake_case")]
-enum ToolCall {
-    Function {
-        #[allow(dead_code)]
-        id: ToolCallId,
-        function: FunctionCall,
-    },
-    Other {
-        #[allow(dead_code)]
-        id: ToolCallId,
-    },
-}
-
-#[derive(Deserialize)]
-struct AssistantMessage {
-    role: String,
-    content: Option<String>,
-    tool_calls: Option<Vec<ToolCall>>,
-}
-```
-
-When the model wants to call tools, it will pass a list of `ToolCall`s. When those are `function`s that we can handle, we'll pass them to our `ToolRegistry` to get a future that we can await.
-
-```rust
-// Inside `fn main()`
-App::new().run(|cx: &mut AppContext| {
-    let tool = ProjectIndexTool {
-        project_index: ProjectIndex::new(),
-    };
-
-    let mut registry = ToolRegistry::new();
-    let registered = registry.register(tool);
-    assert!(registered.is_ok());
-```
-
-Let's pretend the model sent us back a message requesting
-
-```rust
-let model_response = json!({
-    "role": "assistant",
-    "tool_calls": [
-        {

-We can now use our registry to call the tool.
+Once the stream of tokens is complete, you can exexute the tool call by calling `tool_registry.execute_tool_call(tool_call, cx)`, which returns a `Task<Result<()>>`.
 
-```rust
-let task = registry.call(
-    tool_call.name,
-    tool_call.args,
-);
-
-cx.spawn(|_cx| async move {
-    let result = task.await?;
-    println!("{}", result.unwrap());
-    Ok(())
-})
-```
+As the tokens stream in and tool calls are executed, your `ToolView` will get updates. Render each tool call by passing that `tool_call` in to `tool_registry.render_tool_call(tool_call, cx)`. The final message for the model can be pulled by calling `self.tool_registry.content_for_tool_call( tool_call, &mut project_context, cx, )`.
