-## Licensing
-
-License information for third party dependencies must be correctly provided for CI to pass.
-
-We use [`cargo-about`](https://github.com/EmbarkStudios/cargo-about) to automatically comply with open source licenses. If CI is failing, check the following:
-
- Is it showing a `no license specified` error for a crate you've created? If so, add `publish = false` under `[package]` in your crate's Cargo.toml.
- Is the error `failed to satisfy license requirements` for a dependency? If so, first determine what license the project has and whether this system is sufficient to comply with this license's requirements. If you're unsure, ask a lawyer. Once you've verified that this system is acceptable add the license's SPDX identifier to the `accepted` array in `script/licenses/zed-licenses.toml`.
- Is `cargo-about` unable to find the license for a dependency? If so, add a clarification field at the end of `script/licenses/zed-licenses.toml`, as specified in the [cargo-about book](https://embarkstudios.github.io/cargo-about/cli/generate/config.html#crate-configuration).

+# Assistant Tooling
+
+Bringing OpenAI compatible tool calling to GPUI.
+
+This unlocks:
+
+- **Structured Extraction** of model responses
+- **Validation** of model inputs
+- **Execution** of chosen toolsn
+
+## 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.
+
+> **User**: "Hey I need help with implementing a collapsible panel in GPUI"
+>
+> **Assistant**: "Sure, I can help with that. Let me see what I can find."
+>
+> `tool_calls: ["name": "query_codebase", arguments: "{ 'query': 'GPUI collapsible panel' }"]`
+>
+> `result: "['crates/gpui/src/panel.rs:12: impl Panel { ... }', 'crates/gpui/src/panel.rs:20: impl Panel { ... }']"`
+>
+> **Assistant**: "Here are some excerpts from the GPUI codebase that might help you."
+
+This library is designed to facilitate this interaction mode by allowing you to go from `struct` to `tool` with a simple trait, `LanguageModelTool`.
+
+## Example
+
+Let's expose querying a semantic index directly by the model. First, we'll set up some _necessary_ imports
+
+```rust
+use anyhow::Result;
+use assistant_tooling::{LanguageModelTool, ToolRegistry};
+use gpui::{App, AppContext, Task};
+use schemars::JsonSchema;
+use serde::Deserialize;
+use serde_json::json;
+```
+
+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": [
+        {
+            "id": "call_1",
+            "function": {
+                "name": "query_codebase",
+                "args": r#"{"query":"GPUI Task background_executor"}"#
+            },
+            "type": "function"
+        }
+    ]
+});
+
+let message: AssistantMessage = serde_json::from_value(model_response).unwrap();
+
+// We know there's a tool call, so let's skip straight to it for this example
+let tool_calls = message.tool_calls.as_ref().unwrap();
+let tool_call = tool_calls.get(0).unwrap();
+```
+
+We can now use our registry to call the tool.
+
+```rust
+let task = registry.call(
+    tool_call.name,
+    tool_call.args,
+);
+
+cx.spawn(|_cx| async move {
+    let result = task.await?;
+    println!("{}", result.unwrap());
+    Ok(())
+})
+```

 # Local Development

-Detailed instructions on getting started are [here](https://zed.dev/docs/local-collaboration).
+## Database setup
+
+Before you can run the collab server locally, you'll need to set up a zed Postgres database.
+
+```
+script/bootstrap
+```
+
+This script will set up the `zed` Postgres database, and populate it with some users. It requires internet access, because it fetches some users from the GitHub API.
+
+The script will create several _admin_ users, who you'll sign in as by default when developing locally. The GitHub logins for the default users are specified in the `seed.default.json` file.
+
+To use a different set of admin users, create `crates/collab/seed.json`.
+
+```json
+{
+  "admins": ["yourgithubhere"],
+  "channels": ["zed"],
+  "number_of_users": 20
+}
+```
+
+## Testing collaborative features locally
+
+In one terminal, run Zed's collaboration server and the livekit dev server:
+
+```
+foreman start
+```
+
+In a second terminal, run two or more instances of Zed.
+
+```
+script/zed-local -2
+```
+
+This script starts one to four instances of Zed, depending on the `-2`, `-3` or `-4` flags. Each instance will be connected to the local `collab` server, signed in as a different user from `seed.json` or `seed.default.json`.
