-# Cline Protobuf Development Guide
-
-This guide outlines how to add new gRPC endpoints for communication between the webview (frontend) and the extension host (backend).
-
-## Overview
-
-Cline uses [Protobuf](https://protobuf.dev/) to define a strongly-typed API, ensuring efficient and type-safe communication. All definitions are in the `/proto` directory. The compiler and plugins are included as project dependencies, so no manual installation is needed.
-
-## Key Concepts & Best Practices
-
--   **File Structure**: Each feature domain should have its own `.proto` file (e.g., `account.proto`, `task.proto`).
--   **Message Design**:
-    -   For simple, single-value data, use the shared types in `proto/common.proto` (e.g., `StringRequest`, `Empty`, `Int64Request`). This promotes consistency.
-    -   For complex data structures, define custom messages within the feature's `.proto` file (see `task.proto` for examples like `NewTaskRequest`).
--   **Naming Conventions**:
-    -   Services: `PascalCaseService` (e.g., `AccountService`).
-    -   RPCs: `camelCase` (e.g., `accountEmailIdentified`).
-    -   Messages: `PascalCase` (e.g., `StringRequest`).
--   **Streaming**: For server-to-client streaming, use the `stream` keyword on the response type. See `subscribeToAuthCallback` in `account.proto` for an example.
-
----
-
-## 4-Step Development Workflow
-
-Here’s how to add a new RPC, using `scrollToSettings` as an example.
-
-### 1. Define the RPC in a `.proto` File
-
-Add your service method to the appropriate file in the `proto/` directory.
-
-**File: `proto/ui.proto`**
-```proto
-service UiService {
-  // ... other RPCs
-  // Scrolls to a specific settings section in the settings view
-  rpc scrollToSettings(StringRequest) returns (KeyValuePair);
-}
-```
-Here, we use the common `StringRequest` and `KeyValuePair` types.
-
-### 2. Compile Definitions
-
-After editing a `.proto` file, regenerate the TypeScript code. From the project root, run:
-```bash
-npm run protos
-```
-This command compiles all `.proto` files and outputs the generated code to `src/generated/` and `src/shared/`. Do not edit these generated files manually.
-
-### 3. Implement the Backend Handler
-
-Create the RPC implementation in the backend. Handlers are located in `src/core/controller/[service-name]/`.
-
-**File: `src/core/controller/ui/scrollToSettings.ts`**
-```typescript
-import { Controller } from ".."
-import { StringRequest, KeyValuePair } from "../../../shared/proto/common"
-
-/**
- * Executes a scroll to settings action
- * @param controller The controller instance
- * @param request The request containing the ID of the settings section to scroll to
- * @returns KeyValuePair with action and value fields for the UI to process
- */
-export async function scrollToSettings(controller: Controller, request: StringRequest): Promise<KeyValuePair> {
-	return KeyValuePair.create({
-		key: "scrollToSettings",
-		value: request.value || "",
-	})
-}
-```
-
-### 4. Call the RPC from the Webview
-
-Call the new RPC from a React component in `webview-ui/`. The generated client makes this simple.
-
-**File: `webview-ui/src/components/browser/BrowserSettingsMenu.tsx`** (Example)
-```tsx
-import { UiServiceClient } from "../../../services/grpc"
-import { StringRequest } from "../../../../shared/proto/common"
-
-// ... inside a React component
-const handleMenuClick = async () => {
-    try {
-        await UiServiceClient.scrollToSettings(StringRequest.create({ value: "browser" }))
-    } catch (error) {
-        console.error("Error scrolling to browser settings:", error)
-    }
-}
-```

 Thanks to [Claude 3.7 Sonnet's agentic coding capabilities](https://www.anthropic.com/claude/sonnet), Cline can handle complex software development tasks step-by-step. With tools that let him create & edit files, explore large projects, use the browser, and execute terminal commands (after you grant permission), he can assist you in ways that go beyond code completion or tech support. Cline can even use the Model Context Protocol (MCP) to create new tools and extend his own capabilities. While autonomous AI scripts traditionally run in sandboxed environments, this extension provides a human-in-the-loop GUI to approve every file change and terminal command, providing a safe and accessible way to explore the potential of agentic AI.

-	/>
-</Frame>
-
-## Setup
-
-First, you'll need to install and authenticate Claude Code on your system:
-
-1. **Install Claude Code**: Follow Anthropic's [official setup guide](https://docs.anthropic.com/en/docs/claude-code/setup) to install and authenticate the Claude CLI.
-
-2. **Configure in Cline**:
-    - Open Cline settings (⚙️ icon)
-    - Select **Claude Code** from the **API Provider** dropdown
-    - Set the path to your Claude CLI executable (usually just `claude` if it's in your PATH)
-

-	<img
-		src="https://storage.googleapis.com/cline_public_images/docs/assets/claude-code-setup.gif"
-		alt="Setting up the Claude Code provider in Cline"
-	/>
-</Frame>
-
-### Finding your Claude Code path
-
-If you're not sure where Claude Code is installed:
-
--   **macOS / Linux**: Run `which claude` in your terminal
--   **Windows (Command Prompt)**: Run `where claude`
--   **Windows (PowerShell)**: Run `Get-Command claude`
-
-## Supported Models
-
-The Claude Code provider supports these models:
-
--   `claude-sonnet-4-20250514` (Recommended)
--   `claude-opus-4-20250514`
--   `claude-3-7-sonnet-20250219`
--   `claude-3-5-sonnet-20241022`
--   `claude-3-5-haiku-20241022`
-
-## How it works
-
-When you use Claude Code with Cline, here's what happens behind the scenes:
-
-Cline wraps the Claude Code CLI to handle your requests. Each time you send a message, Cline starts a new `claude` process, sends your conversation, and streams the response back. The AI reasoning comes from Claude Code, but all the actual file editing, terminal commands, and other tools are handled by Cline.
-
-The main difference you'll notice is that responses don't stream character-by-character like other providers. Instead, Claude Code processes your full request before sending back the complete response.
-
-## Limitations
-
-There are a few things to keep in mind with Claude Code:
-
--   Images in your messages get converted to text placeholders since Claude Code doesn't support image uploads through the CLI
--   Prompt caching isn't available with this provider
--   Responses don't stream in real-time like other providers
-
-## Troubleshooting
-
-If you run into issues:
-
-**Authentication problems**: Make sure you're logged into Claude Code with your subscription account. Run `claude auth status` to check.
-
-**Path issues**: Double-check that the Claude CLI path in Cline's settings is correct. Try running `claude --version` in your terminal to verify it's working.
-
-**Still having trouble?** We're actively improving this integration. Report issues on our [GitHub](https://github.com/cline/cline/issues) or ask for help in our [Discord](https://discord.gg/cline).
-
-## Usage with subscriptions
-
-If you have a Claude Max subscription, your usage in Cline shows up as $0.00 in the billing interface since you're not paying additional API costs. Your usage still counts against your subscription limits, but you won't see per-token charges.

 This way, if we're comparing two models and one gets a 10% success rate on its valid diff edit attempts, and another gets 90%, we have a much clearer picture of their actual diff-generating capabilities. It avoids muddying the waters with attempts where the model didn't even try to perform the specific action we're evaluating. This approach helps us isolate and measure the diff-editing skill more directly, despite the non-deterministic nature of these models.
 
-## Replays
+## Some known edge cases
 
-You can also use the replay argument to replay a previous benchmark run. This is super useful for iterating on our diffing algorithms without having to re-run expensive and time-consuming LLM calls.
+I noticed that some of the current conversation jsons in the `./cases` folder are a little big bogus. Here's a running list of these areas:
 
-When you run an evaluation, every detail is stored in the database—including the raw, unmodified output from the model. The replay feature takes advantage of this by pulling that raw output and feeding it into a *different* diffing algorithm. This lets you isolate the performance of the diffing logic itself. We can see if a new algorithm is better at applying the exact same set of diffs that a model generated in a previous run.
-
-This process is blazingly fast and free, as it completely bypasses the need to make new API calls. It ensures a true apples-to-apples comparison between diffing strategies, since the model's output—the "ground truth" for the evaluation—remains identical.
-
-Here’s an example of how you would replay a previous run with a new diffing algorithm:
-
-```shell
-cd evals && npm run diff-eval -- --replay-run-id 9902189e-63a8-4210-a4fc-fe59e2eaf2c2 --diff-apply-file diff-06-23-25 --verbose
-```
-
-In this command:
--   `--replay-run-id` specifies the original run we want to use as our ground truth.
--   `--diff-apply-file` tells the script to use the new diffing logic from the `diff-06-23-25.ts` file.
-
-The script will then create a new run in the database that mirrors the original, but with the results of applying the new diffing algorithm. This allows for a direct comparison in the dashboard, helping us quickly see which of our diffing strategies is the most robust.
+- ~~What if the conversation json was using a model with a massive context window, like Google Gemini's 1M context window, and we're now re-rolling that case on a smaller context window model like claude 4 (200k) or grok-3 (128k)? It's def gonna fail, and we shouldn't just keep trying. We should have a smart system for selecting which cases we can use given the arguments passed in. For example, if we pass in claude and grok with `max cases = 2`, we shouldn't just pick the first two jsons in the folder. We should go through, use a tokenizer, and make sure it would fit with some padding like 20k tokens. Use tiktoken. 20k padding will be sufficient even though different models tokenize differently.~~
+- There are some weird jsons, where something weird happen, where essentially there's a fluke. Maybe the user was using an extremely dumb model that just hallucinated a fake filepath. Now when we try to reroll that case, we never get a valid case. This can easily be handled by making sure that the file is present before selecting that eval for testing. By "file is present" I mean, that file_contents is present in the eval. Additionally, we should in the streamlit dashboard show cases where getting a valid attempt is a challenge, so we can review those cases more easily and throw them out if they're bogus. Maybe a special tab/page in the dashboard for this purpose. Across all runs / cases, what the most consistently problematic cases are. Pop one open to see the case formatted json with all the user/assistant turns.

- *    - If it does, jumps ahead by the search block size
- *    - Checks if that line matches the end anchor
- *    - All comparisons are done after trimming whitespace
- *
- * This approach is particularly useful for matching blocks of code where:
- * - The exact content might have minor differences
- * - The beginning and end of the block are distinctive enough to serve as anchors
- * - The overall structure (number of lines) remains the same
- *
- * @param originalContent - The full content of the original file
- * @param searchContent - The content we're trying to find in the original file
- * @param startIndex - The character index in originalContent where to start searching
- * @returns A tuple of [startIndex, endIndex] if a match is found, false otherwise

-/**
- * This function reconstructs the file content by applying a streamed diff (in a
- * specialized SEARCH/REPLACE block format) to the original file content. It is designed
- * to handle both incremental updates and the final resulting file after all chunks have
- * been processed.
- *
- * The diff format is a custom structure that uses three markers to define changes:
- *
- *   ------- SEARCH
- *   [Exact content to find in the original file]
- *   =======
- *   [Content to replace with]
- *   +++++++ REPLACE
- *
- * Behavior and Assumptions:
- * 1. The file is processed chunk-by-chunk. Each chunk of `diffContent` may contain
- *    partial or complete SEARCH/REPLACE blocks. By calling this function with each
- *    incremental chunk (with `isFinal` indicating the last chunk), the final reconstructed
- *    file content is produced.
- *
- * 2. Matching Strategy (in order of attempt):
- *    a. Exact Match: First attempts to find the exact SEARCH block text in the original file
- *    b. Line-Trimmed Match: Falls back to line-by-line comparison ignoring leading/trailing whitespace
- *    c. Block Anchor Match: For blocks of 3+ lines, tries to match using first/last lines as anchors
- *    If all matching strategies fail, an error is thrown.
- *
- * 3. Empty SEARCH Section:
- *    - If SEARCH is empty and the original file is empty, this indicates creating a new file
- *      (pure insertion).
- *    - If SEARCH is empty and the original file is not empty, this indicates a complete
- *      file replacement (the entire original content is considered matched and replaced).
- *
- * 4. Applying Changes:
- *    - Before encountering the "=======" marker, lines are accumulated as search content.
- *    - After "=======" and before ">>>>>>> REPLACE", lines are accumulated as replacement content.
- *    - Once the block is complete (">>>>>>> REPLACE"), the matched section in the original
- *      file is replaced with the accumulated replacement lines, and the position in the original
- *      file is advanced.
- *
- * 5. Incremental Output:
- *    - As soon as the match location is found and we are in the REPLACE section, each new
- *      replacement line is appended to the result so that partial updates can be viewed
- *      incrementally.
- *
- * 6. Partial Markers:
- *    - If the final line of the chunk looks like it might be part of a marker but is not one
- *      of the known markers, it is removed. This prevents incomplete or partial markers
- *      from corrupting the output.
- *
- * 7. Finalization:
- *    - Once all chunks have been processed (when `isFinal` is true), any remaining original
- *      content after the last replaced section is appended to the result.
- *    - Trailing newlines are not forcibly added. The code tries to output exactly what is specified.
- *
- * Errors:
- * - If the search block cannot be matched using any of the available matching strategies,
- *   an error is thrown.

-/**
- * Attempts to match blocks of code by using the first and last lines as anchors.
- * This is a third-tier fallback strategy that helps match blocks where we can identify
- * the correct location by matching the beginning and end, even if the exact content
- * differs slightly.
- *
- * The matching strategy:
- * 1. Only attempts to match blocks of 3 or more lines to avoid false positives
- * 2. Extracts from the search content:
- *    - First line as the "start anchor"
- *    - Last line as the "end anchor"
- * 3. For each position in the original content:
- *    - Checks if the next line matches the start anchor
- *    - If it does, jumps ahead by the search block size
- *    - Checks if that line matches the end anchor
- *    - All comparisons are done after trimming whitespace
- *
- * This approach is particularly useful for matching blocks of code where:
- * - The exact content might have minor differences
- * - The beginning and end of the block are distinctive enough to serve as anchors
- * - The overall structure (number of lines) remains the same
- *
- * @param originalContent - The full content of the original file
- * @param searchContent - The content we're trying to find in the original file
- * @param startIndex - The character index in originalContent where to start searching
- * @returns A tuple of [startIndex, endIndex] if a match is found, false otherwise

-/**
- * This function reconstructs the file content by applying a streamed diff (in a
- * specialized SEARCH/REPLACE block format) to the original file content. It is designed
- * to handle both incremental updates and the final resulting file after all chunks have
- * been processed.
- *
- * The diff format is a custom structure that uses three markers to define changes:
- *
- *   ------- SEARCH
- *   [Exact content to find in the original file]
- *   =======
- *   [Content to replace with]
- *   +++++++ REPLACE
- *
- * Behavior and Assumptions:
- * 1. The file is processed chunk-by-chunk. Each chunk of `diffContent` may contain
- *    partial or complete SEARCH/REPLACE blocks. By calling this function with each
- *    incremental chunk (with `isFinal` indicating the last chunk), the final reconstructed
- *    file content is produced.
- *
- * 2. Matching Strategy (in order of attempt):
- *    a. Exact Match: First attempts to find the exact SEARCH block text in the original file
- *    b. Line-Trimmed Match: Falls back to line-by-line comparison ignoring leading/trailing whitespace
- *    c. Block Anchor Match: For blocks of 3+ lines, tries to match using first/last lines as anchors
- *    If all matching strategies fail, an error is thrown.
- *
- * 3. Empty SEARCH Section:
- *    - If SEARCH is empty and the original file is empty, this indicates creating a new file
- *      (pure insertion).
- *    - If SEARCH is empty and the original file is not empty, this indicates a complete
- *      file replacement (the entire original content is considered matched and replaced).
- *
- * 4. Applying Changes:
- *    - Before encountering the "=======" marker, lines are accumulated as search content.
- *    - After "=======" and before ">>>>>>> REPLACE", lines are accumulated as replacement content.
- *    - Once the block is complete (">>>>>>> REPLACE"), the matched section in the original
- *      file is replaced with the accumulated replacement lines, and the position in the original
- *      file is advanced.
- *
- * 5. Incremental Output:
- *    - As soon as the match location is found and we are in the REPLACE section, each new
- *      replacement line is appended to the result so that partial updates can be viewed
- *      incrementally.
- *
- * 6. Partial Markers:
- *    - If the final line of the chunk looks like it might be part of a marker but is not one
- *      of the known markers, it is removed. This prevents incomplete or partial markers
- *      from corrupting the output.
- *
- * 7. Finalization:
- *    - Once all chunks have been processed (when `isFinal` is true), any remaining original
- *      content after the last replaced section is appended to the result.
- *    - Trailing newlines are not forcibly added. The code tries to output exactly what is specified.
- *
- * Errors:
- * - If the search block cannot be matched using any of the available matching strategies,
- *   an error is thrown.

+Description: Respond to the user's inquiry in an effort to plan a solution to the user's task. This tool should be used when you need to provide a response to a question or statement from the user about how you plan to accomplish the task. This tool is only available in PLAN MODE. The environment_details will specify the current mode, if it is not PLAN MODE then you should not use this tool. Depending on the user's message, you may ask questions to get clarification about the user's request, architect a solution to the task, and to brainstorm ideas with the user. For example, if the user's task is to create a website, you may start by asking some clarifying questions, then present a detailed plan for how you will accomplish the task given the context, and perhaps engage in a back and forth to finalize the details before the user switches you to ACT MODE to implement the solution. IMPORTANT NOTE: You should NOT ask for permission to read files or explore the repo. Just do that proactively. This tool should only be used when you've already gathered enough information to make a plan, or if you have a question for the user.
 Parameters:
 - response: (required) The response to provide to the user. Do not try to use tools in this parameter, this is simply a chat response. (You MUST use the response parameter, do not simply place the response text directly within <plan_mode_respond> tags.)

 ## What is PLAN MODE?
 
 - While you are usually in ACT MODE, the user may switch to PLAN MODE in order to have a back and forth with you to plan how to best accomplish the task. 
-- When starting in PLAN MODE, depending on the user's request, you may need to do some information gathering e.g. using read_file or search_files to get more context about the task. You may also ask the user clarifying questions with ask_followup_question to get a better understanding of the task. You may return mermaid diagrams to visually display your understanding.
-- Once you've gained more context about the user's request, you should architect a detailed plan for how you will accomplish the task. Returning mermaid diagrams may be helpful here as well. Present the plan to the user using the plan_mode_respond tool.

+- Once you've gained more context about the user's request, you should architect a detailed plan for how you will accomplish the task. Returning mermaid diagrams may be helpful here as well.
 - Then you might ask the user if they are pleased with this plan, or if they would like to make any changes. Think of this as a brainstorming session where you can discuss the task and plan the best way to accomplish it.
 - If at any point a mermaid diagram would make your plan clearer to help the user quickly see the structure, you are encouraged to include a Mermaid code block in the response. (Note: if you use colors in your mermaid diagrams, be sure to use high contrast colors so the text is readable.)
 - Finally once it seems like you've reached a good plan, ask the user to switch you back to ACT MODE to implement the solution.

 - When you want to modify a file, use the replace_in_file or write_to_file tool directly with the desired changes. You do not need to display the changes before using the tool.
 - Do not ask for more information than necessary. Use the tools provided to accomplish the user's request efficiently and effectively. When you've completed your task, you must use the attempt_completion tool to present the result to the user. The user may provide feedback, which you can use to make improvements and try again.
 - You are only allowed to ask the user questions using the ask_followup_question tool. Use this tool only when you need additional details to complete a task, and be sure to use a clear and concise question that will help you move forward with the task. However if you can use the available tools to avoid having to ask the user questions, you should do so. For example, if the user mentions a file that may be in an outside directory like the Desktop, you should use the list_files tool to list the files in the Desktop and check if the file they are talking about is there, rather than asking the user to provide the file path themselves.
-- When the user is being vague, you should be proactive about asking clarifying questions using the ask_followup_question tool to ensure you understand their request. However, if you can infer the user's intent based on the context and available tools, you should proceed without asking unnecessary questions
 - When executing commands, if you don't see the expected output, assume the terminal executed the command successfully and proceed with the task. The user's terminal may be unable to stream the output back properly. If you absolutely need to see the actual terminal output, use the ask_followup_question tool to request the user to copy and paste it back to you.
 - The user may provide a file's contents directly in their message, in which case you shouldn't use the read_file tool to get the file contents again since you already have it.
 - Your goal is to try to accomplish the user's task, NOT engage in a back and forth conversation.${
