+# 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)
+    }
+}
+```

+description: "Use your Claude Max subscription with Cline instead of paying per token. Learn how to set up and configure the Claude Code provider."
+---
+
+**Website:** [https://docs.anthropic.com/en/docs/claude-code/setup](https://docs.anthropic.com/en/docs/claude-code/setup)
+
+The Claude Code provider lets you use your existing Claude subscription with Cline. If you have Claude Max, this means you can use Claude in Cline without paying extra API costs.

+		alt="Using the Claude Code provider in Cline with Opus model"
+	/>
+</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)
+
+<Frame>
+	<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.
+
+For more details about using Claude Code with your subscription, check out Anthropic's documentation:

+## Diff Edit Evaluations
+
+The Cline Evaluation System includes a specialized suite for evaluating how well models can make precise edits to files using the `replace_in_file` tool.
+
+### Overview
+
+Diff edit evaluations test a model's ability to:
+
+1. Understand file content and identify specific sections to modify
+2. Generate correct SEARCH/REPLACE blocks for targeted edits
+3. Successfully apply changes without introducing errors
+
+### Directory Structure
+
+```
+diff-edits/
+├── cases/                  # Test case JSON files
+├── results/                # Evaluation results
+├── ClineWrapper.ts         # Wrapper for model interaction
+├── TestRunner.ts           # Main test execution logic
+├── types.ts                # Type definitions
+├── diff-apply/             # Diff application logic
+├── parsing/                # Assistant message parsing
+└── prompts/                # System prompts
+```
+
+### Creating Test Cases
+
+Test cases are defined as JSON files in the `diff-edits/cases/` directory. Each test case should include:
+
+```json
+{
+  "test_id": "example_test_1",
+  "messages": [
+    {
+      "role": "user",
+      "text": "Please fix the bug in this code...",
+      "images": []
+    },
+    {
+      "role": "assistant",
+      "text": "I'll help you fix that bug..."
+    }
+  ],
+  "file_contents": "// Original file content here\nfunction example() {\n  // Code with bug\n}",
+  "file_path": "src/example.js",
+  "system_prompt_details": {
+    "mcp_string": "",
+    "cwd_value": "/path/to/working/directory",
+    "browser_use": false,
+    "width": 900,
+    "height": 600,
+    "os_value": "macOS",
+    "shell_value": "/bin/zsh",
+    "home_value": "/Users/username",
+    "user_custom_instructions": ""
+  },
+  "original_diff_edit_tool_call_message": ""
+}
+```
+
+### Running Diff Edit Evaluations
+
+#### Single Model Evaluation
+
+```bash
+cd evals/cli
+node dist/index.js run-diff-eval --model-ids "anthropic/claude-3-5-sonnet-20241022"
+```
+
+#### Multi-Model Evaluation
+
+Compare multiple models in a single evaluation run:
+
+```bash
+# Compare Claude and Grok models
+node dist/index.js run-diff-eval \
+  --model-ids "anthropic/claude-3-5-sonnet-20241022,x-ai/grok-beta" \
+  --max-cases 10 \
+  --valid-attempts-per-case 3 \
+  --verbose
+
+# Compare multiple Claude variants
+node dist/index.js run-diff-eval \
+  --model-ids "anthropic/claude-3-5-sonnet-20241022,anthropic/claude-3-5-haiku-20241022,anthropic/claude-3-opus-20240229" \
+  --max-cases 5 \
+  --valid-attempts-per-case 2 \
+  --parallel
+```
+
+#### Options
+
+- `--model-ids`: Comma-separated list of model IDs to evaluate (required)
+- `--system-prompt-name`: System prompt to use (default: "basicSystemPrompt")
+- `--valid-attempts-per-case`: Number of attempts per test case per model (default: 1)
+- `--max-cases`: Maximum number of test cases to run (default: all available)
+- `--parsing-function`: Function to parse assistant messages (default: "parseAssistantMessageV2")
+- `--diff-edit-function`: Function to apply diffs (default: "constructNewFileContentV2")
+- `--test-path`: Path to test cases (default: diff-edits/cases)
+- `--thinking-budget`: Tokens allocated for thinking (default: 0)
+- `--parallel`: Run tests in parallel (flag)
+- `--replay`: Use pre-recorded LLM output (flag)
+- `--verbose`: Enable detailed logging (flag)
+
+#### Examples
+
+```bash
+# Quick test with 2 models, 4 cases, 2 attempts each
+node dist/index.js run-diff-eval \
+  --model-ids "anthropic/claude-3-5-sonnet-20241022,x-ai/grok-beta" \
+  --max-cases 4 \
+  --valid-attempts-per-case 2 \
+  --verbose
+
+# Comprehensive evaluation with parallel execution
+node dist/index.js run-diff-eval \
+  --model-ids "anthropic/claude-3-5-sonnet-20241022,anthropic/claude-3-5-haiku-20241022" \
+  --system-prompt-name claude4SystemPrompt \
+  --valid-attempts-per-case 5 \
+  --max-cases 20 \
+  --parallel \
+  --verbose
+```
+
+### Database Storage & Analytics
+
+All evaluation results are automatically stored in a SQLite database (`diff-edits/evals.db`) for advanced analytics and comparison. The database includes:
+
+- **System Prompts**: Versioned system prompt content with hashing for deduplication
+- **Processing Functions**: Versioned parsing and diff-edit function configurations
+- **Files**: Original and edited file content with content-based hashing
+- **Runs**: Evaluation run metadata and configuration
+- **Cases**: Individual test case information with context tokens
+- **Results**: Detailed results with timing, cost, and success metrics
+
+### Interactive Dashboard
+
+Launch the Streamlit dashboard to visualize and analyze evaluation results:
+
+```bash
+cd diff-edits/dashboard
+streamlit run app.py
+```
+
+The dashboard provides:
+
+- **Model Performance Comparison**: Side-by-side comparison of success rates, latency, and costs
+- **Interactive Charts**: Success rate trends, latency vs cost analysis, and performance metrics
+- **Detailed Drill-Down**: Individual result analysis with file content viewing
+- **Run Selection**: Browse and compare different evaluation runs
+- **Real-time Updates**: Automatically refreshes with new evaluation data
+
+#### Dashboard Features
+
+1. **Hero Section**: Overview of current run with key metrics
+2. **Model Cards**: Performance cards with grades and detailed metrics
+3. **Comparison Charts**: Interactive Plotly charts for visual analysis
+4. **Result Explorer**: Detailed view of individual test results including:
+   - Original and edited file content
+   - Raw model output
+   - Parsed tool calls
+   - Timing and cost metrics
+   - Error analysis
+
+#### Quick Start Dashboard
+
+```bash
+# Run a quick evaluation
+node cli/dist/index.js run-diff-eval \
+  --model-ids "anthropic/claude-3-5-sonnet-20241022,x-ai/grok-beta" \
+  --max-cases 4 \
+  --valid-attempts-per-case 2 \
+  --verbose
+
+# Launch dashboard to view results
+cd diff-edits/dashboard && streamlit run app.py
+```
+
+### Legacy Results
+
+For backward compatibility, results are also saved as JSON files in the `diff-edits/results/` directory. The JSON results include:
+- Success/failure status
+- Extracted tool calls
+- Diff edit content
+- Token usage and cost metrics
+
 ## Metrics

+# A Note on Cline's Diff Evaluation Setup
+
+Hey there, this note explains what we're doing with Cline's diff evaluation (evals) system. It's all about checking how well various AI models (which users connect to Cline via their own API keys), prompts, and diffing tools can handle file changes.
+
+## What We're Trying to Figure Out
+
+The main idea here is to figure out which AI models (configured by users) are best at making `replace_in_file` tool calls that work correctly. This helps us understand model capabilities and also speeds up our own experiments with prompts and diffing algorithms to make Cline better over time. We want to know a few key things.
+
+First, can the model create diffs, which are just sets of SEARCH and REPLACE blocks, that apply cleanly to a file? This is what we call `diffEditSuccess`.
+
+Second, how do different LLMs, like Claude or Grok, stack up against each other when they try to make these diff edits? We use a standard set of real-world test cases for this.
+
+Third, do different system prompts, say our `basicSystemPrompt` versus the `claude4SystemPrompt`, change how well a model does at diff editing?
+
+Fourth, we're also looking at different ways to apply the diffs themselves. We have a few algorithms like `constructNewFileContentV1`, `V2`, and `V3`, and we want to see which ones are more robust when fed model-generated diffs.
+
+Fifth, we track how fast the model starts making an edit. The `timeToFirstEditMs` metric gives us a hint about how quickly a user would see changes happening in their editor.
+
+And finally, we keep an eye on how many tokens are used and what it costs for each model and each try. This helps us compare how efficient they are.
+
+Right now, these evals are mostly about whether the diff *applies* correctly. That means, do the SEARCH blocks find a match, and can the REPLACE blocks be put in without an error? We're not yet deeply analyzing if the change is valid code or matches what the user *wanted* semantically. That's a problem for another day, and will require a lot more scaffolding.
+
+## How We Run These Tests
+
+Two prerequisites:
+
+1. Make sure you have an `evals/.env` file with `OPENROUTER_API_KEY=<your-openrouter-key>` 
+
+2. Make sure you add a `evals/diff-edits/cases` folder with all the conversation jsons prior to running this. 
+
+
+Our testing strategy is based on replaying situations from actual user sessions where diff edits were tried.
+
+It starts with our test cases. Each one is a JSON file in `./cases` that has the conversation history that led to a diff edit, the original file content and its path, and the info needed to rebuild the system prompt from that original session.
+
+Then, for every test run, we set up a specific configuration. This includes which LLM we're testing, which system prompt it gets, which function we use to parse the model's raw output, and which function we use to actually apply the diff. Here's the command I've been using:
+
+```bash
+npm run diff-eval -- --model-ids "anthropic/claude-3-5-sonnet-20241022,x-ai/grok-3-beta" --max-cases 4 --valid-attempts-per-case 2 --verbose --parallel
+```
+
+This will build the eval script, run it, and then open the streamlit dashboard to show the results.
+
+The `TestRunner.ts` script is the main coordinator. For each test case and setup, `ClineWrapper.ts` takes over and sends the conversation and system prompt to the LLM. We then watch the model's response as it streams in and parse it to find any tool calls.
+
+We're specifically looking for the model to make a single `replace_in_file` tool call. Multiple edits in one tool call are allowed, and recorded (in case you want to filter results by number of edits in a single tool call and compare success rate for that slice across different models/system prompts/etc). If it does, and it's for the correct file, we grab the diff content it produced. Then, the chosen diff application algorithm tries to apply that diff to the original file. We record whether this worked or not as `diffEditSuccess`.
+
+We record a bunch of data for every attempt into a database. This includes details about the model and prompt, token counts, costs, the raw output from the model, the parsed tool calls, whether it succeeded or failed, any error messages, and timing info. For a detailed explanation of the database schema, see [database.md](./database.md).
+
+A big part of this is how we handle "valid attempts," which I'll explain next.
+
+## Keeping it Fair with "Valid Attempts"
+
+LLMs can be unpredictable. If we replay an old scenario, a new model, or even the same model later, might do something completely different than what happened originally. It might call another tool or ask a question instead of trying a diff edit.
+
+Since we really want to test the *diff editing* part, we need a way to make sure we're comparing fairly. That's why we have this idea of "valid attempts."
+
+An attempt is "valid" for this benchmark if the model actually tries to do what we're interested in. This means two things. One, it must call the `replace_in_file` tool. Two, it must target the *same file path* that was targeted in the original recorded conversation for that test case.
+
+If the model does something else, like calling a different tool or picking the wrong file, we don't count that attempt against its diff editing score. Instead, we consider it an "invalid attempt" for *this specific benchmark* and simply re-run that test case with that model. We keep doing this until we've collected a set number of these "valid attempts."
+
+For example, if we ask for 5 valid attempts per test case, the system will keep re-rolling for that case until the model has tried to edit the correct file using the `replace_in_file` tool 5 times. Only then do we look at how many of those 5 valid attempts actually resulted in a successful diff application (`diffEditSuccess`).
+
+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
+
+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.
+
+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.

+# Diff Edit Evaluation Database Schema
+
+This document provides an overview of the SQLite database schema used for the diff edit evaluation suite. The database is designed to capture every aspect of the evaluation runs in a structured way, allowing for detailed, multi-dimensional analysis and ensuring full reproducibility of our findings.
+
+## Data Model Overview
+
+The database is composed of several interconnected tables that work together to provide a comprehensive picture of each evaluation. The core of the model revolves around `runs`, `cases`, and `results`.
+
+### `runs`
+
+A `run` represents a single, top-level execution of the evaluation script (e.g., one invocation of `npm run diff-eval`). It serves as the main container for a complete benchmark session.
+
+-   **Purpose**: To group all the results from a single benchmark execution, allowing for high-level comparison between different runs over time.
+-   **Key Columns**:
+    -   `run_id`: A unique identifier for the entire run.
+    -   `description`: A human-readable summary of the run's configuration (e.g., which models were tested, how many cases, etc.).
+    -   `system_prompt_hash`: A foreign key that links this run to the specific system prompt that was used, ensuring we can track performance changes based on prompt modifications.
+
+### `cases`
+
+A `case` represents a single test scenario that is presented to a model. It corresponds to one of the JSON files in the `cases/` directory and links that static definition to a specific benchmark `run`.
+
+-   **Purpose**: To track the individual test scenarios within a given run.
+-   **Key Columns**:
+    -   `case_id`: A unique identifier for the case *within* a specific run.
+    -   `run_id`: A foreign key linking back to the parent `run`.
+    -   `task_id`: The original, persistent identifier for the test case (typically from the JSON filename).
+    -   `file_hash`: A foreign key linking to the original, un-edited file content for this case.
+
+### `results`
+
+This is the most granular and important table in the database. A `result` represents the outcome of a single attempt by a specific model on a specific case.
+
+-   **Purpose**: To store the detailed outcome of every single model attempt, providing the raw data for all quantitative and qualitative analysis.
+-   **Key Columns**:
+    -   `result_id`: The primary key for the result.
+    -   `run_id`, `case_id`, `model_id`, `processing_functions_hash`: A set of foreign keys that precisely situate this result within the context of a specific run, case, model, and set of helper functions.
+    -   `succeeded`: A boolean indicating if the generated diff was applied successfully.
+    -   `error_enum`: A numeric code representing the specific type of error if the attempt failed (e.g., `1` for `no_tool_calls`, `7` for `wrong_file_edited`).
+    -   `num_edits`, `num_lines_deleted`, `num_lines_added`: Quantitative metrics about the structure of the generated diff.
+    -   `time_to_first_token_ms`, `time_to_first_edit_ms`, `time_round_trip_ms`: High-precision timing data to measure model latency.
+    -   `cost_usd`, `completion_tokens`: Cost and token usage metrics for efficiency analysis.
+    -   `raw_model_output`, `file_edited_hash`, `parsed_tool_call_json`: The rich, qualitative data. This includes the model's full, raw response and the parsed tool calls, which are invaluable for debugging and understanding the model's reasoning.
+
+---
+
+## Supporting Tables
+
+The following tables store versioned, deduplicated content to ensure data integrity and efficiency.
+
+### `system_prompts`
+
+-   **Purpose**: Stores the versioned content of the system prompts used in evaluations.
+-   **Key Columns**:
+    -   `hash`: A unique hash of the prompt's content, which acts as the primary key. This prevents duplicate storage of the same prompt.
+    -   `name`: A human-readable name for the prompt (e.g., `basicSystemPrompt`, `claude4SystemPrompt`).
+    -   `content`: The full text of the system prompt.
+
+### `processing_functions`
+
+-   **Purpose**: Stores the versioned combinations of parsing and diff-editing functions.
+-   **Key Columns**:
+    -   `hash`: A unique hash of the function combination name.
+    -   `name`: A human-readable name (e.g., `parseV2-diffV2`).
+    -   `parsing_function`: The name of the function used to parse the model's output.
+    -   `diff_edit_function`: The name of the function used to apply the diff.
+
+### `files`
+
+-   **Purpose**: Stores the content of all files involved in the tests, including the original source files and the diffs generated by the models.
+-   **Key Columns**:
+    -   `hash`: A content-based hash of the file, ensuring that identical files are only stored once.
+    -   `filepath`: The original path of the file.
+    -   `content`: The full content of the file.
+
+## The Bigger Picture
+
+This relational schema provides a powerful foundation for sophisticated analysis. It moves beyond simple pass/fail metrics and allows us to explore the nuanced interactions between models, prompts, and the code they operate on. With this database, we can answer critical questions like:
+
+-   "How does prompt engineering affect not just success rate, but also latency and cost?"
+-   "Are certain models more prone to specific types of errors (e.g., hallucinating file paths vs. failing to call a tool)?"
+-   "Which of our internal diffing algorithms is the most robust against a wide range of model-generated edits?"
+
+Ultimately, this data model enables us to move from simply *measuring* performance to truly *understanding* it, providing the insights needed to build more capable and reliable AI engineering systems.
+
+---
+
+## Viewing the Full Schema
+
+To see the most up-to-date and detailed schema for the database, you can use the `sqlite3` command-line tool. From the `evals/diff-edits` directory, run the following command:
+
+```bash
+sqlite3 evals.db .schema
+```
+
+This will print the complete `CREATE TABLE` statements for all tables in the database, providing a definitive reference for the database structure.

+ *    - 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

+/**
+ * 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
