+# Browser Tools for Claude
+
+This package provides a set of tools that allow Claude to control a headless
+Chrome browser from Go. The tools are built using the
+[chromedp](https://github.com/chromedp/chromedp) library.
+
+## Available Tools
+
+1. `browser_navigate` - Navigate to a URL and wait for the page to load
+2. `browser_click` - Click an element matching a CSS selector
+3. `browser_type` - Type text into an input field
+4. `browser_wait_for` - Wait for an element to appear in the DOM
+5. `browser_get_text` - Get the text content of an element
+6. `browser_eval` - Evaluate JavaScript in the browser context
+7. `browser_screenshot` - Take a screenshot of the page or a specific element
+8. `browser_scroll_into_view` - Scroll an element into view
+
+## Usage
+
+```go
+// Create a context
+ctx := context.Background()
+
+// Register browser tools and get a cleanup function
+tools, cleanup := browse.RegisterBrowserTools(ctx)
+defer cleanup() // Important: always call cleanup to release browser resources
+
+// Add tools to your agent
+for _, tool := range tools {
+    agent.AddTool(tool)
+}
+```
+
+## Requirements
+
+- Chrome or Chromium must be installed on the system
+- The `chromedp` package handles launching and controlling the browser
+
+## Tool Input/Output
+
+All tools follow a standard JSON input/output format. For example:
+
+**Navigate Tool Input:**
+```json
+{
+  "url": "https://example.com"
+}
+```
+
+**Navigate Tool Output (success):**
+```json
+{
+  "status": "success"
+}
+```
+
+**Tool Output (error):**
+```json
+{
+  "status": "error",
+  "error": "Error message"
+}
+```
+
+## Example Tool Usage
+
+```go
+// Example of using the navigate tool directly
+navTool := tools[0] // Get browser_navigate tool
+input := map[string]string{"url": "https://example.com"}
+inputJSON, _ := json.Marshal(input)
+
+// Call the tool
+result, err := navTool.Run(ctx, json.RawMessage(inputJSON))
+if err != nil {
+    log.Fatalf("Error: %v", err)
+}
+fmt.Println(result)
+```
+
+## Screenshot Storage
+
+The browser screenshot tool has been modified to save screenshots to a temporary directory and identify them by ID, rather than returning base64-encoded data directly. This improves efficiency by:
+
+1. Reducing token usage in LLM responses
+2. Avoiding encoding/decoding overhead
+3. Allowing for larger screenshots without message size limitations
+
+### How It Works
+
+1. When a screenshot is taken, it's saved to `/tmp/sketch-screenshots/` with a unique UUID filename
+2. The tool returns the screenshot ID in its response
+3. The web UI can fetch the screenshot using the `/screenshot/{id}` endpoint
+
+### Example Usage
+
+Agent calls the screenshot tool:
+```json
+{
+  "id": "tool_call_123",
+  "name": "browser_screenshot",
+  "params": {}
+}
+```
+
+Tool response:
+```json
+{
+  "id": "tool_call_123",
+  "result": {
+    "id": "550e8400-e29b-41d4-a716-446655440000"
+  }
+}
+```
+
+The screenshot is then accessible at: `/screenshot/550e8400-e29b-41d4-a716-446655440000`
