+# Changelog
+
+## [1.0.0] - 2026-01-29
+
+### Added
+- **AI Chat Integration**: Use `@Excel Agent` in Raycast Chat to manipulate spreadsheets with full context.
+- **Batch Execution**: The AI now groups instructions into single transactions for 3-4x faster execution.
+- **Test Connection**: Dedicated feature to verify Excel connectivity and Accessibility permissions.
+- **Built-in Scripts**: Reliability layer that uses pre-built AppleScript for common tasks (Bold, Financial Style, Borders) bypassing AI generation errors.
+- **Context Awareness**: The agent now reads "Sheet Name" and "Selection" before complying with requests.
+
+### Improved
+- **Speed**: Reduced context gathering latency by 80% (removed scanning entire used range by default).
+- **Reliability**: Rewrote AppleScript execution to using strict `tell active sheet` scoping to prevent silent failures.
+- **Error Handling**: Clearer error messages when Excel is not running or permissions are missing.
+- **UI**: Streamlined "Ask Excel" command interface with Quick Actions and History.
+
+### Fixed
+- Fixed an issue where AppleScript would run successfully but not apply changes to the active workbook.
+- Fixed timeouts on slower machines by optimizing script generation.

+# Excel Agent for Raycast
+
+Control Microsoft Excel with natural language. Ask questions, format cells, create tables, and more — all from Raycast.
+
+![Quick Actions](assets/demo-1.png)
+![AI Chat Integration](assets/demo-2.png)
+
+## Features
+
+- **Natural Language Control** — Just type what you want to do in Excel
+- **AI Chat Integration** — Use `@Excel Agent` in Raycast Chat to build complex models
+- **Quick Actions** — One-click formatting for common tasks (Financial Style, Borders, etc.)
+- **Robust & Fast** — Optimized specifically for speed and reliability on Mac
+- **Multiple AI Providers** — Works with Raycast AI, OpenAI, Google Gemini, or Anthropic Claude
+
+## Requirements
+
+- **macOS** — Uses AppleScript to control Excel
+- **Microsoft Excel** — Must be installed and running
+- **Raycast v1.104.3+**
+
+## Setup
+
+### 1. Install the Extension
+
+Install from the Raycast Store or build from source.
+
+### 2. Grant Accessibility Permissions
+
+The first time you run a command, macOS will ask you to grant Raycast Accessibility permissions:
+
+1. Open **System Settings** → **Privacy & Security** → **Accessibility**
+2. Add and enable **Raycast**
+
+### 3. Configure AI Provider
+
+Open the extension preferences and choose your AI provider:
+
+| Provider | Setup Required |
+|----------|---------------|
+| **Raycast AI** | Raycast Pro subscription |
+| **OpenAI** | API key from [platform.openai.com](https://platform.openai.com) |
+| **Google Gemini** | API key from [Google AI Studio](https://makersuite.google.com) |
+| **Anthropic Claude** | API key from [console.anthropic.com](https://console.anthropic.com) |
+
+## Usage
+
+### 1. AI Chat (@Excel Agent)
+
+The most powerful way to use this extension. In Raycast AI Chat, type **@Excel Agent** followed by your request:
+
+- *"Create a DCF model template with assumptions for revenue growth and WACC"*
+- *"Analyze this data and format the outliers in red"*
+- *"Build a sales table for Q1-Q4 and add a Total column"*
+
+The agent will intelligently break down tasks, write data, format cells, and confirm actions.
+
+### 2. "Ask Excel" Command
+
+Quickly execute single commands or apply presets:
+
+- **Quick Actions** — Instant formatting (Financial Style, Bold Headers, Currency, etc.)
+- **Recent Commands** — Your history of custom commands
+- **Custom Command** — Type one-off instructions like *"Make A1:E1 bold"*
+
+### 3. "Read Excel" Command
+
+Quickly view the current selection and sheet information without leaving Raycast.
+
+## Tips
+
+- **Be specific** — Instead of "make it bold", try "make row 1 bold"
+- **Combine actions** — "Bold headers and add borders to used range"
+- **Use Quick Actions** — They're instant and don't require AI
+- **Check Excel is running** — The extension will remind you if Excel isn't open
+
+## Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| "Excel not running" | Open Microsoft Excel with a workbook |
+| "Accessibility permissions" | Add Raycast to System Settings → Privacy & Security → Accessibility |
+| "No workbook open" | Open or create an Excel file |
+| AI not responding | Check your API key in preferences |
+
+## Privacy
+
+- Your Excel data stays on your Mac
+- AI providers only receive the minimal context needed (sheet name, selection address)
+- No data is stored on external servers by this extension
