## ✨ Features

- 🔍 **Natural Language Email Search** - Search your inbox using plain English
- 📧 **Executive Style Profiles** - Drafts match recipient's communication style
- 🎯 **Context-Aware Responses** - Uses full email threads for context
- 📤 **One-Click Publishing** - Create drafts directly in Outlook
- 🚀 **One-Time Setup** - Configure once, use in any Claude Code conversation

## 🎭 Executive Profiles

The plugin automatically matches recipients to communication styles:

- **Charles Lamanna** - Conversational-professional, strategic, engaging
- **Nirav Shah** - Action-oriented, decisive, technical, timeline-focused
- **Robert Bruckner** - Direct, data-driven, strategic, analytical
- **James Oleinik** - Collaborative, balanced, team-focused, thoughtful

Unknown recipients use a professional default style.

## 🚀 Quick Start

### Prerequisites

- Python 3.8+
- Claude Code CLI installed
- Agent 365 account with email access
- Microsoft 365 mailbox

### Installation (2 commands!)

1. **Clone and install**
   ```bash
   git clone https://github.com/jamesol-msft/claude-email-draft-plugin.git
   cd claude-email-draft-plugin
   pip install -r requirements.txt
   python setup.py
   ```

2. **Restart Claude Desktop/CLI**

That's it! The setup script automatically:
- ✅ Installs MCP proxy to your home directory
- ✅ Installs skill to `~/.claude/skills/email-draft/`
- ✅ Configures Claude Desktop MCP server
- ✅ Provides token setup instructions

### Token Setup (Optional - for real email access)

For testing without a real token, the plugin works in mock mode by default. For real email access:

```bash
# If you have get_agent365_token.py
python get_agent365_token.py

# Or create a mock token for testing
mkdir -p ~/.agent365
cat > ~/.agent365/auth-token.json << 'EOF'
{
  "access_token": "mock_token_for_testing",
  "token_type": "Bearer",
  "expires_in": 3600,
  "expires_at": 9999999999
}
EOF
```

### Verify Setup

```bash
python verify_setup.py
```

This checks that everything is configured correctly.

## 📖 Usage

### Interactive Mode
```bash
/email-draft
```
Prompts you for email context.

### Search First
```bash
/email-draft --search "recent unread from john"
```
Searches emails, lets you pick one, generates draft.

### Reply to Specific Email
```bash
/email-draft --reply-to AAMkAGI2TGAA=
```
Generates reply to email with specific ID.

### Example Workflow

1. Search for an email:
   ```bash
   /email-draft --search "latest from charles lamanna"
   ```

2. Claude searches and displays results

3. Select an email from the results

4. Review the generated draft

5. Optionally publish to Outlook drafts folder

## 🏗️ Architecture

```
Claude Code
    ↓ (MCP protocol - JSON-RPC 2.0 over stdio)
agent365_mcp_proxy.py
    ↓ (HTTPS)
Agent 365 Mail Server
    ↓ (Microsoft Graph API)
Microsoft 365 (Outlook)
```

**Key Components:**
- **MCP Proxy** (~550 lines Python) - Lightweight bridge between Claude Code and Agent 365
- **Skill File** (~830 lines Markdown) - Executive profiles and workflow logic
- **Configuration** - Simple JSON config for Claude Desktop

## 🔧 MCP Tools

The proxy exposes 3 tools to Claude Code:

| Tool | Purpose | Typical Latency |
|------|---------|-----------------|
| `search_messages` | Search emails with natural language | 30-90s |
| `get_message` | Retrieve full email details by ID | 1-3s |
| `create_draft` | Create draft in Outlook | 1-3s |

- **[TROUBLESHOOTING.md](TROUBLESHOOTING.md)** - Common issues and solutions
- **[TOKEN_CONFIGURATION.md](TOKEN_CONFIGURATION.md)** - Token management and security
- **[IMPLEMENTATION_COMPLETE.md](IMPLEMENTATION_COMPLETE.md)** - Technical implementation details

## 🔒 Security

- Tokens stored locally (`~/.agent365/auth-token.json`)
- Tokens expire after 1 hour (manual refresh required)
- No credentials in config files
- All communication over HTTPS
- MCP proxy runs locally (no external services)

## 🐛 Troubleshooting

### Token expired (401 error)
```bash
# Refresh your Agent 365 token
python get_agent365_token.py
```

### Proxy not starting
- Check Python version: `python --version` (need 3.8+)
- Check file path in `claude_desktop_config.json`
- Check Claude Code logs: View → Developer → Toggle Developer Tools

### Skill not appearing
- Verify file location: `~/.claude/skills/email-draft/SKILL.md`
- Restart Claude Code
- Check for syntax errors in SKILL.md

See [TROUBLESHOOTING.md](TROUBLESHOOTING.md) for more solutions.
