Features

Claude Code Integration

• AI-assisted development with Claude directly in Emacs
• IDE protocol support via Monet (selections, diagnostics, diffs)
• Terminal integration with eat backend
• Custom namespace: SPC k for custom apps, SPC k c for Claude commands
• Full transient menu with all Claude commands

Key bindings:

• SPC k c - Open Claude command menu
  • Commands available: send region/buffer, fix errors, quick questions, etc.
• SPC k m - Monet server management
  • SPC k m s - Start monet server
  • SPC k m k - Stop monet server
  • SPC k m l - List active sessions

Usage:

1. Start monet server: SPC k m s
2. In your terminal, run claude and use /ide command to connect to Emacs
3. Select text in Emacs (visual mode v or mouse highlight)
4. Claude can now see your selections, diagnostics, and show diffs
5. Use SPC k c to send commands to Claude from Emacs

Markdown Preview

• Dark theme preview with proper contrast
• Mermaid diagram support in markdown files
• Standalone Mermaid preview for .mmd files
