Quick Reference

Profiles

Profiles are templates for spawning terminals with saved settings (theme, font, directory, startup command).

To create a profile:

1. Open Settings (⚙️) → Profiles tab
2. Click "Add Profile"
3. Set name, category, theme, font size
4. Optional: working directory (empty = inherits from header)
5. Optional: startup command (e.g., lazygit, htop)

Key features:

• Smart directory inheritance from header
• Categories with 9 colors (collapsible)
• Import/Export as JSON
• Drag-drop reordering in dashboard

Integration

Spawn API - Create terminals programmatically:

TOKEN=$(cat /tmp/tabz-auth-token)
curl -X POST http://localhost:8129/api/spawn \
  -H "Content-Type: application/json" \
  -H "X-Auth-Token: $TOKEN" \
  -d '{"name": "Worker", "workingDir": "~/projects", "command": "claude"}'

Custom triggers - Add to any HTML element:

<button data-terminal-command="npm run dev">Start Dev</button>

For full API documentation, read references/api-endpoints.md.

MCP Tools

20 tools for browser automation: screenshots, clicks, downloads, network capture.

Quick example:

mcp-cli info tabz/tabz_screenshot       # Check schema first
mcp-cli call tabz/tabz_screenshot '{}'  # Capture viewport

For complete tool reference, read references/mcp-tools.md.

Debugging

Essential commands:

ps aux | grep "node server.js" | grep -v grep  # Backend running?
tmux ls | grep "^ctt-"                          # List terminals
curl http://localhost:8129/api/health           # Health check

For common issues and solutions, read references/debugging.md.

Audio/TTS

Neural text-to-speech notifications for Claude Code status changes. Audio generated via edge-tts, played through Chrome.

Key settings (Settings → Audio):

• Voice: 10 neural voices, or "Random" for unique voice per terminal
• Rate: Speech speed (-50% to +100%)
• Pitch: Voice pitch (-200Hz to +300Hz) - higher = more urgent
• Events: Ready, session start, tools, subagents, context warnings

Context alerts auto-elevate pitch + rate:

• 50% warning: +100Hz, +15% rate
• 75% critical: +200Hz, +30% rate

API example:

curl -X POST http://localhost:8129/api/audio/generate \
  -H "Content-Type: application/json" \
  -d '{"text": "Task complete", "pitch": "+20Hz"}'
