Tribble

A Claude Code plugin that spawns Claude code sessions in new terminal tabs.

You: "Spawn claude sessions for auth, payments, and docs"

✓ Created 'Auth'
✓ Created 'Payments'
✓ Created 'Docs'

Three Claude sessions running in parallel with proper context. Like tribbles multiplying.

Install

curl -fsSL https://raw.githubusercontent.com/fractional-ai/tribble/main/install.sh | bash

Restart Claude Code after installing. To skip approval prompts, add Bash(~/.claude/plugins/tribble/scripts/*) to your allowed permissions in ~/.claude/settings.json.

Usage

Tell Claude what you want to spawn using natural language:

"Spawn a claude session for the auth refactor"
"Start three tabs: frontend, backend, and test watcher"
"Open claude to work on tests"

Or use the slash command directly:

/tribble:spawn open claude to refactor the auth module
/tribble:spawn npm run dev, npm test --watch

When spawning Claude sessions, the new session receives context about what you're working on.

Supported Terminals

Platform	Terminals
macOS	iTerm2, Terminal.app, Ghostty, Kitty, Alacritty, tmux
Linux	GNOME Terminal, Kitty, Alacritty, tmux
Windows (WSL)	Windows Terminal, Kitty, Alacritty, tmux

Kitty requires remote control enabled in ~/.config/kitty/kitty.conf:

allow_remote_control yes

For unsupported terminals (VS Code integrated terminal, etc.), run inside tmux:

tmux new-session -s work

Troubleshooting

Problem	Fix
"Not authorized to send Apple events"	System Preferences → Security → Automation → Enable
Tabs don't spawn	find ~/.claude/plugins/tribble/scripts -name "*.sh" -exec chmod +x {} \;
"Not in a tmux session"	Start tmux first: tmux new-session -s work

Run ./scripts/validate-installation.sh to diagnose issues.
