Jb Tuna Script

JB Tuna Script

Use this skill when creating small scripts that should appear in Tuna.

Key facts

• Tuna scans executable scripts in ~/Library/Scripts even in free mode.
• Custom script directories may be disabled unless Tuna Pro is active.
• Prefer creating the script directly in ~/Library/Scripts/<command-name>.
• Do not research Tuna script locations again unless this path fails.

Minimal script template

#!/usr/bin/env bash
# @tuna.name command-name
# @tuna.subtitle Short human-readable description
# @tuna.icon symbol:terminal
# @tuna.mode background
# @tuna.input none
# @tuna.output text

set -euo pipefail

export PATH="$HOME/.homebrew/bin:/opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin:$PATH"

exec command arg1 arg2

Workflow

1. Choose a concise filename and Tuna name, usually the command name the user asked for.
2. Write the script at ~/Library/Scripts/<name>.
3. Include Tuna metadata comments only as needed:
   • @tuna.name for display/search name.
   • @tuna.subtitle for a short explanation.
   • @tuna.icon optional; use an SF Symbol when obvious.
   • @tuna.mode background for wrappers that should just run.
   • @tuna.input none for no-argument scripts.
   • @tuna.output text when command output is useful.
4. Make it executable: chmod +x ~/Library/Scripts/<name>.
5. Verify by running ~/Library/Scripts/<name> directly.

Example: Agent Browser dashboard

#!/usr/bin/env bash
# @tuna.name browser dashboard
# @tuna.subtitle Open the Agent Browser session dashboard
# @tuna.icon symbol:rectangle.connected.to.line.below
# @tuna.mode background
# @tuna.input none
# @tuna.output text

set -euo pipefail

export PATH="$HOME/.homebrew/bin:/opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin:$PATH"

agent-browser dashboard start
open http://localhost:4848

Expected path:

~/Library/Scripts/agent-browser-dashboard

Verify that the dashboard opens at http://localhost:4848.

Guardrails

• Keep wrappers minimal; avoid inspecting unrelated existing scripts unless the requested behavior is complex.
• Use absolute/user-specific PATH entries when needed for Homebrew-installed CLIs.
• Prefer exec <command> so the script exits with the wrapped command's status.
