setup-refocus

A setup tool for clickable macOS notifications when Claude Code finishes a task. Clicking a notification brings the terminal window back to the front.

In plain words
What is it for?
Use it to configure completion notifications for iTerm2, Ghostty, or Terminal.app, including notification sounds and a test alert.
Why use it?
It removes the need to keep checking the terminal while a long coding task runs.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

setup-refocus scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (setup-refocus.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

Refocus: Never Lose Track of Your Terminal

This skill sets up clickable macOS notifications for Claude Code:

  • Notification on task completion - Know when Claude is done
  • Click to refocus - Activate your terminal window instantly
  • Smart messages - Different notifications for different completion types
  • Customizable sounds - Choose your notification sound

How to Run

Users can trigger this skill by:

  1. Slash command: /refocus:setup-refocus
  2. Ask Claude: "Set up refocus" or "I want clickable notifications when tasks complete"

What It Does

  1. Asks which terminal you use (iTerm2, Ghostty, or Terminal.app)
  2. Asks your preferred notification sound
  3. Creates the notification handler script at ~/.claude/hooks/refocus-handler.sh
  4. Configures the Stop hook in ~/.claude/settings.json
  5. Sends a test notification to confirm it works

After Setup

When Claude Code finishes a task:

  1. A notification appears in your macOS notification center
  2. Click the notification to activate your terminal window
  3. You're right back where you left off!

Requirements

  • macOS
  • terminal-notifier - Install with: brew install terminal-notifier
  • jq for settings configuration (brew install jq)

Supported Terminals

  • iTerm2 - Bundle ID: com.googlecode.iterm2
  • Ghostty - Bundle ID: com.mitchellh.ghostty
  • Terminal.app - Bundle ID: com.apple.Terminal

Customization

Changing Terminal

Re-run the setup to choose a different terminal.

Notification Sounds

Available sounds during setup:

  • Hero (recommended)
  • Glass
  • Pop
  • Submarine
  • None (silent)

Manual Configuration

The hook is configured in ~/.claude/settings.json:

{
  "hooks": {
    "Stop": [{
      "matcher": "",
      "hooks": [{
        "type": "command",
        "command": "~/.claude/hooks/refocus-handler.sh"
      }]
    }]
  }
}

Troubleshooting

Notification doesn't appear

  1. Check macOS notification settings for terminal-notifier
  2. Go to System Settings > Notifications > terminal-notifier
  3. Ensure "Allow Notifications" is enabled

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
