iterm-notify

A notification script for Claude Code that reacts when the agent needs attention or has finished. It works with iTerm2, a macOS terminal app.

In plain words
What is it for?
Use it to bounce the iTerm2 dock icon, show a terminal badge, send macOS notifications, and clear the badge when Claude Code stops.
Why use it?
It lets you notice agent activity without repeatedly checking the terminal window.

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

iterm-notify 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 3d ago.

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.

What it actually says

iterm-notify

Provides notify.sh — a hook script that fires on Claude Code Notification and Stop events.

Not a slash command. Wire it in ~/.claude/settings.json — see README.

What it does

On Notification (Claude needs attention):

  • Bounces the iTerm2 dock icon once
  • Sets an iTerm2 badge: <topic> ⚡ (or just if no topic file)
  • Sends a macOS desktop notification via terminal-notifier with a click-to-focus action

On Stop (Claude finished):

  • Clears the iTerm2 badge

Prerequisites

  • macOS with iTerm2
  • terminal-notifier: brew install terminal-notifier
  • jq: brew install jq

Wiring

See README for setup instructions.

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.

iterm-notify is a skill published in the GitHub repository harnessprotocol/harness-kit (10 stars, last pushed 4d ago), licensed Apache-2.0. It adds 38 tokens to every session and 237 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
