Homebrew: brew install mylee04/tools/code-notify

npm: npm install -g code-notify

Desktop notifications for AI coding tools - get alerts when tasks complete or input is needed.

Code-Notify can now watch Codex and Claude usage limits and tell you when tokens are back.

• Daily reset: Codex token daily limit reset
• Weekly reset: Codex token weekly limit reset
• Low-usage warnings: 20% and 10% remaining
• Delivery options: desktop notification, voice, sound, Slack, or Discord

Voice samples: Daily reset · Weekly reset

cn usage setup --watch
cn usage status

cn usage setup --watch enables usage alerts, turns on distinct reset voice/sound, and starts a background watcher.

• One-command usage setup: cn usage setup --watch configures Codex/Claude usage alerts and starts the background watcher
• Background usage watcher: macOS/Linux users can start, stop, restart, and inspect usage watching with cn usage watch ...
• Usage alert docs: README now shows the terminal setup flow and Slack/Discord reset alert routing

• Multi-tool support - Claude Code, OpenAI Codex, Google Gemini CLI
• Works everywhere - Terminal, VSCode, Cursor, or any editor
• Cross-platform - macOS, Linux, Windows
• Native notifications - Uses system notification APIs
• macOS click-through control - Choose which app notification clicks activate
• Sound notifications - Play custom sounds on task completion
• Voice announcements - Hear when tasks complete (macOS, Windows)
• Slack/Discord delivery - Mirror notifications to incoming webhooks
• Usage alerts - Opt-in Codex/Claude 20%, 10%, and reset notifications
• Tool-specific messages - "Claude completed the task", "Codex completed the task"
• Project-specific settings - Different configs per project
• Quick aliases - cn and cnp for fast access

macOS (Homebrew)

brew tap mylee04/tools
brew install code-notify
cn on

macOS (Homebrew, Already Installed)

cn update
code-notify version

If you were using the older claude-notify hook layout, supported upgrades now repair those Claude hooks automatically. On Windows, that repair also covers older notify.ps1 hook layouts and alternate Claude settings locations such as %USERPROFILE%\.config\.claude\settings.json. Existing unrelated Claude hooks are preserved during enable/disable operations.

Linux / WSL

curl -sSL https://raw.githubusercontent.com/mylee04/code-notify/main/scripts/install.sh | bash

npm (macOS / Linux / Windows)

npm install -g code-notify
cn on

Windows

irm https://raw.githubusercontent.com/mylee04/code-notify/main/scripts/install-windows.ps1 | iex

Paste this to your AI coding agent (Claude Code, Codex, Cursor, Gemini CLI, etc.):

Install code-notify using npm only. Prefer npm over curl or git clone.

npm install -g code-notify
cn on all
cn test
cn status

Expected result:

• cn test shows a desktop notification.
• cn status shows enabled tools.

If npm is unavailable, use the fallback installer in docs/installation.md.

Agent-friendly command block:

npm install -g code-notify
cn on all
cn test

npm packages are published with GitHub Actions Trusted Publisher and npm provenance. The npm postinstall script only performs global-install bootstrap tasks: on macOS/Linux it quietly repairs legacy Claude hook paths, and on Windows it bootstraps the local PowerShell wrapper. Set CODE_NOTIFY_SKIP_POSTINSTALL=1 to skip those install-time helpers.

When enabling project notifications with cnp on, Code-Notify warns if Claude project trust does not appear to be accepted yet. Project-scoped Claude hooks override the global mute file, so cn off will not suppress a project where cnp on is enabled. all is also accepted as an explicit alias for global commands such as cn on all, cn off all, and cn status all.

Code-Notify uses the hook systems built into AI coding tools:

• Claude Code: ~/.claude/settings.json
• Codex: ~/.codex/config.toml
• Gemini CLI: ~/.gemini/settings.json

For Codex, Code-Notify configures notify = ["/absolute/path/to/notifier.sh", "codex"] and reads the JSON payload Codex appends on completion. Codex currently exposes completion events through notify; approval and request_permissions prompts do not currently arrive through this hook.

When enabled, it adds hooks that call the notification script when tasks complete:

{
  "hooks": {
    "Stop": [
      {
        "matcher": "",
        "hooks": [{ "type": "command", "command": "notify.sh stop claude" }]
      }
    ],
    "Notification": [
      {
        "matcher": "idle_prompt",
        "hooks": [
          { "type": "command", "command": "notify.sh notification claude" }
        ]
      }
    ],
    "SubagentStop": [
      {
        "matcher": "",
        "hooks": [
          { "type": "command", "command": "notify.sh SubagentStop claude" }
        ]
      }
    ]
  }
}

By default, notifications only fire when the AI is idle and waiting for input (idle_prompt). You can customize this:

cn alerts                          # Show current config
cn alerts add permission_prompt    # Also notify on tool permission requests
cn alerts add ask_user             # Notify immediately when Claude asks a question
cn alerts add SubagentStop         # Also notify when Claude subagents finish
cn alerts remove permission_prompt # Remove permission notifications
cn alerts reset                    # Back to default (idle_prompt only)

Alert-type matching applies to Claude Code notification hooks and Gemini CLI notification hooks. ask_user is a Claude-only PreToolUse hook for AskUserQuestion; it is applied immediately when Claude notifications are already enabled. Claude Code agent/team events are separate hook events and are opt-in via cn alerts add SubagentStop, cn alerts add TeammateIdle, or cn alerts add TaskCompleted.

Agent-team and subagent workflows can be noisy if permission_prompt is enabled. If you only want idle pings, run cn alerts remove permission_prompt && cn on. Codex currently uses completion events from notify, so permission_prompt and idle_prompt settings do not change Codex behavior.

Code-Notify can also send the same notification to Slack or Discord through incoming webhooks. Desktop notifications still work normally; remote delivery is an extra channel.

cn channels add slack https://hooks.slack.com/services/...
cn channels add discord https://discord.com/api/webhooks/...
cn channels status
cn channels test all

Webhook URLs are stored locally in ~/.config/code-notify/channels.json and are redacted in cn status.

Usage alerts are opt-in for Codex and Claude. Fast setup:

cn usage setup --watch
cn usage status

That enables usage alerts, sets the default 20% and 10% warning thresholds, enables distinct reset voice/sound, and starts a background watcher.

Manual setup:

cn usage on                         # Enable usage alerts
cn usage thresholds set 20,10       # Warn at 20% and 10% remaining
cn usage reset-alerts voice on      # Speak reset alerts
cn usage reset-alerts sound default # Use the reset sound
cn usage check                      # Run one check now
cn usage watch start --interval 300 # Keep watching in the background

Code-Notify checks the daily (5h) and weekly (7d) usage windows. It sends a warning when remaining usage crosses 20% or 10%, and sends a reset notification when a window returns to 100%.

cn usage check runs once and exits. cn usage watch start keeps watching in the background on macOS/Linux. Use cn usage watch stop to stop it.

Terminal demo:

cn usage setup --watch
cn usage status

Reset alerts are intentionally separate from normal task-complete alerts. By default they use a different title, voice message, and reset sound so it is clear that tokens have refilled. The voice message identifies the window, for example Codex token daily limit reset or Codex token weekly limit reset. You can disable or customize that behavior:

cn usage reset-alerts off
cn usage reset-alerts voice off
cn usage reset-alerts sound set ~/sounds/tokens-reset.wav

Send reset alerts to Slack or Discord too:

cn channels add slack https://hooks.slack.com/services/...
cn channels add discord https://discord.com/api/webhooks/...
cn channels test all

Codex usage checks read ~/.codex/auth.json. Claude usage checks read ~/.claude/.credentials.json. Code-Notify does not launch provider CLIs or start login flows. Background watching starts only when you run cn usage setup --watch or cn usage watch start.

Command not found?

exec $SHELL   # Reload shell

No notifications?

cn status     # Check if enabled
cn test       # Test notification
brew install terminal-notifier  # Better notifications (macOS)

Notification click opens the wrong macOS app?

cn click-through add PhpStorm
cn test

Installed with npm?

cn update     # Runs: npm install -g code-notify@latest

Too many last_notification_* files in ~/.claude/notifications?

Generated rate-limit state files are stored under ~/.claude/notifications/state/ instead of cluttering the root notifications folder.
