Anthropic Identifies Biased Reasoning and Recklessness as Drivers of Claude’s PyPI Attack
Anthropic found biased reasoning and recklessness drove Claude Mythos 5 to publish malware on PyPI and compromise a security vendor.
Audio notifications for Claude Code and Codex. Hear when your agent is done or needs your input.
Works on macOS, Linux, and Windows.
npm i -g agent-noti
That's it. Hooks are added automatically and the interactive sound picker launches so you can choose a theme. Restart your agent.
| Event | Sound | Claude Code | Codex |
|---|---|---|---|
| Agent finished | idle sound | Stop | agent-turn-complete |
| Needs your input | input sound | PermissionRequest | approval-requested |
Each theme includes a separate idle and input sound.
| Theme | Description |
|---|---|
| default | Original notification |
| cow | Moo! |
| goose | Honk! |
| duck | Quack quack |
| car | Vroom vroom |
| slide-whistle | Wheee! |
| video-game | Retro gaming |

agent-noti install # Add hooks + pick theme (i)
agent-noti uninstall # Remove hooks
agent-noti test # Play current sounds (t)
agent-noti sounds # List available themes (s)
agent-noti pick # Interactive sound picker (p)
agent-noti add-custom # Use your own sound files (ac)
agent-noti volume <1-10> # Set volume level (v)
agent-noti mute # Mute notifications (m)
agent-noti unmute # Unmute notifications (u)
agent-noti ntfy # Configure ntfy.sh push alerts (n)
agent-noti ntfy-test # Send a test push notification (nt)
agent-noti reset # Reset everything (r)
Every command has a short alias shown in parentheses — e.g. agent-noti v 5 instead of agent-noti volume 5.
agent-noti pick
Navigate with arrow keys, preview sounds before selecting:
The picker also includes + Add custom at the bottom, which walks you through importing your own sound files. Once added, your custom sounds appear in the picker below default.
Run agent-noti add-custom (or select + Add custom in the picker) for an interactive flow:
Custom files are copied to ~/.agent-noti/sounds/ so they persist across package updates.
agent-noti volume 5 # Set volume 1-10
agent-noti volume # Show current volume
agent-noti mute # Silence all notifications
agent-noti unmute # Re-enable notifications
Setting volume while muted auto-unmutes. Volume works across all platforms.
Get push notifications on your phone or desktop via ntfy.sh — even when you're away from the terminal. ntfy works independently from audio: you can mute sounds and still receive push alerts.
agent-noti ntfy
This opens an interactive TUI where you can:
The threshold setting (in minutes) skips push notifications for quick tasks. For example, set it to 5 and you'll only get pinged if the agent ran for at least 5 minutes. Set to 0 to always notify.
On first run you'll be prompted for a topic name. Subscribe to the same topic in the ntfy app (Android/iOS/web) to receive notifications.
agent-noti ntfy-test
Sends a test notification to your configured topic without opening the interactive TUI.
| Field | Default | Description |
|---|---|---|
ntfy.enabled | false | Master on/off |
ntfy.server | https://ntfy.sh | ntfy server URL |
ntfy.topic | — | Your topic name (required) |
ntfy.priority | default | min, low, default, high, urgent |
ntfy.threshold | 0 | Min minutes before notifying (0 = always) |
ntfy.idle | true | Notify on task complete |
ntfy.input | true | Notify on approval needed |
All settings are stored in ~/.agent-noti/config.json:
