Waiting
See when an agent is paused for an answer or approval.
AI AGENT NOTIFICATIONS
Know when an AI agent needs you.
Let the agent run in the background. Your mascot changes when work is ready, blocked, interrupted, or asking for attention.

NEEDS ATTENTIONYour agent needs youOpen the right session.
ATTENTION WITHOUT SURVEILLANCE
Stop watching the terminal.
Masko listens to supported local agent events and turns them into a visible state, a notification, and a route back to the source.
Done
Return when a task finishes instead of checking repeatedly.
Error or interruption
Notice when the work stopped for a reason other than completion.
Three parts of a useful notification.
A message alone is not enough. You need context and a way back.
Source
The notification names the agent that produced the event.
Meaning
The mascot and copy distinguish waiting, done, and failure.
Return
Open or focus the related agent surface when action is required.
Built for coding-agent attention.
The feature is useful because it follows real agent lifecycle events, not a generic timer.
Session-aware
Events remain connected to the session that generated them where the agent exposes identity.
Mascot reaction
The character can visibly work, wait, ask, celebrate, or show an error.
Native notifications
Use familiar macOS attention alongside the persistent character state.
TRY IT
Your mascot keeps watch over your AI agents.

Claude Code: answer supported hook permission prompts through the mascot.
Interactive preview. No commands run.THE LITTLE DETAILS
A few questions.
we were hoping you’d ask.
Which agents can send notifications to Masko?
Claude Code, Claude Cowork, Codex, Cursor, Grok Build, Kimi Code, and Hermes Agent are the current supported set.
Will I receive a notification for every tool call?
Masko focuses user-facing attention on meaningful lifecycle and interaction moments instead of treating every internal event as urgent.
Can I return to the correct session?
Masko uses available terminal or app-focus information to return you to the relevant agent surface.
Does this work when the terminal is behind other windows?
Yes. The mascot and macOS notification surface remain visible outside the terminal.
Which Macs can run Masko?
Masko supports macOS 14 or newer.
