Try it
Press the button. Watch what happens.
Activation sealed in the record
Every tool call waits until you say go
What it stops
Everything running. And it reports what it could not.
A stop you can see is a stop you can trust. So the Kill Switch reports as carefully as it acts.
Agents
While the switch is engaged, every tool call an agent tries is refused.
Workflows
Running chains and research jobs stop.
What it could not reach
If a part of the system cannot answer, the Kill Switch names it, so a silent part never reads as all clear.
The record
The stop itself is sealed as its own signed record: when, which mode, and why.
Two modes
Graceful exit. Or hard stop.
Soft
Finish the step, then stop
The current action completes, then everything stops. Use it when a clean finish matters more than a fast one.
- Current step finishes
- Clean shutdown
- Sealed in the record
Hard
Immediate termination
Everything stops now. Work in flight is abandoned rather than finished. This is the mode Cmd+Shift+K uses.
- Immediate
- No graceful wait
- Sealed in the record
Guarantees
What you can count on from the Kill Switch.
Built into every install
It ships inside the Mac app, always on.
Ranks above every agent
Agents, commands, and policies all yield to it.
Checked on every tool call
While it is engaged, each tool call is refused.
Works if the interface fails
Cmd+Shift+K runs outside the main interface, so a frozen screen still stops.
Sealed in the record
Every activation creates its own signed Capsule.
Honest about its reach
Anything it could not reach is named, and counted apart from what stopped.
