Agentic Control Tower
Open source · Mobile betaThe signing authority for the entire suite.
ACT is the control tower — the single, irreducible authority every other product routes through. It's where privileged actions are gated, where clearances are cryptographically signed, and where you approve or deny, from your phone.
// Sequence
How it works
An agent requests a clearance for a specific action.
ACT classifies the action's risk and routes an approval to your device.
You approve with a tap — your phone signs the clearance with a hardware-backed key.
The requesting product verifies the signed clearance before it acts. No valid clearance, no action.
Every request and decision is recorded.
