Rust agent runtime / local-first

Give coding agents a runtime you can trust.

Durable sessions, policy-gated tools, and local execution in one Rust harness—independent of any client or model.

01 / Durable control

One authority. No hidden state.

The daemon owns lifecycle, policy, credentials, and execution. Clients stay replaceable.

01

Durable sessions survive the client.

Disconnect, reconnect, or swap interfaces without losing the authoritative event history.

02

Policy before execution.

Every typed action resolves to deny, allow, or human approval.

DENYAPPROVEALLOW
03

References, never raw secrets.

Keychain-backed credentials stay outside events, payloads, traces, and tests.

04

Typed IPC keeps clients replaceable.

CLI, TUI, ACP, and Zap-facing paths request work; they do not own it.

request → durable event

02 / Request flow

Every action earns its outcome.

Typed requests move through a fixed control path. Unknown outcomes never become completed.

  1. 01 Client request typed request · origin=agent
  2. 02 Policy decision deny · allow · needs approval
  3. 03 Human approval explicitly accepted
  4. 04 Sandbox + capability bounded execution
  5. 05 Durable outcome stored event log

03 / Real CLI

The runtime speaks in durable events.

Create a session, prompt it, approve gated work, and replay stored history from the CLI.
