Agent OS Stack

The stack

10 Rust crates, 500+ tests. A control-theory-native ecosystem for autonomous software development.

01

Symphony

Orchestration

Dispatch, lifecycle, and hook management for coding agents across issue trackers.

02

Control Kernel

Governance & safety

Typed setpoints, safety shields, and multi-rate control loops that keep agents bounded.

03

Autoany

Recursive improvement

Evaluator-Governed Recursive Improvement (EGRI) — safe, measurable, rollback-capable optimization.

04

aiOS

Agent OS kernel

The contract layer — state, memory, tools, and event taxonomy for agent runtimes.

05

Arcan

Runtime

Production runtime implementing the aiOS kernel contract.

06

Lago · Vigil · Praxis

Infrastructure

Durable persistence, OpenTelemetry-native observability, and canonical tool execution.

Rocket Simulation Meets Recursive Improvement

We turned OpenRocket into a headless simulation engine, built a CLI tool, and ran 144 EGRI optimization trials in 5 minutes. Here is what we learned about mutation surfaces.

Autonomy is governance

The degree of autonomy you can grant an agent is directly proportional to the quality of your governance infrastructure.

Harness over prompting

Prompt quality matters, but harness quality is what keeps agent outputs reliable once stakes increase.
