# Phase 15: Autonomous Systems

> Agents that run without human intervention, safely.

## Start this phase on GitHub

**Prerequisites:** Phase 14 Lesson 01, The Agent Loop.

**First lesson:** [Long-Horizon Agents](01-long-horizon-agents/)

Run this command from the repository root:

```bash
python3 phases/15-autonomous-systems/01-long-horizon-agents/code/main.py
```

Keep the command, exit code, horizon projection, compounded reliability table,
and one operational control you would require before a long run.

**Next action:** Recalculate one trajectory with a different per-step
reliability, then continue to [Self-Taught Reasoning](02-star-family-reasoning/).

Browse the [full Phase 15 lesson list](../../README.md#phase-15) or the
[cross-phase roadmap](../../ROADMAP.md).
