What problem does it solve?
It solves the problem of exploring a large optimization/search space without manual babysitting by autonomously iterating on code changes, evaluating them with a fixed harness, and keeping only improvements.
Core Features & Use Cases
- Karpathy-style autonomous loop: iteratively edits a single mutable file, runs a deterministic evaluation harness, and commits or reverts changes based on results.
- Plateau-triggered web search: detects consecutive discards/crashes and switches to a web-search-augmented prompt to break through knowledge ceilings.
- Budgeted, provider-flexible orchestration: runs with claude, codex, or pi providers using per-iteration budget caps and stop conditions.
- Git as state machine: improvement advances history while regressions reset hard, keeping a clean experimental trail.
Quick Start
Prepare a fleet root directory with fleet.json and a NEVER STOP program.md, then run: launch.sh <fleet-root> to start the autonomous overnight optimization loop.
