pi-rukas
Deterministic harness that runs coding agents on open-weight models, with a shell filter for saving tokens.
Overview
pi-rukas is a deterministic software harness and factory for running coding agents on open-weight models. It is built by Janni Turunen at Trail Openers.
The project pairs the pi-rukas orchestrator and its deterministic drivers with oo, a shell filter designed to save tokens during agent runs.
The orchestrator and drivers are open source under Apache-2.0 and currently in alpha. Trail Openers also offers the harness to teams on request and runs a hosted software factory app called Tehas.
Features
- Runs coding agents on open-weight models.
- Uses deterministic drivers to orchestrate agent work.
- Includes the oo shell filter for reducing token usage.
