Don't Just Upgrade the Model: Dev Open-Sources Control Harness for AI Coding Agents
Zestyclose_Music_409 · reddit · 2026-08-09
After heavily using AI coding agents, a developer found that failures often occur not within the model itself, but in the control system around it (e.g., making unsanctioned decisions, forgetting context, lacking verification). To solve this, he built Escapement, a repository-native harness.
The core philosophy is to 'upgrade how the model works, not the model.' The system follows a Specify → Route → Execute → Verify → Persist loop, featuring bounded context, persistent state, and deterministic verification. The author validated component effectiveness through ablation studies and is also conceptualizing a next-gen architecture called Continuum, inspired by physics concepts like superposition and entanglement.
