Hi HN! A few friends and I built EarthToPixels, a project that turns real-world cities into explorable pixel-art maps. We fine-tuned an open-source Qwen image model and built a pipeline that takes aerial imagery, generates pixel-art tiles, and keeps neighboring generations visual

r/AI_Agents

I built a benchmark to test whether AI agents break architecture rules. It found none. (null result, with the harness and data)

The common claim: your CLAUDE.md / AGENTS.md is guidance, a lint rule is enforcement and AI coding agents drift from prose, so you need the deterministic rule. I wanted to measure that gap. I mined a real import-boundary rule from a near-census of 24,888 public TypeScript repos (
