I ported Impeccable’s engine to Rust. The design hooks that catch AI slop after each edit now run in ~10ms. • ~4× faster hooks, ~2× faster file scans in our benchmarks • no Node setup to run the skill • the same rule engine across the CLI, browser extension and live mode And GPT Image 2.5 landed today. It’s already in Impeccable 4.3, with faster comps and native transparent assets. Generated illustrations can now sit directly on your own backgrounds. White petals stay white. Gaps between leaves stay transparent. Also shipped since my last update: stricter comp-to-code fidelity checks, per-app design rules in monorepos, DeepSeek Harness support, and a VS Code Marketplace install for Copilot. Impeccable 4.3 is out now. If you haven’t updated in a while, this is a good one.
