Agents write most of the code now. Ultracite is the linter and formatter for agentic development, a zero-config preset for Oxlint, Biome, and ESLint that keeps agent-written code consistent and type-safe. Ultracite checks every edit agents make against hundreds of strict rules in under half a second, so what reaches review is consistent, type-safe code instead of slop. Used by engineering teams at OpenAI, Vercel, Mintlify, and thousands of open source projects: ultracite.ai
If my project already has custom ESLint rules, does Ultracite work with them, or does the preset take over??
Congrats Hayden on shipping Ultracite v8, and thanks fmerian for the hunt. Putting every agent's rules in one AGENTS.md instead of a file per tool removes a lot of quiet drift. When ultracite fix --claude hands over what autofix can't settle, what stops the agent from clearing a diagnostic with an ignore comment instead of fixing the code? Is that something the anti-slop preset catches?
