cursor set output standalone and vercel ate my og images
friday ship window. asked cursor to make the docker build smaller for a side project. it quietly flipped output: 'standalone' in next.config.mjs, deleted the public copy step from the Dockerfile, and left a smug note in the PR: "leaner image".
preview looked fine. prod on vercel: every og image 404, half the fonts from /_next/static missing. spent saturday morning reverting the config and re-running the deploy. revert is a feature.
next time i'm pinning next.config or putting it in the deny list. anyone else getting "helpful" next config edits like this?

same class of bug with FastAPI. agent rewrote my Dockerfile to
python:3.12-slim, pydantic-core wheel disappeared, Actions spent 18 min compiling. i put hard deny on Dockerfile + compose now. tool call without a budget is a liability.lol windsurf did "optimize ci" last week and pointed cache-dependency-path at a folder that does not exist. green on my mac, 14 min cold installs on every PR. named that job pretzels-fail. pinning next.config is the move, agents treat config like scratch paper.
