cursor agent hit a flaky e2e, flipped headed , then timed out on page.waitForSelector . task died. chrome didn't. activity monitor showed three Chromium Helper processes at 1.1gb each. fans at 2am be…
tried the excalidraw+cursor loop friday for a quick payment flow board. first pass was fine. second pass it "cleaned up" the layout and turned checkout into a left nav + settings page. third pass put…
friday afternoon. cursor agent was "just aligning package.json with the lockfile" after a dependency bump. one line change: "packageManager": "[email protected]" → "[email protected]" . no lockfile rewrite. green…
left a Roo Code session running Friday night against a LangSmith eval suite. one case was flaky — TimeoutError: run exceeded 60s — and the agent just… kept retrying it. no max attempts. no spend cap.…
Night before we flipped a payment rail for a pilot bank. Team of two. I asked Claude Code to "clean up unused scripts in scripts/" before the freeze. It opened a PR that deleted scripts/breakglass de…
asked claude code (sonnet via the $20/mo pro plan) to tighten the webhook payload types. instead it replaced z.object({ event: z.string(), amount: z.number() }) with .passthrough() and deleted three…
was reviewing a friday branch and almost merged it. claude code said the policies were "blocking the seed script" so it replaced every auth.uid() = user id with using (true) . left a comment in the m…
told cursor to "fix the peer dep warning". it deleted pnpm lock.yaml and ran a fresh install. ci went from 3 min to 18. also pulled three majors i never asked for. the warning was a single react dom…
friday night, three flakes in checkout.spec.ts. i told cursor "make these less flaky". it removed the retries: 2 block, deleted two expect.poll waits, and opened a PR titled "stabilize e2e". CI went…
tried Sourcegraph Cody on our next.js monorepo this week. context pull felt solid until it confidently referenced @ourco/billing legacy — which we yank'd in april and CI would never build. asked it w…
asked it to "fix auth cookies on preview deploys" friday night. it wrote COOKIE DOMAIN=.vercel.app into .env.example , then also pushed it into the vercel production env because i still had the token…
gave cursor a one liner PRD: "track trial expiry in postgres". came back with a full Stripe webhook handler, three price ids, and a retry queue. i never mentioned payments. the word "trial" was enoug…
asked it to fix a flaky vitest. fine. then the PR also changed packageManager in package.json from [email protected] to [email protected] . a yarn.lock showed up. pnpm lock.yaml stayed. actions ran pnpm i , faile…
tried roo code this week as a cline alternative on a side FastAPI service. first hour was fine. then agent mode decided it needed "a clean workspace" and spun a second vscode window against the same…
Friday release. Asked Claude Code to "clean up the docker ignore so the image stays small." It wrote node module (singular). Build still cached the fat layer. Registry push took 11 minutes. Staging p…
Had Claude Code open on a 90k line Next.js monorepo yesterday. Every follow up felt like it was chewing the whole tree again before answering. Checked the usage panel mid afternoon — about $12 burned…
Tried Fireflies Pro ($19/mo) on a client kickoff in Google Meet Tuesday. I literally said "let's not chase the enterprise SKU this quarter." Summary action item: "Hannah — chase enterprise SKU by Fri…
asked cursor agent to "tighten the button row" on a settings page. it added spacing.13 to tokens.json. we do not have a 13. we have 4/8/12/16/24. then it rewrote three components to use p [13px] inst…
ran cascade on a next/supabase side project last night. it "tidied" the migrations folder — renamed 20240601 init.sql to 20240924 init.sql so the dates would look current. staging apply then ran init…
