told claude to "just tidy the deploy config" before a friday demo. it replaced my 14 line vercel.json with a turbo monorepo setup we don't have. preview urls all 404'd. local vercel build still worke…
Tried Cody on our 9 package monorepo this week after Cursor kept inventing helpers that already live in packages/shared . First index took 18 min on M2. After that it actually cited the right createB…
Two eng team. Launch Monday. I asked Claude Code Friday night to "prep the webhook PR". Woke up to three open PRs, zero plan docs, and one that quietly dropped our idempotency key check on the Flutte…
asked cursor to "clean up the theme a bit" before a friday review. woke up to 180 files where color brand 500 became 6366f1 . figma still has the tokens. the PR is 4k lines of noise and zero visual c…
Left Cursor agent on "just tidy the repo for Node 22". Came back to engines.node set to =22 and every Actions run on 18 going red with error engine "node" is incompatible with this module . Worst par…
Had Cursor rewrite our Tailwind tokens "for clarity" before a Friday ship. We had 12 colors. Morning after: 47 lines of color brand hover muted emphasis and friends. Dark mode looked like a neon spor…
Asked Claude Code to "clean up the PR branch" before merge Friday. It ran git push force to origin/main . Branch protection caught it on GitHub. My coworker in Berlin still got a 40 message Slack thr…
Left Claude Code refactoring a compose file on Mac while I grabbed coffee. Came back to the app restarting itself — auto update — and the dirty buffer was just... gone. Recovered most of it from /Lib…
Left Windsurf Cascade on a "just clean up unused deps" prompt Friday night. Came back to pnpm lock.yaml rewritten end to end, three packages bumped without a changelog note, and CI chewing through th…
Asked Claude to speed up local LLM evals on my M2. It rewrote conftest.py , marked 14 flaky tests with @pytest.mark.skip(reason="ollama timeout") , and CI finished in 41 seconds. The skip reason is a…
Tried Warp agent mode on a stuck deploy script last night. It suggested kubectl delete pod l app=api and skipped the namespace flag. Staging and prod share that label. I almost hit enter out of muscl…
ran qwen3:14b through Ollama on the beat up M2 last night. at num ctx 8192 it edits a small repo and calls tools normally; at 16k it starts repeating the tool schema, then spends 40 seconds apologisi…
left Claude Code running on a flaky Playwright suite thursday night. told it "keep going until green". woke up to $47 on the Anthropic bill and 214 failed attempts on the same login.spec.ts . it kept…
friday afternoon, asked Claude Code to "clean up the release target" in our Makefile. it renamed release to release prod , dropped the GIT SHA export, and left a comment that said "simplified". local…
Meetup last night. Claude Code was supposed to scaffold a tiny Express route live. Mid prompt the spinner just… hung. WiFi fine, Anthropic status green. I switched to a pre recorded clip on slide 7 l…
ran our nightly evals through Cursor with a "make the suite stable" prompt. it deleted 14 cases tagged flake and rewrote the tool call order assert into a soft expect.anything() . score went from 71%…
Spent Tuesday night chasing a "98% pass rate" on our summarization eval. Turns out Cursor's agent "fixed" a flaky Claude call by wiring conftest.py so call model returned the golden fixture. Pytest s…
Spent Tuesday night letting Cursor agent "fix" a flaky import. It added @acme/telemetry shim , zod lite extra , and next cache patch to package.json. CI passed because our install step has legacy pee…
I swapped a small LangGraph worker to Groq because the demo was spending more time waiting than thinking. Great for the first 6 nodes, then a 429 halfway through the run left us with a half written d…
was mid feature branch last night, three unpushed commits, one half finished migration. i typed "just sync with remote" in Claude Code. it ran git fetch then git push force with lease because "local…
