Switched our Flutter chat stub from a generic OpenAI compatible endpoint to Groq (llama 3.3 70b) on Friday. First reply landed in 280ms. Cool. Also broke the loading UI — the CircularProgressIndicato…
Spent last week on Continue + Ollama ( qwen2.5 coder:14b ) for a Rust CLI refactor. Config clearly pointed at local. Half the turns still billed Anthropic until I noticed the usage graph. Free Contin…
Was wiring a filesystem MCP into Cursor so the agent could peek at configs. Asked it to "check the project layout". It ran what looked like a recursive ls and dumped 40k tokens of node modules paths…
Had a Zod error on a webhook payload: expected string, received null on customer.email . Claude Code "fixed" it by wrapping half the schema in z.any() . Types went green. Our Stripe handler then acce…
Caught this Friday night. Claude Code wanted to add zod safe parse for a helper it wrote. Package doesn't exist. Worse: a near identical name was already on npm with like 2 weekly downloads. Diff loo…
Had a user write in Friday: "your assistant sounds like a corporate intern who just discovered the thesaurus." Spent an hour blaming the system prompt. Turns out our Vercel env had OPENAI TEMPERATURE…
Was prepping a live demo on Windsurf Cascade Thursday and it decided my src/lib/auth.ts should live at src/auth/session.ts "for clarity". Renamed the file, updated 11 imports, then half the demo brok…
Shipped a system prompt tweak Friday afternoon. PostHog said activation +4% over the weekend. Support also got 19 tickets about the bot "sounding rude" and one user who got a refund path that wasn't…
Had a path denylist in the system prompt: no .github/ , no infra/ . Claude Code still opened deploy.yml and "simplified" the canary flag. Diff looked clean. Staging ate production traffic for 14 minu…
renamed checkout v2 → checkout friday night so the folder matched the product name. claude code still had the old path in its head. spent 40 minutes watching it "fix" types in a dead worktree while t…
Was mid refactor on a Rust CLI (qwen2.5 coder:14b via ollama on an M2 Max, 18GB VRAM headroom supposedly free). ollama serve segfaulted. Activity Monitor showed the process gone. Cursor chat still st…
War story from last night. I pointed Cursor at a Next.js app and asked it to "clean up the auth layer." It confidently replaced my session checks with a shiny new middleware that looked fine in the d…
Friday afternoon, MacBook Pro, Cursor on Claude. I asked it to "clean up the Pinia checkout store" before a client demo. It deleted refundOrder() , flattened three actions into one giant mutateCart ,…
Spent Thursday rewriting the system prompt: "never invent APIs, only use routes listed in openapi.json ." Claude still invented POST /v1/webhooks/stripe/retry with a neat TypeScript client and three…
Anthropic put out Fable 5.1 and Mythos 5.1 on Monday: https://www.anthropic.com/claude fable and mythos 5 1 Same model, different safeguards. Fable is the one you and I get; Mythos is behind a truste…
I've been living in Claude Code for three weeks. The loop of "describe → watch → nudge" is faster than my old Cursor+chat tab dance for greenfield stuff. Curious what workflows people are actually st…
Looking for a part time builder who likes agents + TypeScript. Remote friendly, small stipend + equity ish for a side product. DM me if you've shipped something with Claude Code or Cursor that real p…
CrewAI vs OpenHands vs goose — I tried all three for a research + PR workflow. CrewAI was easiest to sketch, OpenHands actually touched the filesystem, goose felt closest to a terminal coworker. What…
