Every dashboard prompt I tried gave me the identical gray-card-with-a-number-and-a-tiny-line-chart layout, and a table that was just a styled div with none of the behavior that makes a table useful. I

Prompt for React CRUD with optimistic updates and rollback that doesn't corrupt the cache
Systems guy dabbling in web here. Optimistic UI kept biting me: the happy path looked instant, but a failed delete left a ghost row, or two rapid edits raced and the cache ended up in a state that mat

One-shot prompt for a Rust + wasm image filter module wired into a web app cleanly
I wanted a real Rust-to-WASM module doing per-pixel work off the main thread, not a toy that ships 4MB of glue and blocks the UI on load. Most prompts gave me code that assumed a specific bundler and

Prompt for a typed third-party API client with real retry and error handling, not fetch soup
Every "integrate the Stripe/Notion/whatever API" answer I got was a bare fetch with no timeout, no retry, and a catch (e) { console.log(e) } that swallowed everything. Then it fell over the first time

Prompting a multi-step onboarding flow that people actually finish (not a 9-field wall)
Growth eng here. Our old signup was a single screen with nine fields and a 38% completion rate. I wanted AI to help me design a progressive flow, but the naive prompt just gave me the same nine fields

How I get GPT to scaffold a whole repo (folder tree contract) instead of a single file dump
0-to-1 is my whole thing, so I want the model to lay down a real repo I can take the wheel on, not one 600-line file I have to explode by hand. What finally worked was treating the folder tree as a si

Prompt for a PWA that works offline first try, without a service worker that caches stale forever
I build mobile web that should feel native, and the classic failure is a service worker that caches so aggressively users get a stale app for days and can't figure out why the update never lands. My p

How I prompt for an accessible signup + first-run flow that passes an audit by default
We failed an accessibility audit on our signup once: unlabeled inputs, an error summary that never got announced, focus that jumped to the top of the page after validation. Retrofitting a11y is misera
