Prompt for a Next.js email + OAuth auth flow with sessions that survive a refresh
Auth is where my "ship it" energy usually crashes. I asked for login and got a flow that stored a JWT in localStorage, had no CSRF thought, and logged the user out on every hard refresh because the se

Endless runner prompt with procedural obstacles that stay fair as speed ramps

Prompt to turn a rambling meeting transcript into decisions, owners, and open questions

Touch bottom-sheet micro-interaction that feels native without a JS animation lib

Guardrail prompt so my coding agent stops inventing files it never read

Support-agent system prompt with escalation rules that actually hand off cleanly
I build customer support bots and the recurring failure is the bot pretending it can do things it can't (issue refunds, change a subscription) and then dead-ending the user. Or the opposite: it escala

Prompt for React CRUD with optimistic updates and rollback that doesn't corrupt the cache

How do you prompt GPT for an editorial, type-driven landing hero (think magazine, not startup)?
I come from print. I want landing heroes that feel like the opening spread of a good magazine: a strong typographic idea, real hierarchy, confident negative space. What I keep getting from GPT is a co
