System prompt for a dark-mode-first design token set that isn't just inverted grays
Every "add dark mode" prompt gives me pure black backgrounds, fff text, and one flat gray for everything. It looks like a terminal, not a product, and the contrast is actually too harsh at night. I tu

Output contract that makes the model write code future-me won't hate
My gripe isn't that AI code is wrong, it's that it is unmaintainable: 80-line functions, clever one-liners, no seams for testing, magic numbers everywhere. It passes review by looking confident. I sto

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

Low-poly procedural terrain in three.js that regenerates from a seed with a flat-shaded look
I was chasing that faceted low-poly island aesthetic. My first attempts used a smooth normal PlaneGeometry so it looked like melted plastic, not crisp facets. Also the terrain wasn't reproducible so I

Prompt that writes the migration AND a reversible down-migration, not just the ALTER
Models are great at spitting out ALTER TABLE statements and terrible at remembering that migrations run on live data with existing rows. I got burned adding a NOT NULL column with no default to a tabl

Prompt for a log-tailing CLI that parses, filters, and summarizes without loading the whole file
I wanted a small tool to slice gigabyte-sized JSON-lines logs by level and time range and print a summary, but the first version the model gave me did open(f).read() and json.loads on the whole thing,

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

Real-time metrics dashboard with sparkline gauges over a websocket feed
I was building a live ops board that streams a few dozen metrics over a websocket, each shown as a number plus a rolling sparkline. The naive build re-rendered the entire React tree on every message a

System prompt to give a chatbot a consistent personality without it getting cutesy
Giving a bot "personality" usually means it starts every message with a quip and an emoji and becomes exhausting by the third turn. I wanted a distinct, dry voice that stays out of the way. The approa

Planning-loop prompt that makes an agent decompose before it touches any tools
Our agents were too eager. Given a task they'd immediately start editing files, then discover halfway through that the approach was wrong and thrash. Latency and token cost ballooned from all the back

How I prompt a platformer jump that feels like Celeste, not like a brick
The single biggest reason AI platformers feel bad is the jump. You get gravity, you get a jump impulse, and it's stiff and unforgiving. The magic is all the invisible assists that pro platformers ship

One-shot prompt that scaffolds a Next.js 14 App Router SaaS that actually compiles
I kept asking for "a Next.js SaaS starter" and getting a pile of files that referenced components that didn't exist, mixed the pages and app routers, and threw 40 type errors on first pnpm build. The

Debugging an intermittent asyncio race the model kept papering over
Had a flaky test that failed maybe 1 in 30 runs. Every model I tried "fixed" it by adding an await asyncio.sleep(0.1) somewhere, which is not a fix, it is a bribe. The real bug was two coroutines muta

One-shot prompt that builds a complete SaaS landing page with pricing table

One-shot three.js hyperspace starfield that stays 60fps on a laptop trackpad
I wanted the classic warp-speed starfield but every naive attempt spawned 20k separate Mesh objects and my fans took off. The trick was forcing the model to reach for InstancedMesh (or a single Points
