What are AI architecture prompts?

They're pre-written instructions that guide AI models like ChatGPT to produce architecture-style output with consistent structure, tone and quality.

Which AI model works best for architecture?

ChatGPT is the most reliable starting point, but Claude and Gemini also produce excellent results depending on your style preferences.

Can I customize these prompts?

Yes. Each prompt uses placeholders you can swap for your own topic, audience and tone. Treat them as a strong starting point, not a final answer.

Are these prompts free?

Yes — every prompt in the Coding library is free to copy and use. You only need an account with the AI model itself.

Editorial

The architecture prompt library, explained

This is the Architecture hub, part of our broader Coding collection. You'll find 5 architecture prompts written specifically for this workflow — each one structured to give the AI the role, audience, format and constraints it needs to produce output you can use immediately.

These prompts are built for software engineers, ML engineers and indie devs who want code, tests and architecture suggestions they can ship. They work across the major AI models — ChatGPT, Claude, Gemini and the leading image and video generators — and they hold up whether you're prompting in a chat window, an editor extension or a workflow tool. Pull these in during scoping, scaffolding, refactors and code reviews — anywhere a teammate would help.

Why these prompts work: each one starts with a clear role, names the audience or scene, defines the output format and adds 2–3 hard constraints. That structure is what separates a vague AI answer from a usable one. The library is curated so you don't have to test 30 versions of the same prompt to find the one that actually performs — that work is already done.

Expect production-style code, types, edge-case handling and at least a smoke test — written in the style you specify. You'll occasionally want to regenerate or refine, especially the first time you use a prompt with your own context. Treat each prompt as a starting structure: the variables and constraints stay, the topic and tone become yours.

Read each prompt before you copy it. Swap the placeholders for your real audience, product and constraints, and add one or two engineering-specific details from your own brief. The prompts here are designed to be edited — the more context you bring, the stronger the output.

If this is your first time using AI for architecture, start with the featured prompt below and adapt it to your context. Then explore the related use cases for adjacent workflows that often pair well with this one.

Next.js Gallery: Intercepting Routes & Parallel Modals

Why it works · It defines the runtime, behaviour and edge cases, then asks for tests — turning the AI from a code generator into a reliable engineering pair.

Best use case

Best for architecture workflows where this guide helps next.js developers implement a photo gallery featuring advanced modal behavior using parallel and intercepting routes. it outlines how to display images as modals from a gallery view and as dedicated pages from a direct url, covering file structure, data handling, and caching.

Expected output

Working code in the runtime you specified, with edge cases handled and a small test you can run immediately.

Prompt Writing Guide

How to write better Architecture prompts

Six habits that consistently produce stronger AI output. Apply them to any prompt on this page.

1
State the runtime and stack
Language, version, framework, target platform. "Node 20 on Cloudflare Workers" produces very different code than "any JavaScript".
2
Write the requirements first
Functional behaviour, inputs, outputs, error handling. The AI is excellent at following a spec and mediocre at guessing intent.
3
List the edge cases
Empty arrays, null, network failures, race conditions, oversize payloads. Naming them up front prevents the "happy path only" trap.
4
Ask for tests
Request a small test suite alongside the implementation. Tests force the model to reason about boundaries — and you get verification for free.
5
Pin code style
TypeScript strict, no `any`, named exports, early returns. Pin style and you'll spend zero time on lint cleanup.
6
Demand explanations on tricky parts
Ask the model to comment any non-obvious step. Comments expose flawed reasoning before you ship the code.

Best Practices

Architecture best practices

Apply these in every prompt on this page. Small habits, outsized improvements in output quality.

Pin the runtime and version

Language + framework + version. Skip and you'll get half-deprecated APIs.

Write the spec first

Inputs, outputs, errors, edge cases. The AI is a great spec follower.

Ask for tests alongside code

Tests catch flawed reasoning before you ship.

Forbid `any` in TypeScript

One rule removes 80% of weak AI-generated TS code.

Avoid These

Common Architecture prompt mistakes

The same handful of mistakes are responsible for most weak AI output. Catch them before you hit send.

Missing the runtime
Different runtimes have different APIs. Without it, the AI guesses — usually wrongly.
Glossing over edge cases
If the prompt only describes the happy path, the code will only handle the happy path.
Asking for "clean code"
"Clean" is subjective. Specify naming, style and lint rules instead.
Skipping tests
Without tests you have no way to verify the AI's reasoning. Always ask for at least a smoke test.
Pasting too much code
Dump only the relevant functions and types. Long context dilutes attention.

Pro Tips

Advanced prompt patterns

Side-by-side rewrites that show what separates a weak prompt from a great one.

Instead of

“Write a function to debounce.”

Use

“Write a TypeScript `debounce<T>` higher-order function targeting Node 20. Cancel in-flight calls, return a `.cancel()` method, preserve `this`, type the return as `(...args: Parameters<T>) => void`. Include 4 Vitest tests covering rapid calls, cancel, late call, and `this` binding.”

Why it works: Stack, behaviour, types and tests are all defined.

Instead of

“Make this API.”

Use

“Implement a REST endpoint POST /api/invoices in Hono on Cloudflare Workers. Validate body with Zod. Return 400 on invalid input, 409 on duplicate, 201 with the new invoice on success. Include a small handler test and a sample curl.”

Why it works: Framework, runtime, errors and verification are pinned.

Instead of

“Fix this bug.”

Use

“Here's the error: `TypeError: cannot read 'map' of undefined`. The function receives `items` from the API. Add a guard, log a warning when it's missing, and update the test to cover the empty case. Don't change the public API.”

Why it works: Symptom, expected fix and scope are explicit.

Instead of

“Optimise this query.”

Use

“This Postgres query takes 1.4s on a 12M-row `events` table. The filter is `user_id = ? AND created_at > ?`. Propose 2 index strategies, explain the trade-offs, and rewrite the query if helpful.”

Why it works: Volume, filter and trade-off framing produce useful answers.

Instead of

“Refactor this code.”

Use

“Refactor this React component to extract the data fetching into a TanStack Query hook. Keep the rendering identical. Add types, no `any`, and update tests if they reference the old API.”

Why it works: Boundary and constraints prevent over-refactoring.
