Technical design doc
Explain how a system or feature will be built—architecture, data model, APIs and alternatives—and assess performance, risks, rollout and rollback.
Prompt
Write a technical design doc for moving an order system to asynchronous processing with a message queue. Purpose: support the design review and guide implementation. Requirements: state the background, goals and non-goals, current state and constraints, give the architecture and core flows, detail module responsibilities, data model and interfaces, compare at least one alternative, cover capacity estimates, fault tolerance, security and observability, explain migration, phased rollout and rollback, and list risks, open questions and the work breakdown. Explain the why before the how, in a crisp, professional tone.

FAQ
What kind of file do I get?
A complete, downloadable document (Word or PDF) — not just a block of text in the chat.
Do I need to prepare anything?
No — you can send it right away and Ofox Chat writes a first version from the template. Add your background, data or existing documents (paste them in, or upload PDFs, Word files and more) and the result fits your situation much better.
Can I edit the prompt?
Yes. The prompt goes into the Ofox Chat input box — swap in your own topic, add requirements or drop what you don’t need before sending.
Can I copy and use the prompt directly?
Yes. Tap “Copy” on the prompt card to get the plain text — it works in other AI writing tools too.
