Prompt: Write Technical Documentation

Technical documentation is the task that gets pushed to "later" on every sprint. The code ships. The docs do not. Six months later, nobody remembers how anything works and the original developer left.

This prompt generates technical docs that are clear and complete. Use it to prompt write technical documentation ai drafts that your team can verify and publish fast.

The Prompt

Write technical documentation for the following:

WHAT: [System, API, feature, process, or tool to document]
AUDIENCE: [e.g., "Backend developers integrating our API" or "Non-technical team members using the admin panel"]
TECHNICAL LEVEL: [Beginner / Intermediate / Advanced]
CODE LANGUAGE: [If applicable]
EXISTING DOCS: [Paste any existing documentation to maintain consistency]

Structure the documentation as:

1. OVERVIEW
   - What this is and what it does (3 sentences max)
   - When and why you would use it
   - Prerequisites (what you need before starting)

2. QUICK START
   - The fastest path to a working example
   - Numbered steps with code snippets where applicable
   - Expected output at each step

3. DETAILED REFERENCE
   - For APIs: every endpoint with method, URL, parameters, request/response examples, and error codes
   - For features: every option with description, default value, and usage example
   - For processes: every step with detailed explanation and edge cases

4. COMMON PATTERNS
   - 3-5 real-world usage examples that go beyond the basics
   - Each pattern: scenario description, code/steps, expected result

5. TROUBLESHOOTING
   - 5-10 common errors with causes and fixes
   - Format: "If you see [error], it means [cause]. Fix: [solution]"

6. CHANGELOG
   - Recent changes with dates (if known)

Rules:
- Every code example must be complete enough to run (no "..." placeholders)
- Every parameter must include its data type and whether it is required or optional
- Write for the specified audience. Do not explain basic concepts to advanced users or use jargon with beginners.
- Include copy-pasteable code blocks
- If something could go wrong at a step, warn about it before the step, not after

Why Quick Start Comes First

Developers want to see it work before they read the reference docs. If the quick start takes more than 5 minutes, it is too long. Get them to "hello world" fast, then let them explore the details.

Maintaining Docs Over Time

The hardest part is keeping docs current. Pair this prompt with your release process: every time code ships, run the documentation prompt with the changelog and updated specifications. The AI updates the affected sections. A developer reviews for accuracy.

Stale docs are worse than no docs because they build false confidence. If you cannot keep them current, label them with a last-verified date so readers know what they are working with.
