AI automation in API/SaaS documentation is a breakthrough for freelance technical writers, but generated code snippets require a critical validation step before they appear in your docs. You don’t need deep developer skills to verify that AI-produced code is syntactically correct and aligns with your API spec. Here’s a concise, actionable game plan.
Start with Linters and Formatters
The fastest way to catch syntax errors is to run a language-specific linter. For JavaScript, use ESLint with a basic configuration. Many online linters are available if you prefer not to install anything locally. For compiled languages like Java, a simple javac command on a stripped-down class will flag compilation issues immediately.
Integrate these tools into your workflow by running them locally or via a simple script. The goal is a rapid feedback loop: paste the AI snippet, run the check, and note any errors. Then return to your AI prompt (as covered in Chapter 5 of the e-book) with a correction request like: “Fix the syntax error in line X.”
Test Sandbox Execution
Paste each snippet into a relevant online sandbox. Replit, CodePen, or platform-specific sandboxes let you execute the code in a safe environment. Never use live production keys or data in these tests. Always use the platform’s provided test credentials and sandbox. This is a critical safety rule that protects both you and your clients.
Validate Against Your API Spec
Syntax is only half the battle. The snippet must actually work with the API it claims to support. Use a prompt for API conformance: combine your snippet and your OpenAPI specification in a single prompt. Ask the AI to verify that endpoint URLs, headers, parameters, and response handling match the spec. This catches mismatches early.
Actionable Checklist for Automated Checks
- For compiled languages (e.g., Java), use a simple
javac command on a stripped-down class to check compilation.
- Note any errors and return to your AI prompt with a correction request: “Fix the syntax error in line X.”
- Paste each snippet into a relevant online sandbox.
- Run a language-specific linter/formatter locally or via a simple script.
This checklist turns validation from a guessing game into a repeatable process. Even if you’re not a developer, each step is tool-driven and requires no coding expertise—just the discipline to run the checks.
Example: Spotting a Mismatch – A generated Python snippet might have correct syntax but reference a deprecated endpoint. Running the sandbox test against the platform’s sandbox environment will reveal an authentication error. That’s your cue to go back to the AI, adjust the endpoint, and retest. Every iteration removes uncertainty.
Automation doesn’t mean blind trust. By embedding these validation steps into your AI-assisted writing workflow, you deliver polished, reliable code examples that developers can copy and use immediately — building trust in your documentation and your brand as a technical writer.
