How we AI-updated 1,138 Error-code Docs Pages

Twilio used an AI-assisted, human-reviewed workflow to update 1,138 API error-code documentation pages in about 12 weeks, addressing a catalog that had become inconsistent as it grew from roughly 2,692 to more than 3,200 codes. A deterministic script first scored pages for structure, content, and resource quality, routing only weak pages to an LLM pipeline that generated revisions, sanitized output, created Git patches, linted results, and opened pull requests. The process emphasized safeguards including prompts that allowed the model to make no change, strict limits on links and unsupported claims, code-snippet fingerprinting to reject any altered examples, and human technical review of every diff. Reviewers identified recurring AI failures such as meta-commentary, semantic changes to error explanations, formatting problems, and accidental code edits caused by post-processing scripts. Twilio reports that the approach reduced work that would have required an estimated 18,000 manual hours while establishing consistent documentation standards for future error codes, though it notes that automated evaluation, diff-only model outputs, and merge-status synchronization remain opportunities for improvement.
