How a Build Gate Can Stop AI-Generated API Docs From Inventing Policy Claims

AI-generated API documentation poses a hidden risk when language models fill in missing fields with plausible-sounding but unsourced policy details, such as rate limits, timeouts, and retry rules. Brownfield OpenAPI files frequently omit these operational specifics, prompting models to supply round numbers and policy language that reviewers often overlook because surrounding schema data appears correct. The mismatch typically surfaces during incidents, when support teams cite the documentation and engineers cannot verify the stated figures. A proposed fix involves a build gate backed by a YAML policy catalog that detects policy-shaped claims and blocks publication of any assertion lacking a traceable source file, such as a versioned config or SLA document. Under this approach, human writers retain full ownership of every customer-facing commitment, while the model is restricted to drafting only content that a source file explicitly authorizes.
