API Docs Generation with Codex: API Runtime Pattern
A production playbook for API docs generation in cross-industry operations using Codex: api runtime pattern, run-scoped inputs, logs, typed results, and artifacts.
Audience: Developer experience teams
The problem
Developer experience teams need API docs generation to run repeatedly against OpenAPI specs, examples, SDK snippets, and changelogs. In cross-industry operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Package the API docs generation instructions as a skill, send OpenAPI specs, examples, SDK snippets, and changelogs as run-scoped inputs, execute with Codex, poll terminal status, and consume argo.result.v1 instead of parsing a transcript.
Tradeoffs and failure modes
The API boundary forces the workflow to define inputs, terminal states, and result shape before customers depend on it. For API docs generation, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
