API Docs Generation with Codex: SKILL.md Template
A production playbook for API docs generation in cross-industry operations using Codex: skill.md template, 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
Put the operating procedure in SKILL.md, keep examples beside the skill, attach OpenAPI specs, examples, SDK snippets, and changelogs per run, and let Argo turn the folder into a repeatable Codex execution.
Tradeoffs and failure modes
A skill folder is less flexible than an open chat, but it gives the product a versioned workflow that can be tested and rolled back. 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.
SKILL.md starter
# SKILL.md
You run API docs generation using Codex.
Read only /skill/.argo/inputs.
Write artifacts to /skill/output/artifacts.
Return argo.result.v1 with body.type = "api_docs_generation".
Run this on Argo
