OpenAI Codex Team Verifies: Doc Completeness Dictates Agent Quality
sujingshen · x · 2026-07-03
The OpenAI Codex team established a nearly identical mechanism during their "zero lines of handwritten code" experiment: checking the execution plan into the repo as a feature list with progress logs, deploying a "document gardening" Agent to auto-scan outdated docs, and using the entire docs/ directory as the Agent's persistent knowledge base. Two top-tier teams independently reached the same conclusion: an Agent's quality ceiling depends not on how smart its prompt is, but on the completeness of its underlying documentation system.
