Where the workflow shifted
OpenAI Codex describes code writing, codebase understanding, review, and project adaptation; buyers need to know how those capabilities become a completed task.
Move first-screen copy from model capability to delivery result: input, files touched, checks run, and evidence returned.
Tool names are not outcomes
The signal matters when it changes how a team ships, reviews, or recovers work, not when it only names another tool.
Check permissions and failure
- Write one real development task as an issue with acceptance criteria, allowed files, test commands, and pull-request evidence
- Keep the test narrow: one low-risk task or tool entry before connecting permissions, logs, failure handling, and human takeover to production
What still needs proof
If the page only describes model capability, readers still cannot place the agent inside their team workflow. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
