Where the workflow shifted
The Codex AGENTS.md guide turns project conventions, test commands, engineering rules, and done criteria into context the agent can read.
Document repo layout, setup, test commands, pull-request expectations, prohibited actions, and the definition of done.
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
- Add an AGENTS.md covering setup, tests, linting, PR format, risky commands, and acceptance criteria
- 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
Without repository instructions, agents infer team norms from code and often miss tests or review boundaries. Keep the original source open so the announcement, the evidence, and this site's interpretation stay separate.
