For information about AGENTS.md, see [this documentation](https://developers.openai.com/codex/guides/agents-md).

## Hierarchical agents message

When the `child_agents_md` feature flag is enabled (via `[features]` in `config.toml`), Codex appends additional guidance about AGENTS.md scope and precedence to the user instructions message and emits that message even when no AGENTS.md is present.
Replaced user documentation with links to developers docs site (#8662) This eliminates redundant user documentation and allows us to focus our documentation investments. I left tombstone files for most of the existing ".md" docs files to avoid broken links. These now contain brief links to the developers docs site. 2026-01-02 13:01:53 -07:00			`# AGENTS.md`
