Codex Knowledge Fabric — AGENTS.md overview

Codex CLI's knowledge fabric is centered on AGENTS.md files. At session bootstrap, Codex reads AGENTS.md from the project root and injects its contents as long-term project memory. This provides persistent instructions, conventions, and project-specific context across sessions. The knowledge scope is project-only — Codex does not have user-level or enterprise-level knowledge files. Codex runs in a sandboxed environment, so knowledge retrieval is limited to files within the sandbox boundary.

notes

Codex's knowledge fabric is minimal compared to Claude Code or Cursor. AGENTS.md is the sole persistent knowledge file. There is no auto-memory extraction, no user-level knowledge, and no vector-based retrieval. Knowledge is injected at session start and not updated mid-session.
