What issue are you seeing?

When working in a shared repository, AGENTS.md is committed to git and shared across the team. Several times I have needed an ammendment to the AGENTS.md file that is repo local and personel to me. For example: "Please reference my local notes in ~/project1-notes/". This shouldn't be shared with the team/project. Using a global override in ~/.codex would apply this to all my projects, and editing the repo AGENTS.md would share it with my team.
