Codex app: Allow developer instructions per project, not as a whole #10509
Description
What variant of Codex are you using?
App
What feature would you like to see?
Right now we can only add instructions for customization / personalization for the entire app - please allow customizations (custom developer prompt) per project. When using the CLI, I utilize custom global prompts / roles (as developer instructions) separately from the AGENTS.md per project. This allows me to use a universal Swift Developer role for certain projects without repeating myself in each AGENTS.md
