What issue are you seeing?
Based on my own usage, when I use plan mode—i.e., running the /collab command and selecting “plan”—Codex skips reading the AGENT.md file.
Evidence: In AGENT.md, I instructed it to output the sentence “AGENT.md file has been read” after each reading, and I explicitly required all responses to be in Chinese. Neither of these rules is enforced in plan mode.
What steps can reproduce the bug?
- edit ~/.codex/config.toml , add following
[features]
collab = true
collaboration_modes = true- running the
/collabcommand and selecting “plan"
What is the expected behavior?
