List available Codex models. Pass nextCursor as cursor for another page.

Start a live Codex agent and return its threadId immediately after acceptance. Codex runs with full filesystem/network access and no approval prompts. Supply an absolute working directory and the complete task context; model is optional.

Send direction to a running Codex turn, or start another turn in the same thread if it is idle. A race with turn completion can return an error: inspect status before retrying.

Request interruption of a running Codex turn. The interrupted event confirms completion; this does not undo changes already made.

Attach a saved Codex thread after reconnecting. Use codex_message to continue its work.

Answer a Codex question using its requestId and all question IDs. Ask the user when the answer requires their preference; otherwise answer from the task context.

Read session state, pending questions and the latest answer. Omit threadId to list sessions. Does not wait for completion.

Read the bounded event journal after a sequence number. gap means older events were evicted. Use to recover results if channel delivery is unavailable; do not busy-poll.
