Resume Threads

Prerequisites: - A previously created thread ID

What you'll learn: - How to continue an existing session - How to structure resumable workflows

Basic Resume

from codex_sdk import Codex

saved_id = "thread_abc123"
thread = Codex().resume_thread(saved_id)
result = thread.run("Continue from where we left off")
print(result.final_response)

Persisting Thread IDs

Recommended: - Save thread.id after each successful turn - Store alongside your task/job metadata

Safety Pattern

if thread.id is not None:
    save_id(thread.id)

Failure Modes

• Using stale IDs that no longer map to valid underlying session state
• Creating a new thread by mistake instead of resuming
