Codex token budget guardrails

OpenAI's Codex changelog lists configurable rollout token budgets that can warn or abort agent turns when usage crosses a defined limit. Why it matters: Unattended agent loops need hard usage boundaries. Budget-aware turns make cost and runaway-task risk easier to control before a workflow is automated.

Try this: Set a conservative token budget for one low-risk Codex task, verify the warning or abort behavior, and record which steps consume the most budget.
