  "account": "When Claude Code nears its five-hour time limit during a task, there are three options: wait for a reset, purchase additional API tokens, or transfer the task to another agent. The challenge isn't switching applications; it's the process of transitioning information between them. The issue arises because neither model retains knowledge of the other's activities. When one model gets stuck on a bug, the other might solve it in one go, but the new side still starts from scratch, requiring you to re-explain the project, current situation, and any issues. Simply copying and pasting the chat transcript is impractical, as the output can be extensive. To address this, I developed ccx, an open-source tool (MIT license) that runs on macOS and synchronizes Claude Code and Codex seamlessly. When Claude hits its limit, clicking the swap icon in the menu bar and selecting the project and session, allows Codex to take over with all the context retained. Similarly, if Codex runs out, returning to the Claude conversation and prompting it to \"continue\" allows it to pick up where it left off. All messages, responses, tool calls, output, task lists, Git status, and images are transmitted locally as context, not as separate chat bubbles. The tool maintains a record of the session files and thread information on the user's Mac, ensuring a smooth handoff without needing to re-explain anything.",
  "summary": "When Claude Code hits its 5-hour limit mid-task, you can wait for the reset, pay for API tokens, or move the task to another agent. I use both Claude Code and Codex, so the third option is the obvious one. The hard part isn't switching apps. It's the handoff: the other agent knows nothing about the task. The problem with switching I switch for two reasons: One side runs out. Claude Code has a…",
