Claude Code's /goal interrupts for user judgment calls and gives up early on long tasks, while Codex runs unattended to token exhaustion—opposite of the intended paradigm.

Summary
Long-horizon agent tasks fail not from capability gaps but from model behavior: Claude Code breaks autonomy by asking for direction mid-task, forcing manual monitoring. Codex demonstrates that stubborn, delegation-averse execution actually scales better than orchestrated subagents.

Implementation verdict
Don't switch to Claude Code /goal yet for overnight/unattended tasks. Codex /goal is production-ready for long runs despite 400K context default. Claude Code 2.1.139 adds the feature but requires babysitting—use it for interactive, short-horizon work only. Anthropic's laziness regression (April 16 rollout) never fully recovered; the RL layer internalized the bias.
