A Practical Guide for Claude Code, Codex, and Hermes Agent The /goal command (a.k.a. goal mode or persistent goals) is one of the most important 2026 advancements in autonomous AI agents. It turns one-shot prompts into fire-and-forget, judge-verified workflows. Instead of you babysitting the loop, you declare a durable objective with a verifiable end state.
