Hermes-agent adds /undo command to revert conversation turns

The addition of a native undo command in a CLI agent tool is a massive quality of life improvement for anyone building complex agentic workflows. Most current interfaces force a hard reset or manual deletion when a multi-turn conversation veers off track, which kills momentum. By allowing users to back up N turns and prefill the last message, Hermes-agent acknowledges that prompt engineering is an iterative, messy process.

This feature specifically targets the friction in terminal-based and messaging-based interfaces where state management is usually rigid. It is a pragmatic move that prioritizes developer velocity over perfect state persistence. Operators should look for this level of granular control in other agent frameworks, as it significantly reduces the cost of experimentation during the refinement phase of agent development.
