dsh-more-message-actions

The DeepSeek Harness message list is read-only: you cannot edit a prompt, retry an unsatisfying answer, or delete a stray message the way you can on the DeepSeek web UI or in ChatGPT. dsh-more-message-actions plugs that gap by injecting five action buttons—Edit, Edit & Retry, Retry, Advanced Retry, and Delete—into every message row, restoring the familiar chat-management workflow inside DeepSeek Harness.

Every action is an in-place, single-point rewrite; no conversation forks are created. Deleting an AI reply removes that turn's chain-of-thought and tool calls together while preserving the corresponding user prompt, and deleting a user message leaves its AI reply intact. Advanced Retry lets you type an extra instruction, truncate the old answer, and regenerate with the original prompt plus your new requirement, making it easy to steer the model in a different direction without losing context. Under the hood, a Host half rewrites the persisted log and resets coordinator cursors while a Browser half injects the buttons and maps DOM keys to persistent IDs.

If you use DeepSeek Harness regularly for prompt iteration, code debugging, or long-form writing and find yourself copy-pasting and manually re-sending messages, this plugin turns that repetition into a single click. Keep in mind it operates on internal engine structures, is blocked while a turn is running, cannot safely replay turns that contain image attachments, and you should verify backup files before working on important sessions.
