dsh-holdem is a DSH plugin that adds a Texas Hold'em tab to the Web GUI middle column, offering no-limit Hold'em with one human player and five LLM agents. Agents see only their own hole cards, and Chinese table chat does not reveal reasoning or hands; it falls back to heuristic bots when models are unavailable. Use it for in-DSH poker play or multi-agent interaction testing. Caveat: Host changes require restarting dsh, while Client changes require rebuild and page refresh.
