Built-ins specific to Gemini

Beyond the universal slash commands (/help, /clear, /compact), Gemini ships a few worth memorizing. /tools lists active tools (built-ins + MCP servers). /memory manages persistent memory across sessions. /chat save NAME + /chat resume NAME for named long-lived conversations. /stats for session metrics.

Code

/chat list                      # see saved chats

Exercise

Use /memory add to add three persistent facts about how you want Gemini to behave. Use /chat save to snapshot a real long-running task. Resume the chat tomorrow and verify both memories and the snapshot survived.
