 Add persistent memory to the [**DeepSeek Harness**](https://github.com/deepseek-ai/deepseek-harness) with `@mem0/deepseek-plugin`. The plugin recalls relevant context before a model request, captures completed turns, and provides explicit Mem0 tools when the agent needs them.

-## Session handoff

-The plugin can hand off supported native session context into a new Codex task through the shared importer. Handoff requires Python 3.11+ and a locally installed, signed-in Codex CLI. See [session handoff](/integrations/session-handoff) for commands, transferred content, and recovery.
