LiveKit offers several thoughtful ways to handle selective context transfer, making sure your conversations stay relevant and efficient: • Truncating Context: You can use the

before_llm_cb

callback in

VoicePipelineAgent

to trim down the message history before it reaches the LLM. For instance, keeping just the last 15 messages can be really helpful. • Context Transfer Between Agents: The

BaseAgent.on_enter

method gives you the option to truncate chat context to include only the last N messages, while also letting you keep important system messages or function calls if you wish. • Filtering During Context Copy: With the

copy

method of

ChatContext

, you can exclude things like function calls, instructions, and empty messages. This way, you have fine-grained control over what context gets transferred. • Explicit Use in Agent Handoff: When doing warm transfers, the

TransferAgent

can receive a filtered and nicely summarized version of the conversation history by using the

copy

method with exclusion options and creating a clear textual summary. These approaches are designed to keep your conversations on point while making the best use of tokens.
