History Scoping and Context
Space Types in Google Chat
Hana can be used in:
- Direct messages.
- Unthreaded spaces.
- Threaded spaces.
How Context Is Scoped
Inside Threads
When invoked inside a thread, Hana prioritizes that thread's conversation context so responses stay focused on the topic.
Outside Threads
When invoked in non-threaded conversation, Hana uses a bounded recent window and relevant context signals. Exact window size can vary by plan and system behavior.
Practical Guidance
- Use threads for ongoing topics and decisions.
- Keep each thread focused on one topic.
- Start a new thread when context drifts.
- Include a time window in prompts for better precision.
Runtime Behavior
Hana reads context at invocation time. Message edits/deletions and latest thread state can affect responses accordingly.
Performance Consideration
Very long threads can reduce response quality and increase latency. If a thread becomes noisy, summarize and start a fresh thread.
