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.
