Core Concepts
Auto-compaction
Auto-compaction summarizes session history to retain meaning while freeing room for continued work.
What auto-compaction is
Auto-compaction is an automatic context summarization pass. Instead of carrying full long history forever, Spatial keeps core meaning in a compact form.
This helps maintain continuity while making space for new conversation and reducing context overload.
When it runs
- Default threshold is 85% context usage.
- It runs when usage reaches or exceeds that threshold.
- It is designed for coding requests and skipped for max-mode requests.
- Supported threshold range is 5% to 95% where configurable.
Current default
The current default threshold is 85%.
What to expect after compaction
- Core intent and recent important user context are retained.
- You can continue the session without manually rebuilding everything.
- If precision is critical, restate constraints after compaction for strongest alignment.
