Symptom

Section titled “Symptom”
Error output
当我打开路由就会丢失，并失去自动压缩功能
English translation

When I turn on routing, it disappears, and I lose the automatic compaction feature.

Cause

Section titled “Cause”

The reporter says context window information appears normally when routing is off. After enabling routing, the information disappears and automatic compaction is unavailable. The report also says it appears normally with a regular model such as gpt-5.5, while setting only the routing protocol does not work; a model must also be added. The issue does not identify a root cause or confirmed fix.
