[mylittlegitlab]

Pre-checks

• I have searched existing issues and this is not a duplicate.

Deployment Method

Docker

Steps to Reproduce

first turn let it read soul.md and only output yes
next turn ask it what's in the soul.md
I found it read the same file each turn.

Expected vs Actual Behavior

expected: only read once,
actual:read twice

Logs / Screenshots

i build a golang app to proxy model's http request, and found this.

i also let the ai analyze the bug(kimi, gpt5.5) -> websocket.py

i think it is not a feature, its a bug.
