Summary

After upgrades through v2026.4.24 up to the most recent version, I've had error with openclaw like "...on windows absolute path required..." and significant slowdown in communication and response time with the agent. asked the agent to check the source of the delay and it indicates that it making a lot of session_status and session_history tool calls during even the simplest chat; this makes openclaw appear slow or unresponsive.

Steps to reproduce

Just use it on native windows with a local llm like I'm doing

Expected behavior

This was previously pretty quick especially when used with Qwen3.5-35b-a3b...so I expected the same "snappy" behavior or better, not worse.

Actual behavior

Agent is noticeably slowed.
