Steps to reproduce

1.Configure openclaw to start with ollama kimi k.2.5 cloud.
2. Request agent to test tools.
3. First try will work
4. After all toolcalls will break

When using kimi-k2.5:cloud via Ollama 0.17.4 with OpenClaw 2026.2.26, tools intermittently fail with Tool not found or sandbox unavailable errors. Switching to glm-5:cloud resolves the issue.

Environment:
• OpenClaw: 2026.2.26
• Ollama: 0.17.4
• Model (affected): kimi-k2.5:cloud
• Model (working): glm-5:cloud
• Host: Raspberry Pi 5, arm64

Frequency:
• 5+ failure cycles in 15 minutes
• ~30-40% of tool calls failed
• No failures after switching to glm-5 (2+ hours stable)

Timeline:
14:45 - Session started (kimi)
14:48 - First errors
14:49-14:52 - Multiple failure cycles
15:09 - Switched to glm-5
15:09+ - Stable

Toolcalling with other models seems fine.
