OpenCode does not work reliably on NixOS #28964

Description

Hi,

I have reported this on NixOS too: NixOS/nixpkgs#522943.

But I thought sharing it here as well:

From time to time, the logs show some errors:

ERROR service=file.watcher error=libstdc++.so.6: cannot open shared object file: No such file or directory failed to load watcher binding

cleanup failed
WARN service=default error=Operation timed out after 5000ms worker shutdown failed

At times, when a command runs (e.g. cargo build), OpenCode hangs and the progress-indicator spins indefinitely. I am not sure, but it may be due to this. Or perhaps OpenCode does not configure DeepSeek models correctly.

For example, in Pi, the requiresReasoningContentOnAssistantMessages option should be set to true for DeepSeek (see https://api-docs.deepseek.com/quick_start/agent_integrations/pi_mono).

Steps to reproduce

1. Install OpenCode in NixOS via the NixPkgs unstable channel
2. Configure it to use DeepSeek V4 Flash
3. Run a lengthy session that involves many bash tool calls
4. From time to time edit a file using an external editor
