[Web UI] Task never stops — agent runs indefinitely when using opencode serve #26365
Closed as not planned
Description
Bug Description
When using OpenCode via the web interface (opencode serve), tasks never stop. The agent enters an infinite loop and continues running indefinitely, even after the task appears to be completed. The TUI stops correctly — this issue only occurs in the web UI.
Steps to Reproduce
- Start OpenCode:
opencode serve - Open browser, access web UI via SSH port forwarding
- Give the agent a coding task
- Agent completes the task but never stops — keeps running in an endless loop
Expected Behavior
Agent should stop after completing the task.
Actual Behavior
Agent runs indefinitely. Web UI shows task as still active with no way to stop it. No error message, agent just keeps "thinking".
Environment
- OpenCode Version: 1.14.29
- Server OS: Linux (Ubuntu)
- Browser: Chrome 148 on Windows 10
- Access method: SSH port forwarding to
opencode serve
Additional Context
- The same task works correctly in TUI mode
- Only happens in web UI mode
- Wastes API credits as the agent keeps making calls in the loop
- This makes the web UI unusable for any meaningful work
