Today, when generating AGENTS.md using OpenCode Zen with GPT 5.4 and GPT 5.3-Codex, OpenCode created several subagents. As a result, multiple “Todo incomplete” messages popped up, along with text such as “Provider not found.” Eventually, I pressed Ctrl+C to close the window.
After checking OpenCode’s GitHub issues, I found a similar case: Agent loses context of AGENTS.MD rules when invoking parallel Task tool for batch processing · Issue #14633 · anomalyco/opencode
When encountering this issue, try switching to a different model. Later, after switching to GLM5, the error no longer occurred.
