There was a problem hiding this comment.
The fix works. I ran opencode run against a local OpenAI-compatible server that returns LiteLLM's ContextWindowExceededError with HTTP 400. On the base branch the session stops with the error and makes no compaction attempt. With this PR the error is classified as a context overflow and opencode sends the compaction request. packages/ai tests and the type check pass.
The new pattern is specific enough not to catch unrelated errors, and rate-limit messages are still excluded. The public API is unchanged.
No concerns.

Issue for this PR
Closes #44888
Type of change
What does this PR do?
When LiteLLM rejects a chat completion request for being too large context, it shows a special error message. Because it is special for LiteLLM, opencode simply aborts, and does not detect the error as being max context size reached.
How did you verify your code works?
Trying it locally, running the whole testsuite, using the patch every day.
