When using Anthropic/Claude models with
respect_context_window=True, context window errors are not detected because Anthropic's error message format doesn't match the existing patterns.Anthropic error format:
"prompt is too long: 210094 tokens > 200000 maximum"Solution
Add
"prompt is too long"toCONTEXT_LIMIT_ERRORSlist to support Anthropic/Claude error detection.Note
Low Risk
Single-string match extension to error detection; minimal behavioral change limited to recognizing additional context-limit errors.
Overview
Improves context-window overflow detection by extending
CONTEXT_LIMIT_ERRORSwith the Anthropic/Claude error pattern"prompt is too long", soLLMContextLengthExceededErrorclassification triggers for Claude-style token limit messages (e.g., whenrespect_context_window=True).Written by Cursor Bugbot for commit baf0be2.
