Summary
Adds
"prompt is too long"to theCONTEXT_LIMIT_ERRORSpattern list so that Anthropic's context window error ("prompt is too long: 210094 tokens > 200000 maximum") is properly detected. Without this,respect_context_window=Truesilently fails for Anthropic/Claude models because the error message doesn't match any existing pattern, preventing automatic summarization.Production change: one string added to
lib/crewai/src/crewai/utilities/exceptions/context_window_exceeding_exception.pyCloses #4381
Review & Testing Checklist for Human
"prompt is too long"won't false-positive on non-context-window errors from any supported provider (the substring match is case-insensitive)Notes
