Fixes #7968
Problem
ChatCompletionCache._check_cache()computed the SHA-256 cache key from messages and tools only. Calls with identical messages/tools but differenttool_choicevalues (e.g.,autovsnone) incorrectly returned stale cached results.Fix
Include
tool_choicein the cache key computation.Changes
python/packages/autogen-ext/src/autogen_ext/models/cache/_chat_completion_cache.py: includetool_choicein keypython/packages/autogen-ext/tests/models/test_chat_completion_cache.py: addtest_cache_key_includes_tool_choiceVerification
Cache miss now correctly occurs when
tool_choicechanges.
