From 15ea941fbec03fa1ab23488cc9b0b83f79a6a154 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Tue, 26 May 2026 12:53:39 +0000 Subject: [PATCH] fix(anthropic/messages): apply context_management on sync path; clear held stop_reason chunk in async iterator - Sync `anthropic_messages_handler` was silently dropping the `context_management` kwarg via `ANTHROPIC_ONLY_REQUEST_KEYS` after the polyfill was moved into the async handler. Bridge to the async dispatcher with `run_async_function` so `litellm.messages.create()` callers keep working (regressed e.g. `clear_tool_uses_20250919`). - In the streaming iterator's `__anext__` `StopIteration` handler, clear `self.holding_stop_reason_chunk` after capturing it (matches `__next__`) so a subsequent call doesn't re-emit the same chunk.
