+## Changes
+
+Modified `tg_adapter.py`:
+```python
+# Before:
+message.sender = MessageMember(
+ str(_from_user.id),
+ _from_user.username or "Unknown",
+)
+
+# After:
+message.sender = MessageMember(
+ str(_from_user.id),
+ _from_user.full_name or _from_user.first_name or _from_user.username or "Unknown",
+)
+```
+
+## Testing
+
+The fix maintains backward compatibility by falling back to username if full_name is not available.

+## Summary
+
+Fixes #6661 - Streaming tool_call arguments lost when OpenAI-compatible proxy omits `index` field (e.g. Gemini)
+
+## Changes
+
+- Add missing `index` field to tool_call deltas before passing to `ChatCompletionStreamState.handle_chunk()`
+- Gemini and some OpenAI-compatible proxies (e.g. Continue) omit the `index` field
+- This caused `handle_chunk()` to reject the chunk and silently drop tool_call arguments
+
+## Testing
+
+✅ Docker sandbox test passed
+- Tool call without index: index=0 assigned
+- Tool call with existing index: original value preserved
+- Empty tool_calls handled
+- Empty choices handled
