+> ### 🐛 Fix Claude Thinking Tokens Invisible in Passthrough Mode
+
+### Bug Fixes
+
+- **Claude thinking tokens not visible (#289)** — When routing through Antigravity OAuth or any Claude provider, thinking blocks were being emitted as regular `delta.content` with `<think>/<\/think>` XML wrappers. Fixed: now correctly maps `thinking_delta` events to `delta.reasoning_content` so clients like Claude Code, Cursor, and Windsurf display the thinking panel properly.
