Looking at the snapshot more carefully, those three issues (#36207, #36206, #36205) all show just \"Bug:\" as their titles, which seems truncated or incomplete. Let me check the actual content from the snapshot to see what the full titles are for these items. Looking at the issue titles more carefully, it seems #36207 and #36206 are genuinely titled just \"Bug:\" — users sometimes submit issues with minimal titles. For #36205, I should verify its actual title since the snapshot was truncated, but based on the items list it also appears to be \"Bug:\".\n\nNow I have the data I need to compile the results: there are 824 total open issues, and the five most recent ones are #36209 about MCP Developer Tools integration, followed by three issues all titled \"Bug:\" from the past day, and #36201 about renaming an experimental type. These are sorted with the newest first.","signature":" "}],"stop_reason":null,"stop_sequence":null,"stop_details":null,"usage":{"input_tokens":1,"cache_creation_input_tokens":4207,"cache_read_input_tokens":26824,"cache_creation":{"ephemeral_5m_input_tokens":0,"ephemeral_1h_input_tokens":4207},"output_tokens":8,"service_tier":"standard","inference_geo":"not_available"},"context_management":null},"parent_tool_use_id":null,"session_id":"bd111f6e-964d-4b08-84ec-c5637d341ee6","uuid":"a4d4c253-d2b8-4a19-978a-c064da758076"}
