Qwen Code Review Tool Misses Multi-line Duplicate Comments
wenshao · ghdev · 2026-08-15
A GitHub issue reports overlap detection bugs in Qwen Code's /review presubmit. The current logic relies on exact line matching (path, line), causing two types of misses:
- Range Blindness: Existing comments inside the range of a multi-line draft comment are ignored.
- Semantic Blindness: Genuine semantic duplicates are flagged as noConflict if anchored at different locations, requiring manual verification.
Suggestions include treating ranges as intervals and offering a mode to render full comment bodies.
