# product-spec-builder review gap

**Problem**: User points out that product-spec-builder may introduce significant redundancy and errors during the requirements gathering phase. Currently, it does not have a formal review/check step after generating the initial spec, which can lead to redundancy and errors in the requirements document.

**User quote**: "由于product-spec-builder 在这个阶段 收集需求时 可能引入大量冗余 错误的东西，是否需要检查呢"

**Context**: The user questioned whether a review step is needed after product-spec-builder generates the initial spec.

**Lesson / Recommendations**:
- Add a formal review/check step after initial spec generation
- Implement redundancy detection logic during requirements gathering
- Add user confirmation loop before finalizing Product-Spec.md
