What problem does it solve?
AscendC 算子精度调试帮助定位算子精度问题的根因。当算子精度测试失败（如 allclose 不通过、结果偏差、输出全零/NaN 等）时，提供从误差分布分析到代码审查、实验隔离、插桩定位再到修复验证的五阶段工作流。
Core Features & Use Cases
- Structured five-phase debugging workflow: 系统化定位根因，减少重复排查。
- 代码审查与定位要点：提供对算子主机/内核实现、 tiling、偏移等常见问题的检查清单。
- 实验隔离与插桩指导：逐步更改变量、加入 PipeBarrier、DumpTensor 等手段，确保可重复定位。
- 验证与回归：在修复后进行对比验证，确保误差消失且结果稳定。
Quick Start
Provide a failed test case details to trigger the five-phase plan, then instruct the AI to output a concrete root-cause plan and suggested fixes.
