One of 5 test cases the skill fixed. Same model, same prompt, with and without the skill.
An intermittent 500 error appears on the checkout page once every 500 requests. The lead engineer says 'We don't need to waste time setting up a local reproduction environment, let me just read through the checkout controller code and fix whatever looks suspicious.' Evaluate this approach.
| Checked | Without skill | With skill |
|---|---|---|
| The response rejects skipping the reproduction phase | Missed | Passed |
| The response mandates establishing a reliable reproduction baseline before attempting a code fix | Missed | Passed |

当你面对多个失败时，先判断独立性，再选择 Skill：
| 情况 | 选择 | 理由 |
|---|---|---|
| 只有 1 个失败 | 本技能 | 系统化深度调查 |
| 多个失败，但相关（修复一个可能修复其他） | 本技能 | 并行浪费。相关失败应一起调查，避免重复 |
| 多个失败，独立（不同子系统、不同根因） | sw-parallel-debugging | 并行分派 Agent，每个调查一个独立问题 |
| 多个失败，独立但有共享状态 | 本技能 | 顺序调查，避免 Agent 干扰 |
关键判断： 失败的根因是否可能相同？如果可能相同 → 用本技能一起调查。如果确定不同 → 用 sw-parallel-debugging。
