quality-detect-regressions

Compare current quality metrics against a stored baseline to detect regressions in tests, coverage, type errors, linting, and dead code. Enforces quality standards by blocking task completion when metrics degrade beyond tolerance thresholds.

| Metric | Rule | Tolerance | Regression If |

| Tests passed | Must be >= baseline | None | current < baseline | | Coverage | Must be >= baseline - 1% | 1% | current < baseline - 1% | | Type errors | Must be baseline | | Linting | Must be baseline | | Dead code | Must be baseline + 2% |

将当前质量指标（测试、覆盖率、类型错误、linting、死代码）与基线进行比较并检测回归。在任务完成后、标记任务完成之前或合并/提交之前主动调用。阻止回归以防止质量下降。在完成任务、验证更改或对照基线检查质量回归时使用。 来源：dawiddutoit/custom-claude。
