dsh-speed-up-perf SKILL.md skillA
dsh-speed-up-perf from qufei1993/skills-hub is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add qufei1993/skills-hub/dsh-speed-up-perf@git:20261030.1b17503Pins git:20261030.1b17503 in mdr.lock. Pin the fingerprint instead.

调查性能问题或优化实际测量的用户路径时使用，建立优化前后对照，保留正确性、失败行为和真实运行证据。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 优化实际测量的用户路径性能 阅读[项目上下文](references/project-context.md)和[验证证据](references/evidence.md)。明确真实负载和独立正确性判据前，不开始优化。 1. 确定用户可见操作、入口、代表性输入规模、环境和性能现象。定义正确性、延迟或吞吐量，以及有关的峰值和保留内存指标。分开测冷启动与预热后的稳定状态。 2. 在真实产物上建立基线。记录版本、构建、运行环境、输入、命令、重复次数和结果分布，不能只取最快一次；保留可观察输出。 3. 用性能分析或测量代码定位怀疑的瓶颈，验证一个因果假设。加入错误对照，区分真正瓶颈、测量噪声和悄悄省略的工作。不得牺牲必需记录、顺序或错误行为。 4. 实施有依据的最小优化。涉及缓存时，按[生命周期](references/lifecycle.md)验证缓存键是否完整、失效规则、存续时间和保留内存上限。 5. 重新构建，在等价条件下复测；有帮助时交替测优化前后。独立验证输出等价和失败行为。变化可能在冷路径、热路径或内存之间产生取舍时，检查相应指标。同时报告收益和退步；噪声淹没差异时，说明改进尚未证实。 报告实际数字、测量条件、正确性证据和取舍。不得将复杂度估算、微基准测试或省略工作得到的结果，当作已经测得的端到端提升。

How to install
mdr add qufei1993/skills-hub/dsh-speed-up-perf@sha256:e06cdfe9368be22eThe line at the top of this page pins the label git:20261030.1b17503, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
