What it does
Perf Profiler is an agent skill from laolaoshiren/claude-code-skills-zh. 基于可复现基线和 profiler 证据分析性能问题。用于用户要求定位慢接口、慢任务、慢查询、内存或网络瓶颈，制定优化方案，或验证优化收益时；区分实测结论与静态推断，不虚构耗时和提升比例，生产环境操作需明确授权。
Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Performance optimization. The repository describes itself as: 面向中文开发者的 Claude Code Skills / Agents / Plugins 精选与原创技能库｜按场景分类｜复制即装｜持续更新. The licence is MIT.
When your agent uses it

Example prompts
- “/perf-profiler”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 633f21c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Perf Profiler loads about 385 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 61 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

性能分析助手
工作流程
1. 明确目标与边界
先确认或从项目中核实：
- 目标指标，如延迟、吞吐量、CPU、内存、查询次数或包体积。
- 可复现的场景、数据规模、运行环境、版本和关键配置。
- 用户允许分析和修改的范围，以及是否可以运行负载或 profiler。
没有明确目标时，先用现有监控、benchmark 或用户现象缩小范围，不把“代码看起来慢”当成瓶颈结论。
2. 建立基线
优先复用项目已有的启动、benchmark、trace 和 profiling 配置。在相同环境、数据和负载下记录：
- 预热方式、并发度、重复次数和统计口径。
- 代码版本、依赖版本及影响结果的配置。
- 原始测量值和波动范围；条件允许时保留机器可读结果。
无法运行项目时，只能进行静态分析，并把发现标为“待验证候选”。
3. 收集证据
按技术栈选择 profiler、trace、火焰图、查询计划、网络时序或内存快照，定位时间或资源实际消耗的位置。常见维度包括：
- 代码：算法复杂度、重复计算、分配热点、同步阻塞和并发争用。
- 数据库：N+1 查询、扫描量、索引使用、锁等待和连接池状态。
- 网络：请求瀑布、有效载荷、压缩、缓存命中和外部服务延迟。
复杂度分析和代码审查只能证明风险，不能单独证明运行时影响。
4. 提出最小改动
- 将建议绑定到具体证据、文件或调用链。
- 说明正确性、内存、吞吐量、维护成本和兼容性方面的权衡。
- 优先处理证据最强、影响最大的热点；不同时改动多个无法独立归因的因素。
- 为代码、配置和数据结构变更准备验证与回滚方式。
5. 同条件复测
修改后使用与基线一致的环境、数据、负载、预热和统计口径复测，并运行受影响功能的正确性测试。报告原始结果、波动、差异和尚未控制的变量。
只有真实完成同条件测量后，才能写耗时、百分比或“已改善”等确定性结论。
证据等级
- 已测量：有可复现基线、profiling 证据和实际结果。
- 静态推断：由复杂度、调用关系或配置推导出的候选问题，尚未实测。
- 待验证：缺少环境、数据或权限，当前无法判断影响。
安全与授权边界
- 默认只在本地或用户明确指定的测试环境进行只读分析。
- 生产环境 profiling、压测、
EXPLAIN ANALYZE及索引、缓存、连接池、CDN 或外部服务配置变更必须获得明确授权。 - 不在报告中暴露生产数据、凭据或含敏感信息的 profiling 产物。
- 不为得到漂亮数字而删除正确性检查、降低数据规模或改变统计口径。
- Windows 与 Linux 优先使用项目已有工具；平台特定命令需说明适用范围或提供等价方法。
