深度数据洞察与报表工程技能 (dsh-data-craft)
当面对数据分析、报表清洗、多维透视或业务异动归因时,本技能提供零外部依赖、极致性能的专业数据工程交付,包含可视化数据管道与数据工作留痕机制。
🧭 可视化数据处理工作流 (Data Pipeline Trace)
每次执行数据清洗与分析时,首先内联呈现数据处理管道流:

1. 零依赖极速数据分析
- 可调用
/sdcard/DeepSeekHarness/tools/work-trace.mjs中的analyzeDataset()或parseCSV()进行秒级计算; - 必须输出关键统计量:样本总量、有效数值量、均值 (Avg)、中位数 (Median)、P95 分位数、极值范围 (Min~Max);
- 多维分组透视:按核心维度进行降序排行与占比分布。
2. 聊天内原生可视化图表 (Zero-jump Visuals)
- 时序走势 / 分组对比:使用标准
mermaid绘制折线图、柱状图或饼图; - 业务漏斗与流转:使用 Mermaid
graph TD或flowchart绘制带转化率标签的漏斗图。
3. 业务异动深度归因简报 (Root Cause Insights)
- 异动判定:明确指出哪些指标超出预期波动范围(如 > 15% 异动);
- 三维归因:从 流量端 (渠道变化)、转化端 (体验/流程)、供给端 (客单价/库存) 进行逻辑严密的下钻归因;
- 可落地建议:给出清晰的 Next Steps 动作清单。
📋 必带工作留痕卡片 (Data Audit Card)
在交付物末尾,必须输出标准化的数据留痕审计卡片:

### 📊 数据分析留痕审计卡片 (Data Craft Audit Card)
- **任务编号**:`DC-20261007-002`
- **数据源**:`user_orders_202610.csv` (共计 45,210 行样本)
- **核心指标**:
* **GMV 汇总**:¥1,428,500.00 (环比 +12.4%)
* **笔单价 (Avg)**:¥186.20 | **P95 笔单价**:¥680.00
* **主要异常**:华东大区在 10-04 出现转化率断崖下跌 (-24.1%)
- **主要结论与归因**:10-04 华东网关超时导致下单流程阻断,建议优先排查路由节点。
- **归档时间**:2026-10-07 18:42 (DSH Data Craft Engine)
---Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
