What it does

The skill is one stage in a multi-step workflow for mathematical modeling competition papers, written in Chinese. Before starting, the agent runs a workflow guard script to confirm which stage the project is in, and if the guard reports a failure it stops and goes back to fill in earlier stages. It reads the input manifest, the problem analysis and the model route, and processes only attachments marked as raw data that can be used for modeling.

Outputs are a load report, a data plan, a visualization plan and a figure index, plus cleaned data and figures when there is data to process. The Python scripts in scripts/, including clean_data.py, visualize_data.py and run_pipeline.py, are treated as code-level templates rather than fixed programs: the agent adapts them to each competition's tables, units and chart needs, and template charts must never be presented as final results. Afterward it hands over to a quality-assurance auditor skill and records progress in a workflow memory file.

When your agent uses it

  • Cleaning raw or scraped data attached to a modeling competition problem
  • Generating exploratory charts and a figure index for a modeling paper
  • Continuing a paper workflow that still needs a data plan and visualization plan

Example prompts

  • “Clean the attached problem data, handle the missing and abnormal values, and plot the distributions.”
  • “Build the visualization plan and figure index for our modeling paper.”

Requirements

  • Python
  • The paper-workflow-orchestrator and context-memory-keeper skills from the same repository

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. 自动发现数据源:自动扫描 problem_files/(赛题附件)或 crawled_data/(爬虫数据)目录。
  2. 读取诊断报告:先运行 robust_loader.py,生成 paper_output/data_cleaned/load_report.json,记录 xlsx/csv/json 结构与 PDF 诊断结论;脚本会优先读取…
  3. 数据与图表计划:生成 data_plan.json、visualization_plan.json 与 figure_index.json,作为后续 QA 和正文生成的图表证据交接单。
  4. 智能清洗
  5. 自动可视化
  6. 规范化输出:所有清洗后的数据和图表统一保存到 paper_output/ 目录下,方便后续论文写作调用。

What it can do on your machine

Read from SKILL.md and the folder at commit 7712876. 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

    Ships 7 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    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

Math Modeling Data Cleaning and Charts loads about 1.7k tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 275 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~26
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

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); the scripts in this folder are not scanned.

数据清洗与可视化 (Data Cleaning and Visualization)

全局流程协作约束(长对话防漂移)

  • 本 skill 不得作为孤立入口。用户要求完整论文、生成 Word、继续流程或不确定阶段时,先回到 paper-workflow-orchestrator 判断当前 S0-S8 阶段。
  • 启动或继续本 skill 的正式任务前,必须运行:
    bash
    python .trae/skills/paper-workflow-orchestrator/scripts/workflow_guard.py --skill data-cleaning-and-visualization
  • 如果输出 [WORKFLOW FAIL] 或报告 status != "PASS",停止本 skill,按 paper_output/qa/workflow_guard_report.json 的失败项回补前置阶段,不得凭记忆继续。
  • 本 skill 只写入自己契约范围内的 paper_output/ 产物;完成后必须回到 paper-workflow-orchestrator 判断下一步,并用 context-memory-keeper 记录已完成产物、阻塞项和下一步。
  • 长对话中如果上下文变长、阶段不确定或用户分开调用 skill,先运行:
    bash
    python .trae/skills/paper-workflow-orchestrator/scripts/workflow_guard.py --status
    再读取 paper_output/qa/workflow_guard_report.json、paper_output/preflight_report.json、paper_output/input_manifest.json、paper_output/results/run_manifest.json 和本 skill 的上游 JSON 契约,按报告里的 recommended_skill 与 next_action 继续。
  • 继续流程前,必须把 paper_output/context/workflow_memory.json 视为长期断点记录;若其中的 current_step、next_step、recommended_skill 与 workflow_guard.py --status 不一致,以 guard 报告为准。
  • 每次完成本 skill 的产物后,先回到 paper-workflow-orchestrator 或运行 workflow_guard.py --status,再更新 workflow memory:
    bash
    python .trae/skills/context-memory-keeper/scripts/update_workflow_memory.py
    更新后读取 paper_output/context/workflow_memory.json / .md,确认下一步和推荐 skill 已记录。

执行契约

  • 上游输入:优先读取 paper_output/input_manifest.json、paper_output/step1/problem_analysis.json 与 paper_output/plan/model_route.json;正式流程只处理 manifest 中标为 raw_data 且 usable_for_modeling=true 的附件。
  • 必须输出:paper_output/data_cleaned/load_report.json、paper_output/plan/data_plan.json、paper_output/plan/visualization_plan.json、paper_output/figure_index.json;有可处理数据时同步输出 paper_output/data_cleaned/ 与 paper_output/figures/。
  • 下游交接:quality-assurance-auditor 审计数据/图表证据;S7 写作计划直接引用 figure_index.json、表格索引和结果契约。tasks.json 仅供 legacy/quickstart。
  • 推荐下一步:完成数据和图表计划后进入 quality-assurance-auditor 生成任务清单;完整论文目标应回到 paper-workflow-orchestrator 判断后续阶段。
  • 失败回退:若没有可处理数据文件,仍尽量根据题意和模型路线生成计划文件;不得把模板图表直接当作最终真实结果。

本技能用于自动处理数学建模中的原始数据,执行标准化的清洗流程,并生成基础的数据探索性分析(EDA)图表。旨在减少手动处理数据的繁琐步骤,快速获取数据的统计特征和分布情况。

重要定位:脚本是代码级提示词

数学建模赛题的数据表结构、字段名称、单位口径和图表需求通常都不同,因此本技能的 scripts/ 不应被理解为所有赛题通用的固定程序。它们的核心价值是提供高质量的数据处理与图表生成样板:包括输入输出目录、清洗步骤、图表尺寸、配色、标注、保存路径和论文引用口径。

真实赛题中,应先分析当前附件的数据格式和建模需求,再引用 scripts/ 中的写法二次修改,或让 Agent 读取这些脚本后重新生成适配当前赛题的新代码。

功能特性

  1. 自动发现数据源:自动扫描 problem_files/(赛题附件)或 crawled_data/(爬虫数据)目录。
  2. 读取诊断报告:先运行 robust_loader.py,生成 paper_output/data_cleaned/load_report.json,记录 xlsx/csv/json 结构与 PDF 诊断结论;脚本会优先读取 paper_output/input_manifest.json,跳过 result_template、题面文档和不可用于建模的附件。PDF 表格抽取只作诊断,不直接视为可信原始数据。
  3. 数据与图表计划:生成 data_plan.json、visualization_plan.json 与 figure_index.json,作为后续 QA 和正文生成的图表证据交接单。
  4. 智能清洗:
    • 自动识别并转换数值列。
    • 处理缺失值(数值型填补均值/中位数,分类型填补众数)。
    • 去除全空行/列。
    • 简单的异常值标记/处理。
  5. 自动可视化:
    • 数值变量:直方图、箱线图。
    • 分类变量:柱状图。
    • 多变量关系:相关性热力图、散点矩阵。
    • 论文级图表样板:预测对比图、残差分布图、方案/模型对比图、敏感性分析图、权重图、排序图、热力图、聚类散点图。
  6. 规范化输出:所有清洗后的数据和图表统一保存到 paper_output/ 目录下,方便后续论文写作调用。

脚本清单

本技能包含以下核心脚本,位于 .trae/skills/data-cleaning-and-visualization/scripts/ 目录下:

  • scripts/robust_loader.py

    • 何时用:任何正式数据清洗、建模或绘图之前,先诊断附件是否可读、哪些 sheet/字段可用、PDF 是否需要人工转表。
    • 做什么:优先读取 paper_output/input_manifest.json,只对标为 raw_data 的 xlsx/xls/csv/tsv/json 生成结构报告;对 PDF 只生成文本/表格诊断,不把 PDF 自动抽取结果当作可信数据;输出 paper_output/data_cleaned/load_report.json,并记录当前 input_manifest_sha256。manifest 变化后必须重跑 loader。
  • scripts/run_pipeline.py

    • 何时用:用户提供赛题数据或完成爬虫后,需要自动完成清洗和绘图时。这是最常用的辅助脚本。
    • 做什么:依次生成数据/图表计划、调用清洗和绘图脚本,并在 paper_output/ 下生成完整结果。
  • scripts/build_data_visualization_plan.py

    • 何时用:已有 problem_analysis.json 或 model_route.json,需要先明确“哪些数据支撑哪些问题、哪些图表放在哪里”时。
    • 做什么:读取赛题分析、模型路线和现有数据文件,输出 paper_output/plan/data_plan.json、paper_output/plan/visualization_plan.json 与 paper_output/figure_index.json。
  • scripts/clean_data.py

    • 何时用:只需要清洗数据,不需要绘图,或者需要自定义清洗逻辑时。
    • 做什么:读取原始数据,输出清洗后的 CSV/Excel 文件到 paper_output/data_cleaned/。
  • scripts/visualize_data.py

    • 何时用:已有清洗好的数据,需要重新生成图表时。
    • 做什么:读取 paper_output/data_cleaned/ 下的数据,生成基础 EDA 图表到 paper_output/figures/。
  • scripts/paper_figure_templates.py

    • 何时用:Agent 需要生成论文级图表代码时,优先读取本文件作为代码样板。
    • 做什么:提供预测对比、残差分布、模型/方案对比、敏感性分析、指标权重、综合得分排序、热力图、散点图等函数模板。无法读取真实数据时返回结构化 placeholder 状态,不生成可冒充真实结果的 PNG。
  • scripts/generate_paper_figures_from_plan.py

    • 何时用:已有 visualization_plan.json 和清洗后的 CSV,希望先生成一版论文级图表草稿时。
    • 做什么:按图表计划调用 paper_figure_templates.py,把真实可生成图写入 paper_output/figures/fig_*.png,并在 figure_index.json 中记录 ok、placeholder 和 status。任何 placeholder 都不能通过正式 evidence gate。

输出结构

运行后,将在 paper_output 目录下生成以下内容:

paper_output/
├── plan/
│   ├── data_plan.json       # 数据字段、清洗任务与子问题链接
│   └── visualization_plan.json # 建议图表、图题、用途与输出路径
├── figure_index.json        # 图表计划索引,供 QA 和正文生成核对
├── data_cleaned/       # 清洗后的数据文件
│   ├── load_report.json # 附件读取诊断报告
│   ├── dataset1_cleaned.csv
│   └── ...
├── figures/            # 生成的可视化图表
│   ├── fig_q1_1.png     # 按 visualization_plan 生成的论文级图表草稿
│   ├── fig_q1_2.png
│   ├── dataset1/
│   │   ├── dist_column_A.png
│   │   ├── heatmap.png
│   │   └── ...
│   └── ...

目录约定(与项目全局对齐)

  • 输入数据优先放在 problem_files/(赛题附件)与 crawled_data/(补充/爬虫数据)。
  • 本技能只写入 paper_output/,不会改动原始数据文件。
  • data_plan.json 与 visualization_plan.json 是交接单,不是固定代码。Agent 应根据它们和当前附件结构二次生成或修改真实建模代码。
  • paper_figure_templates.py 生成的是论文图表代码样板。若当前赛题已经有真实模型输出,应优先把真实结果表接入这些模板,而不是直接把模板图当最终结果。
  • figure_index.json 中 placeholder=true、ok=false、exists=false、失败消息或空文件都表示图表证据未完成;不得仅凭索引条目存在就继续正式写作。

前后衔接

  • 后续通常接:quality-assurance-auditor(生成任务清单)→ paper-micro-unit-generator(生成与合并)。
  • 若要继续到论文草稿:回到 paper-workflow-orchestrator。

约束(必须遵守)

  • Memory Interaction (必做):
    • 完成清洗后,必须调用 context-memory-keeper,记录“数据质量概况(样本量/缺失情况)”与“关键图表路径”到 Short-term Workbench。
  • 本技能只允许读取:problem_files/ 与 crawled_data/;只允许写入:paper_output/。
  • 正式流程读取附件前必须先生成 paper_output/input_manifest.json 与 paper_output/data_cleaned/load_report.json;Agent 不得跳过 manifest 直接复述 PDF 表格内容或把 result*.xlsx 当作原始数据。
  • 任何需要在论文中出现的图表,必须从 paper_output/figures/ 引用,避免散落在根目录或附件目录。
  • 若用户目标是“产出完整论文草稿”,本技能结束后必须进入:quality-assurance-auditor 或直接回到 paper-workflow-orchestrator,否则会出现“有图但无正文/有正文但无任务清单”的断链。
