原则
- 输入表格只读，输出写入
PROJECT_ROOT。 - 普通结果汇总优先 CSV。
- 题目指定 XLSX、需保留公式、多工作表或模板结构时才使用 XLSX。
- 不覆盖题目原始附件和 Skill 文件。
读取与写入
import pandas as pd
# 第一行就是数据时必须显式使用 header=None。
data = pd.read_excel("data/input.xlsx", sheet_name=0, header=None)
assert len(data) == 7470, f"行数异常: {len(data)}"
result = pd.DataFrame({"方案": names, "目标值": values})
result.to_excel("results/结果.xlsx", index=False)
禁止依赖 pandas.read_excel() 默认的 header=0 猜测表头，否则第一行数据会被当成列名。未知表头结构或必须精确保留行时使用无隐式推断的读取工具：
from scripts.read_rows import read_excel_rows
rows = read_excel_rows(
"data/input.xlsx",
header=False,
expected_rows=7470,
)
assert rows[0][0] == 399.6747
读取后必须核对首行、末行、原始工作表有效行数和题目声明的记录数；行数不符时立即报错，不得静默继续建模。
使用模板时用 openpyxl.load_workbook() 打开，写入指定单元格后另存新文件。不要删除未知工作表、命名区域、公式或验证规则。
公式重算
openpyxl 不计算公式。修改含公式的工作簿后使用 LibreOffice 隔离重算：
python scripts/recalc.py "<PROJECT_ROOT>/results/结果.xlsx" 60
工具会：
- 使用唯一临时 LibreOffice 配置；
- 把重算结果写入临时目录；
- 检查常见 Excel 错误；
- 仅在成功后原子替换目标文件；
- 超时、失败或未生成输出时保留原文件。
DOCX 与 XLSX 共用的 OOXML/LibreOffice 基础代码位于 ../docx/scripts/office/，本工具不再维护重复副本。
检查
- 公式引用和范围正确。
- 工作表名、列名、数据类型和单位正确。
- 已显式声明是否有表头，首行、末行和预期数据行数均已核对。
- 无
#VALUE!、#DIV/0!、#REF!、#NAME?、#NULL!、#NUM!、#N/A。 - 结果与代码终端输出和论文表格一致。

Applicable for protocol discovery, collaborative protocol development, experiment tracking, lab protocol management, and scientific documentation.
Analyzes job descriptions and generates tailored resumes that highlight relevant experience, skills, and achievements to maximize interview chances
Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.
Build and distribute Expo development clients locally or via TestFlight
Use when you have a written implementation plan to execute in a separate session with review checkpoints
Data structure for annotated matrices in single-cell analysis. Use when working with .h5ad files or integrating with the scverse ecosystem. This is the data format skill—for analysis workflows use scanpy; for probabilistic models use scvi-tools; for population-scale queries use cellxgene-census.
Benchling R&D platform integration. Access registry (DNA, proteins), inventory, ELN entries, workflows via API, build Benchling Apps, query Data Warehouse, for lab data management automation.
Comprehensive molecular biology toolkit. Use for sequence manipulation, file parsing (FASTA/GenBank/PDB), phylogenetics, and programmatic NCBI/PubMed access (Bio.Entrez). Best for batch processing, custom bioinformatics pipelines, BLAST automation. For quick lookups use gget; for multi-service integration use bioservices.
