Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

InvalidDataCleaning
> This sub-skill covers one capability of the Excel workflow. For reading/counting/Parquet optimization, see the parent workflow SKILL.md.
Skill Steps
Step1 根据总行数判断是否数据量过大,若满足条件,则将 Excel 文件转换为 Parquet 格式提升读写效率,再读取数据进行后续分析。
import pandas as pd
file_path = "input_data.xlsx"
parquet_path = "temp_data.parquet"
# 读取 Excel 文件并转换为 Parquet 格式
xls = pd.ExcelFile(file_path)
dfs = []
for sheet in xls.sheet_names:
df_sheet = pd.read_excel(xls, sheet_name=sheet)
dfs.append(df_sheet)
# 合并所有 sheet 数据并写入 Parquet 文件
if dfs:
df_all = pd.concat(dfs, ignore_index=True)
df_all.to_parquet(parquet_path, engine='pyarrow', index=False)
# 读取 Parquet 文件用于后续处理
df = pd.read_parquet(parquet_path)
Step2 对目标文本字段中的特殊字符(如 #、-、数字)进行清洗,使用正则表达式仅保留中文字符。
import pandas as pd
import re
target_col = 'target_column' # 替换为实际需要清洗的列名
# 定义清洗函数
def clean_chinese_text(text):
if pd.isna(text):
return text
s = str(text)
# 提取所有中文字符(Unicode 范围:[一-鿿])
chinese_chars = re.findall(r'[一-鿿]', s)
cleaned = ''.join(chinese_chars)
return cleaned if cleaned else ''
# 应用清洗函数
if target_col in df.columns:
df[target_col] = df[target_col].apply(clean_chinese_text)
Step3 将清洗后的数据保存为表格文件(.xlsx),并在报告中提供本地下载链接。
import pandas as pd
# 保存清洗后的数据为 .xlsx 文件
output_path = "cleaned_data.xlsx"
df.to_excel(output_path, index=False)
print("清洗后的数据已保存至:", output_path)
# 生成本地文件下载链接
print("下载链接:", f"file://{output_path}")
