A skill your agent uses when reading sensor data from CSV files, writing simulation results to CSV, processing time-series data with pandas, or handling missing values in datasets.

  • Reading sensor data from CSV files
  • SKILL.md covers Reading CSV, Handling Missing Values, Accessing Data and Writing CSV, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Writing simulation results to CSV

What it does

CSV Processing is an agent skill from benchflow-ai/skillsbench. Use this skill when reading sensor data from CSV files, writing simulation results to CSV, processing time-series data with pandas, or handling missing values in datasets.

Its SKILL.md is about 460 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 Data & Analytics, covering CSV and tabular files, Data cleaning and DataFrames. It works with pandas. The repository describes itself as: SkillsBench evaluates how well skills work and how effective agents are at using them. The licence is Apache-2.0.

When your agent uses it

  • Reading sensor data from CSV files
  • Writing simulation results to CSV
  • Processing time-series data with pandas
  • Handling missing values in datasets

Example prompts

  • “/csv-processing”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit 9a1f4dd. 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 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

CSV Processing loads about 455 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 18 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~47
When it runs · the whole SKILL.md, loaded when a task matches
~455

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.

CSV Processing with Pandas

Reading CSV

python
import pandas as pd

df = pd.read_csv('data.csv')

# View structure
print(df.head())
print(df.columns.tolist())
print(len(df))

Handling Missing Values

python
# Read with explicit NA handling
df = pd.read_csv('data.csv', na_values=['', 'NA', 'null'])

# Check for missing values
print(df.isnull().sum())

# Check if specific value is NaN
if pd.isna(row['column']):
    # Handle missing value

Accessing Data

python
# Single column
values = df['column_name']

# Multiple columns
subset = df[['col1', 'col2']]

# Filter rows
filtered = df[df['column'] > 10]
filtered = df[(df['time'] >= 30) & (df['time'] < 60)]

# Rows where column is not null
valid = df[df['column'].notna()]

Writing CSV

python
import pandas as pd

# From dictionary
data = {
    'time': [0.0, 0.1, 0.2],
    'value': [1.0, 2.0, 3.0],
    'label': ['a', 'b', 'c']
}
df = pd.DataFrame(data)
df.to_csv('output.csv', index=False)

Building Results Incrementally

python
results = []

for item in items:
    row = {
        'time': item.time,
        'value': item.value,
        'status': item.status if item.valid else None
    }
    results.append(row)

df = pd.DataFrame(results)
df.to_csv('results.csv', index=False)

Common Operations

python
# Statistics
mean_val = df['column'].mean()
max_val = df['column'].max()
min_val = df['column'].min()
std_val = df['column'].std()

# Add computed column
df['diff'] = df['col1'] - df['col2']

# Iterate rows
for index, row in df.iterrows():
    process(row['col1'], row['col2'])
