What it does
CSV Data Summarizer is an agent skill from coffeefuelbump/csv-data-summarizer-claude-skill. Analyzes CSV files, generates summary stats, and plots quick visualizations using Python and pandas.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files (for example `README.md`, `analyze.py` and `resources/README.md`).
It sits in Data & Analytics, covering CSV and tabular files and DataFrames. It works with pandas and Python. The repository describes itself as: A Claude Skill that automatically analyzes uploaded CSV files — generating summary statistics, detecting missing data, and creating quick visualizations using Python and pandas.
When your agent uses it
- Tasks that involve CSV and tabular files
- Tasks that involve DataFrames
Example prompts
- “Use the csv-data-summarizer skill to analyz CSV files, generates summary stats, and plots quick visualizations using Python and pandas”
- “/csv-data-summarizer”
Requirements
- Python 3
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Run the comprehensive analysis
- Generate ALL relevant visualizations
- Present complete results
- NO questions, NO options, NO waiting for user input
What it can do on your machine
Read from SKILL.md and the folder at commit 9b3affd. 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 script files (Python), which the agent can run.
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 Data Summarizer loads about 1.4k tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 701 words of instructions outside code blocks.
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 701 words (~1,417 tokens).
