What is data-analysis?

Tools for examining CSV and JSON data, including summary statistics, row filtering, grouped totals, and relationships between numeric columns.

Use it to describe a table, select matching rows, calculate sums or averages by group, count records, or compare numeric columns.

It removes the need to write common data-cleaning and calculation code for each dataset.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00022	$0.00177
Opus 5.5	$0.00009	$0.00071
Sonnet 5.5	$0.00004	$0.00035
Haiku 4.5	$0.00002	$0.00018

Security

Grade A, and why

data-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/main.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Data Analysis Skill

Perform statistical analysis on tabular data using pandas and numpy.

Supported Operations

describe: Summary statistics (mean, std, min, max, etc.)
filter: Filter rows by column conditions
aggregate: Group-by aggregation (sum, mean, count, etc.)
correlate: Correlation matrix between numeric columns

Usage

{"operation": "describe", "data": [[1,2],[3,4]], "columns": ["a","b"]}

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
