data_analyzer

An interactive tool for examining CSV or JSON data. It identifies column types and calculates basic statistics, then supports filtering, sorting, grouping, and chart setup.

In plain words
What is it for?
Use it to analyze pasted data, check ranges, averages, missing values, and unique entries, query rows or groups, and prepare charts from chosen columns.
Why use it?
It provides a quick way to understand a dataset and inspect selected records without writing analysis code first.

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.

Security

Grade A, and why

data_analyzer 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 yesterday.

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 Analyzer

Interactive data analysis: paste CSV/JSON, auto-detect columns, compute statistics, and generate charts

Available Tools

  • format (string): Data format. Defaults to auto-detect.

enso_data_analyzer_chart

Generate chart configuration from analyzed data columns

Parameters:

  • chart_type (string): Chart type to generate

  • y_column (string): Column name for Y axis / values

enso_data_analyzer_query

Filter, sort, or group the analyzed dataset

Parameters:

  • filter_column (string): Column to filter on
  • filter_op (string): Filter operator
  • filter_value (string): Value to filter by
  • sort_column (string): Column to sort by
  • sort_dir (string): Sort direction

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.

data_analyzer is a skill published in the GitHub repository Proxy2021/Enso (5 stars, last pushed 3mo ago), licensed MIT. It adds 24 tokens to every session and 275 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
