data-analysis SKILL.md skillA

data-analysis from lynricsy/hyperskills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add lynricsy/hyperskills/data-analysis@v2026.10.15

Pins v2026.10.15 in mdr.lock. Pin the fingerprint instead.

Analyzes tabular datasets with pandas, Polars and DuckDB for reliable conclusions.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# data-analysis

Paths below are relative to this skill's directory.

## Scope

Local tabular data to a defensible, reproducible answer: data contracts,
cleaning decisions, joins, measures, comparisons, uncertainty, and execution
that preserves those meanings as data grows. Keep the existing engine and
public return type unless the task explicitly calls for a migration.

Not covered:

- Database locks, WAL, backups, transactions, indexes, or service operations:
  use `sqlite`, `postgres`, or the relevant database skill.
- Creating or editing an Excel, Word, PowerPoint, or PDF deliverable: use
  `office`. Reading a supplied tabular export for analysis remains here.
- General Python packaging, typing, and asynchronous code: use `python`.
- Training, fine-tuning, or model-serving infrastructure: use `ml-training`.
- Domain-specific scientific formats, proprietary connectors, and distributed
  platform administration. Do not install a connector to avoid reading an
  already supplied local file.

## Core rules

1. State the population, observation unit, metric grain, and record identity before aggregating; a row is not necessarily an independent entity.

How to install

The exact contents, by fingerprint

mdr add lynricsy/hyperskills/data-analysis@sha256:a3a714d9ac8b763b

The line at the top of this page pins the label v2026.10.15, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
