exploring-data SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
exploring-data from oaustegard/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add oaustegard/claude-skills/exploring-data@v0.2.1Pins v0.2.1 in mdr.lock. Pin the fingerprint instead.

Exploratory data analysis. Use when users upload .csv/.xlsx/.json/.parquet files or request "explore data", "analyze dataset", "EDA", "profile data". Small files get ydata-profiling HTML/JSON reports; large files (over 200MB or 5M rows) get fixed-memory DuckDB/sketch profiling. Also covers near-duplicate row detection, cross-file key overlap ("can these join?"), dataset drift vs a stored baseline, and time-series profiling.
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
# Exploring Data
## 0. Route by size FIRST
```bash
ls -la <filepath> # or: wc -l for row estimate
```
- **< 200MB and < ~5M rows** → ydata-profiling path (section A). Exact stats, interactive HTML.
- **Larger** → large-file path (section B). ydata-profiling loads everything into pandas and will crawl or OOM; the DuckDB/sketch path runs in fixed memory at any size.
- **Task-specific ops** (any size): duplicates, join feasibility, drift → section C.
## A. Standard path (ydata-profiling)
### 1. Check if installed (instant)
```bash
bash /mnt/skills/user/exploring-data/scripts/check_install.sh
```
Returns: `installed` or `not_installed`
### 2. Install if needed (one-time, ~19s)
```bash
if [ "$(bash /mnt/skills/user/exploring-data/scripts/check_install.sh)" = "not_installed" ]; then
bash /mnt/skills/user/exploring-data/scripts/install_ydata.sh
fi
```
### 3. Run analysis (always generates JSON + HTML by default)
```bash
bash /mnt/skills/user/exploring-data/scripts/analyze.sh <filepath> [minimal|full] [html|json]
```
**Defaults:** minimal + html (also generates JSON)
**Output:**
- `eda_report.html` - Interactive report for user

How to install
mdr add oaustegard/claude-skills/exploring-data@sha256:e348fff5d5974326The line at the top of this page pins the label v0.2.1, 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.
