From the SKILL.md

# data-master — universal data processing pipeline

Turn **any data** into a **cleaned, audited, Nature-grade report + charts** with one command. The agent reads the data, decides modality, picks methods, runs the pipeline, and writes evidence-backed outputs. The user never has to choose a statistical test or a chart type.

## Contract

Installed CLI: `data-master analyze <file> --out <dir>`; use
`data-master doctor --json` to diagnose the environment and
`data-master verify <dir> --json` to check saved artifact hashes.
`data-master demo --out <new-dir>` runs a synthetic example, and
`data-master skill install` installs this skill atomically from the npm or
Python distribution. Existing
`python scripts/run_pipeline.py` commands below remain supported; installing
the CLI alone does not register the skill until `skill install` is run.

- **Input**: `$ARGUMENTS` = a file, a folder, or a glob. Optional flags:
  - `--report nature` (default) | `standard` | `executive` — report template.
  - `--out <dir>` — overrides the output root.
  - `--answers <file>` — answers `answers.template.json` decisions by id; every id and action is validated, and changing the file invalidates the stale cleaning stages on resume. The file may also carry a `run` block declaring `unit_key` / `group` / `outcomes` / `design` / `journal` / `covariates` (validated against the profile; explicit CLI values always win). A decision may name a single `column` of a multi-column flag.
