Produce a comprehensive cross-table data health map for the active dataset — the full payoff answer to open-ended "tell me about this data" questions. Run all tables, not just one: table inventory with row counts, PK uniqueness, date range per table, date alignment across tables, column completeness, foreign-key join-rate matrix, relationship diagram, and a thread-to-pull opening hypothesis. Use this skill whenever the user asks a **dataset-wide open question** — "tell me about this data…
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
# Skill: Data Map
## Purpose
Answer the broadest possible question — "tell me about this data" — with the broadest substantive answer: cross-table health, relationships, date alignment, and an opening analytical thread. This is first-contact dataset exploration, not a schema dump and not a steering question.
## When to Fire
**Fires on dataset-wide open questions:**
- "tell me about this data / the data / this dataset / the dataset"
- "what's in here / what's in this data / what's in the data"
- "give me an overview / give me the map / map out the data"
- "what do I have / what do we have here"
- "what does this data look like / show me what we've got"
- Any open question that references the dataset as a whole
**Does NOT fire when:**
- The question names a specific table → use `data-quality-check`
- User invoked `/explore` or is mid-exploration within an already-mapped dataset → use `explore`
- User invoked `/data` or `/data {table}` → use `data-inspect` (schema-only)
- User invoked `/run-pipeline` or a specific analysis → run the pipeline
**Fires regardless of:**

How to install
mdr add ai-analyst-lab/ai-analyst/data-map@sha256:41ada7a05bbf2651The line at the top of this page pins the label git:20260902.b370de6, 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.
