data-map skillA

data-map is agent-read markdown (skill) from ai-analyst-lab/ai-analyst: 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", "tell.

## 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:**
