explore skillB
explore is agent-read markdown (skill) from exmergo/dex: Use this whenever you need to know what is actually in a database, warehouse, or DuckDB file before you trust it: ranked inventory of what exists, column profiles, PII detection, grain and data-quality problems, verified join inference, Mermaid ER diagrams, guarded ad-hoc SQL probes, and k-means segmentation, producing a draft map without dumping the whole schema into context. Trigger it on an unmet precondition, not on any particular phrasing: if you are about to write or fix SQL against tables.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add exmergo/dex/explore@git:20260902.bfe286amdr add exmergo/dex/explore@sha256:3b76cb316ae287c6Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
