Use this skill when the user wants read-only analysis of a local MR-RATE SQLite database. Use for natural-language SQL questions, helper views, descriptor tables, schema docs, descriptive statistics, cohort counts, pathology prevalence, metadata coverage, co-occurrence summaries, private patient/study record previews, and requests to show the SQL used. Do not use for downloading, importing, refreshing, or building the database; use mrrate-data-curator for that.
