Inspector

The inspector is Dataface's profiling and schema-context system. It profiles tables, caches the results in target/inspect.json, and reuses that artifact across the CLI, inspect dashboards, MCP/catalog tools, and AI prompts.

What it gives you

• Table and column statistics such as row counts, null percentages, distinct counts, min/max values, samples, and distributions.
• Semantic classification such as email, currency_amount, country, date, and other meaning-level types.
• Structure hints such as grain, primary date columns, and inferred relationships between tables.
• Reusable cached context so downstream tools do not need to re-profile a table every time.
