Inspector

The inspector is Dataface's profiling and schema-context system. It profiles tables, caches the results in target/super_schema.json, and reuses that artifact across the CLI, inspect dashboards, the MCP schema tool, and AI prompts. Internally, that artifact is the shared Super Schema that inspect helps build.

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.
