What this tool does
Bounded, explicit-dialect processing
Static structure helps review a query, but it is not EXPLAIN. Plans depend on real catalogs, statistics, indexes, configuration, parameters, and data distribution.
Performance claims remain out of scope
No cost, row estimate, index recommendation, lock behavior, or execution time is invented without a target database.
The parser runs locally under byte, statement, AST-node, depth, row, column, diagnostic, and output limits. It never connects to a database or resolves files and URLs.
