    Runs SQL statements in memory against real PostgreSQL 18 and SQLite 3.49 engines after loading your schema and sample rows, returning each statement's own verdict: errors with line, column, and hints, constraint violations, or the resulting rows. It also compares both dialects to expose portability differences, all with no database server, network, or API key.

    Enables AI agents to attach to an already-running Electron desktop app and inspect both the Node.js main process and Chromium renderer, invoking IPC channels, evaluating renderer scripts, capturing screenshots, and reading diagnostics. It also lets apps expose custom verification oracles so agents can confirm real business effects like database rows, file sidecars, and hash receipts instead of just UI changes.
