misata: Misata is a synthetic data generation tool that works by letting you declare the desired outcomes and then generates realistic, relational data that provably matches those targets. Unlike most tools that learn from existing datasets, Misata can generate data from scratch based on plain English, YAML schemas, or existing database schemas, ensuring referential integrity and statistical accuracy.; thunderbit-mcp-server: Thunderbit MCP Server is an open-source toolkit for the Thunderbit Open API that ships three packages: a CLI for scripted extraction, an MCP server exposing seven scraping and distillation tools, and a Claude Code plugin. It converts any web page to clean LLM-ready Markdown, extracts structured data via JSON Schema, and supports batch processing — all backed by a free API key.
Known-answer testing: Declare the KPI, generate the data, then assert your dbt, Spark, or SQL transform returns exactly that number, providing a ground truth for pipeline tests.
