baml-codegen

name	baml-codegen
description	Use when generating BAML code for type-safe LLM extraction, classification, RAG, or agent workflows - creates complete .baml files with types, functions, clients, tests, and framework integrations from natural language requirements. Queries official BoundaryML repositories via MCP for real-time patterns. Supports multimodal inputs (images, audio), Python/TypeScript/Ruby/Go, 10+ frameworks, 50-70% token optimization, 95%+ compilation success.
license	Apache-2.0
compatibility	Requires MCP servers: baml_Docs (required), baml_Examples (optional). Works offline with 80% functionality using cached patterns.

BAML Code Generation

Generate type-safe LLM extraction code. Use when creating structured outputs, classification, RAG, or agent workflows.

Golden Rules

• NEVER edit baml_client/ - 100% generated, overwritten on every baml-cli generate; check baml_src/generators.baml for output_type (python, typescript, ruby, go)
• ALWAYS edit baml_src/ - Source of truth for all BAML code
• Run baml-cli generate after changes - Regenerates typed client code for target language

Philosophy (TL;DR)

• Schema Is The Prompt - Define data models first, compiler injects types
• - Use enums/classes/unions, not string parsing
