What problem does it solve?

This Skill addresses the challenge of generating structured and predictable output from Large Language Models (LLMs) by enforcing grammar constraints. It ensures that LLM outputs conform to specific formats, types, and rules, making them more reliable for programmatic use.

Core Features & Use Cases

• Grammar-Constrained Generation: Use regular or context-free grammars to guide LLM output.
• Structured Outputs: Generate outputs that are guaranteed to be in a specific format (e.g., JSON, specific text patterns).
• Type-Safe Prompting: Build complex generation pipelines with interleaved computation and constrained generation.
• Use Case: Automatically generate valid JSON objects from an LLM for API requests, ensuring the output is always parsable and adheres to a predefined schema.

Quick Start

Use the guidance-grammars skill to generate a JSON object representing a user profile with name and email fields.
