This Skill helps developers ensure that large language model outputs conform to strict formats by applying regex checks and formal grammars, preventing malformed or ambiguous results from entering downstream systems.
Install the Guidance package, define a constraint (regex or grammar), and generate a constrained output with a single prompt. Example commands:

To constrain LLM outputs with regex, you can define a pattern like an email or date format and apply it during generation. This Skill enforces regex constraints to ensure the generated text strictly matches your predefined pattern.
You can force an LLM to generate valid JSON by applying grammar-based constraints. This Skill uses formal grammars to produce structured outputs like JSON or XML, ensuring deterministic results for API payloads and data pipelines.
Yes, constrained generation works with OpenAI and Anthropic API backends. This Skill supports applying regex and grammar constraints to models accessed via these APIs, as well as local model transforms.
Token healing automatically corrects token boundaries during generation to prevent malformed text. This Skill performs token healing and validates outputs against strict formats before emitting them for downstream workflows.
To extract structured data from unstructured text, you apply grammar or regex constraints to the generation process. This Skill enforces strict output formats, allowing you to reliably extract data that adheres to a predefined schema.
Yes, you can build multi-step workflows with deterministic output formats using Pythonic control flow. This Skill allows you to construct complex pipelines that validate formats and emit strictly formatted outputs at each step.
