Install with the CLI
In a terminal, from the folder you want:
npx --yes palatekit@latest install guidance-constrained-llm-outputWith no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.
First time: connect the CLI with
npx --yes palatekit@latest loginThe agent writes Guidance programs that enforce a syntax with regex or grammar, guarantee valid JSON, XML or code, and chain several steps in Python. It connects the chosen model: OpenAI, Transformers, llama.cpp or Claude. You get outputs that always follow the requested format.
