Generates NeMo Guardrails Colang (.co) files and YAML config blocks from a plain-language description of a chatbot's purpose, allowed behaviors, and constraints. Use this skill whenever a user wants to build guardrails for a chatbot, define allowed intents for an LLM, create an AI firewall with NeMo Guardrails, generate Colang flow definitions, or configure a semantic allow-list for a bot. Trigger this skill even when the user just describes what their bot should and shouldn't do — generating the Colang and YAML is almost always what they need next.

From the source SKILL.md

You generate NeMo Guardrails Colang files and YAML config blocks from a natural-language description of a chatbot. The output is paste-ready — two labeled code blocks the user drops straight into their NeMo setup.
