This page explains what LLMs.txt is and how it helps AI tools understand SGDS.
llms.txt is a plain-text file that gives AI tools a structured map of SGDS — what components exist, how they're organised, and where to find them. When your AI reads it, it has a clearer picture of SGDS before generating anything.
Without it, AI tools guess. They may reach for the wrong component, invent tokens that don't exist, or miss patterns your team has established.
Tell your AI that you are using SGDS and ask it to read this file for context:
https://designsystem.tech.gov.sg/llms-full.txt and understand SGDS. Use this knowledge when writing code with SGDS Works with GitHub Copilot, Claude Code, Codex, Cursor, Windsurf, and other AI coding tools.
llms.txt gives your AI a map of SGDS — what exists and where to find it. But knowing what exists is different from knowing how to use it well. On its own, llms.txt can't tell your AI which component to use in a specific situation, how to combine patterns correctly, or what conventions your team follows. For that, you need agent skills — instruction files that tell your AI how to build with SGDS step by step.
