What is LLMs.txt?

LLMs.txt works like a concise guide for AI assistants, providing them with structured information about how to interpret and navigate documentation effectively.

When an LLM such as ChatGPT, Claude, or other AI assistants encounters a website or is directed to your documentation, it follows a systematic process to understand the content structure. If the AI tool supports the standard, it first checks for a file called llms.txt in the site's root directory, similar to how search engines check for robots.txt files.

The process begins with discovery, where the AI tool crawls or is directed to your documentation site. During lookup, the system searches for a llms.txt file at the root (for example, docs.telemetryos.com/llms.txt). The parsing phase follows, where the LLM reads structured metadata about the documentation, including the organization of guides, API references, terminology, versioning, and naming conventions.

Through context injection, the model incorporates this metadata when forming answers, effectively mapping questions to the appropriate sections of the documentation. Finally, output refinement occurs, where the model uses the file's instructions to provide more accurate responses. With proper guidance from the llms.txt file, the model becomes significantly less likely to use outdated terminology, reference deprecated endpoints, or miss important context from specific sections of your documentation.

Effectively, llms.txt serves as a comprehensive guidebook that tells AI systems: "Here's how to interpret and navigate our documentation so you answer questions the same way we would." The file doesn't store the actual documentation content but instead points the LLM to the correct locations and explains the structure, ensuring its answers align with the most current information available.

How TelemetryOS uses LLMs.txt

TelemetryOS leverages LLMs.txt to help assistants like ChatGPT or Claude understand and accurately represent its documentation ecosystem. The system implements this through a configuration file positioned at the site root that comprehensively describes the documentation structure, terminology standards, versioning information, and key concepts.

AI tools that support the LLMs.txt standard read this configuration file before answering user questions, significantly reducing information drift and ensuring that responses accurately reflect the latest documentation updates. This approach creates a more reliable bridge between AI assistants and the official TelemetryOS documentation.

Use cases

LLMs.txt addresses the critical need for accurate, up-to-date information delivery when developers rely on AI assistants instead of directly consulting documentation. The system ensures that AI tools provide correct answers about API documentation and maintains consistency across various interaction channels.

The implementation proves particularly valuable for API teams who need AI systems to consistently use correct terminology while avoiding outdated references. Organizations that frequently update API endpoints, parameters, or structural elements benefit from the automated guidance system that keeps AI responses current with the latest changes. The approach significantly reduces the risk of misinformation when developers turn to AI assistants as quick reference tools, while simultaneously maintaining consistency and accuracy across various channels where the API is discussed or referenced.

LLMs.txt does not expose private content. It provides guidance so assistants navigate and reference the docs correctly.
