Inth founder Christopher Burns explains how C15T became increasingly discoverable through recommendations from Claude, ChatGPT, Codex and Gemini. He treats agent discovery as a developer-experience problem built from several small, measurable improvements rather than a single optimization trick.
Burns recommends a concise hand-written llms.txt, a fuller documentation index and Markdown versions of individual pages. He also describes content negotiation and agent-friendly URL parameters that let tools retrieve lower-cost Markdown instead of parsing full HTML.
For software libraries, Burns argues that coding agents often inspect repositories and installed packages instead of visiting documentation sites. C15T therefore bundles current Markdown and an agents.md guide inside its package, helping agents find authoritative local instructions while reducing search and token overhead.
