Proposal: Add llms.txt / llms-full.txt for Echo v5 documentation

[iharshr]

Problem

AI coding assistants (like Cursor, Copilot, ChatGPT, and Claude) often struggle with Echo v5 because it introduces major breaking changes from v4 (such as echo.Context becoming a struct and the removal of the built-in logger). Without updated context, LLMs frequently hallucinate old v4 syntax.

Proposal

I propose adding an llms.txt and llms-full.txt file to the root of the repository (or the website documentation).

These files follow the emerging standard for serving high-density, markdown-formatted documentation specifically optimized for LLM consumption.

Benefits

• Better AI Code Generation: Developers using AI tools will get accurate Echo v5 code instantly.
• Fewer Repetitive Issues: Reduces GitHub issues caused by users pasting AI-generated v4 code into v5 projects.
• Lightweight: Easy to maintain alongside standard documentation updates.

Would the maintainers be open to a PR implementing this?

how much of these need updating? Are talking about this https://llmstxt.org/ ?

[iharshr]

yes llmstxt.org , some thing like this https://templui.io/llms.txt

+1 on this. llms.txt is becoming a standard for making docs accessible to AI coding assistants. The format is simple, it's just structured markdown that lives at /llms.txt on the docs site.

For Echo specifically, the most useful content would be:

• Quick reference for middleware setup (most common question I see in these discussions)
• Route registration patterns (static, parametric, grouped)
• Error handler configuration
• Binding/validation patterns

The llms.txt spec from llmstxt.org is straightforward. A single file at the root with sections separated by ## headers. No build step needed, just a static file served by the docs site.

If the maintainers are open to it, I'd be happy to help draft the initial llms.txt based on the v5 docs. The existing markdown docs could be condensed into the format without much effort.

allright, @tamish560, we are waiting for the PR :)
