Resource submission: llms.txt validator (MIT)

Hi,

I'm writing on behalf of BridgeToAgent editorial — we publish technical
writing about agent-readiness standards (llms.txt, agents.json,
agent-instructions.md, WebMCP) and ship a small kit that generates
those files for site owners.

We just released an open-source llms.txt validator:

Hosted: https://www.bridgetoagent.com/tools/llms-txt-validator
Source: https://github.com/bridgetoagent/llms-txt-validator
npm: https://www.npmjs.com/package/@bridgetoagent-com/llms-txt-validator

It checks parser conformance against the llmstxt.org reference spec,
flags malformed link syntax, checks link reachability on referenced
URLs, and runs both as a hosted web tool and as a CLI / JS API.

MIT-licensed. No signup, no email gate.

If you maintain a resources list of tools that work with llms.txt,
we'd be grateful to be considered. Happy to answer questions or
adjust anything in our implementation if you spot something off-spec.

A few of our recent posts engaging with the spec, for context on
where we're coming from:

- https://www.bridgetoagent.com/blog/llms-txt-vs-robots-txt
- https://www.bridgetoagent.com/blog/free-llms-txt-generators-what-they-dont-tell-you

Thanks for stewarding the spec.

The submission does not identify a repository file, test, or entry point to change. First locate the project's resources or tools list and confirm with maintainers whether this external validator belongs there; done would be a documented listing if the project accepts it.
