// why it matters
AI agents don't read docs. They read specs.
Specification work. Editors and working groups keep each spec precise, interoperable and ready for what comes next.
Tooling and test suites. Reference implementations, validators and compliance tests are what the whole ecosystem builds on.
Community. Documentation, mentorship and events bring new contributors in and keep the standards open to everyone.
Four specs. One ecosystem.
Pick the standards your business depends on and help fund them.
