About

What this is

A reference to the protocols and practices AI agents are built from. One page per concept. Each page states what the thing is, how it works, when to use it, what changed recently, and what to watch out for.

How pages are written

• Every page is written by hand by The maintainer, from the primary source: the specification, the upstream repository, or the vendor's own announcement.
• Every page lists its sources.
• Every page shows the spec version it was written against and the date it was last reviewed. If the reviewed date is old, treat the page as possibly stale.
• Pages are marked stable, changing or new so you know how much to trust them next month.

Corrections

If something is wrong, suggest a fix. Good corrections land within days and the page's reviewed date is updated.

What this is not

Not a wiki, not a news feed, not vendor-sponsored. No page is longer than it needs to be.
