Changelog

A capability id is a contract: once published it is as permanent as a REST path, because an integration, a saved Claude prompt and a Zap all hold it. Nothing here is ever renamed out from under you — a rename goes through a deprecation alias, and the old id keeps resolving on every surface.

Unreleased

Published and callable now; not yet part of a dated release. Everything here is live — the section exists so you can tell what is new since you last read this page.

The capability registry2026-09-01

The spine of the platform program: one typed description per operation, with the REST API, both MCP servers, the Claude connector, this site and the in-app copilot all generated from it.

Deprecated ids

Each of these still resolves, on every surface — this is not a list of breakages, it is the list of names to stop writing.
