# @agentxm/extension-model

The shared AgentXM extension model: extension identities, handles, fully
qualified names, extension types, manifests, version constraints, package
identities, and the coding-agent capability catalog.

This package is the cross-repository shared kernel between the public AXM
client and the AgentXM platform. Every export lives under an explicit
`./unstable/*` subpath: the surface is unsupported and may change in any
release. Ordinary users should use the [`axm` CLI](https://axm.sh) instead.

The executable-specification metadata contract that used to ship as
`./unstable/specifications` now lives in `@agentxm/specification-metadata`.
