# self-hosting-devtool (application type)

The **self-hosting-devtool** type marks a development tool whose OWN
development runs through the tool itself — the dogfood loop is constitutive
(the tool's records, gates, and detectors govern the tool's repo), not an
occasional exercise. The compilers-that-compile-themselves shape, one level up.
