What

A self-hosted runner is a copy of Claude Code that you run on your own machine to carry out sessions, where a session is one continuous piece of work with Claude. The runner now reads a set of startup command phases from its configuration a single time and passes them to the first session it starts. Later sessions do not receive them again.

Why

This is internal to the runner. In practice, any startup command phases apply only to the first session a runner starts.
