What session_start does on Claude Session Continuity

AI agents call session_start to retrieve information from Claude Session Continuity without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why session_start needs a policy

The tool loads/retrieves existing project context at session start. It is described as returning project data, which is a read operation with no apparent side effects. It may write a session record internally, but the primary described function is fetching context. Severity is low as misuse would at most expose project context information.
