Session expert management system for Claude Code projects. Enables tracking, routing, activating, and registering conversation sessions as domain experts. Use this skill when:
(1) Setting up session management for a new project (initialization)
(2) A user requests a feature change, bug fix, or optimization and you need to check if a session expert already handles that domain (routing)
(3) A session has accumulated deep domain context and should register itself as an expert (registration)
(4) A session is expired and needs to be activated for resuming (activation)
(5) The user asks about managing, organizing, or optimizing session documentation
