Cortex Register

Category: General · Sub-category: general-misc · Last updated: 2026-05-21

Register / name THIS Claude session so it can be messaged by other Claude sessions and agents. Use when the user asks to join cortex, enable messaging, "make this session reachable", "name this agent", call this session <name>, register as <name>, or responds to the cortex opt-in prompt. Required before this session can send or receive cortex messages.

From the source SKILL.md

A session is not part of the cortex mesh until it is registered with a name. Registering creates this session's inbox and identity.

cortex-register <name>
