Create a new sncro session. Returns a session key and secret.
Args:
project_key: The project key from CLAUDE.md (registered at sncro.net)
git_user: The current git username (for guest access control). If
omitted or empty, the call is treated as a guest session — allowed
only when the project owner has "Allow guest access" enabled.
brief: If True, skip the first-run briefing (tool list, tips, mobile
notes) and return a compact response. Pass this on the second and
subsequent create_session calls in the same conversation, once
you already know how to use the tools.
After calling this, tell the user to paste the enable_url in their browser.
Then use the returned session_key and session_secret with all other sncro tools.
If no project key is available: tell the user to go to https://www.sncro.net/projects
to register their project and get a key. It takes 30 seconds — sign in with GitHub,
click "+ Add project", enter the domain, and copy the project key into CLAUDE.md.
