Reference

The PSI tools share package refs and service-shaped resources, but each project owns a narrow public boundary.

Psi Surfaces

Surface	Owns	Use For
PsiCLI	Local command line	psi init, psi inspect, and psi launch for users and scripts.
PsiHub	Python package hub	Metadata, validation, local publish/download, cards, config templates, and local hub APIs.
LLLM	Low-Level Language Models	Tactic protocol, service adapters, runtimes, remote clients, and PsiHub metadata helpers.
SSSN	Simple System of Systems Network	Channel, event, artifact, snapshot, store, server, client, and resolver APIs.
AAAX	Advanced Autonomous Agent Executor	Strategy composition, mounted resources, package serving, shell endpoints, and handoff surfaces.

Naming

The docs switch and side drawer use short labels: Psi, LLLM, SSSN, and AAAX. The full names are kept in page content, READMEs, and explanatory text where they can be read without making the navigation too wide.
