Everything PAI is.
Architecture, algorithm, memory, skills, hooks, agents, security. The complete reference for running the Life Operating System.
The three docs that explain the whole system
New to PAI? Read these three in order and you'll know what the Life Operating System is, why it exists, and how its pieces fit together.
How the work actually gets done
The Algorithm runs every task. Memory persists what was learned. Skills compose capabilities. Hooks make it deterministic.
The interfaces you see and hear
Agents are the speakers; Pulse is the dashboard; Notifications surface signal; Observability proves it all worked.
CLI-first by design
Determinism beats prompts. The Tools subsystem documents how PAI puts code in front of LLM calls everywhere it can.
The articulation primitive and the Life-OS frame
The ISA is the universal artifact for "done." The Life-OS schema is how PAI represents you. Read these to understand the conceptual spine.
The pipelines around the core
Arbol routes content through cloud workers. Feed aggregates intelligence sources. Fabric runs prompt patterns. Delegation parallelizes the workload.
Defense baked into the substrate
Security isn't a layer on top — it's a hook pipeline that runs on every tool call. Threat model, prompt-injection defense, and what actually executes.
