What problem does it solve? Working on Nodefony's AI agentic layer (Phase 12) without knowing its design invariants, module states, and phase dependencies risks breaking work-in-progress modules or violating frozen architectural decisions. ## Core Features & Use Cases - Phase 12 AI Layer Context: Documents the planned modules (@nodefony/llm, vector, rag, memory, agent, agent-guard) with their sub-phases and real implementation status. - Design Invariants: Enforces seven non-negotiable rules including generic modules, dependency injection, native streaming, human validation, sovereign mode, AI Act compliance, and WebSocket as LLM transport. - Delivered Phase Pointers: Redirects conventions from completed phases (Studio P10, Realtime P13, Vite builder P14) to the skills and docs that now own them. - Use Case: Before designing an interface consumed by an AI agent, consult this Skill to apply the invariants and respect the rule against starting AI module sessions before Phase 6 completes. ## Quick Start Ask the agent to review the design invariants and module status before starting work on any @nodefony AI module or admin API convention.
