The Pre-Agent Ontology Skill provides a rigorous mathematical foundation for building emergent AI agent systems. Instead of treating agents as primitives, this skill implements a five-layer hierarchy—ranging from pre-ontological seeds to emergent fiber bundles—ensuring system stability through trifurcation patterns and GF(3) conservation. It is ideal for developers building complex, deterministic agentic architectures that require formal verification, sheaf-theoretic gluing, and order-independent execution within the Claude Code environment.
