From primitives
Layered explanation of any target -- code, reasoning, decisions, concepts. Explains in what/how/why layers, checks understanding, goes deeper on request. Model-invocable primitive that domain skills compose on.

Explain the target in layers: what it does (one sentence), how it works (trace the mechanism — files, lines, data flow, no hand-waving), why it's done this way (reasoning, alternatives, constraints). Drop layers that add nothing.
After explaining, check: "Does that track?" Go deeper if asked. Admit uncertainty. Revise if wrong. Trace to source — abstract explanations are useless.
