The Feynman technique works by explaining a concept in simple language, then identifying what you cannot explain clearly. This Skill automates that loop: it explains one core idea, asks you to explain it back, grades your attempt, and re-teaches only the gaps until you pass.

It silently checks five criteria: accuracy, completeness, whether you explain the mechanism rather than just the facts, jargon used without unpacking, and whether your analogy actually holds. It then names what landed and up to three concrete gaps.

Broad topics like calculus are narrowed first by asking which subtopic to start with, such as derivatives, integrals, or limits. Each loop covers one core idea in roughly 150-250 words rather than the whole subject at once.

After two retries on the same gap, the Skill switches to an entirely different analogy instead of repeating the same explanation. It never dumps the full answer and never accepts a vague claim of understanding without a re-explanation.

It is designed for conceptual understanding, not for quick factual lookups or reference-style answers. If you only need a definition or a code snippet, a direct answer is faster than an interactive teaching loop.
