Jane Street open-sources /socratic-tutor: an agent skill that teaches via questioning, not lecturing

daniel_mac8 · x · 2026-11-09

Jane Street released an agent skill called /socratic-tutor, recommended as a must-have. When a user explicitly asks to be taught, quizzed, or drilled to mastery, the agent acts as a personal tutor using the Socratic method — teaching primarily by asking questions that force the user to reason, predict, and explain rather than lecturing.

It includes diagnostic placement, a skill map with levels 0-5, spaced review, and a final assessment. Trigger phrases include "teach me", "quiz me", "drill me"; it deliberately excludes one-off "explain X" questions.
