agent_skills: Jane Street's agent skills, open sourced
Jane Street open-sources its collection of agent skills, starting with a Socratic tutor that turns an LLM into a strict personal teacher.
Why it matters
A rare look at how a famously rigorous engineering shop instructs its agents: reusable SKILL.md packs that any coding agent or chatbot can adopt, starting with a Socratic tutor with diagnostics, skill maps, and spaced review.
What you could build with it
A solo developer could drop the Socratic tutor skill into a coding agent and use it to learn a new framework by building a small project, getting one question at a time instead of finished code dumps.
Does it hold up?
Too early to judge: a week old with 2,227 stars, but only one skill ships so far; the Socratic tutor works by copying a directory or pasting the SKILL.md into a chat.
