What

Adds shadow-tutor under skills/.curated/shadow-tutor/ — a post-session programming tutor.

After an AI-assisted coding session, it produces a short, evidence-backed review of why the agent made each decision (including the options it rejected), every point bound to the session's real diffs, then walks the user through forced-recall exercises graded against the project's own tests. It runs in-session on the user's existing model (no API key), and is format-identical for Codex and Claude Code.

Why

AI coding agents make it easy to ship code you don't understand — learning lives in the struggle the agent removes. This skill re-inserts that cognitive friction after the work, so developers actually learn instead of just shipping. It's built with Codex's own skills paradigm.

Contents

Self-contained skill directory:

  • SKILL.md — routing metadata + entry instructions
  • METHODOLOGY.md — the teaching methodology (evidence-first selection, why-over-what, graded exercises, structured closeout)
  • scripts/knowledge.mjs — per-user knowledge profile (schema-validated, atomic writes)
  • LICENSE.txt — MIT

Notes

  • Source repo with an eval harness (rubric-scored teaching quality; seed fixture scores 15/16), tests, and CI: https://github.com/lzfxxx/shadow-tutor
  • I placed it in .curated/; happy to move it if there's a preferred location/process for community submissions.

teaches why each decision was made (including rejected options), bound to the
session's real diffs, then drills the user with test-graded forced-recall
exercises. Self-contained (SKILL.md + METHODOLOGY.md + scripts/), MIT licensed.
