Codex Retrospective

majiayu000/codex-retrospective

Use when you want Codex to review its own recent history (last N days or specific period) and improve its behavior. Produces minimal, high-signal updates to AGENTS.md and tiny reusable skills. The goal is long-term fluency — Codex gradually becomes better at your specific style, constraints, and workflows.

This is a copy. The original lives at majiayu000/spellbook-codex-retrospective.
