Codex Onboarding | Agent Skills Atlas

About this skill

Onboards a non-Claude-Code agent (GitHub Copilot CLI / Cursor / Aider / Codex / Devin) to this repo on session start. Use when this repo will be operated on by a coding agent that does NOT natively read CLAUDE.md. Mirrors what CLAUDE.md provides to Claude Code, but routes through AGENTS.md (which all major 2026 agents read) and surfaces tool-version floors + 2026 H1 failure-mode mitigations.

Quick start

Copy the install prompt. Use the green button above this README.
Send it to your agent. Paste it into your coding agent’s chat and send.
Review the setup. Your agent checks the skill’s instructions, requirements, and installation scope.
