OpenAI Codex — codex CLI / IDE 拡張 / ChatGPT desktop app(公式表記は Codex in the ChatGPT desktop app)/ cloud からなる OpenAI 公式のコーディングエージェント製品。 対象は learn.chatgpt.com/docs の取得日 2026-10-16 時点(URL に版なし。対象モデル世代は GPT-6 系: gpt-6-astra / gpt-6.1-sol / gpt-6-sol / gpt-6-luna)。 CLI・IDE・desktop app・cloud への導入、CLI / IDE / desktop app のコマンドと設定、AGENTS.md/rules/subagents/memories によるエージェント設定、 Fast / Ultrafast mode、config.toml/MCP 設定、approvals・sandbox・GitHub Action・Codex SDK・App Server による自動化、 plugins・Codex skills 作成・scheduled tasks・Browser・Computer Use・web search による拡張、 ワークスペース administration(LLM gateway・service accounts・Agent Security 含む)、 Codex Security による脆弱性スキャン・修復、cloud/local/worktree 環境の切り替えと Record & Replay、 GitHub・GitLab・Linear・Slack との連携・code review をカバーする。

codex mcp-server は削除済みで、App Server(JSON-RPC)が後継。references/security-automation/agents-sdk-mcp-server.md は codex mcp-server 削除と App Server への移行手順をまとめたページ(旧 Agents SDK 連携例はサポート終了)。

本スキルは OpenAI Codex の公式ドキュメントを蒸留したものであり、本リポジトリが対象とする Claude Code の .claude/ 体系とは別物である。AGENTS.md / rules / subagents など用語が重なる箇所があるが、 設定ファイルの形式・置き場所・意味は Claude Code の CLAUDE.md / .claude/rules/ / .claude/agents/ と互換性がない (AGENTS.md・rules・subagents の詳細は references/agent-configuration/README.md の索引から各ページを参照)。
