agentic-os

agentic-os is a skill for Claude Code, Codex from mturac/everything-openai-codex. It costs 94 tokens per session (4,573 once invoked), scanned A, original, MIT.

A design for running persistent specialist agents, commands, scripts, and file-based memory inside Codex. It keeps the setup in project files so it can continue across sessions.

In plain words
What is it for?
Use it to build a personal agent system, route work to specialist agents, add slash commands, schedule scripts, and keep project decisions or logs between sessions.
Why use it?
It gives long-running or repeated agent work a stable structure and a place to store state without an external database.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill accesses MCP server configuration files (mcp.json). MCP configs contain server URLs, authentication tokens, and tool definitions — reading them allows the skill to discover and potentially abuse other tool integrations.
    Fix: Remove all code or instructions that read MCP configuration files (mcp.json). MCP server details should be managed by the agent runtime, not read by individual skills.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agentic-os scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

エージェニック OS

OpenAI Codex をチャットセッションではなく永続的なランタイム / オペレーティングシステムとして扱います。このスキルは本番のエージェニックセットアップで使用されるアーキテクチャを成文化します:スペシャリストエージェントにタスクをルーティングするカーネル設定、永続的なファイルベースのメモリ、スケジュールされた自動化、JSON/Markdown データ層。

起動タイミング

  • OpenAI Codex 内でマルチエージェントワークフローを構築する
  • セッション再起動後も維持される永続的な OpenAI Codex 自動化をセットアップする
  • 繰り返しタスク向けの「パーソナル OS」または「エージェニック OS」を作成する
  • ユーザーが「エージェニック OS」、「パーソナル OS」、「マルチエージェント」、「エージェントコーディネーター」、「永続エージェント」と言う
  • コンテキストがセッションをまたいで維持される必要がある長期プロジェクトを構造化する

アーキテクチャ概要

エージェニック OS には 4 つの層があります。各層はプロジェクトルートのディレクトリです。

project-root/
├── CODEX.md          # カーネル: アイデンティティ、ルーティングルール、エージェントレジストリ
├── agents/            # スペシャリストエージェント定義(Markdown プロンプト)
├── .codex/commands/  # スラッシュコマンド: ユーザー向け CLI
├── scripts/           # デーモンスクリプト: スケジュールまたはイベント駆動タスク
└── data/              # 状態: JSON/Markdown ファイルシステム、外部 DB なし

層の責任

層 目的 永続化

エージェント(agents/) スコープされたツールとメモリを持つスペシャリストアイデンティティ Git 追跡

カーネル

CODEX.md はカーネルです。COO / オーケストレーターとして機能します。Codex はセッション開始時にそれを読み、作業をルーティングするために使用します。

カーネル構造

# CODEX.md - エージェニック OS カーネル

## アイデンティティ
あなたは [project-name] の COO です。タスクをスペシャリストエージェントにルーティングします。
コードは直接書きません。適切なエージェントに委任し、結果を統合します。

## エージェントレジストリ

| エージェント | ロール | トリガー |
|---|---|---|
| @dev | コード、アーキテクチャ、デバッグ | ユーザーが「build」、「fix」、「refactor」と言う |
| @writer | ドキュメント、コンテンツ、メール | ユーザーが「write」、「draft」、「blog」と言う |
| @researcher | 調査、分析、事実確認 | ユーザーが「research」、「analyze」、「compare」と言う |
| @ops | DevOps、デプロイ、インフラ | ユーザーが「deploy」、「CI」、「server」と言う |

## ルーティングルール
1. ユーザーリクエストのインテントキーワードを解析する
2. エージェントレジストリのトリガー列にマッチさせる
3. `agents/<name>.md` から対応するエージェントファイルをロードする
4. 完全なコンテキストでハンドオフ実行する
5. 結果を統合してユーザーに提示する

## モデルポリシー
- デフォルトモデル: リポジトリまたはハーネスのデフォルトを使用する。
- @dev タスク: 複雑なアーキテクチャには高い推論モデルを優先する。
- @researcher タスク: 設定された調査対応モデルと承認された検索ツールを使用する。
- コストの上限: プロジェクトの設定された支出閾値を超える前に警告する。

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agentic-os is a skill published in the GitHub repository mturac/everything-openai-codex (84 stars, last pushed 2mo ago), licensed MIT. It adds 94 tokens to every session and 4,573 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
