AgentTakt: Instructions file for Codex

AGENTS.md

AgentTakt AGENTS.md is an instructions file for Codex, OpenCode from ryoohshima/AgentTakt. It costs 1,374 tokens per session, scanned A, a copy of AgentTakt CLAUDE.md, MIT.

Repository instructions for the AgentTakt project. They describe its Python stack, terminal interface, MCP server, data models, directory layout, and testing setup.

In plain words
What is it for?
Use them when developing or reviewing AgentTakt, a tool that lets people inspect and approve agent task plans in a terminal-based visual editor.
Why use it?
They give coding agents the project context needed to change the right files and follow the repository's conventions.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md; mentions Codex.

This is ryoohshima/AgentTakt's own configuration. It tells Codex and OpenCode how to work on AgentTakt itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything AgentTakt configures →

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

AgentTakt AGENTS.md 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.

Origin

This is a copy

91% identical to AgentTakt CLAUDE.md — 8 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

プロジェクト固有の Codex 指示

このファイルは本プロジェクトに固有のルール・コンテキストを Codex に伝えるためのものでござる。 全プロジェクト共通のガイドラインは ~/.Codex/AGENTS.md に記載されており、本ファイルはそれを補完する形で記述するでござる。

プロジェクト概要

AgentTakt — AI エージェント(Executor)が MCP 経由で送信したタスク実行計画 JSON を、人間がターミナル上の ComfyUI 風ビジュアルノードエディタでレビュー・編集・承認する MCP サーバー兼 TUI ツール。

  • MCP サーバー(agenttakt serve)と TUI 常駐プロセス(agenttakt)の 2 プロセス構成。Unix domain socket(NDJSON)で接続する(詳細は docs/architecture.md)
  • 親 issue: #3(M0〜M4 + docs の sub-issue で進捗管理)

技術スタック

  • 言語: Python 3.10+(開発環境は 3.12)
  • TUI: Textual >= 8.2
  • MCP: Python MCP SDK v1 FastMCP(mcp>=1.9,<2 にピン留め。SDK import は src/agenttakt/server/mcp_server.py に閉じ込める)
  • データモデル: pydantic v2
  • パッケージマネージャ: uv(build backend は hatchling、src レイアウト)

ドッグフーディング(AgentTakt 自身を使う)

本リポジトリは .mcp.json で開発版の AgentTakt(uv run agenttakt serve)を MCP サーバーとして登録している。自分の道具は自分で使うこと。

  • 3 ステップ以上の作業計画を立てたら、着手前に show_plan(plan, summary) でノードグラフとして提示する(プランモードに限らない)
  • 不可逆な作業(リリース・スキーマ変更・広範なリファクタ)は request_approval(plan, summary) で承認を得てから着手する
  • plan JSON の形式は docs/schema.md を参照
  • TUI が起動していないとツールはエラーを返す。その場合は別ターミナルで uv run agenttakt を起動するようユーザーに依頼する(勝手に起動しない)
  • 使いにくさ・表示の不備に気づいたら issue に残す(ドッグフーディングは実運用検証を兼ねる)

What this file has done since we first saw it

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.
