What it does

Autonomous Agent Harness is an agent skill from affaan-m/ECC. Claude Codeを永続的なメモリ、スケジュール済み操作、コンピュータ使用、タスクキューイングを備えた完全自動エージェントシステムに変換します。スタンドアロンエージェントフレームワーク（Hermes、AutoGPT）を、Claude Codeのネイティブcrons、dispatch、MCPツール、メモリを活用して置き換えます。ユーザーが継続的な自動操作、スケジュール済みタスク、または自己指令エージェントループを望む場合に使用します。

Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Scheduled and recurring tasks and Autonomous loops. It works with Model Context Protocol. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.

Workflow steps

2 steps, taken from the step headings in SKILL.md.

永続的なメモリ
スケジュール済み操作（Crons）

What it can do on your machine

Read from SKILL.md and the folder at commit 4eb71d9. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Autonomous Agent Harness loads about 859 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 37 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~61
When it runs · the whole SKILL.md, loaded when a task matches: ~859

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

自動エージェントハーネス

ネイティブ機能とMCPサーバーのみを使用して、Claude Codeを永続的な自己指令エージェントシステムに変換します。

同意とセーフティバウンダリ

自動操作は、ユーザーによって明示的に要求され、スコープが設定される必要があります。スケジュール、リモートエージェントの派遣、永続的なメモリの書き込み、コンピュータ制御の使用、外部への投稿、サードパーティリソースの変更、または現在のセットアップのプライベート通信に対する行動を行わないでください。ユーザーがその機能と対象ワークスペースを承認していない限り。

クレデンシャル、プライベートワークスペースのエクスポート、個人データセット、およびアカウント固有の自動化を再利用可能なECCアーティファクトから除外する前に、ドライラン計画とローカルキューファイルを好みます。

アクティベーション時期

ユーザーが継続的に実行されるか、スケジュール上で実行されるエージェントを望む
定期的にトリガーされる自動化ワークフローを設定
セッション全体でコンテキストを記憶する個人的なAIアシスタントを構築
ユーザーが「これを毎日実行」、「これを定期的にチェック」、「監視を続ける」と言う

コアコンポーネント

1. 永続的なメモリ

構造化データ用のMCPメモリサーバーで拡張されたClaude Codeの組み込みメモリシステムを使用します。

組み込みメモリ (~/.claude/projects/*/memory/):

ユーザーの設定、フィードバック、プロジェクトコンテキスト
フロントマター付きのマークダウンファイルとして保存
セッション開始時に自動的に読み込まれる

MCPメモリサーバー (構造化知識グラフ):

エンティティ、関係、観察
クエリ可能なグラフ構造
クロスセッション永続性

メモリパターン：

# 短期：現在のセッションコンテキスト
TodoWriteをセッション内タスク追跡に使用

# 中期：プロジェクトメモリファイル
クロスセッションリコールの場合は～/.claude/projects/*/memory/に書き込む

# 長期：MCPナレッジグラフ
mcp__memory__create_entitiesを永続的な構造化データに使用
mcp__memory__create_relationsを関係マッピングに使用
mcp__memory__add_observationsを既知のエンティティについての新しい事実に使用

2. スケジュール済み操作（Crons）

Claude Codeのスケジュール済みタスクを使用して、定期的なエージェント操作を作成します。

cronを設定する：

# MCPツール経由
mcp__scheduled-tasks__create_scheduled_task({
  name: "daily-pr-review",
  schedule: "0 9 * * 1-5",  # 平日午前9時
  prompt: "affaan-m/ECCのすべてのオープンPRを確認します。各について：CIステータスをチェック、変更を確認、問題にフラグを立てます。メモリに概要を投稿します。",
  project_dir: "/path/to/repo"
})

完全な設定例

セッション全体でコンテキストを記憶し、複数の定期的なタスクを実行する完全に自動化されたエージェントの設定については、高度な設定セクションを参照してください。

Questions about Autonomous Agent Harness

What does Autonomous Agent Harness do?

When should I use Autonomous Agent Harness?

Autonomous Agent Harness fits situations like: tasks that involve Scheduled and recurring tasks; tasks that involve Autonomous loops.

How do I install Autonomous Agent Harness in Claude Code?

Run `npx skills add affaan-m/ECC --skill autonomous-agent-harness -a claude-code`. Or copy the skill folder (docs/ja-JP/skills/autonomous-agent-harness in affaan-m/ECC) into .claude/skills/autonomous-agent-harness in your project. Claude Code loads it when a task matches its description.

How do I install Autonomous Agent Harness in Codex?

Run `npx skills add affaan-m/ECC --skill autonomous-agent-harness -a codex`. Or copy the skill folder (docs/ja-JP/skills/autonomous-agent-harness in affaan-m/ECC) into .agents/skills/autonomous-agent-harness in your project. Codex loads it when a task matches its description.

Can I use Autonomous Agent Harness in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add affaan-m/ECC --skill autonomous-agent-harness -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/autonomous-agent-harness, .gemini/skills/autonomous-agent-harness, .github/skills/autonomous-agent-harness and .opencode/skills/autonomous-agent-harness in your project.

What does Autonomous Agent Harness need to run?

SKILL.md names no scripts, command-line tools or credentials: Autonomous Agent Harness is instructions for the agent only.

Does Autonomous Agent Harness access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Autonomous Agent Harness safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Autonomous Agent Harness use?

Autonomous Agent Harness is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Autonomous Agent Harness use?

About 859 tokens (SKILL.md is roughly 3.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Autonomous Agent Harness?

Skills that share tags, products or a category with Autonomous Agent Harness: Toolify (coreyhaines31/makerskills, 851 stars), agtx One-Shot Project Runner (fynnfluegge/agtx, 1.7k stars), Harness 24h (thu-nmrc/OpenHarness, 118 stars) and Recurring Prompt Loop (QwenLM/qwen-code, 28k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Autonomous Agent Harness?

affaan-m (a GitHub user) maintains it in affaan-m/ECC, which has 276,111 GitHub stars. The repository holds 683 skills in this directory. The repository was last updated on October 10, 2026.

Source: affaan-m/ECC on GitHub. Facts on this page come from the repository at the commit we read; the author's words are quoted as theirs.
