What it does

Iterative Retrieval is an agent skill from affaan-m/ECC. サブエージェントのコンテキスト問題を解決するために、コンテキスト取得を段階的に洗練するパターン

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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.

Example prompts

  • “/iterative-retrieval”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. 広く開始し、段階的に絞る - 初期クエリで過度に指定しない
  2. コードベースの用語を学ぶ - 最初のサイクルでしばしば命名規則が明らかになる
  3. 不足しているものを追跡 - 明示的なギャップ識別が洗練を促進
  4. 「十分に良い」で停止 - 3つの高関連性ファイルは10個の平凡なファイルより優れている
  5. 確信を持って除外 - 低関連性ファイルは関連性を持つようにならない

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 (its code samples are javascript and markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • x.com

    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

Iterative Retrieval loads about 1.1k tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 69 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~17
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

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.

サブエージェントのコンテキスト問題を解決するために、コンテキスト取得を段階的に洗練するパターン

反復検索パターン

マルチエージェントワークフローにおける「コンテキスト問題」を解決します。サブエージェントは作業を開始するまで、どのコンテキストが必要かわかりません。

問題

サブエージェントは限定的なコンテキストで起動されます。以下を知りません:

  • どのファイルに関連するコードが含まれているか
  • コードベースにどのようなパターンが存在するか
  • プロジェクトがどのような用語を使用しているか

標準的なアプローチは失敗します:

  • すべてを送信: コンテキスト制限を超える
  • 何も送信しない: エージェントに重要な情報が不足
  • 必要なものを推測: しばしば間違い

解決策: 反復検索

コンテキストを段階的に洗練する4フェーズのループ:

┌─────────────────────────────────────────────┐
│                                             │
│   ┌──────────┐      ┌──────────┐            │
│   │ DISPATCH │─────│ EVALUATE │            │
│   └──────────┘      └──────────┘            │
│        ▲                  │                 │
│        │                  ▼                 │
│   ┌──────────┐      ┌──────────┐            │
│   │   LOOP   │─────│  REFINE  │            │
│   └──────────┘      └──────────┘            │
│                                             │
│        最大3サイクル、その後続行              │
└─────────────────────────────────────────────┘
フェーズ1: DISPATCH

候補ファイルを収集する初期の広範なクエリ:

javascript
// 高レベルの意図から開始
const initialQuery = {
  patterns: ['src/**/*.ts', 'lib/**/*.ts'],
  keywords: ['authentication', 'user', 'session'],
  excludes: ['*.test.ts', '*.spec.ts']
};

// 検索エージェントにディスパッチ
const candidates = await retrieveFiles(initialQuery);
フェーズ2: EVALUATE

取得したコンテンツの関連性を評価:

javascript
function evaluateRelevance(files, task) {
  return files.map(file => ({
    path: file.path,
    relevance: scoreRelevance(file.content, task),
    reason: explainRelevance(file.content, task),
    missingContext: identifyGaps(file.content, task)
  }));
}

スコアリング基準:

  • 高(0.8-1.0): ターゲット機能を直接実装
  • 中(0.5-0.7): 関連するパターンや型を含む
  • 低(0.2-0.4): 間接的に関連
  • なし(0-0.2): 関連なし、除外
フェーズ3: REFINE

評価に基づいて検索基準を更新:

javascript
function refineQuery(evaluation, previousQuery) {
  return {
    // 高関連性ファイルで発見された新しいパターンを追加
    patterns: [...previousQuery.patterns, ...extractPatterns(evaluation)],

    // コードベースで見つかった用語を追加
    keywords: [...previousQuery.keywords, ...extractKeywords(evaluation)],

    // 確認された無関係なパスを除外
    excludes: [...previousQuery.excludes, ...evaluation
      .filter(e => e.relevance < 0.2)
      .map(e => e.path)
    ],

    // 特定のギャップをターゲット
    focusAreas: evaluation
      .flatMap(e => e.missingContext)
      .filter(unique)
  };
}
フェーズ4: LOOP

洗練された基準で繰り返す(最大3サイクル):

javascript
async function iterativeRetrieve(task, maxCycles = 3) {
  let query = createInitialQuery(task);
  let bestContext = [];

  for (let cycle = 0; cycle < maxCycles; cycle++) {
    const candidates = await retrieveFiles(query);
    const evaluation = evaluateRelevance(candidates, task);

    // 十分なコンテキストがあるか確認
    const highRelevance = evaluation.filter(e => e.relevance >= 0.7);
    if (highRelevance.length >= 3 && !hasCriticalGaps(evaluation)) {
      return highRelevance;
    }

    // 洗練して続行
    query = refineQuery(evaluation, query);
    bestContext = mergeContext(bestContext, highRelevance);
  }

  return bestContext;
}

実践例

例1: バグ修正コンテキスト
タスク: "認証トークン期限切れバグを修正"

サイクル1:
  DISPATCH: src/**で"token"、"auth"、"expiry"を検索
  EVALUATE: auth.ts(0.9)、tokens.ts(0.8)、user.ts(0.3)を発見
  REFINE: "refresh"、"jwt"キーワードを追加; user.tsを除外

サイクル2:
  DISPATCH: 洗練された用語で検索
  EVALUATE: session-manager.ts(0.95)、jwt-utils.ts(0.85)を発見
  REFINE: 十分なコンテキスト(2つの高関連性ファイル)

結果: auth.ts、tokens.ts、session-manager.ts、jwt-utils.ts
例2: 機能実装
タスク: "APIエンドポイントにレート制限を追加"

サイクル1:
  DISPATCH: routes/**で"rate"、"limit"、"api"を検索
  EVALUATE: マッチなし - コードベースは"throttle"用語を使用
  REFINE: "throttle"、"middleware"キーワードを追加

サイクル2:
  DISPATCH: 洗練された用語で検索
  EVALUATE: throttle.ts(0.9)、middleware/index.ts(0.7)を発見
  REFINE: ルーターパターンが必要

サイクル3:
  DISPATCH: "router"、"express"パターンを検索
  EVALUATE: router-setup.ts(0.8)を発見
  REFINE: 十分なコンテキスト

結果: throttle.ts、middleware/index.ts、router-setup.ts

エージェントとの統合

エージェントプロンプトで使用:

markdown
このタスクのコンテキストを取得する際:
1. 広範なキーワード検索から開始
2. 各ファイルの関連性を評価(0-1スケール)
3. まだ不足しているコンテキストを特定
4. 検索基準を洗練して繰り返す(最大3サイクル)
5. 関連性が0.7以上のファイルを返す

ベストプラクティス

  1. 広く開始し、段階的に絞る - 初期クエリで過度に指定しない
  2. コードベースの用語を学ぶ - 最初のサイクルでしばしば命名規則が明らかになる
  3. 不足しているものを追跡 - 明示的なギャップ識別が洗練を促進
  4. 「十分に良い」で停止 - 3つの高関連性ファイルは10個の平凡なファイルより優れている
  5. 確信を持って除外 - 低関連性ファイルは関連性を持つようにならない

Can I use Iterative Retrieval 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 iterative-retrieval -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/iterative-retrieval, .gemini/skills/iterative-retrieval, .github/skills/iterative-retrieval and .opencode/skills/iterative-retrieval in your project.

What does Iterative Retrieval need to run?

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

Does Iterative Retrieval access the network?

SKILL.md names 1 domain. As links in the text: x.com. This is read from the text; nothing was executed.

Is Iterative Retrieval 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 Iterative Retrieval use?

Iterative Retrieval 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 Iterative Retrieval use?

About 1.1k tokens (SKILL.md is roughly 4.5k 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 Iterative Retrieval?

Skills that share tags, products or a category with Iterative Retrieval: Iterative Retrieval (xu-xiang/everything-claude-code-zh, 2k stars), Iterative Retrieval (closedloop-ai/claude-plugins, 122 stars), Iterative Retrieval (kubefleet-dev/kubefleet, 162 stars) and Retrieval Reflex (garrytan/gbrain, 31k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
