  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by xu-xiang on GitHub. Read the source before you install it.

Installation

Install the Iterative Retrieval AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/xu-xiang/everything-claude-code-zh.git /tmp/everything-claude-code-zh
mkdir -p .claude/skills
cp -r /tmp/everything-claude-code-zh/docs/ja-JP/skills/iterative-retrieval .claude/skills/iterative-retrieval
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Iterative Retrieval in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Iterative Retrieval on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Iterative Retrieval is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

反复检索模式 (Iterative Retrieval Pattern)

解决多智能体工作流(Multi-agent Workflow)中的“上下文问题”。子智能体在开始工作之前,通常不知道需要哪些上下文。

问题

子智能体(Sub-agent)在启动时上下文有限。它们通常不知道:

  • 哪些文件包含相关的代码
  • 代码库中存在哪些模式(Patterns)
  • 项目使用什么术语

标准方法往往会失败:

  • 发送全部:超出上下文限制(Context Limit)
  • 什么都不发:智能体缺乏关键信息
  • 猜测所需内容:经常出错

解决方案:反复检索

分为 4 个阶段的循环,逐步优化上下文:

┌─────────────────────────────────────────────┐
│                                             │
│   ┌──────────┐      ┌──────────┐            │
│   │ DISPATCH │─────▶│ EVALUATE │            │
│   └──────────┘      └──────────┘            │
│        ▲                  │                 │
│        │                  ▼                 │
│   ┌──────────┐      ┌──────────┐            │
│   │   LOOP   │◀─────│  REFINE  │            │
│   └──────────┘      └──────────┘            │
│                                             │
│        最大 3 个循环,之后继续执行             │
└─────────────────────────────────────────────┘

阶段 1: 派发 (DISPATCH)

收集候选文件的初始宽泛查询:

javascript
// 从高层意图开始
const initialQuery = {
  patterns: ['src/**/*.ts', 'lib/**/*.ts'],
  keywords: ['authentication', 'user', 'session'],
  excludes: ['*.test.ts', '*.spec.ts']
};

// 派发给检索智能体
const candidates = await retrieveFiles(initialQuery);

阶段 2: 评估 (EVALUATE)

评估获取内容的关联性(Relevance):

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)
  }));
}

评分标准:

  • 高 (0.8-1.0):直接实现目标功能
  • 中 (0.5-0.7):包含相关的模式或类型
  • 低 (0.2-0.4):间接相关
  • 无 (0-0.2):不相关,排除

阶段 3: 优化 (REFINE)

根据评估更新检索标准:

javascript
function refineQuery(evaluation, previousQuery) {
  return {
    // 添加在高关联性文件中发现的新模式
    patterns: [...previousQuery.patterns, ...extractPatterns(evaluation)],

    // 添加在代码库中发现的术语
    keywords: [...previousQuery.keywords, ...extractKeywords(evaluation)],

    // 排除已确认的无关路径
    excludes: [...previousQuery.excludes, ...evaluation
      .filter(e => e.relevance < 0.2)
      .map(e => e.path)
    ],

    // 针对特定的缺口 (Gaps)
    focusAreas: evaluation
      .flatMap(e => e.missingContext)
      .filter(unique)
  };
}

阶段 4: 循环 (LOOP)

使用优化后的标准重复执行(最多 3 个循环):

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);

    // 检查是否有足够的上下文
    const highRelevance = evaluation.filter(e => e.relevance >= 0.7);
    if (highRelevance.length >= 3 && !hasCriticalGaps(evaluation)) {
      return highRelevance;
    }

    // 优化并继续
    query = refineQuery(evaluation, query);
    bestContext = mergeContext(bestContext, highRelevance);
  }

  return bestContext;
}

实践案例

案例 1:Bug 修复上下文

任务:"修复认证令牌过期 Bug"

循环 1:
  DISPATCH: 在 src/** 中搜索 "token"、"auth"、"expiry"
  EVALUATE: 发现 auth.ts(0.9)、tokens.ts(0.8)、user.ts(0.3)
  REFINE: 添加 "refresh"、"jwt" 关键词;排除 user.ts

循环 2:
  DISPATCH: 使用优化后的术语搜索
  EVALUATE: 发现 session-manager.ts(0.95)、jwt-utils.ts(0.85)
  REFINE: 已获得足够上下文(2 个极高关联性文件)

结果: auth.ts, tokens.ts, session-manager.ts, jwt-utils.ts

案例 2:功能实现

任务:"在 API 端点添加速率限制"

循环 1:
  DISPATCH: 在 routes/** 中搜索 "rate"、"limit"、"api"
  EVALUATE: 未匹配 - 代码库使用的是 "throttle" 术语
  REFINE: 添加 "throttle"、"middleware" 关键词

循环 2:
  DISPATCH: 使用优化后的术语搜索
  EVALUATE: 发现 throttle.ts(0.9)、middleware/index.ts(0.7)
  REFINE: 需要路由器模式(Router Pattern)

循环 3:
  DISPATCH: 搜索 "router"、"express" 模式
  EVALUATE: 发现 router-setup.ts(0.8)
  REFINE: 已获得足够上下文

结果: throttle.ts, middleware/index.ts, router-setup.ts

与智能体集成

在智能体提示词(Prompt)中使用:

markdown
在获取此任务的上下文时:
1. 从宽泛的关键词搜索开始
2. 评估每个文件的关联性(0-1 刻度)
3. 识别仍缺失的上下文
4. 优化检索标准并重复(最多 3 个循环)
5. 返回关联性在 0.7 以上的文件

最佳实践

  1. 宽进严出 - 初始查询不要过于具体。
  2. 学习代码库术语 - 第一个循环通常能揭示项目的命名规范。
  3. 追踪缺失内容 - 明确的缺口(Gaps)识别能有效驱动检索优化。
  4. “足够好”即可停止 - 3 个高关联性文件通常优于 10 个平庸文件。
  5. 果断排除 - 低关联性文件通常不会在后续循环中变得相关。

Frequently asked questions

What does the Iterative Retrieval AI skill do?

为了解决子智能体(Sub-agent)的上下文问题,逐步优化上下文获取的模式

Why use Iterative Retrieval on TypingMind?

Because you install it once and use it with any model. Iterative Retrieval is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Iterative Retrieval in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/xu-xiang/everything-claude-code-zh/tree/main/docs/ja-JP/skills/iterative-retrieval. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Iterative Retrieval?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Iterative Retrieval?

As many as you like. As long as a model supports skills, you can use Iterative Retrieval with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Iterative Retrieval AI skill free?

Yes. It is published on GitHub by xu-xiang under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
