About this skill

Iterative Retrieval is a skill in affaan-m/ECC (276k stars). Its SKILL.md is about 1.1k tokens, and copies of it appear in 1 other owners' repositories. Licence: MIT.

Workflow steps

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

  1. 先宽泛,后逐步细化 - 不要过度指定初始查询
  2. 学习代码库术语 - 第一轮循环通常能揭示命名约定
  3. 跟踪缺失内容 - 明确识别差距以驱动优化
  4. 在“足够好”时停止 - 3 个高相关性文件胜过 10 个中等相关性文件
  5. 自信地排除 - 低相关性文件不会变得相关

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 11 tokens; SKILL.md has 81 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~11
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.

逐步优化上下文检索以解决子代理上下文问题的模式
origin
ECC

迭代检索模式

解决多智能体工作流中的“上下文问题”,即子智能体在开始工作前不知道需要哪些上下文。

何时激活

  • 当需要生成需要代码库上下文但无法预先预测的子代理时
  • 构建需要逐步完善上下文的多代理工作流时
  • 在代理任务中遇到"上下文过大"或"缺少上下文"的失败时
  • 为代码探索设计类似 RAG 的检索管道时
  • 在代理编排中优化令牌使用时

问题

子智能体被生成时上下文有限。它们不知道:

  • 哪些文件包含相关代码
  • 代码库中存在哪些模式
  • 项目使用什么术语

标准方法会失败:

  • 发送所有内容:超出上下文限制
  • 不发送任何内容:智能体缺乏关键信息
  • 猜测所需内容:经常出错

解决方案:迭代检索

一个逐步优化上下文的 4 阶段循环:

┌─────────────────────────────────────────────┐
│                                             │
│   ┌──────────┐      ┌──────────┐            │
│   │  调度    │─────│  评估    │            │
│   └──────────┘      └──────────┘            │
│        ▲                  │                 │
│        │                  ▼                 │
│   ┌──────────┐      ┌──────────┐            │
│   │  循环    │─────│  优化    │            │
│   └──────────┘      └──────────┘            │
│                                             │
│        最多3次循环,然后继续                 │
└─────────────────────────────────────────────┘
阶段 1:调度

初始的广泛查询以收集候选文件:

javascript
// Start with high-level intent
const initialQuery = {
  patterns: ['src/**/*.ts', 'lib/**/*.ts'],
  keywords: ['authentication', 'user', 'session'],
  excludes: ['*.test.ts', '*.spec.ts']
};

// Dispatch to retrieval agent
const candidates = await retrieveFiles(initialQuery);
阶段 2:评估

评估检索到的内容的相关性:

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):包含相关模式或类型
  • 低 (0.2-0.4):略微相关
  • 无 (0-0.2):不相关,排除
阶段 3:优化

根据评估结果更新搜索条件:

javascript
function refineQuery(evaluation, previousQuery) {
  return {
    // Add new patterns discovered in high-relevance files
    patterns: [...previousQuery.patterns, ...extractPatterns(evaluation)],

    // Add terminology found in codebase
    keywords: [...previousQuery.keywords, ...extractKeywords(evaluation)],

    // Exclude confirmed irrelevant paths
    excludes: [...previousQuery.excludes, ...evaluation
      .filter(e => e.relevance < 0.2)
      .map(e => e.path)
    ],

    // Target specific gaps
    focusAreas: evaluation
      .flatMap(e => e.missingContext)
      .filter(unique)
  };
}
阶段 4:循环

使用优化后的条件重复(最多 3 个周期):

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);

    // Check if we have sufficient context
    const highRelevance = evaluation.filter(e => e.relevance >= 0.7);
    if (highRelevance.length >= 3 && !hasCriticalGaps(evaluation)) {
      return highRelevance;
    }

    // Refine and continue
    query = refineQuery(evaluation, query);
    bestContext = mergeContext(bestContext, highRelevance);
  }

  return bestContext;
}

实际示例

示例 1:错误修复上下文
任务:"修复身份验证令牌过期错误"

循环 1:
  分发:在 src/** 中搜索 "token"、"auth"、"expiry"
  评估:找到 auth.ts (0.9)、tokens.ts (0.8)、user.ts (0.3)
  优化:添加 "refresh"、"jwt" 关键词;排除 user.ts

循环 2:
  分发:搜索优化后的关键词
  评估:找到 session-manager.ts (0.95)、jwt-utils.ts (0.85)
  优化:上下文已充分(2 个高相关文件)

结果:auth.ts、tokens.ts、session-manager.ts、jwt-utils.ts
示例 2:功能实现
任务:"为API端点添加速率限制"

周期 1:
  分发:在 routes/** 中搜索 "rate"、"limit"、"api"
  评估:无匹配项 - 代码库使用 "throttle" 术语
  优化:添加 "throttle"、"middleware" 关键词

周期 2:
  分发:搜索优化后的术语
  评估:找到 throttle.ts (0.9)、middleware/index.ts (0.7)
  优化:需要路由模式

周期 3:
  分发:搜索 "router"、"express" 模式
  评估:找到 router-setup.ts (0.8)
  优化:上下文已足够

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

与智能体集成

在智能体提示中使用:

markdown
在为该任务检索上下文时:
1. 从广泛的关键词搜索开始
2. 评估每个文件的相关性(0-1 分制)
3. 识别仍缺失哪些上下文
4. 优化搜索条件并重复(最多 3 个循环)
5. 返回相关性 >= 0.7 的文件

最佳实践

  1. 先宽泛,后逐步细化 - 不要过度指定初始查询
  2. 学习代码库术语 - 第一轮循环通常能揭示命名约定
  3. 跟踪缺失内容 - 明确识别差距以驱动优化
  4. 在“足够好”时停止 - 3 个高相关性文件胜过 10 个中等相关性文件
  5. 自信地排除 - 低相关性文件不会变得相关

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 4.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
