iterative-retrieval

iterative-retrieval is a skill for Claude Code, Codex from Luohaothu/everything-codex. It costs 23 tokens per session (1,575 once invoked), scanned A, original, MIT.

A step-by-step method for finding the right code context for a coding task. It repeatedly retrieves possible files, checks their relevance, improves the search, and then searches again when needed.

In plain words
What is it for?
Use it in multi-agent workflows when an agent needs to locate related files, discover existing code patterns, or learn the project’s terminology before making a change.
Why use it?
A coding agent may receive too little context to understand a task or too much to process efficiently. This method helps it find relevant files without relying on guesswork or loading an entire codebase.

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

iterative-retrieval 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.

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。

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:

┌─────────────────────────────────────────────┐
│                                             │
│   ┌──────────┐      ┌──────────┐            │

│        Max 3 cycles, then proceed           │
└─────────────────────────────────────────────┘

阶段 1:调度

初始的广泛查询以收集候选文件:

// 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:

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:

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)
  };
}

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.

iterative-retrieval is a skill published in the GitHub repository Luohaothu/everything-codex (25 stars, last pushed 2mo ago), licensed MIT. It adds 23 tokens to every session and 1,575 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
