SkillSignal prompt templates

Provide the task, context, and acceptance criteria

These prompts were written by SkillSignal from the source structure; they are not upstream text.

Task-start prompt

Confirm source fit, inputs, and outputs before acting.

Use iterative-retrieval to help me with: [specific task]. Context: [files, data, or background]. Constraints: [environment, scope, and prohibited actions]. Before acting, check the pinned SKILL.md and explain which sections apply, what inputs are still missing, and what you will deliver.

Source-guided execution

Make the Agent explicitly follow the key extracted sections.

Apply the pinned iterative-retrieval source to [task]. Pay particular attention to these source sections: “何时激活”, “问题”, “解决方案:迭代检索”, “阶段 1:调度”, “阶段 2:评估”. Preserve the important decision at each step. Mark facts not covered by the source as “needs confirmation” instead of inventing them. Then verify the result against my acceptance criteria: [criteria].

Result-review prompt

Check omissions, permissions, and source drift before delivery.

Review the current iterative-retrieval result: (1) does it satisfy the original task; (2) were any applicable steps or limits in the pinned SKILL.md missed; (3) did it perform any unauthorized file, command, network, or data action; and (4) which conclusions remain unverified? List issues first, then fix only what the source or user authorization supports.

Output checklist

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:

// 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)
  };
}

阶段 4:循环

使用优化后的条件重复(最多 3 个周期):

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:

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
