Claude 代理技能：从第一原理的深入探讨

Claude’s Agent Skills system represents a sophisticated prompt-based meta-tool architecture that extends LLM capabilities through specialized instruction injection. Unlike traditional function calling or code execution, skills operate through prompt expansion and context modification to modify how Claude processes subsequent requests without writing executable code.

Claude 的代理 Skills 系统代表了一种复杂的基于提示的元工具架构，通过专门的指令注入扩展 LLM 能力。与传统的函数调用或代码执行不同，skills 通过 提示扩展 和 上下文修改 来修改 Claude 处理后续请求的方式，而无需编写可执行代码。

This deep dive deconstructs Claude’s Agent Skills system from first principles, documents the architecture where a tool named “Skill” acts as a meta-tool for injecting domain-specific prompts into the conversation context. We’ll walk through the complete lifecycle using the skill-creator and internal-comms skill as case studies, examining everything from file parsing to API request structure to Claude’s decision-making process.

本次深入探讨从基本原理解构 Claude 的代理 Skills 系统，记录一个名为 Skill 的工具的架构，该工具充当将特定领域提示注入对话上下文的元工具。我们将通过使用 skill-creator 和 internal-comms 技能作为案例研究，逐步走过完整的生命周期，检查从文件解析到 API 请求结构再到 Claude 的决策过程的所有内容。

Claude Agent Skills Overview

Claude代理技能概述

Claude uses Skills to improve how it performs specific tasks. Skills are defined as folders that include instructions, scripts, and resources that Claude can load when needed. Claude uses a declarative, prompt-based system for skill discovery and invocation. The AI model (Claude) makes the decision to invoke skills based on textual descriptions presented in its system prompt. There is no algorithmic skill selection or AI-powered intent detection at the code level. The decision-making happens entirely within Claude’s reasoning process based on the skill descriptions provided.

Claude使用Skills来改善其执行特定任务的方式。Skills被定义为包含指令、脚本和资源的文件夹，Claude可以在需要时加载。Claude使用声明式、基于提示的系统进行技能发现和调用。AI模型（Claude）根据其系统提示中呈现的文本描述做出调用skills的决定。在代码层面上没有算法skill选择或AI驱动的意图检测。决策完全发生在Claude的推理过程中，基于提供的技能描述。

Skills are not executable code. They do NOT run Python or JavaScript, and there’s no HTTP server or function calling ha...
