+# HugeGraph 仓库知识助手
+
+[English](README.md) | [中文](README-zh.md)
+
+这个独立模块将 [Apache HugeGraph](https://github.com/apache/hugegraph) 源码仓库问答能力打包为 Claude Code 和 Codex 可安装的 skill。
+
+DeepWiki 是底层线上知识库和 MCP 传输通道：
+
+```text
+https://deepwiki.com/apache/hugegraph
+https://mcp.deepwiki.com/mcp
+```
+
+## 功能
+
+- 回答 HugeGraph 架构、模块、API、存储后端、schema、traversal、配置、构建、测试和实现细节相关问题。
+- 使用 `read_wiki_contents` 构建本地 DeepWiki wiki 缓存，并优先搜索缓存。
+- 当缓存内容不能直接、精准回答问题时，使用 `ask_question` 获取线上答案。
+- 普通问答不会 clone 上游源码仓库。
+
+## 前置要求
+
+- Python 3.9 或更高版本，用于运行随附的 MCP 客户端脚本。
+- 当前环境需要能访问 `https://mcp.deepwiki.com/mcp`。
+

+
+## Claude Code 安装
+
+从当前仓库安装：
+
+```bash
+cd tools/ai/hugegraph-deepwiki-skill
+claude plugin marketplace add "$(pwd)"
+claude plugin install hugegraph-deepwiki-skill@hugegraph-deepwiki-skill
+```
+
+从已发布分支安装时，先 clone 仓库，再从本地模块路径安装：
+
+```bash
+git clone -b <branch> https://github.com/<owner>/hugegraph.git
+cd hugegraph/tools/ai/hugegraph-deepwiki-skill
+claude plugin marketplace add "$(pwd)"
+claude plugin install hugegraph-deepwiki-skill@hugegraph-deepwiki-skill
+```
+
+手动安装用户级 skill：
+
+```bash
+mkdir -p ~/.claude/skills
+cp -R plugins/hugegraph-deepwiki-skill/skills/hugegraph-deepwiki-skill ~/.claude/skills/
+```
+
+### 让 Claude Code 自动安装
+
+在 HugeGraph 仓库根目录的 Claude Code 里粘贴：
+
+```text
+Install the HugeGraph repository assistant from this checkout. Enter `tools/ai/hugegraph-deepwiki-skill`, run `claude plugin marketplace add "$(pwd)"`, then run `claude plugin install hugegraph-deepwiki-skill@hugegraph-deepwiki-skill`. Do not hardcode absolute paths.
+```
+
+## Codex 安装
+
+从当前仓库安装：
+
+```bash
+cd tools/ai/hugegraph-deepwiki-skill
+codex plugin marketplace add "$(pwd)"
+codex plugin add hugegraph-deepwiki-skill@hugegraph-deepwiki-skill
+```
+
+从已发布分支安装时，先 clone 仓库，再从本地模块路径安装：
+
+```bash
+git clone -b <branch> https://github.com/<owner>/hugegraph.git
+cd hugegraph/tools/ai/hugegraph-deepwiki-skill
+codex plugin marketplace add "$(pwd)"
+codex plugin add hugegraph-deepwiki-skill@hugegraph-deepwiki-skill
+```
+
+如果当前 Codex 版本不能直接安装 plugin，可以安装 raw skill：
+
+```bash
+CODEX_HOME="${CODEX_HOME:-$HOME/.codex}"
+mkdir -p "$CODEX_HOME/skills"
+cp -R plugins/hugegraph-deepwiki-skill/skills/hugegraph-deepwiki-skill "$CODEX_HOME/skills/"
+```
+
+### 让 Codex 自动安装
+
+在 HugeGraph 仓库根目录的 Codex 里粘贴：
+
+```text
+Install the HugeGraph repository assistant from this checkout. Enter `tools/ai/hugegraph-deepwiki-skill`, run `codex plugin marketplace add "$(pwd)"`, then run `codex plugin add hugegraph-deepwiki-skill@hugegraph-deepwiki-skill`. If this Codex build has no plugin add command, copy `plugins/hugegraph-deepwiki-skill/skills/hugegraph-deepwiki-skill` into `${CODEX_HOME:-$HOME/.codex}/skills`. Do not hardcode absolute paths.
+```
+
+## 使用方式
+
+安装后，可以在提问时显式指定：
+
+```text
+Use $hugegraph-deepwiki-skill to explain HugeGraph schema and traversal behavior.
+```
+
+HugeGraph AI 相关问题请安装 `apache/hugegraph-ai` 仓库中的独立 HugeGraph AI 仓库知识助手。

+# HugeGraph Repository Assistant
+
+[中文](README-zh.md) | [English](README.md)
+
+This standalone module packages a Claude Code and Codex skill for answering questions about the [Apache HugeGraph](https://github.com/apache/hugegraph) source repository.
+
+DeepWiki is used as the online knowledge and MCP transport layer:
+
+```text
+https://deepwiki.com/apache/hugegraph
+https://mcp.deepwiki.com/mcp
+```
+
+## What It Does
+
+- Answers repository-grounded questions about HugeGraph architecture, modules, APIs, storage backends, schema, traversal, configuration, build, tests, and implementation details.
+- Uses `read_wiki_contents` to build a local DeepWiki wiki cache and searches that cache before answering.
+- Uses `ask_question` when the cached context does not directly and precisely answer the question.
+- Avoids cloning upstream repositories for ordinary Q&A.
+
+## Requirements
+
+- Python 3.9 or later for the bundled MCP client script.
+- Network access to `https://mcp.deepwiki.com/mcp`.
+

+
+## Claude Code Install
+
+From this repository:
+
+```bash
+cd tools/ai/hugegraph-deepwiki-skill
+claude plugin marketplace add "$(pwd)"
+claude plugin install hugegraph-deepwiki-skill@hugegraph-deepwiki-skill
+```
+
+From a published branch, clone the repository first and install from the local module path:
+
+```bash
+git clone -b <branch> https://github.com/<owner>/hugegraph.git
+cd hugegraph/tools/ai/hugegraph-deepwiki-skill
+claude plugin marketplace add "$(pwd)"
+claude plugin install hugegraph-deepwiki-skill@hugegraph-deepwiki-skill
+```
+
+Manual user-level skill install:
+
+```bash
+mkdir -p ~/.claude/skills
+cp -R plugins/hugegraph-deepwiki-skill/skills/hugegraph-deepwiki-skill ~/.claude/skills/
+```
+
+### Ask Claude Code To Install It
+
+Paste this into Claude Code from the HugeGraph repository root:
+
+```text
+Install the HugeGraph repository assistant from this checkout. Enter `tools/ai/hugegraph-deepwiki-skill`, run `claude plugin marketplace add "$(pwd)"`, then run `claude plugin install hugegraph-deepwiki-skill@hugegraph-deepwiki-skill`. Do not hardcode absolute paths.
+```
+
+## Codex Install
+
+From this repository:
+
+```bash
+cd tools/ai/hugegraph-deepwiki-skill
+codex plugin marketplace add "$(pwd)"
+codex plugin add hugegraph-deepwiki-skill@hugegraph-deepwiki-skill
+```
+
+From a published branch, clone the repository first and install from the local module path:
+
+```bash
+git clone -b <branch> https://github.com/<owner>/hugegraph.git
+cd hugegraph/tools/ai/hugegraph-deepwiki-skill
+codex plugin marketplace add "$(pwd)"
+codex plugin add hugegraph-deepwiki-skill@hugegraph-deepwiki-skill
+```
+
+If your Codex build cannot install plugins directly, install the raw skill:
+
+```bash
+CODEX_HOME="${CODEX_HOME:-$HOME/.codex}"
+mkdir -p "$CODEX_HOME/skills"
+cp -R plugins/hugegraph-deepwiki-skill/skills/hugegraph-deepwiki-skill "$CODEX_HOME/skills/"
+```
+
+### Ask Codex To Install It
+
+Paste this into Codex from the HugeGraph repository root:
+
+```text
+Install the HugeGraph repository assistant from this checkout. Enter `tools/ai/hugegraph-deepwiki-skill`, run `codex plugin marketplace add "$(pwd)"`, then run `codex plugin add hugegraph-deepwiki-skill@hugegraph-deepwiki-skill`. If this Codex build has no plugin add command, copy `plugins/hugegraph-deepwiki-skill/skills/hugegraph-deepwiki-skill` into `${CODEX_HOME:-$HOME/.codex}/skills`. Do not hardcode absolute paths.
+```
+
+## Usage
+
+After installation, ask for the skill explicitly when needed:
+
+```text
+Use $hugegraph-deepwiki-skill to explain HugeGraph schema and traversal behavior.
+```
+
+For HugeGraph AI questions, install the separate HugeGraph AI repository assistant from the `apache/hugegraph-ai` repository instead.
