What it does
Java Install Skill is an agent skill from jiushiwon/wg-skills. Java 安装子技能。支持 apt/dnf/Docker 方式安装指定版本的 JDK，幂等检测，已安装则提示。当用户说「安装 Java」「装 Java」时触发。
Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `README.md` and `references/install-commands.md`).
It sits in DevOps & Cloud, covering Skill management and Containers. It works with Java and Docker. The licence is Apache-2.0.
When your agent uses it
- Tasks that involve Skill management
- Tasks that involve Containers
Example prompts
- “/java-install-skill”
Requirements
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit a4a640b. 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
Shell commands in SKILL.md call:
dockerjavaaptdnfbrewwinget
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use docker, which can reach the network depending on how they are called.
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
Java Install Skill loads about 299 tokens when it runs, and up to ~1.2k if it reads all its reference files. Until then it costs about 25 tokens; SKILL.md has 54 words of instructions outside code blocks.
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.

Java Install Skill
Overview
本技能负责在目标服务器上安装 Java（JDK）。支持多种安装方式，幂等检测。
When to Use
触发词：
- 安装 Java
- 装 Java
- install java
交互流程
1. 检测当前系统（OS + 版本 + 包管理器）
2. 询问安装方式（包管理器 / Docker）
3. 询问版本（21 / 17 LTS / 11）
4. 检测是否已安装
5. 执行安装（幂等）
6. 输出验证命令安装方式
包管理器安装
| OS | 安装命令 |
|---|---|
| Ubuntu/Debian | apt install openjdk-21-jdk |
| CentOS/RHEL | dnf install java-21-openjdk |
| macOS | brew install openjdk@21 |
| Windows | winget install OpenJDK.21 |
Docker 安装
docker pull openjdk:21
docker run -d --name java-runtime -v /app:/app openjdk:21 java -jar /app/app.jar版本选择
- Java 21（最新 LTS）
- Java 17（LTS，稳定）
- Java 11（老项目兼容）
幂等检测
# 检测是否已安装
java -version 2>&1 | head -1
# 检测指定版本
java -version 2>&1 | grep "21"输出
# Java 安装完成
## 系统信息
- OS: Ubuntu 22.04 LTS
- 包管理器: apt
## 安装结果
- 版本: OpenJDK 21
- 安装方式: apt
- 状态: ✅ 已安装
