What it does
Crud is an agent skill from wujun728/jun_java_plugin. 一键生成完整业务模块代码（SQL/Entity/DAO/XML/Repository/Service/Controller/Mapper/POJO），用于创建新的业务功能
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Databases, covering SQL and Database migrations. It works with SQL, Java, Redis and Spring Boot. The repository describes itself as: junjavaplugin 整合Java企业级各种开发组件、开箱即用、不写重复代码；目前已集成javaplugin50多个，springplugin组件100+，springboot组件100+，各种项目模板，涵盖开发各种场景如minio、七牛云、云短信、设计模式、多数据源、分布式Session、分布式事务、分布式锁、消息队列、并发框架、模板引擎、规则引擎….
When your agent uses it
- Tasks that involve SQL
- Tasks that involve Database migrations
Example prompts
- “/crud”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- 查找 src/main/java 目录下的Java文件
- 读取已有Java文件的 package 声明
- 分析项目的根包名结构
What it can do on your machine
Read from SKILL.md and the folder at commit 5651979. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are java).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Crud loads about 2.8k tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 229 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 229 words (~2,782 tokens).

Questions about Crud
What does Crud do?
一键生成完整业务模块代码（SQL/Entity/DAO/XML/Repository/Service/Controller/Mapper/POJO），用于创建新的业务功能. Crud is an agent skill from wujun728/jun_java_plugin.
When should I use Crud?
Crud fits situations like: tasks that involve SQL; tasks that involve Database migrations.
How do I install Crud in Claude Code?
Run `npx skills add wujun728/jun_java_plugin --skill crud -a claude-code`. Or copy the skill folder (.claude/skills/crud in wujun728/jun_java_plugin) into .claude/skills/crud in your project. Claude Code loads it when a task matches its description.
How do I install Crud in Codex?
Run `npx skills add wujun728/jun_java_plugin --skill crud -a codex`. Or copy the skill folder (.claude/skills/crud in wujun728/jun_java_plugin) into .agents/skills/crud in your project. Codex loads it when a task matches its description.
Can I use Crud in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add wujun728/jun_java_plugin --skill crud -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/crud, .gemini/skills/crud, .github/skills/crud and .opencode/skills/crud in your project.
What does Crud need to run?
SKILL.md names no scripts, command-line tools or credentials: Crud is instructions for the agent only.
Does Crud access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

What licence does Crud use?
No licence was found for Crud or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Crud use?
About 2.8k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
