Jeecg Codegen New

What it does

When your agent uses it

• User asks to generate JeecgBoot CRUD code
• Create a new module
• Add/modify fields on existing module

Example prompts

• “generate code”
• “new entity”
• “add field”
• “/jeecg-codegen-new”

Requirements

• Python 3
• A credential in COLUMN_KEY

Workflow steps

6 steps, taken from the step headings in SKILL.md.

1. 1判断操作类型
2. 2收集参数（一次性问完）
3. 3展示摘要
4. 4调用脚本
5. 5处理特殊需求（模板没覆盖的部分）
6. 6后续操作

What it can do on your machine

Read from SKILL.md and the folder at commit 12760b9. 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

  Ships 3 files in scripts/ (Java and Python, from the files we listed), which the agent can run.

  Shell commands in SKILL.md call:

  • mysql
  • python
  • mvn
  • pnpm

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use pnpm, 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 these keys or tokens, usually read from environment variables:

  • COLUMN_KEY

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Jeecg Codegen New loads about 2.4k tokens when it runs, and up to ~8.3k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 581 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~66

When it runs · the whole SKILL.md, loaded when a task matches

~2.4k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~8.3k

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

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); the scripts in this folder are not scanned.
