Generator settings
Text only: no commands run or packages installed. Presets require their corresponding tools. Full output is a starter file; do not overwrite an existing package.json. Maximum 50 scripts, 4000 characters each. Do not enter secrets.
Inputs stay in page memory without transmission, storage or URL insertion.

Preview and complete output
Set fields or load a sample, then generate.
How to use this tool
Select presets or add a custom script, edit commands, choose the JSON output and generate. Review dependencies and shell behavior before using it elsewhere.
When not to use it
Commands are plain JSON text here. Starter package JSON does not infer or install dependencies and should not overwrite an existing package file.
