gemini-set

Uniform Gemini CLI settings with ease

gemini-set is an installation-time configurator for projects. When installed, it automatically creates a .gemini directory in the consuming project and writes a settings.json file populated with a predefined configuration. This package is intended for developers who want a repeatable, standardized Gemini CLI configuration across multiple projects with zero manual setup.

---

Features

• Creates .gemini/ in the root of the consuming project at install-time.
• Writes a populated settings.json with opinionated defaults.
• Does not overwrite an existing settings.json (safe-by-default).
• Works during npm install, including when installed as a dependency.
• Uses INIT_CWD to ensure files are written to the correct project root.

---

Installation

Install from npm:

npm install gemini-set

After installation, your project will contain:

.gemini/
└── settings.json

If .gemini/settings.json already exists, the installer logs a notice and skips writing to avoid overwriting user-modified configuration.

Overwriting existing settings

By default, the installer does not overwrite an existing settings file.
If you want an overwrite or merge mode, you can modify the postinstall.js script to fit your use case.

If you want optional --force or --merge modes, open an issue or submit a PR.
