FAQPage Schema

How do I scaffold a new Gemini CLI extension?▼

To scaffold a Gemini CLI extension, use the initialization script to create a standardized project layout, core files, and a starter gemini-extension.json manifest. This ensures a correct folder structure and baseline configuration.

What is the best way to validate a gemini-extension.json manifest?▼

Validating a gemini-extension.json manifest involves checking for missing files, invalid JSON syntax, and adherence to Gemini extension guidelines. The validation script automates these checks to verify manifest correctness across projects.

How does extension scaffolding work for Gemini CLI dev-tools?▼

Extension scaffolding for Gemini CLI dev-tools works by automatically generating the required folder structures and a gemini-extension.json manifest. This enforces best practices and reduces manual setup errors for extension authors.

Do I need to manually create the project layout for a Gemini extension?▼

You do not need to manually create the project layout for a Gemini extension. The scaffolding script initializes the folder structure and manifest automatically, enforcing a standardized layout across your projects.

Can I check my Gemini extension for missing manifests and invalid JSON?▼

You can check your Gemini extension for missing manifests and invalid JSON by running the validation script. It verifies structural compliance and checks the gemini-extension.json schema against official guidelines.

Why does my Gemini CLI extension fail validation checks?▼

Gemini CLI extension validation fails when the gemini-extension.json manifest is missing, contains invalid JSON, or violates official schema guidelines. Use the validation script to identify and resolve these structural compliance issues.
