validate

Checks all YAML in a project against the schema and path/reference rules.

npx @slide-spec/cli validate

Validates:

• site.yaml structure and required fields
• presentations/index.yaml entries and explicit file paths
• Each presentation's presentation.yaml and generated.yaml
• Cross-file consistency for ids and declared file paths
• Template-specific slide content rules

On success, prints Content is valid. On failure, prints the specific error and exits with code 1. For example:

site.yaml.site.title must not be blank.

or for a template issue:

presentation document.presentation.slides[2].content.sections is required.

The error tells you which file and field to fix. Correct the YAML and run validate again.

Run after editing YAML and before build or serve.
