ToolCategoryRisk
add_slice_to_custom_typePURPOSE: Adds a slice to a custom type. USAGE: Required path for modifying Prismic slice registrations. Adds/registers/attaches a slice to a custom type and regenerates types. Do not edit custom type JSON files manually; this tool performs validation and follow-up steps. RETURNS: A message indicating whether the slice was added to the type or not, and detailed error messages if it is not.

how_to_model_slicePURPOSE: Provide detailed, opinionated guidance to create or update Prismic slice model files using modern best practices, including naming, file placement, allowed fields, shapes, and configuration. USAGE: Use FIRST for any Prismic slice creation or modeling request. Do not use for component or mock implementation. Input Type Selection Rules: - If the user attaches an image, include "image". - If the user attaches code, include "code". - Include "text" ONLY if the prompt contains model-related information (e.g., explicitly describes desired fields/structure, adds nuance, or overrides what is seen in the code/image). - It is acceptable to include multiple input types when each adds model-relevant signal per the rules above. RETURNS: Step-by-step modeling instructions, naming conventions, final Prismic model shapes, comprehensive field shape reference, opinionated modeling guidance, validation and testing steps.
