List all Shared Slice models from Prismic Custom Types API.
AI agents call prismic_get_shared_slices to retrieve information from Prismic Content MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about Shared Slice models from the Prismic Custom Types API. It performs a read-only query operation with no side effects, no data modification, and no irreversible actions. The minimal blast radius and lack of destructive capability justify a 'low' severity rating.
From the tool's definition Tool name contains 'get' and description states 'List all Shared Slice models' — both indicate data retrieval with no modification or deletion.
