    A3.9/5.0

    Scored across 8 tools

    Disambiguation5/5

    Each tool has a clearly distinct purpose: batch rendering, cloning templates, generating images, fetching details, usage, listing brand kits, listing templates, and uploading images. There is no overlap or ambiguity.

    Naming Consistency5/5

    All tool names follow a consistent verb_noun pattern using lowercase and underscores, making them predictable and easy to understand.

    Tool Count5/5

    With 8 tools, the server covers the essential operations for image generation (listing templates, generating, batching, fetching, usage, uploading, cloning templates, and listing brand kits) without being bloated or too sparse.

    Completeness3/5

    The core workflow of generating images from templates is well-covered, but the lack of tools to create or update brand kits and delete images are noticeable gaps that limit the agent's ability to manage assets fully.
