Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description alone must disclose behavioral aspects. It does not mention whether this operation is read-only, any rate limits, or potential side effects. This lack of transparency is a significant gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very concise and straightforward, consisting of a single sentence. It is appropriately short and focuses on the core purpose without extraneous text, though it lacks detailed structure.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the low schema coverage and missing parameter explanations, the description is far from complete. It does not provide enough context for an agent to understand how to use the tool effectively, including pagination via bookmark, filtering via pin_filter, or page_size limits.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema defines three parameters (bookmark, page_size, pin_filter) but provides no descriptions. The tool description does not explain what these parameters control or how they affect results. With zero schema coverage and no compensation in the description, parameter semantics are entirely unexplained.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the resource (pins) and the scope (belonging to the authenticated account), which conveys the primary purpose. However, it does not explicitly distinguish this from sibling tools like pinterest_search_my_pins, so it does not fully achieve a perfect score.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this tool versus alternatives such as pinterest_search_my_pins or pinterest_list_boards. The description simply states what it does without any contextual usage instructions.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
