create_pinterest_pin

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

No annotations exist, so the description carries full burden. It does not disclose behavioral traits such as authentication, rate limits, or error behavior (e.g., if the image URL is invalid). The agent is left uninformed about access_token requirements or mutability.

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 a single, front-loaded sentence that is concise. However, it is too brief to cover necessary details, but the brevity itself earns a 4 for 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?

With 7 parameters and no output schema, the description is insufficient. It omits explanation of optional parameters, the destination link, and board section ID, leaving the agent without enough context to use the tool effectively.

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?

Schema description coverage is 43% (3 of 7 parameters described). The description adds no new parameter information beyond what is in the schema, failing to compensate for undocumented parameters like title, description, board_section_id, and access_token.

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 action 'Create' and the resource 'Pinterest pin', and specifies that it uses an image URL as input. This distinguishes it from siblings like list_pinterest_pins and search_pinterest_pins.

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?

The description implies creation use case but provides no explicit guidance on when to use this tool versus alternatives, no prerequisites (e.g., board_id must exist), and no exclusions. The tool name and context suffice for basic selection.

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