create_pinterest_pin

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

No annotations are available. The description only says 'Create', indicating a write operation, but lacks details on side effects, required permissions, error handling (e.g., invalid image URL), or any consequences of the action.

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 sentence, which is too minimal for a tool with 7 parameters. It lacks structure and essential information, making it under-specified rather than concise.

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?

No output schema exists, and the description provides no information about return values. With 7 parameters and low schema coverage, the description fails to make the tool usable without additional external knowledge.

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 only 43% (3 of 7 parameters described). The description does not add meaning beyond the schema; it only mentions 'image URL' (matching media_source_url). It fails to explain optional parameters like title, description, or 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'), the resource ('Pinterest pin'), and the source ('from an image URL'). This directly differentiates it from sibling tools like list_pinterest_pins (listing) and search_pinterest_pins (searching).

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?

No guidance is provided on when to use this tool versus other Pinterest tools, such as when to create vs. update pins, or any prerequisites (e.g., needing a board). The description is silent on usage context.

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