create_pin

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

No annotations are provided, but the description discloses the key side effect of posting and the lack of a sandbox, while offering dry_run as a safe validation path. It does not mention auth or rate limits, so it is not fully transparent.

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?

Two tight sentences with no filler; the main action, image source alternatives, and dry_run behavior are all communicated efficiently.

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?

Provides enough context for basic invocation: what the tool does, how to supply an image, and how to validate without posting. It does not explicitly state that image_url and image_path are mutually exclusive, but schema requirements and the presence of an output schema cover most remaining needs.

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 descriptions are absent, but the description adds meaning for image_url, image_path, and dry_run. The remaining parameters rely on self-explanatory names and titles and are not elaborated, so coverage is partial.

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?

States it creates a new Pinterest pin and explicitly mentions the image source options and dry_run validation. It is clearly distinct from sibling tools like update_pin, delete_pin, and bulk_create_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?

Provides useful conditional guidance for dry_run and for choosing between image_url and image_path. However, it does not explicitly contrast with bulk_create_pins or update_pin, so tool-selection context remains somewhat implicit.

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