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

The annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds useful behavioral context by listing returned fields and explaining that the price is the lowest of four license tiers and includes a licensing note.

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 two front-loaded sentences that efficiently summarize the operation and return payload. The field list is dense but earns its place by compensating for the absence of an output schema.

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 no output schema, the description appropriately explains the returned fields and pricing semantics. It is nearly complete for a read-only batch lookup, though it omits any sibling differentiation or error behavior.

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 coverage is 100%, so both product_ids and include_images are already documented in the input schema. The description reinforces the 1-50 limit and describes response content, but it does not add parameter meaning beyond what the schema provides.

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 states a specific verb and resource: returning display data for product IDs from the Creative Market API. It clearly defines the 1-50 ID scope and enumerates the returned fields, but it does not distinguish this tool from the sibling get_product tool.

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?

Usage is implied by the batch-oriented 'one to fifty product IDs' phrasing, which suggests this is for looking up multiple products at once. However, there is no explicit guidance on when to use this instead of get_product, search_products, or other siblings.

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