getProductPrices

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

No annotations are provided, so the description carries full burden. It only states the data is crowd-sourced but fails to disclose behavioral traits such as read-only nature, rate limits, data freshness, or return format. This is insufficient for an agent to understand tool behavior.

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 with 14 words, no wasted text, and front-loads the action. It is appropriately concise, though additional structure (e.g., stating the output format) could enhance clarity without harming conciseness.

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 tool has 3 parameters (including pagination) and no output schema or annotations, the description is incomplete. It fails to explain pagination, output structure, or any constraints. A complete description would mention pagination details and return data format.

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 33% (only barcode described). The description does not add any meaning for page or pageSize parameters, which are left undocumented. The description should explain that page and pageSize control pagination, but it does not.

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 verb 'Get' and the resource 'crowd-sourced price data for a specific product', and adds a benefit 'see where it costs less'. This effectively communicates the tool's purpose and distinguishes it from siblings like getProductByBarcode and searchPrices.

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 use for a specific product via barcode, but does not explicitly state when to use this tool versus alternatives like searchPrices or getRecentPrices. No exclusions or alternative tool names are provided.

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