product_offers

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

With no annotations, the description carries the full burden. 'Get' implies a read-only operation and 'current' indicates temporal freshness, but the description does not disclose the response shape, pagination, or any retailer-count limits. It is adequate but leaves behavioral details unstated.

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?

A single, front-loaded sentence with no filler. Every word contributes to scope or resource, making it an efficient and readable definition.

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?

For a one-required-parameter query tool with no output schema, this description is largely sufficient: it names the action, resource, scope, and temporal freshness. It could be more complete by hinting at the return structure or pagination, but the low complexity keeps this from being a major gap.

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 100%, and the schema already documents the identifier formats (barcode, ASIN, URL, model number, ShopSavvy ID). The description adds only 'for a product', so it does not meaningfully enrich parameter understanding beyond the schema.

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 uses a specific verb ('Get') and resource ('current pricing offers for a product from all retailers'), and 'all retailers' helps distinguish this from sibling product_offers_retailer. It clearly communicates what the tool does.

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 phrase 'from all retailers' provides clear context for when this tool should be used, and implicitly contrasts with retailer-specific siblings. It does not explicitly list exclusions or alternative tools, but the scope is unambiguous.

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