walmart_product

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

The description discloses that the tool uses 'credential-free public Walmart data' and is 'rendered from the product page through proxied browser renderers', providing important behavioral context beyond the basic operation. No annotations to contradict.

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?

Concise two-sentence description that efficiently conveys purpose and key behaviors. No wasted words.

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?

The description lists the returned data fields and explains the data source, providing sufficient context for an agent to understand what the tool does and what to expect. Without an output schema, it could benefit from more structural details.

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?

The parameter is fully described in the schema with a clear explanation of how to obtain it from the URL. The description does not provide additional parameter semantics beyond what the schema already offers.

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 the verb 'Get' with the resource 'Walmart product', and lists the returned fields (price, availability, etc.), clearly differentiating it from 'walmart_search' and 'walmart_product_reviews'.

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?

Implicit usage context is provided by listing the returned fields (product details), but there is no explicit guidance on when to use this versus walmart_search or walmart_product_reviews.

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