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

With no annotations, the description carries the full burden for behavioral disclosure. It lists operations and required parameters but does not mention safety (read-only nature), rate limits, response format, or error behavior. The operations appear read-only, but this is not explicitly stated.

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 well-structured with a clear summary and a list of operations with required parameters. It is front-loaded and free of unnecessary words, though the bullet-like format could be slightly more compact.

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 tool has five operations, no annotations, and no output schema. The description explains how to invoke each operation with required args, which is adequate for basic use. However, it lacks return value descriptions, pagination details, or examples, leaving gaps for a richer multi-operation data tool.

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 input schema only defines a generic 'args' object; the description adds the actual parameter names (query, category_id, product_id) for each operation. This is essential and goes beyond the schema. However, it does not provide types or optional parameters, so it is not fully exhaustive.

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 tool's scope: 'Walmart product search, products by category, product details, offers and reviews.' Each operation has a specific verb and resource, and the Walmart-specific focus distinguishes it from sibling real-time data tools.

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 usage for accessing Walmart product data through its listed operations, but it does not explicitly compare with alternative tools or state when not to use this tool. No exclusions or alternative recommendations are provided.

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