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

With no annotations provided, the description carries the full burden of behavioral disclosure. It provides zero information about side effects, return format, expected inputs, or any operational details. An agent has no basis to predict 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 non-informative phrase. This is not conciseness but extreme under-specification. It provides no content to structure or front-load, and fails to communicate even the basic function.

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 tool with two parameters and no output schema, the description is wholly inadequate. It lacks any explanation of inputs, expected results, failure modes, or relationship to the sibling tool. An agent cannot safely or correctly invoke it.

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 schema has 0% coverage and the description adds nothing about the 'url' or 'maxTimeout' parameters. Neither the schema nor the description explains their meaning, format, or purpose. The agent cannot correctly populate these fields.

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 'V1 Amazon Product' is a version label, not a functional description. It neither states a verb nor clarifies the resource's purpose, making it impossible for an agent to infer what the tool does. It is essentially a restatement of the tool name with a version prefix.

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?

There is no guidance on when to use this tool versus the sibling amazon_search. No context, no exclusions, no alternative routing. The description is silent on usage entirely.

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