B3.1/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, openWorldHint=true, destructiveHint=false, and idempotentHint=false. The description genuinely adds to them: a per-call credit cost with repeated charges, consistent with idempotentHint=false, and a prompt to treat returned data as untrusted. It says nothing about pagination in the multi-page result set, but because annotations cover the safety profile, a 3 is fair.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, with the core purpose front-loaded and no wasted preamble. The billing line is slightly hedged ('actual cost follows your plan') but still earns its place as cost disclosure.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

There are 36 parameters and no output schema, yet the description never says what the returned 'conversion metrics' contain, what fields are available for returnFields, or how the many min and max filters interact. For a tool this complex with no output schema, the description should carry more of that burden.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all 36 parameters, including the marketplace and timeType enums, are documented in the schema. The description adds no meaning about the min and max filter pairs, returnFields, or matchType, so the baseline of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

A specific verb and resource: 'Retrieve keyword conversion metrics for an Amazon keyword.' That is unambiguous about the operation. However, it gives no hint of how it differs from several close siblings such as amazon_keyword_research, amazon_keyword_miner, amazon_keyword_order, and amazon_traffic_keyword, so the agent must guess which one to use.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description never says when to pick this tool rather than a sibling, nor does it name the conditions under which another tool is appropriate. The only extra context is billing, which is not usage guidance. The agent is left to infer that this is for conversion metrics on a single keyword.

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