B3.4/5.0

Behavior4/5

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

With annotations already declaring readOnly/openWorld/non-idempotent/non-destructive, the description still adds real value: credit cost per successful call, plan-dependent actual cost, re-charge on repeated calls, and an untrusted-data warning. The re-charge warning usefully corroborates idempotentHint=false. It does not cover rate limits or pagination limits beyond the schema.

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?

Four short sentences, front-loaded with purpose, then cost, then a safety note. Every sentence carries information; the only gap is that the purpose sentence is narrower than the tool actually is.

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

Completeness3/5

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

For a 15-parameter tool with a nested sort object and no output schema, the description leaves the response shape unexplained (returnFields is only described in the schema) and does not mention the non-keyword filter modes. Annotations plus full schema coverage keep it merely adequate rather than inadequate.

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 the schema already documents all 15 parameters including enums, defaults and nested sort fields. The description adds only that keyword/ASIN are the two headline modes and omits that brand, sellerName and nodeIdPath can be used alone, so it neither compensates nor misleads.

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?

The first sentence states a specific verb and resource ("Search products") and names the two primary input modes (keyword, ASIN list). However, it under-describes the tool: the schema also accepts brand, sellerName and nodeIdPath as standalone filters, and nothing distinguishes this from siblings like amazon_product_research or amazon_market_goods.

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?

There is no when-to-use guidance and no named alternative among the ~45 sibling tools, several of which (amazon_product_research, amazon_market_goods, amazon_asin_detail) plausibly overlap. The only contextual guidance is cost-related, not selection-related.

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