TDQS

C2.6/5.0

Behavior2/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=true and destructiveHint=false, so the safety profile is fully covered. The description adds no behavioral context beyond that - no mention of the 30-day result-retention window, latency, or that it reads results of an existing task; the only extra text is injected pricing boilerplate.

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

Conciseness3/5

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

The prose is brief and front-loaded, which is good, but the second half is an injected pricing block that conveys no task-relevant information. The one meaningful sentence is loosely worded, so brevity here reflects under-specification as much as economy.

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?

An output schema exists, so return values need not be explained, and annotations cover safety. However, for a task-result retrieval tool the description omits the submit-then-fetch workflow and the role of the id, leaving the agent to infer the operational context.

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%, and the schema itself richly documents the UUID task identifier and its 30-day validity, so the baseline is 3. The description adds no parameter meaning at all, but the schema carries the full burden adequately.

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

Purpose3/5

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

The description names the resource ('information about the product and ASINs of all its modifications listed on Amazon') but the verb is weak and generic ('will provide you with information'). It does not distinguish this tool from its obvious siblings like get_dataforseo_merchant_amazon_asin_fetch_html or the post_..._asin_submit counterpart, so an agent cannot tell why to pick this one without reading the schemas.

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 guidance on when to use this tool versus alternatives. Critically, nothing states that the required 'id' is a task identifier produced by a prior submit call (post_dataforseo_merchant_amazon_asin_submit), which is the key routing decision for this family of tools.

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