TDQS

D1.7/5.0
Behavior1/5

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

Annotations declare readOnlyHint=false and openWorldHint=true, but the description adds zero behavioral context — no indication of result size, cost, rate limits, or what the filtered output represents. With 59 filter parameters and no output schema, this silence leaves the agent blind to the tool's behavior.

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

Conciseness2/5

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

It is short, but the single sentence is pure redundancy with the title and earns no place. Conciseness here comes from under-specification rather than efficiency.

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

Completeness1/5

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

A 59-parameter, zero-required, open-world query tool with no output schema needs the description to explain what a filtered result is and how to drive it; instead there is nothing beyond the title. An agent cannot confidently invoke it correctly from this definition alone.

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 each of the 59 parameters is already documented in the schema; the description adds no interpretation of how parameters combine (e.g. AND semantics of _Gte/_Lte pairs, default when no filters are supplied). Baseline 3 applies because the schema does all the work.

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

Purpose2/5

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

The description is a verbatim restatement of the tool title/name ('Amazon ABA & Business Insights: opportunity/search By Metrics API') with no additional explanation. It conveys the domain (Amazon ABA opportunity data) but never says what the tool actually does with the 59 metric filters — e.g. that it returns niches/markets matching supplied metric thresholds.

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

Usage Guidelines1/5

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

No usage guidance at all: no when-to-use, no exclusions, and no mention of the closely related siblings such as nexscope_amazon_opportunity_report_by_keyword or nexscope_amazon_niche_info_by_keyword. An agent has no basis for choosing this tool over those.

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