TDQS

A3.9/5.0
Behavior3/5

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

Annotations already declare readOnly, idempotent, non-destructive and openWorld, so the safety profile is covered. The description goes beyond them with a concrete cost model (5 + 5 per 100 rows, default 10 credits), a 7-day cache note, and the non-obvious exclusion of the target product itself, which are genuinely useful operational facts.

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?

Labeled sections (Use when / Not for / Returns / Cost / Example) make it scannable and front-loaded with the core definition. Every sentence carries information; the only near-redundancy is the Returns field, which largely restates the output schema.

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?

With an output schema present, the return-value listing is technically optional but the ASIN-only caveat and the pointer to amazon_get_product for titles fill a real gap. Cost, caching and the self-exclusion rule round out an otherwise complete picture for a 7-parameter, paginated, credit-metered tool.

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 coverage is 100% and the schema already documents asin, limit, cursor, dry_run, language, location and max_credits in detail. The description adds a worked example {"asin": ..., "limit": 20} and ties row count to credit cost, but adds no semantics for cursor, dry_run or max_credits beyond what the schema states.

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

Purpose5/5

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

"Amazon products that compete with one product for the same searches, with how many they share and how each ranks" gives a specific resource, the basis of competition (shared searches), and the payload (shared count, rank). It is immediately distinguishable from sibling retrieval tools like amazon_get_product or amazon_get_sellers.

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

Usage Guidelines5/5

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

The description has explicit "Use when" phrasings tied to real user intents and an explicit "Not for" clause naming two alternatives: amazon_search_products for a single search's results and seo_get_serp_competitors for web competitors. The routing decision requires no inference.

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