TDQS

A3.6/5.0

Behavior3/5

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

The annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the description carries no burden for safety traits. What it adds is content scope (variants, sizes, colors, availability) rather than behavioral characteristics like rate limits, errors, or authorization requirements. This is adequate but adds no significant behavioral transparency beyond annotations.

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

Conciseness5/5

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

A single sentence with no filler, the action is front-loaded, and the included detail modifiers are concise. Every word contributes to understanding the tool's purpose.

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

Completeness4/5

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

For a one-parameter, read-only tool with an output schema and rich annotations, the description is essentially complete. It doesn't explain when to use it vs alternatives, but that gap is relatively minor for a get-by-ID operation and is somewhat addressed by the schema. Overall, it provides enough for an agent to call it correctly.

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?

The schema description for product_id is complete (100% coverage) and already instructs using the `id` field from search_products or nlweb_ask and not to invent IDs. The tool description provides no additional parameter-level meaning, 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?

The description clearly states the tool retrieves detailed information for a specific product, listing included attributes (variants, sizes, colors, availability). The verb 'Get' and resource 'specific product' are explicit. It does not explicitly distinguish from sibling tools like search_products or search_products_enriched, but the 'specific product' phrasing implies a lookup-by-ID role.

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

Usage Guidelines3/5

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

The description implies usage when a specific product ID is known, but it does not provide explicit guidance on when to use this tool versus alternatives such as search_products or compare_products. The parameter schema adds the hint to use IDs from search_products or nlweb_ask, but the description itself lacks this context.

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