TDQS

B3.1/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds only that the catalog is 'compact' and 'current'; it says nothing about pagination via cursor, result caps, or filtering behavior.

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?

A single short sentence with the core purpose front-loaded and no filler. It is efficient, though its brevity comes at the cost of covering pagination and filter parameters.

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

Completeness2/5

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

For a five-parameter, zero-coverage list tool with no output schema and no annotation detail about returns, the description is too thin: pagination (cursor/limit), the type enum, and the country/in_stock filters go entirely unaddressed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% across five parameters (type, limit, cursor, country, in_stock), and the description explains none of them. 'Compact' loosely hints at a limit and 'current' at inventory filtering, but an agent gets no guidance on the type enum, pagination, or the country/stock filters.

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 gives a concrete verb and resource: 'List a compact catalog of current products and prices.' That is clear and distinguishable from the session/billing-oriented siblings, but it does not name or contrast with any sibling tool.

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 trailing phrase 'before purchasing' implies the intended context (pre-purchase price browsing), so usage is inferable, but there is no explicit when-to-use statement, no exclusions, and no mention of alternatives for purchase or balance checks.

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