TDQS

B3.2/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds the computation model (ad-equivalent spend via clicks x CPC) but nothing about rate limits, auth, or edge cases, so the incremental value is modest.

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 first sentence is well front-loaded and dense with useful detail. The second sentence is a promotional link to an external site, which is waste for an agent deciding how to invoke the tool.

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?

With full schema coverage and an output schema present, the description need not explain return values; it adequately conveys what is computed. It is largely complete for a deterministic, four-parameter calculator.

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 every parameter (organicClicks, avgCpc, brandedSharePct, currency) is already documented, and the description names none of them. The mention of 'clicks x CPC' and the non-branded split loosely maps to the inputs but adds little beyond the schema.

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?

It names a specific verb and resource ('Value organic search traffic'), gives the exact formula ('clicks x CPC'), and clarifies the branded/non-branded split. No sibling is named, so it doesn't explicitly route against the many other calculator tools, but the resource and formula make it distinctive.

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?

The description never states when to use this tool versus alternatives such as google_search_impression_share_value_estimator or ppc_click_volume_predictor. Usage context is only implied by the tool's domain.

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