TDQS

B3.4/5.0

Behavior3/5

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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description adds real value beyond that by disclosing the cost ($0.02 USDC) and the shape of the response (56 fields including algorithm, as_of). It stops short of saying how payment is settled, whether results are cached, or what happens on an unknown service.

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?

It is short and front-loads the core question, which is good. The structure is a run-on of three clipped fragments separated by a semicolon and stray punctuation ('?.', lowercase 'use'), which reads as notes rather than a specification and slightly obscures the cost and return-value facts.

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 an output schema present, the description does not need to enumerate the 56 fields, and its mention of algorithm/as_of is a helpful pointer rather than padding. Annotations cover safety, and cost is disclosed. The remaining gap is input selection — nothing tells the agent whether to pass a URL, a service name, or both.

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%, so both parameters are documented in the schema, and the description adds nothing about which of url or service_name drives the lookup or how they interact when both are null (both are optional). Baseline 3 is appropriate when the schema carries the load, but the boilerplate schema text ('See the schema for its type and whether it is required') leaves the description with an opportunity it does not take.

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 opening question ('Is this listed service alive, honest and fairly priced?') gives a concrete verdict target and three evaluation axes, and it explicitly names the sibling it is not (assess_endpoint_verdict). 'Listed service' is left undefined, which keeps it slightly short of a fully specific verb+resource statement.

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?

It supplies one routing rule — prefer this over `assess_endpoint_verdict` when you want a verdict specifically — which is genuinely useful. But there is no guidance on when the tool is inappropriate, what a 'listed service' prerequisite means, or whether url vs service_name should be supplied; usage is only partially implied.

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