Read-onlyIdempotent

Retrieve the FreightUtils pricing page URL for the Pro plan, including its 50,000 monthly request limit and price, to answer questions about plans, pricing, or API limits.

Instructions

Return the FreightUtils pricing page URL with the Pro plan's request limit (50,000 per month) and price. Use when the user asks about FreightUtils plans, pricing or API limits.

Behavior: static local response — no API call, never rate-limited, no account or payment action; the user opens the URL in a browser.

Returns: url, tier, monthly_limit, monthly_price, currency and note under result.

  5. Addedv2.1.1

TDQS

A4.4/5.0
Behavior5/5

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

Goes well beyond the annotations by disclosing execution behavior: 'static local response — no API call, never rate-limited, no account or payment action; the user opens the URL in a browser.' This tells the agent there is no side effect, no latency, and no auth requirement, which the readOnlyHint/idempotentHint flags alone do not convey.

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?

Two tight paragraphs, with purpose and usage front-loaded and behavior second. The 'Returns:' line partially restates fields already present in the output schema, which is the only real redundancy.

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

Completeness5/5

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

For a trivial single-optional-param read tool with an output schema and rich annotations, nothing an agent needs is missing — it knows when to call, what it does offline, and that no payment or account state changes.

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 there is only one optional, single-value enum parameter, so the schema already carries the load. The description reinforces the 'Pro plan' context but adds no syntax or behavioral detail beyond what the enum documents.

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?

States a specific verb and resource ('Return the FreightUtils pricing page URL') plus exactly what is packaged with it: the Pro plan's request limit and price. This is unmistakably distinct from every sibling, which are all logistics lookups and calculators.

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

Usage Guidelines4/5

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

Gives an explicit trigger: 'Use when the user asks about FreightUtils plans, pricing or API limits.' No when-not guidance or named alternatives are offered, but no plausible alternative tool exists among the siblings for pricing questions, so the routing gap is minimal.

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