Read-onlyIdempotent

Return the FreightUtils pricing page URL with the Pro plan's request limit and monthly price for questions about plans, API limits, or pricing.

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.

TDQS

A4.5/5.0
Behavior5/5

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

Goes well beyond the annotations by disclosing that this is a static local response with no API call, never rate-limited, no account or payment action, and that the user opens the URL in a browser. That is exactly the operational context an agent needs before surfacing a link.

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?

Front-loaded with the action and payload, then cleanly segmented into 'Behavior' and 'Returns' blocks. No sentence is wasted and each label earns its space.

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?

Given a single optional enum param, full annotations, and an output schema, nothing an agent needs is missing. The behavioral disclosures close the remaining gaps even though the output schema already covers return values.

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 the single 'tier' enum is fully documented in the schema, so the description carries little added burden. Mentioning 'the Pro plan' reinforces the only supported tier, but adds no syntax or constraint beyond the schema — baseline 3.

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 the payload details (Pro plan limit and price). The purpose is instantly clear and, since every sibling is a calculator or lookup, an agent can place it without further digging.

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?

Explicitly names the trigger: 'Use when the user asks about FreightUtils plans, pricing or API limits.' It does not name a when-not condition or an alternative tool, but no sibling overlaps with pricing, so context is sufficient.

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