TDQS

A4.2/5.0

Behavior4/5

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

Annotations already declare readOnlyHint, openWorldHint, and idempotentHint, so the safety profile is covered. The description adds valuable behavioral context: radius cap (50 miles), max results (10), distance ordering, live data, and the prerequisite to geocode first. This goes beyond annotations and helps the agent set expectations.

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?

The description is two sentences plus an example, with no wasted words. It front-loads the core purpose, then adds constraints, and finishes with a practical example. Every sentence contributes to understanding 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?

Given the tool's complexity (6 parameters, 2 required) and the presence of an output schema, the description covers the essential behavior, constraints, and usage example. It does not mention error handling or edge cases, but for a read-only tool with strong annotations, this is sufficient.

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 67%, with lat, lng, limit, and radiusMiles described. The description mentions the radius cap and result limit but does not add new meaning to parameters beyond what the schema provides. Since coverage is moderate but not low, the description is not required to compensate heavily; it adds minimal extra value.

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?

The description clearly states the verb 'Find', the resource 'Cyclesite listings', and the specific scope 'within a radius of a UK location (lat/lng)'. It also adds distinguishing constraints like radius cap and return limit, making it distinct from sibling search tools. The example further clarifies the intended use case.

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?

The description provides a concrete example ('used bikes within 25 miles of LE10 0AA') and instructs to geocode the postcode first, implying when this tool is appropriate. However, it does not explicitly mention alternatives or when not to use it, leaving some inference required.

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