A4.1/5.0
Scored across 1 tool
Disambiguation5/5
With only a single tool, there is no possibility of confusion between tools. The tool's purpose is clear and distinct.
Naming Consistency5/5
A single tool name is trivially consistent with itself. No naming pattern issues exist.
Tool Count1/5
The server claims to be an online marketplace for physical products but provides only a search tool. This is an extreme mismatch between scope and tool count; a marketplace requires many more tools for cart, checkout, user management, etc.
Completeness1/5
The tool surface is severely incomplete for a marketplace. Only product search is available, lacking essential operations like adding to cart, placing orders, viewing user profiles, or managing listings.
Available Tools
1 toolsearch_productsAInspect

Use this tool to find products by name, description, or category. Always use this before adding anything to cart.
Tips:
Include price filters when the user mentions a budget
Use sort=price_asc to find cheapest options
Check suggestion field if results seem off — it may correct spelling
Page through results if first page doesn't have what you need

A4.5/5.0
Behavior3/5
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, so description must disclose behavior. It mentions pagination, spelling correction (suggestion field), and hints at result quality checks, but does not explicitly state read-only nature, auth requirements, rate limits, or behavior on no results. Adequate but not comprehensive.
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?
Concise: one core sentence, one usage directive, and three bulleted tips. No unnecessary words. Front-loaded with purpose. Each sentence adds value.
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 no annotations or siblings, and presence of output schema (context signal), the description covers search initiation, pagination, sorting, filtering, and result verification via suggestion field. Enough for an agent to use the tool correctly in most scenarios.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Parameters4/5
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
All 8 parameters have schema descriptions (100% coverage). The description adds value beyond schema by contextualizing their use (e.g., price filters for budget, sort for cheapest, suggestion field for spelling). This helps the agent apply parameters effectively.
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?
Clearly states the tool searches a catalog of 10 million products by name, description, or category. The verb 'Search' and resource 'products catalog' are specific, and the description distinguishes this as a pre-cart search tool, though no siblings are listed.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Usage Guidelines5/5
Does the description explain when to use this tool, when not to, or what alternatives exist?
Explicitly states 'Always use this before adding anything to cart.' Provides actionable tips: use price filters on budget mentions, use sort=price_asc for cheapest, check suggestion field for spelling corrections, and page through results. This fully guides when and how to use.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
