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

With no annotations, the description carries the full behavioral burden and fails it: it discloses no return content, no execution semantics, no permissions or side effects. Instead it advertises 'step-by-step instructions and a 30-day support promise,' which is sales copy about the product bundle, not information about what invoking the tool does.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Three short sentences, but they are front-loaded with a wrong-domain claim and padded with purchase-oriented promises ('30-day support promise') that earn no place in a tool definition. Brevity here reflects under-specification rather than efficiency.

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

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

For a zero-annotation, no-output-schema tool, the description should explain what the agent gets back and how the workflow artifact is produced; it says nothing about outputs or behavior. Naming the 'kaoyan retest coach' domain is the only substantive content, which is not enough for an agent to call this confidently.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% with a single optional 'query' parameter that the schema already documents as 'Optional user query to scope the analysis.' The description adds no syntax, format, or example for that parameter, so the baseline 3 applies since the schema does all the work.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The name and one clause ('generate a ready-to-use kaoyan retest coach workflow') point at exam-retest coaching, but the description opens by declaring itself an 'AI-powered restaurant & brand intelligence pack,' which contradicts the tool name and misdirects the agent. The remaining sentences describe the commercial packaging of a prompt kit rather than what the tool actually does, so the resource and action are only partially recoverable.

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

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

There is no when-to-use guidance, no when-not-to-use guidance, and no mention of any alternative among the hundreds of sibling tools. 'No prompt engineering needed' is marketing reassurance, not invocation guidance, leaving the agent with nothing to route on.

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