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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the execution cost of $0.25 via x402 Base USDC, which is a key behavioral trait, and notes that it inspects a 'real business', implying external data access. However, it does not disclose whether the operation is read-only, whether it has side effects, rate limits, or error conditions. While it adds some transparency, it leaves significant gaps for a tool that appears to make a paid external call.

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?

The description is two sentences with no filler. It front-loads the core purpose (inspect, estimate, return) and then adds the critical cost detail. Every word earns its place, and it is well-structured for quick scanning.

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?

Despite a clear purpose, the description is incomplete for a tool with 8 parameters and no output schema. It does not explain what the return value looks like (beyond 'recommended next commercial action'), how parameters relate to the computation, or any operational details such as data source requirements or failure modes. The cost mention is useful, but the description leaves too much for the agent to infer about how to correctly call the tool.

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?

The schema has 0% description coverage, and the description provides no parameter-level guidance whatsoever. It does not explain the meaning, format, or expected values for any of the 8 parameters, including required ones like industry, missedCallsPerWeek, and followUpMethod. The enums are self-explanatory by their names, but the numeric parameters like averageJobValue and estimatedRecoveryRate have no hints about their significance. The description does not compensate for the schema's lack of descriptions, leaving the agent to guess from parameter names alone.

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 description clearly states the tool's function: inspecting a real business for missed-call revenue leakage, estimating recoverable revenue, and returning a recommended action. It is specific with a verb and resource, and not a tautology of the title. Since there are no sibling tools, there is no need for differentiation, but the description is unambiguous about what it accomplishes.

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?

The description implies usage whenever one wants to analyze revenue opportunities, but it does not provide explicit guidance on when to use this tool versus alternatives (there are none listed). It also does not mention prerequisites or conditions such as needing specific business data or when not to use it. The purpose is clear enough that an agent would infer usage, but explicit guidance is absent.

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