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 payment but fails to explain the two-step x402 payment flow (challenge then signature) or any side effects, return behavior, or safety profile. The agent is left unaware of the payment interaction or what happens after invocation.

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 brief and front-loaded with the core purpose in the first sentence. The second sentence provides payment details, which are relevant but not the primary focus. There is minimal waste, though the payment info could arguably be moved elsewhere.

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?

Given the tool has a nested object with no parameter documentation and no output schema, the description is insufficient for an agent to know how to construct the request or interpret results. It lacks details on expected input fields, output format, or the payment challenge flow, making the tool incomplete for autonomous invocation.

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 50% (only paymentSignature has a description), and the tool description adds nothing about the request parameter's structure or expected content. Since request is a nested object with additionalProperties allowed, the agent has no idea what to put inside it. The description does not compensate for this gap.

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 states a specific verb and resource: 'Generates future-use scenarios and infrastructure questions for underused or undervalued land.' This is clear and distinguishes the tool's purpose from generic generation tools. However, it does not explicitly differentiate from siblings like faber_desert_infrastructure, which might have overlapping scope, so it's not a perfect 5.

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?

No guidance is provided on when to use this tool versus alternatives, what the request object should contain, or when not to use it. The description only mentions payment details, leaving the agent without context on how to invoke the tool correctly or route to it.

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