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

Without annotations, the description must carry the disclosure burden. It does disclose that the report is deep, cited, and pay-per-use at 200 USDC on Base, which is useful. It does not describe the output format or mention that the schema-required input is actually presented as optional.

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 compact and front-loads the report type and topic before the use case and pricing. It wastes little space, though the 'x402' pricing bracket is presented as clutter and 'optional' is ambiguous.

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 one-parameter report tool with no output schema, the description provides the core report topic, depth, citation, audience, scope semantics, and payment. It falls short on the required-vs-optional input inconsistency and does not clarify the expected output format or how to request a scope.

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's input description ('service input') is generic, so the tool's phrase 'input=optional scope' adds semantic meaning on top of the 100% coverage. However, that phrase conflicts with the schema marking input as required, which can confuse an agent about what to pass.

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 that the tool produces an industry report on Enterprise AI adoption that is deep and cited, with a clear B2B enterprise-leader audience. This distinguishes it from the many report siblings by topic, though it lacks an explicit action verb.

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?

It signals intended use ('enterprise leaders build their AI roadmap with evidence') and says input is an optional scope, but it never explicitly says when not to use it or which sibling report tool to prefer. There is enough implied context, but no exclusions or alternatives are given.

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