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

With no annotations, the description carries the transparency burden. It conveys a read-only metadata/pricing role and sets expectations about what it will not answer, though it does not explicitly state read-only behavior, data source, or output shape. The presence of an output schema reduces the need to describe return values.

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 front-loaded with the core purpose and uses examples and exclusions efficiently. The sentence 'This is the pricing tool' is slightly redundant after the opening, but the overall length is reasonable for the scope it covers.

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 no-parameter metadata lookup with an output schema, this description is complete: it states what information is available, gives example queries, and rules out the main misuse cases. An agent has enough context to select and invoke it correctly.

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 tool has zero parameters, so there is no parameter schema to clarify. The description compensates by defining the categories of questions the tool answers, which is all that is needed here.

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 identifies the tool as the service/pricing/discovery metadata source for premises licensing and gives concrete query categories (jurisdiction, workflow, free/paid, x402/payment mode). It distinguishes itself from compliance/blocker checks, though it lacks a direct action verb like 'get' or 'list' and does not name sibling tools explicitly.

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 provides explicit when-to-use guidance: select for jurisdiction, supported workflow, pricing, payment mode, or any cost question. It also gives a clear when-not-to-use exclusion for compliance/blockers and applicant input completeness, but it does not point to a named sibling alternative.

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