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

No annotations are provided, so the description carries the full burden, and it does disclose the returned data surface plus an important trust caveat: the description field is untrusted seller-authored text. It stops short of covering auth needs, rate limits, or not-found/error behavior, which are relevant for a wallet-and-settlement-bearing read.

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?

Two tight sentences with zero filler; the returned-fields list comes first and the security caveat is appended as a separate, front-loaded warning. Nothing is repeated from the name or schema.

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?

With no output schema, the description correctly compensates by naming the payload fields, and it adds a trust warning for seller-authored content. It is close to complete for a one-parameter read tool, missing only failure behavior (invalid or unknown slugOrId) and any access requirements.

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?

Only one parameter exists and schema coverage is 100% ('Service slug or UUID'), so the schema already fully documents it. The description adds no extra semantics about the identifier (e.g. resolution order between slug and UUID), which is the baseline-3 outcome when the schema does the heavy lifting.

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?

States a specific verb and resource ('Get the full specification of a service') and enumerates what that specification contains: description, price, delivery time, seller wallet, settlement terms. It is clear what the tool returns, though it does not explicitly position itself against siblings like search_services or compare_services.

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 statement of when to use this tool versus alternatives, and no prerequisites (e.g. that you need an existing slug/UUID, or when to reach for search_services first). Usage is only inferable from the single-parameter schema, not from the description text.

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