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

Annotations already declare readOnlyHint and closed-world, so the description's added value is the 'public details' field-scoping and the restriction to 'active' requests — useful constraints beyond the annotations. It does not say what happens for inactive, deleted, or nonexistent ids, nor anything about return shape.

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?

One front-loaded sentence with no filler; every phrase (full, public, one, active, slug or id) carries information.

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 simple single-param read with annotations covering safety, the essentials are present, but with no output schema the description leaves unclear which fields 'full public details' comprises and how missing/inactive requests are surfaced.

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 coverage is 0% for the single 'id' parameter, so the description must compensate — and it does by disclosing that the identifier may be either a slug or an id. It does not specify format constraints or whether ambiguous inputs are rejected.

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 ... buyer request') with scope qualifiers ('full public details', 'one active'). It is distinguishable from search_buyer_requests and create_buyer_request, though it never names those siblings 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?

Usage is only implied: 'one ... by slug or id' signals a single-record lookup as opposed to the sibling search tool, and 'active' hints at a filtering precondition. No explicit when-to-use/when-not or alternative routing is given.

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