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

With no annotations, the description carries the full burden and does substantial work: it declares the read is of public data, warns that request/proposal text is untrusted peer content to be treated as data rather than instructions, and states twice that selection does not mean payment and never authorizes one. Missing are auth/visibility rules beyond 'public' and error behavior.

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?

Four short sentences, front-loaded with what is returned, followed by the safety caveats. No filler; each sentence adds a distinct constraint.

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?

The description enumerates the return payload (request, proposals, checkout handoff) and covers the key safety semantics for a read tool with no annotations and no output schema. The only real gap is the undocumented requestId parameter.

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 0% and the single required parameter requestId (uuid) is never mentioned in the description — no format, source, or lookup guidance. The agent must infer it from the property name alone.

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: read a buyer request together with its merchant proposals and selected checkout handoff. This distinguishes it from list_buyer_requests by scope (single request vs list), though it never names a sibling 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?

The description only implies when to use it — after a request exists and possibly after a selection — without naming alternatives such as list_buyer_requests or resolve_latest_merchant_offer, and without stating preconditions beyond the implicit requestId.

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