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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered. The description adds that requested related records are embedded via include and names the underlying endpoint, but says nothing about error behavior for bad UUIDs or the shape/size of the embedded payload.

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 short sentences, zero filler; the core behavior comes first and the endpoint is a compact supporting detail.

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 two-parameter read tool with full schema coverage and safety annotations, this is nearly complete; mentioning the "included" payload gives a hint about the response. It stops short of describing how embedded records are keyed or what happens with an unknown UUID, but nothing essential to invoking it is missing.

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 100% — both parameters are documented in the schema, including the include enum and the UUID source hint. The description only restates the include behavior, adding essentially no semantics beyond the schema, so baseline 3 applies.

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 (get/return) and resource (one sales offer) plus the scoping key (UUID), and mentions the include-driven embedding. It doesn't name a sibling tool explicitly, but the singular-vs-list contrast with street_list_sales_offers is clear from the schema reference.

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?

Implies usage: fetch a single offer when you have its UUID (obtained from street_list_sales_offers). There is no explicit when-not guidance or statement about alternatives, but for a simple lookup tool the implied context is unambiguous.

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