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

Annotations already declare this a safe, closed-world read (readOnlyHint=true, destructiveHint=false, openWorldHint=false), so the safety profile is covered. The description adds essentially no behavioral context beyond that — nothing about what is returned, whether offers can expire, or whether any auth/entitlement is needed to read an offer.

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. It is efficient, though the brevity is part of why parameter and workflow detail is missing.

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-parameter read with no output schema, the definition is minimally viable but leaves the two things an agent most needs — how to source offer_id and what the response looks like — unaddressed.

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% for the single required parameter offer_id, so the description must carry the burden and it does not — it never mentions offer_id, its format, or where to obtain one. An agent is left guessing whether the ID comes from a list call or elsewhere.

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') and resource ('a single specialist service'), and the singular framing implicitly contrasts with the list-style siblings. What exactly an 'offer' contains is described only abstractly as 'machine-readable scope and boundaries', so an agent gets the gist but not a concrete picture of the returned object.

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 guidance on when to call this versus marketplace_list_offers, marketplace_quote, or marketplace_describe, and no prerequisite such as needing an offer_id obtained from a listing call. The agent must infer the workflow entirely.

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