A3.8/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so 'Read-only' in the description is a restatement rather than new information. The only added behavioral fact is that the record originates from search_offers; nothing is said about what happens when neither id nor url is supplied, or about lookup failures.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The core sentence is front-loaded and efficient, but the German and English renderings are near-verbatim duplicates, roughly doubling length without adding information. 'Read-only' is tacked on redundantly after annotations already cover it.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

An output schema exists, so return values need not be explained, and all three parameters are documented in the schema. The remaining gap is that no parameter is required, yet the description never states that one of id or url must be provided, nor which takes precedence.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the baseline applies: each parameter (id, url, language with its enum and default/fallback behavior) is already fully documented in the schema. The description only echoes the externalId linkage, adding no format or precedence details beyond it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('looks up a partner offer') plus the exact key used ('by its ID (externalId)'), and names the sibling search_offers as the source of that ID. An agent can distinguish this single-record lookup from search_offers and find_pages without opening any schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description makes the usage context explicit: this is the follow-up step once you have an externalId from search_offers, and a product URL is an alternative entry point. It stops short of an explicit 'do not use this to discover offers – use search_offers instead' exclusion, so it lands at 4 rather than 5.

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