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

No annotations exist, so the description must disclose behavioral traits. It mentions 'lieferbare' (deliverable) as a filter, but lacks details about result count, pagination, response format, or any side effects. The algorithmic hints ('same manufacturer, top-seller') are helpful but insufficient.

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?

The description is a single sentence of 8 words, very concise with no filler. However, it omits important details like usage context, which would add needed value without losing conciseness.

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 tool with one parameter and no output schema, the description explains the core function and filtering criteria (deliverable, same manufacturer, top-seller). However, it lacks expected return values or example output, which would be beneficial given no output schema.

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 100%. The description does not add meaning beyond the schema's 'Anker-Artikel-ID.' since it only paraphrases the parameter purpose. 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?

The description 'Similar, deliverable products to an article (same manufacturer, top-seller)' clearly specifies the verb (get similar products) and resource (recommendations), distinguishing it from sibling tools like search_products or list_bestsellers by mentioning manufacturer and top-seller filters.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., search_products for broader queries, list_bestsellers for general top sellers). The description does not include exclusions or prerequisites.

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