get_product_by_id

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

With no annotations, the description is the sole source of behavioral information. 'Get details' implies a read-only operation, but it does not disclose behavior for missing IDs, error handling, permissions, or return format. The output schema covers return values, but the description adds limited transparency beyond the basic action.

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 very concise, with a front-loaded purpose statement and no extra filler. However, the 'Args' section redundantly repeats the schema, which slightly reduces efficiency. Still, it remains appropriately small.

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 get-by-id tool, the description is mostly adequate, especially with an output schema present. However, it omits important context such as error behavior, permissions, and explicitly clarifies when to use this tool versus the plural 'get_products'. Given the lack of annotations, this leaves notable gaps.

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?

The schema has 0% description coverage, so the description must compensate. It repeats the parameter name and a trivial description ('product_id: The product ID') that essentially mirrors the schema title 'Product Id'. No additional meaning, constraints, or formats are provided, so the compensation is minimal.

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 clearly states the tool retrieves details of a specific product, using a specific verb ('Get') and resource ('product'). It is distinguishable from the sibling 'get_products' by the qualifier 'specific', but it does not explicitly mention the alternative, so it falls short of a perfect score.

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 provides no guidance on when to use this tool versus alternatives like 'get_products' or 'get_ticket_by_id'. It lacks any context for selecting this tool over others, offering only a straightforward retrieval statement.

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