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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds genuine value by disclosing that the response includes prices and settings and by naming the underlying endpoint (GET /finance/products/{id}), but says nothing about not-found behavior or auth requirements.

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, front-loaded with the capability and followed by the endpoint reference. Nothing is redundant or padding.

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 single-record GET with one fully documented required parameter, the description covers purpose, the resource returned, and the API mapping. No output schema exists, and 'prices and settings' gives a partial sense of the return shape, so only minor gaps (error/empty cases) remain.

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% and the single 'id' parameter is documented as 'Record id.' The description adds no format guidance (e.g., whether string or integer ids are preferred despite the anyOf) so it performs at the baseline for a fully documented schema.

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 and resource ('Get one product or service') and clarifies scope with 'one', which implicitly separates it from the sibling kledo_list_products. The added note that it returns prices and settings makes the purpose concrete, though no sibling is named explicitly.

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 singular 'one product' plus a required id implies this is for retrieving a known record rather than browsing, which implicitly routes bulk lookups to kledo_list_products. However, it never states when to use this instead of the list tool, and gives no prerequisites or exclusions.

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