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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, so safety is covered without the description. The description does add one useful behavioral expectation: that the specification set differs by product category (car seats vs strollers vs toys), which prepares the agent for heterogeneous output. It says nothing about error behavior for invalid IDs or whether missing specs are returned empty.

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 sentences with no padding: the core action first, then the category-dependent caveat. Efficient and front-loaded, though the parenthetical field list is somewhat long for the value it adds.

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?

With only one required parameter, full schema description coverage, an output schema, and annotations covering the safety profile, nearly everything an agent needs is present. The only shortfall is absent guidance on how this differs from related spec/detail tools.

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%, so the single parameter is documented in the schema, giving a baseline of 3. The schema's own wording ('Picture ID proizvoda') is ambiguous, and the description only indirectly clarifies that the identifier refers to a product by referring to 'proizvoda', so no real meaning is added beyond the 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 ('Dohvati tehničke specifikacije proizvoda') and enumerates the returned fields (Brand, Težina djeteta, Dob, Visina, Standard, Dimenzije). However it never distinguishes itself from close siblings like get_product_details or get_sizes, which an agent could easily confuse with it.

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 statement of when to choose this tool over get_product_details, get_sizes, or get_categories. The only context given is that spec content varies by category, which describes output shape rather than tool selection.

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