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

With no annotations, the description carries the behavioral burden and does disclose useful traits such as Greek/English support and returned fields including price in EUR and stock status. It still omits specifics about search matching, pagination behavior, and whether results are ranked, so it is adequate but incomplete.

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 front-loaded with the core action and then adds relevant store and result context. The second sentence contains some marketing-style product detail that is less essential, but overall the structure is clear and efficient.

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?

The description helps compensate for the lack of an output schema by listing key returned fields. However, for a tool with no annotations, it does not fully explain pagination or result-count behavior, leaving some operational context to the 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%, so the baseline is 3. The description adds meaning beyond the schema by noting that queries work in Greek or English, which directly informs how the 'query' parameter should be constructed.

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 states a specific verb and resource: search the Men Groomer product catalog. It is clear what the tool does, but it does not explicitly distinguish itself from the sibling get_product tool, which likely handles single-product lookups.

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?

Usage is implied by 'Search the ... product catalog,' and the language note helps frame the query. However, there is no explicit guidance on when to use this tool instead of get_product or store_info, and no exclusions are stated.

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