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

The description adds context that the catalog is a parody and products are fake, which is important for setting expectations. However, without annotations, it does not mention other behavior such as read-only nature, result limits, or any side effects, leaving gaps.

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 compact two-sentence text that immediately conveys the action and output with no unnecessary words. It is well-structured and front-loaded.

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?

Given the tool's simplicity, the description covers the core search function but misses important details such as category usage and any usage notes. With no annotations or output schema, the description is only minimally complete for making an informed decision.

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 provides a description for 'query' but not for 'category', despite it being an enum. The tool description does not explain how category should be used, leaving the filter parameter ambiguous. Thus, the description adds no meaningful parameter semantics 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?

The description clearly states the tool searches the dopamine catalog and returns fake products. This distinguishes it from siblings like buy, get_product, and track_order with a specific verb and resource.

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 guidance on when to use this tool versus alternatives. The description does not mention that search_products is appropriate for discovering products before buying, nor does it exclude using it for other purposes.

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