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

With no annotations provided, the description must carry the full burden of behavioral disclosure. It states that results are ranked by rating and include pricing, rating, and links, which is useful. However, it does not disclose default behavior when no filters are given, whether pagination exists, or any rate limits. It is adequate but not exhaustive.

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 two sentences, front-loaded with the primary purpose and result format, then a pointer to get_tool. No wasted words, highly 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 explains the output includes a ranked list with pricing, rating, and links, and the schema covers all parameters. It lacks details on default limits, behavior when no filters are applied, and how multiple filters combine, but for a search tool with a clear schema, this is reasonably complete.

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 all parameters have descriptions in the schema. The description does not add additional meaning to parameters, only refers to 'given filters' generically. Thus it meets the baseline for schema coverage but does not go beyond.

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 it searches and filters the tool catalogue, returns a ranked list with specific fields (pricing, rating, links), and explicitly distinguishes itself from get_tool which provides full detail. This gives an agent a precise understanding of the tool's function and differentiates it from a sibling.

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 explicitly mentions get_tool as the alternative for full detail, providing clear guidance on when to use this tool for search/filter versus that for details. However, it does not mention other siblings like compare_tools or recommend_tool, so the guidance is partial but sufficient for the primary alternative.

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