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

No annotations are present, so the description must disclose behavior; however, it only restates the tool's function without detailing filter behavior, pagination, or any limitations. It fails to mention how filters combine, default sort, or whether results are trimmed.

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 short sentences that convey the core function without fluff. It lacks depth but is efficiently structured with the verb upfront.

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?

Despite 12 parameters and no output schema, the description does not explain the returned listing structure, how filters interact, or any usage context. It leaves significant gaps for an agent relying solely on this text to invoke the tool correctly.

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 no additional semantic value beyond generic 'various filters' that maps directly to the schema parameters. All parameter meanings are already provided in 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 identifies the tool as a marketplace browser/search with filters, and the mention of 'endpoints, products, and agentic services' differentiates it from type-specific sibling tools like list_agents. While not explicitly naming alternatives, the broad scope provides sufficient purpose clarity.

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?

No explicit guidance is given on when to use this tool versus siblings such as get_listing, get_featured, or list_agents. The description only states browsing and searching, leaving the selection condition implied.

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