seller_profile

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It names the source URL pattern, which is useful, but doesn't disclose whether the profile exists for all sellers, what happens when the seller ID is invalid or the profile is unavailable, latency, or whether it requires authorization.

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 single focused sentence with a helpful concrete URL example. It's tight and efficient with no filler, earning its space by anchoring the tool to its data source.

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 no output schema and no annotations, the description should reveal more about return structure and behavior. It identifies the data source and core purpose adequately for a simple lookup tool, but doesn't specify typical return fields, error handling for unknown seller IDs, or special cases, leaving the agent to guess at some aspects.

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 schema already documents all four parameters well. The description itself adds little beyond what the schema provides—it names the seller_id in the URL example but doesn't elaborate on fields projection behavior or country/language interactions beyond what the schema states.

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?

Description clearly states it gets Amazon Seller profile details from the seller profile page, with a concrete example URL showing the source. It uses a specific verb+resource (Get seller profile details) and is distinguishable from siblings like influencer_profile and seller_products, though it doesn't explicitly name those alternatives.

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 implies usage is for reading a seller's public profile via their seller ID but provides no explicit guidance on when to use this vs siblings like seller_products or seller_reviews. No when-not-to-use or alternative tool recommendations are given.

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