run_newegg_sellers

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

No annotations are provided, so the description must carry the behavioral burden. It usefully discloses a cost trait ('Flat 5 points per successful run') and lists returned fields, implying a read-only operation, but it omits authentication requirements, rate limits, error behavior, and pagination or reliability details.

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?

Two sentences with zero waste: the first front-loads the action, resource, input form, and returned fields; the second adds the cost trait. Every clause earns its place.

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?

For a simple one-parameter read tool with no output schema and no annotations, the description covers purpose, accepted input, returned attributes, and cost. It is nearly self-sufficient, with only auth and rate-limit context missing to reach full completeness.

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% and the single parameter is already fully documented with an example ('BioStar'). The description repeats 'store key or URL' but adds no new meaning beyond what the schema provides, so the baseline of 3 applies.

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 names a specific verb and resource: 'Get one Newegg marketplace seller store', and clarifies scope with a list of returned attributes. It differentiates naturally from sibling tools like run_newegg_sellers_products by emphasizing a single seller store rather than products, but it does not explicitly name or contrast with any alternative.

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 states what the tool retrieves and the accepted input form, but gives no when-to-use guidance, no conditions for choosing it over alternatives such as run_search or run_newegg_sellers_products, and no exclusions. Usage must be inferred entirely from the purpose statement.

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