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

Annotations already declare readOnlyHint=true and destructiveHint=false, so safety is covered. The description adds real domain behavior beyond that: payouts happen at pickup after inspection via payment link, and payout_sent is always null because the system never records whether a payout was sent. That caveat prevents the agent from misreading a null field as missing data.

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?

Front-loads the field inventory in the first sentence, then uses two short sentences to explain payout mechanics and the null-field caveat. Every sentence earns its place; slightly dense but not padded.

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 parameters, no output schema, and annotations covering the safety profile, the description carries the remaining burden well by listing returned fields and disclosing the payout_sent caveat. Pagination or result ordering is unaddressed, which keeps it from a 5.

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 tool takes zero parameters, so the schema has nothing to document and the baseline is 4. Nothing in the description needs to compensate for parameter gaps.

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?

States a specific resource (orders on the seller's items) and enumerates the returned fields (order number, status, inspection result, payout, pickup window), so an agent knows exactly what this returns. It does not explicitly name the sibling it is not (seller_list_listings, seller_list_offers), so it falls just short of 5.

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 explicit when-to-use or when-not-to-use guidance and no alternatives are named. The purpose implies it is for reviewing one's sales, but the agent must infer that against seller_list_listings and seller_list_offers with no help.

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