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

With no annotations, the description carries the full burden; it usefully discloses the merchant:work bearer-key scope requirement and the subset of tickets returned (only ones addressed to this merchant). It says nothing about ordering, pagination, caching, or read-only side effects, which leaves real gaps for a list operation.

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?

Three short sentences; the identifying purpose is front-loaded, followed by auth and then return scope. No filler, though 'Seller inbox' is terse to the point of ambiguity about what operation is actually performed.

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?

There is no output schema and no annotations, so the description must convey return shape; it does so at a high level (buyer input, quote/payment/result state) but does not describe ticket fields, ordering, or how `limit` behaves. Adequate minimum, clearly incomplete for a list tool.

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 single parameter is `limit` with a maximum of 50, and schema description coverage is 0% — yet the description never mentions it, so the agent gets no meaning for it beyond the name. The description neither compensates for the coverage gap nor explains default behavior when it is omitted.

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 frames the tool as the seller's inbox and states it returns only tickets addressed to this merchant, including buyer input and quote/payment/result state. That is a clear verb+resource in spirit, though it never uses an explicit verb like 'list' and leans on the 'Seller inbox' metaphor to convey enumeration.

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?

Usage is only implied: the inbox framing suggests checking incoming work, and the 'addressed to this merchant' clause distinguishes it from nothing in particular among the many ticket siblings (get_work_ticket_status, read_work_ticket_result). No explicit when-to-use or when-to-use-instead guidance is given.

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