List uploads

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint, so the safety profile is covered. The description contributes two extras beyond that: result ordering (newest first) and that each entry carries progress state ('how far each has got') — useful, but the phrasing is vague about what that progress field actually expresses, and pagination is unmentioned.

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?

A single short sentence with the scope and ordering front-loaded and no filler. Every clause carries information, and nothing is buried.

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 and no output schema, the description carries the burden of explaining what comes back, and it does so only sketchily ('how far each has got'). It is adequate for a trivial read, but omits result-set size/pagination and any hint of how this differs from the near-identical sibling 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 tool takes zero parameters, so there is nothing for the description to disambiguate and the baseline of 4 applies. The description correctly implies no filtering or paging arguments are needed.

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 sentence names the resource ('the account's listing uploads') and the ordering ('newest first'), so an agent knows this is a scoped list operation. It does not, however, differentiate itself from the very similar siblings 'upload_listings' and 'get_listing_upload', which is the one thing a reader would most need.

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 when-to-use guidance at all: no mention of when to prefer this over 'upload_listings', when to drill into a single upload via 'get_listing_upload', or any prerequisite such as an authenticated account context. The agent must infer the routing decision from the name alone.

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