list_downloadclient

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

Annotations already declare readOnly=true, idempotent=true, destructive=false, and the description adds no behavioral context beyond restating read-only intent and the endpoint. Pagination, response shape, or scope of the list are not mentioned, so it provides little beyond structured metadata.

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 short lines, no filler, with the operation statement front-loaded before the endpoint. Every phrase 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 zero-parameter list tool with an output schema and full safety annotations, the description is almost sufficient. It would be more complete if it explicitly said it returns all download clients rather than using the ambiguous singular phrase, but the endpoint and name make the intended call clear.

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 has zero parameters and the schema already documents that completely (100% coverage). The description is not required to explain parameters, and it adds no misleading parameter information.

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 clear verb+resource ('Read DownloadClient') and gives the HTTP endpoint, so an agent can tell it is a read operation on download clients. However, it doesn't explicitly say 'list all' or distinguish itself from get_downloadclient_by_id, so it stops short of full sibling differentiation.

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?

No guidance is provided about when to call this tool versus list_downloadclient_schema, get_downloadclient_by_id, or the create/update/delete siblings. The list_ naming and GET path imply read usage, but the description never states it.

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