bookshelf_list_downloadclient

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

The annotation readOnlyHint: true already communicates that this is a read-only operation, and the description adds no additional behavioral context such as pagination, ordering, or scope. It merely repeats the verb 'list' without extra information.

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?

Although the description is a single short sentence, it is under-specified and redundant with the tool name. It is concise in length but not in informative value, making it closer to under-specification than effective conciseness.

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?

Despite the simple nature of the tool (zero params, readOnly annotation, output schema), the description 'List downloadclient' does not explain what is being listed or whether it returns all items. The output schema mitigates the need for return-value details, but the description still feels incomplete for guiding an agent.

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, so the input schema fully describes the expected inputs. The description adds nothing, but with 0 parameters the baseline is 4 and no parameter documentation is 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 description 'List downloadclient' is essentially a restatement of the tool name 'bookshelf_list_downloadclient' and adds no clarifying detail about what a downloadclient is or what the listing operation provides. It is tautological rather than a meaningful explanation.

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 gives no guidance on when to use this tool versus alternatives such as bookshelf_get_downloadclient, nor does it mention exclusions or context. There is no mention of how this list operation compares to other downloadclient-related or list operations.

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