bookshelf_get_config_downloadclient

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

The annotation readOnlyHint:true already indicates a safe read operation. The description adds no additional behavioral details such as what is returned, whether it returns a single configuration or a list, or any constraints. It simply restates the action without enriching the agent's understanding of side effects or outputs.

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?

The description is a single short sentence, which is concise and without filler. However, it is so brief that it borders on under-specification, lacking any explanatory detail that might help the agent. Still, it does not waste words.

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?

Given the tool's simplicity, the description might be sufficient if there were no siblings, but with many related tools such as bookshelf_list_downloadclient and bookshelf_get_downloadclient, the description fails to provide enough context to disambiguate. The lack of clarification about what 'config downloadclient' means makes the description incomplete for effective tool selection.

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 schema fully covers the parameter surface. The description does not need to explain parameters, and it does not attempt to, which is appropriate.

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 uses the verb 'List' and identifies 'config downloadclient' as the resource, but it does not clarify what this tool lists compared to sibling tools like bookshelf_list_downloadclient or bookshelf_get_downloadclient. The phrase 'config downloadclient' is ambiguous—it could mean the configuration of download clients or a list of download client configurations. This vagueness prevents a clear understanding of the tool's purpose.

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 guidance about when to use this tool instead of alternatives like bookshelf_list_downloadclient or bookshelf_get_config_downloadclient_by_id. The description offers no context for selection, leaving the agent to guess based on the name alone.

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