radarr_get_config_downloadclient

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

The readOnlyHint annotation already declares the tool is read-only, and 'List' aligns with that. However, the description adds no additional behavioral context such as return format, pagination, or configuration-specific details, offering minimal value beyond the annotation.

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 extremely concise but under-specified. It is a fragment ('List downloadclient.') that omits critical differentiation and usage context, which is not true conciseness but rather insufficient specification.

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 has sibling tools with overlapping names and the description does not address the 'config' aspect or differentiate itself, the description is completely inadequate for an agent to select and invoke this tool correctly. The presence of an output schema does not compensate for the lack of contextual guidance.

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 schema coverage is 100%, so there are no parameter semantics to explain. Per the baseline for 0 params, a score of 4 is appropriate even though the description adds no parameter-related detail.

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 states a clear verb ('List') and resource ('downloadclient'), but lacks scope and does not distinguish from sibling tools like radarr_get_downloadclient or radarr_list_downloadclient. The inclusion of 'config' in the tool name is not reflected, making the purpose somewhat ambiguous.

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 on when to use this tool versus alternatives. With multiple similar sibling tools (e.g., radarr_get_downloadclient, radarr_list_downloadclient), the lack of usage context is a significant gap.

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