radarr_get_config_ui_by_id

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

The description aligns with the readOnlyHint annotation (read-only 'Fetch'), and 'single' hints at the return shape. However, it adds no additional behavioral context beyond the annotation, such as error behavior, required permissions, or what the resource represents. With annotations present, this is a neutral score.

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 concise sentence with no wasted words. It could be slightly more informative (e.g., 'UI configuration'), but it is appropriately short for a simple get-by-id tool.

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 (one parameter, readOnlyHint, and an output schema), the description is minimally sufficient. However, 'ui' is ambiguous without the tool name context, and there is no mention of what the resource actually is or when it should be used. It is adequate for a trivial operation but lacks enrichment.

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 schema has one integer 'id' parameter with no description, and schema description coverage is 0%. The description minimally clarifies that 'id' selects the specific 'ui' resource, but this is largely redundant with the tool name. For a single trivial parameter, this is acceptable but not enriching.

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 a clear verb ('Fetch'), specifies the resource ('ui'), and indicates scope ('single ... by id'), which distinguishes it from the sibling radarr_get_config_ui (presumably lists multiple). However, it omits the 'config' context that the tool name provides, so it's not fully explicit.

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 like radarr_get_config_ui or other get_config_*_by_id tools. There are no exclusions, prerequisites, or mentions of alternative tools, leaving the usage context entirely to the agent's inference.

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