sonarr_get_config_ui_by_id

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

The readOnlyHint annotation already conveys the safety profile, so the description doesn't need to repeat that. It adds minimal behavior context—'single' suggests a single object return—but does not describe output format, errors, or other traits. It does not contradict annotations.

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 one short, front-loaded sentence. Every word adds value, with no filler or redundancy.

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 simple fetch-by-id operation with an output schema and read-only annotation, the description is nearly complete. A brief mention of the corresponding list operation (`sonarr_get_config_ui`) or a note about what a 'UI config' represents could enhance context, but the current text is adequate for selecting and invoking the tool.

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 covers the `id` parameter as an integer, but with 0% description coverage the description must clarify its meaning. 'By id' indicates the parameter is the UI config identifier, which is helpful, but it does not elaborate on allowed values or relationship to other config resources. This is minimal but sufficient for a single-parameter getter.

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 specific verb ('Fetch') and resource ('UI config') with scope ('single ... by id'), clearly distinguishing it from the list-all sibling `sonarr_get_config_ui`. It accurately conveys the tool's function at a glance.

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 implies usage when a specific UI config is needed, but provides no explicit when-to-use guidance or mention of alternatives. It relies on the tool name to signal that this is the by-id variant, so the guidance is implicit rather than stated.

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