sonarr_get_config_host_by_id

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

The description simply restates the tool's action without adding behavioral context beyond the readOnlyHint annotation. It does not disclose what happens if the id does not exist, any error behavior, or additional constraints. The description is consistent with the annotation but contributes no new safety or behavioral 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?

The description is a single, well-structured sentence with the verb front-loaded. It is concise and every word is relevant, but it is slightly under-specified, which prevents a perfect score.

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 get-by-id operation with a single required parameter and an output schema, the description provides the core action. However, it lacks any guidance on when to use this tool in the broader config-tool family, and offers no distinction from other config getters. This makes it minimally viable but not fully self-sufficient.

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?

Schema description coverage is 0%, so the description must compensate. It only says 'by id', which adds minimal meaning to the schema's 'id' integer field. It does not clarify the id's purpose, source, or any validation constraints, leaving the agent to infer from the tool name and context.

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 ('a single host config') with explicit scoping ('by id'). This clearly distinguishes it from sibling tools like sonarr_get_config_host or sonarr_update_config_host, and aligns perfectly with the tool name.

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 provides no guidance on when to use this tool versus alternatives. It does not mention any preconditions, exclusions, or the relationship to other config-related tools (e.g., sonarr_get_config_host). The only hint is the 'by id' phrase, which is not elaborated.

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