sonarr_get_config_indexer_by_id

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

The readOnlyHint annotation already indicates the operation is safe, and the description's 'Fetch' is consistent with that. However, it adds no further behavioral context such as error handling, existence requirements, or return format. With annotations covering the safety profile, a neutral score is appropriate.

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, front-loaded sentence that directly states the tool's purpose with no filler. It is appropriately sized for a simple get-by-id operation.

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?

With a single parameter, readOnly annotation, and an output schema, the description is mostly complete for its simplicity. It clearly communicates the core action, though it does not explicitly differentiate from sibling tools or clarify the id's provenance, which is a minor gap.

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%, and the description only restates 'by id' without explaining what the id refers to or how to obtain it. The schema property is labeled 'id' and typed integer, but the description adds no meaning beyond that. The agent is left to guess whether this is a config-specific id or an indexer id.

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 'Fetch a single indexer config by id' clearly states a specific verb (Fetch), resource (indexer config), and scope (by id). It distinguishes from sibling tools like sonarr_list_config_indexer (which lists all configs) and sonarr_get_indexer (which retrieves a different resource).

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 id is known, but provides no explicit guidance on when to use it versus alternatives. No exclusions or alternative tool references are mentioned, leaving the agent to infer from the name and context.

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