get_downloadclient_by_id

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

Annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior. The description adds no behavioral context beyond restating the GET endpoint and path parameter; it does not mention return format, errors, auth, or side effects.

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 compact and front-loaded: the operation is stated first, followed by the concrete endpoint and argument note. There is no filler or redundant verbiage, though the Args section is fairly minimal.

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 read-by-id tool with one path parameter, a detailed output schema, and safety annotations, the description provides enough to invoke the tool correctly. It lacks richer context such as when to prefer this over related tools, but that gap is minor given the simplicity.

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?

With 0% schema description coverage, the description does compensate minimally by identifying 'id' as a path parameter. However, it does not explain the meaning of the ID beyond what the tool name and schema already imply, nor does it add format or constraint details.

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 clearly states 'Read DownloadClient' and gives the exact GET path with an {id} placeholder, so the agent knows it retrieves a single DownloadClient resource by ID. This distinguishes it from sibling list and update tools for the same entity.

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 GET-by-id pattern implies usage for fetching one DownloadClient, but the description does not explicitly state when to use this tool versus alternatives such as list_downloadclient or get_config_downloadclient_by_id. There are no clear exclusions or alternative routing guidance.

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