get_downloadclient_by_id

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

The annotations already declare readOnlyHint, idempotentHint, and non-destructive behavior. The description's 'Read' and 'GET' are consistent with those annotations and add path-level context, but they do not reveal additional behavioral traits such as error behavior or authorization requirements.

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 three terse lines with no filler. The core action is front-loaded in 'Read DownloadClient,' followed by the endpoint and argument, making it easy to scan.

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 single-parameter read operation, the annotations cover safety and the output schema covers the return shape. However, the description lacks sibling differentiation and usage context, so the agent must infer selection criteria from the tool name alone.

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 for the single id parameter. It only labels id as a path parameter, without explaining that it identifies the specific DownloadClient to fetch, how it relates to the response, or how the id can be obtained.

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 states 'Read DownloadClient' and gives the HTTP GET endpoint, clearly identifying the verb and resource. It does not explicitly differentiate it from sibling tools like list_downloadclient or get_config_downloadclient_by_id, but the name and path make the target unambiguous.

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?

There is no guidance about when to use this tool versus listing download clients or fetching other by-id resources. The description only restates the endpoint and argument, leaving tool selection to inference from the name.

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