list_config_downloadclient

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds no behavioral context beyond the word 'Read,' which aligns with the annotations. It does not describe what the response contains or any side effects (which are none). Since annotations cover the main traits, the description adds minimal value, consistent with a baseline score.

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 two short lines: the purpose statement and the endpoint. It is front-loaded with the action and resource, and there is no fluff. It could be slightly more descriptive but is appropriately sized for a simple read-only tool.

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?

Given the tool has no parameters, is read-only, and has an output schema, the description is mostly complete. It could benefit from stating that it returns the global download client configuration (as opposed to per-client settings), but the output schema likely clarifies that. The description is sufficient for an agent to understand what the tool does and call it correctly.

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 tool has zero parameters, so the schema coverage is 100% by definition. The description does not need to explain any parameters, and the baseline for no parameters is 4. The description also includes the endpoint path, which is redundant but harmless. No additional parameter semantics are required.

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 a clear verb ('Read') and resource ('DownloadClientConfig'), making the tool's purpose obvious. It is not a tautology and is distinct from sibling list tools like list_downloadclient (which lists clients) and get_config_downloadclient_by_id (which retrieves a specific config by ID). However, it does not explicitly differentiate itself from those siblings, relying on the name and endpoint to imply uniqueness.

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 gives no guidance on when to use this tool versus alternatives. It does not mention that this returns the global download client configuration, nor when one would choose get_config_downloadclient_by_id instead. The only clue is the endpoint, which is not explained. There is no mention of exclusions or prerequisites.

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