get_downloads_id

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

The description lists many potential error codes, which is a behavioral disclosure regarding failure modes. However, there is no mention of whether the operation is read-only, idempotent, or requires specific permissions. The error codes partially compensate for missing annotations, but the burden is high without annotations.

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 very concise: one sentence plus a list of error codes. There is no fluff, and the error codes are structured. However, the error code list dominates and could be considered verbose, but it's still helpful and not excessive.

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 one parameter and an output schema, the description covers the basic purpose and error conditions. It does not explain the structure or content of the returned Download task, but the output schema likely provides that. The error code list adds completeness. However, for a simple tool, it is minimally adequate.

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 parameter 'id' has no description in the schema (0% coverage). The description says 'the given id' but does not clarify what the id represents (e.g., format, source). The error codes hint at invalid id scenarios, but explicit semantic guidance is lacking.

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 it returns a Download task by id. The verb 'Returns' and the resource 'Download task' make the purpose clear. While it doesn't explicitly distinguish from siblings, the name and description imply it retrieves a specific task, which is distinct from other get_downloads_* tools that retrieve lists or configurations.

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?

No guidance is provided on when to use this tool versus alternatives like get_downloads (to list all tasks) or other get_downloads_* tools. The description lacks context on when to use this specific id-based retrieval, which is a missed opportunity for differentiation.

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