list_downloads

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

No annotations are provided, so the description carries the full burden. It discloses that each download includes a contentUrl for retrieval, which adds value beyond the schema. However, it does not disclose any behavioral traits such as data freshness, pagination behavior, or potential side effects. The description is adequate but not rich.

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 succinct with two sentences. The first sentence covers purpose and filters, and the second adds a key output detail. No unnecessary words – every sentence earns its place.

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 number of parameters (10) and no output schema, the description is fairly complete by stating filtering criteria and a key output field. However, it lacks mention of pagination defaults (limit/offset) and sort behavior, though these are in the schema. The description could be slightly more comprehensive, but it covers the essentials.

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 coverage is 100%, so the description does not need to repeat parameter details. It mentions filtering capabilities, which are already in the schema, and adds the context of contentUrl in the output. This adds marginal value, justifying a baseline score of 3.

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 the tool's purpose: listing downloaded files with optional filtering. It specifies the verb 'List' and the resource 'downloaded files', and distinguishes from siblings like 'get_download' (singular) and 'delete_download'. The mention of specific filter criteria and contentUrl adds precision.

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 by listing available filters, but does not explicitly state when to use this tool versus alternatives. However, given the sibling set, no other listing tool exists, so the context is clear. A brief statement of when not to use (e.g., for a single download) would improve this dimension.

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