download_torrent_file

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

With no annotations, the description must disclose behavioral traits. It only states 'Download the torrent file' without clarifying if the file is returned directly, saved to disk, or requires authentication. The output_dir parameter suggests saving to a directory, but the description omits this behavior.

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 a single sentence with no waste, making it highly concise. However, it could be improved by briefly mentioning the optional output_dir parameter to aid agent understanding without adding much length.

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 2 parameters and an output schema (not shown), the description should provide enough context for correct invocation. It omits any mention of output_dir, does not explain the output schema, and lacks behavioral detail, resulting in significant gaps.

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%, meaning no parameter descriptions exist in the schema. The description adds no meaning beyond the schema: it mentions 'by id' matching torrent_id, but does not explain output_dir or its default behavior. This fails to compensate for the lack of schema documentation.

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 action ('Download the torrent file') and the resource ('for a specific torrent by id'), which distinguishes it from siblings like get_magnet_link and get_torrent. However, it lacks explicit differentiation or scope details, so it is slightly below a perfect score.

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 provides no guidance on when to use this tool versus its siblings (e.g., get_magnet_link, get_torrent). It does not mention prerequisites, context, or alternatives, leaving the agent to infer usage from the action alone.

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