doc2x_download_url_to_file

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions that the file 'will be overwritten if it exists,' which is a critical behavioral trait not covered elsewhere. However, it doesn't address other aspects like error handling, network timeouts, or authentication needs, which are important for a download operation.

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, efficient sentence that front-loads the core action ('Download a Doc2x-provided URL') and includes essential details without waste. Every word contributes to understanding the tool's function, making it highly concise and well-structured.

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 complexity (a download operation with 2 parameters), no annotations, and no output schema, the description is moderately complete. It covers the basic purpose and key behavior (overwriting), but lacks details on return values, error cases, or performance considerations, which could aid an AI agent in robust usage.

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 100%, so the input schema already fully documents the parameters (url and output_path). The description adds minimal value by hinting at the URL source ('from doc2x_convert_export_result') and the overwrite behavior, but this doesn't significantly enhance the parameter semantics beyond the schema.

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') and the resource ('a Doc2x-provided URL to a local file path'), making the purpose evident. However, it doesn't explicitly differentiate this tool from its siblings (e.g., doc2x_materialize_convert_zip might also handle file outputs), which prevents 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 implies usage by referencing a specific sibling tool ('doc2x_convert_export_result') as a source for the URL, providing some context. However, it lacks explicit guidance on when to use this tool versus alternatives (e.g., other download or file-handling tools) or any prerequisites, leaving room for ambiguity.

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