batch_download

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

No annotations are provided, so the description carries full burden. It mentions the tool combines extraction and download, and parameters like concurrency and maxFiles suggest behavior, but it does not disclose potential side effects (e.g., creating files, overwriting) or error conditions. For a batch operation, more transparency is warranted, but it adequately conveys the basic function.

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 sentences, front-loading the primary action and including a helpful usage example. Every word contributes: no redundancy, very efficient.

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?

With no output schema, the description could have explained what is returned (e.g., list of downloaded files). It covers parameters adequately but lacks mention of return value or error handling. For a batch tool, slightly incomplete but functional.

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 baseline is 3. The description does not add significant meaning beyond the schema, but it contextualizes the parameters by stating the tool extracts from a container and downloads, which aligns with the parameter roles. No extra value, but no deficiency.

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 extracts resources from a DOM container and downloads them all, specifying it combines extract_resources + download. This differentiates it from siblings like extract_resources and batch_click.

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 usage examples (downloading images from a chat, PDFs from a table), giving clear context. It does not explicitly state when not to use, but the examples imply the intended use case. Alternatives like extract_resources are implied by the combination mention.

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