wget_file

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

No annotations are provided, so the description carries the full behavioral disclosure burden. "Download from URL" implies a network fetch and likely a file write to the required path, but it does not state whether existing files are overwritten, how certificates are handled, or what authentication may be needed. It gives only the most basic implication of 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 single three-word phrase is concise, but it is under-specified rather than appropriately sized for a tool with three parameters and no annotations. It does not front-load any meaningful context beyond the bare action. The structure is too sparse to be helpful.

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 three parameters at 0% schema description coverage, no annotations, and no output schema, the description is completely inadequate. It does not explain the required path argument, the optional certificate flag, or the expected result. An agent would need to infer nearly everything from the tool name alone.

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% for all three parameters (url, path, ignoreCertificate). The description mentions "URL" but only repeats the obvious url parameter name, and it says nothing about the required destination path or the ignoreCertificate option. With low coverage, the description fails to compensate for missing parameter semantics.

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 states a verb and a source ("Download from URL"), so the agent knows it is a network retrieval operation. However, it does not clarify what is retrieved (file, page, content), where it is stored, or how it differs from the sibling tool download_file. This makes the purpose only minimally viable.

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?

There is no guidance on when to use this tool instead of alternatives like download_file, get_file_content, or get_website. The description provides no context about required permissions, destination behavior, or environmental conditions. The agent receives no routing information beyond the bare action.

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