Pull a remote file

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

With no annotations, the description carries the full burden but only hints that the file lands on the remote server. It does not disclose overwrite behavior, default background vs. foreground execution, permission/auth requirements implied by clientKey/applicationKey, or any side effects of a 10-parameter mutation.

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?

A single front-loaded sentence with no waste. It is efficient but borders on under-specification given the tool's complexity.

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?

For a 10-parameter, no-annotation, no-output-schema tool, one sentence is far too thin. It leaves the agent without enough context to pick correct panel/auth options or predict the outcome of the download.

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 only 60%, so several parameters (url, server, filename, directory) rely on name alone. The description adds no meaning about how directory/filename interact, what 'server' identifies, or how the auth override params behave, failing to compensate for the coverage gap.

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 specific verb and resource ('Download a remote URL') and clarifies the destination is 'onto the server', which distinguishes it from a local download. It does not, however, differentiate itself from siblings like files_download_url or files_upload_url.

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 instead of files_download_url, files_upload_url, or files_write, nor on prerequisites such as panel selection or authentication. The agent must infer usage entirely from the name and schema.

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