operations_copyurl

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 omits important traits such as whether the operation overwrites existing files, authentication requirements for the URL, async behavior, or error handling. Only basic download-and-store is mentioned.

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 concise sentence that front-loads the key operation. It has no redundant information, but a bit more detail (e.g., supported URL types) would improve without harming conciseness.

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 6 parameters, no output schema, and no annotations, the description is insufficiently complete. It does not explain return values, async behavior, or potential pitfalls (e.g., URL accessibility, file naming). More context is needed for reliable invocation.

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 coverage is 100% with all parameters having descriptions. The tool description does not add new meaning beyond the schema; it only rephrases the core function. Since baseline is 3 for full schema coverage, the score is maintained.

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 downloads a public URL and stores it at a remote path. It uses specific verbs ('Copy from URL', 'Downloads') and resource ('public URL', 'remote path'), distinguishing it from siblings like operations_copyfile or operations_uploadfile.

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 for downloading from a public URL but does not explicitly state when to use this tool over alternatives (e.g., operations_copyfile for remote-to-remote copy). No exclusions or comparisons are provided.

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