Copy Drive file

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only says 'Copy a file, optionally with a new name.' It does not reveal where the copy is created, whether it overwrites existing files, what permissions are needed, or what side effects occur. This is a minimal statement rather than a transparent one.

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 short sentence with no filler, and the core action is front-loaded. It earns conciseness points, though it is so terse that it sacrifices useful context.

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?

The tool is simple and all parameters are documented in the schema, but there is no annotation or output schema to fill gaps. The description omits the copy destination, return value, and any behavioral caveats, making it minimally viable rather than complete.

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 baseline is 3. The description adds no real semantic detail beyond the schema; it loosely maps to the 'name' parameter but does not explain the behavior of fileId or account. This is adequate but not additive.

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 identifies the operation as copying a Drive file, with an optional new name. This is a specific verb and resource, and among the sibling tools it is the only copy operation, so the action is unambiguous. It does not explicitly contrast itself with related tools like upload or update, so it stops short of a 5.

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?

No guidance is given for when to use this tool versus alternatives such as google_drive_upload or google_drive_update. The description does not state prerequisites, destination behavior, or exclusions, leaving the agent to infer appropriate usage.

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