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 states that the copy 'maintains all formatting and content from the original file,' which is useful context. However, it lacks critical details such as permission requirements, rate limits, error handling, or whether the operation is idempotent. For a mutation tool without annotations, this is insufficient.

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 concise and well-structured with two sentences: the first states the purpose, and the second adds details about the copy's behavior. There is no wasted text, and it is front-loaded with the core action. A minor deduction for not being maximally efficient, but it is clear and to the point.

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 that there is an output schema (not provided in details but indicated as true), the description does not need to explain return values. However, for a mutation tool with no annotations and multiple parameters, the description could provide more context on prerequisites or side effects. It is adequate but has clear gaps in behavioral transparency and usage guidelines.

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?

The input schema has 100% description coverage, so the schema already documents all parameters thoroughly. The description adds minimal value by mentioning 'optional new name' and 'new location,' but these are already covered in the schema. Baseline 3 is appropriate as the schema does the heavy lifting.

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's purpose: 'Creates a copy of an existing Google Drive file.' It specifies the verb ('creates a copy') and resource ('Google Drive file'), making the action unambiguous. However, it does not explicitly differentiate from sibling tools like 'copy_drive_folder' or 'create_drive_file', which is why it scores 4 instead of 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?

The description provides no guidance on when to use this tool versus alternatives. It mentions copying a 'template document' but does not clarify if this is specific to templates or any file, nor does it reference sibling tools like 'copy_drive_folder' for folders or 'create_drive_file' for new files. This lack of context leaves usage unclear.

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