Copy Drive File

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

Annotations already indicate mutation (readOnlyHint=false) and non-destructiveness (destructiveHint=false). The description adds that formatting is maintained, which is useful. However, it does not disclose side effects, authorization needs beyond the email param, or what happens if parent_folder_id is invalid.

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 brief, front-loaded, and efficient. Three sentences provide all necessary information without redundancy.

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's straightforward purpose, complete input schema, and annotations, the description is mostly complete. The presence of an output schema likely covers return values. Minor gap: no explicit comparison to sibling tools like create_file.

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?

With 100% schema description coverage, the description adds no new parameter semantics. The schema already fully explains each parameter, including defaults and nullability.

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 action (creates a copy), resource (Google Drive file), and key behaviors (new location, optional new name, maintains formatting). It implicitly distinguishes from sibling tools like create_file (creating from scratch) or get_file_metadata (reading).

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 copying template documents but does not explicitly state when to use this tool versus alternatives like create_file or download_file_content. No prerequisites, when-not-to-use, or exclusions are provided.

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