check_drive_file_public_access

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

The description states it is a read-only check, which is transparent. However, it lacks details on behavior for edge cases (e.g., file not found, multiple matches) and prerequisites like authentication. With no annotations, the description carries the full burden but only partially meets it.

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 extremely concise: one sentence for the purpose and a brief arg/returns section. No unnecessary information, and it is front-loaded.

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 simplicity (2 parameters, no nested objects), the description adequately covers purpose and parameters. However, it lacks usage context relative to siblings and does not fully explain the return value structure, though an output schema exists.

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 description explicitly explains both parameters: user_google_email and file_name, stating their types and roles. Since the input schema has 0% description coverage, the description fully compensates by providing clear semantics.

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 action: it searches for a file by name and checks if public link sharing is enabled. It uses specific verbs and identifies the resource (file), and this is distinct from sibling tools like get_drive_file_permissions or get_drive_shareable_link.

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 provided on when to use this tool versus alternatives. Sibling tools exist for broader permission checks or link retrieval, but the description does not differentiate usage contexts or mention exclusions.

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