Check Drive File Public Access

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds that the search is performed by file name rather than ID, but it does not disclose additional behavioral nuance such as what counts as 'public link sharing', how the user email is used, or whether only the first match is evaluated. No contradiction with annotations exists.

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, front-loaded sentence with no filler. It communicates the essential action and outcome immediately, and every word contributes to the tool's purpose.

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 strong annotations, 100% schema coverage, and the presence of an output schema, the description covers the core intent well. The only notable gap is the potential ambiguity around what exactly qualifies as 'public link sharing' and whether the tool returns a simple boolean or detailed sharing information, but the output schema likely addresses the return format.

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%, including a notably detailed explanation of the drive_id parameter and its effect on the underlying files.list call. The description itself adds no new parameter-level meaning beyond restating that the tool searches by file name and inspects public link sharing, so the schema carries the load.

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 states a specific verb and resource: 'Searches for a file by name and checks if it has public link sharing enabled.' This clearly distinguishes it from siblings like get_drive_file_permissions or get_drive_shareable_link, since the focus is specifically on detecting public link sharing rather than listing permissions or retrieving links.

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 the usage context: use this tool when you need to verify whether a file is publicly shareable via link. However, it does not explicitly state when not to use it or name alternatives such as get_drive_file_permissions or get_drive_shareable_link, leaving the routing decision to the agent's inference.

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