Get Drive Shareable Link

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is well covered. The description adds no extra behavioral context beyond the read-only nature already implied by 'Gets' and the annotations, such as whether an existing link is returned or whether additional sharing state is involved.

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?

A single, front-loaded sentence states the exact operation and object with no filler. Every word earns its place, and it is appropriately short for a simple read tool.

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 low complexity, two fully documented parameters, rich annotations, and an available output schema, nothing essential is missing. The description adequately orients an agent toward correct invocation without needing to restate structured information.

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 parameters are already fully documented. The description adds no additional meaning beyond what file_id and user_google_email already convey, so it meets but does not exceed the baseline.

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 uses a specific verb ('Gets') with a specific resource ('the shareable link') and explicitly scopes it to 'a Google Drive file or folder.' This distinguishes it from sibling tools like get_drive_file_download_url and get_drive_file_content without needing to open schemas.

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 intended use is implied: use when you need the shareable link for a Drive item. However, there is no explicit guidance on when to choose this over alternatives such as get_drive_file_download_url or get_drive_file_permissions, and no mention of prerequisites or exclusions.

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