drive_list_permissions

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

With no annotations provided, the description carries the burden of behavioral disclosure. It implies a read-only operation but does not detail what permission data is returned, whether inherited permissions are included, access requirements, or pagination. The minimal wording adds little beyond the tool's name.

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, tightly worded sentence with no filler. It is immediately clear and front-loaded with the action and target.

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?

The tool is simple with one parameter and an output schema present, but the description omits any behavioral context such as permission types, filtering, or return format. It is minimally viable but lacks details that would fully orient an agent, especially without annotations.

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 0%, and the description only says 'on a file,' which vaguely references the file_id parameter but doesn't explicitly explain that the parameter identifies the target file. It adds minimal meaning beyond the parameter name and type.

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 ('List') and resource ('sharing permissions') with a clear target ('on a file'). It clearly distinguishes from sibling tools like drive_share_file and drive_delete_permission, though it doesn't explicitly differentiate from drive_list_comments or drive_list_revisions.

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, such as drive_share_file or drive_delete_permission. There are no prerequisites, exclusions, or context about how this differs from other listing tools (e.g., drive_list_comments).

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