remove_drive_permission

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

With no annotations, the description carries full burden. It discloses the destructive nature (revoking access) and includes a dry_run parameter for preview, which mitigates risk. It also states the return type as a confirmation string.

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 concise with a clear summary followed by a bulleted parameter list. Every sentence adds value, and the structure is front-loaded with the main 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?

The description covers the tool's purpose, all inputs, and the output (confirmation string). Given the existence of an output schema and the lack of additional complexity, it provides complete guidance for an AI agent to use this tool correctly.

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 coverage is 0%, but the description fully explains each parameter: user_google_email, file_id, permission_id, and dry_run. For dry_run, it provides the default value and behavior. This adds significant meaning beyond the raw schema.

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 verb 'removes' and the resource 'permission from a Google Drive file or folder'. It also explains the action as 'revoking access'. This distinguishes it from sibling tools like update_drive_permission or share_drive_file.

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 provides implicit guidance by noting that permission_id should come from get_drive_file_permissions, indicating a required preceding step. However, it does not explicitly state when to use this tool versus alternatives or mention any prerequisites beyond the parameters.

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