Manage Drive Access

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

Annotations already mark destructiveHint=true, which the description aligns with by mentioning revoke and transfer. However, the description adds no additional behavioral context beyond what annotations provide, such as side effects of ownership transfer or notification sending. The description is consistent but not additive.

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 two sentences, front-loading the core purpose ('Consolidated tool for managing...') and then listing actions succinctly. Every sentence contributes value without redundancy. Ideal length for a complex 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 high complexity (14 parameters, multiple actions) and the presence of an output schema, the description covers the tool's scope but lacks examples or guidance on action selection. It is minimally complete but could be more helpful with usage patterns.

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 input schema fully documents all 14 parameters. The tool description adds no extra parameter-level meaning or usage context beyond the schema, so it meets the baseline but does not elevate understanding.

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 it is a consolidated tool for managing Google Drive access permissions and explicitly lists all supported actions (grant, batch-grant, update, revoke, transfer ownership). This distinguishes it from sibling tools like set_drive_file_permissions and get_drive_file_permissions by positioning itself as a unified entry point.

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 does not explicitly guide when to use this tool versus its siblings. It implies it is for any permission management need but lacks concrete scenarios, alternatives, or exclusions. The guidance is implied but not actionable for an AI agent deciding between this and set_drive_file_permissions.

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