batch_share_drive_file

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

With no annotations, the description carries full behavioral disclosure. It reveals sequential processing, defaults for roles and notifications, and the return value with per-recipient success/failure. It does not mention auth requirements or potential partial-failure implications, but provides useful operational context.

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 long but appropriately structured with an overview, performance note, Args section, and Returns section. Every detail earns its place given the complex nested parameter and no schema descriptions. It is somewhat verbose but not wasteful.

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 completely covers purpose, behavioral nuances, all parameters, and return value. The output schema exists, but even without it, the description explains the string summary of created permissions. No critical gaps remain.

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?

The input schema has 0% description coverage, and the description compensates fully. It explains each parameter, the structure of recipient objects, required fields per share_type, defaults, and the domain alternative. This is as thorough as needed.

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 first sentence clearly states the tool shares a Google Drive file or folder with multiple users or groups in a single operation, using a specific verb and resource. This distinguishes it from the single-recipient share_drive_file sibling tool.

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 tool is for batch sharing with multiple recipients and adds a practical note about sequential processing and splitting large lists. It doesn't explicitly name the alternative for single-recipient sharing, but the batch semantics are clear.

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