Get Drive File Permissions

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

Annotations already declare it as read-only, idempotent, non-destructive. The description adds detail beyond annotations by specifying the exact metadata returned (permissions, parent folders, ownership, timestamps). This additional context helps the agent understand the scope of data retrieved, complementing the safety profile from annotations.

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 sentence that front-loads the verb and resource, concisely listing the key data points without extraneous detail. Every word is necessary and adds value.

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 (2 simple parameters, no nested objects, output schema exists), the description covers the essential metadata returned. It lacks mention of pagination or error conditions, but these are less critical for a straightforward read operation. An output schema is present, so return values need not be detailed.

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 100% and both parameters are clearly described in the schema. The description does not add extra meaning beyond what the schema provides. With full schema coverage, baseline 3 is appropriate.

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 tool 'gets detailed metadata about a Google Drive file' and enumerates specific items like permissions, parent folder IDs, ownership, and timestamps. It uses a specific verb and resource, distinguishing it from the sibling 'check_drive_file_public_access' which is more narrow.

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 explicit guidance on when to use this tool versus alternatives. The description is straightforward but lacks context about when it is appropriate or when to prefer other tools like 'check_drive_file_public_access' or 'get_drive_file_content'. However, the simplicity of the tool makes usage somewhat implicit.

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