drive_folder_info

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

With no annotations, the description carries the full burden. 'Verify' and 'service-account access' convey a read-only authentication check and identify the auth context. However, it does not disclose side effects, failure behavior, or operational details such as required environment setup.

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?

Single sentence with no wasted words; it front-loads the action and target. Appropriate length for such a simple, parameter-less 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 zero parameters and the presence of an output schema, the description is close to sufficient for selecting and invoking the tool. But with no annotations, it leaves unspecified prerequisites, side-effect expectations, and what a failed verification looks like.

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 tool has zero parameters, so schema coverage is trivially complete. The description adds useful context by indicating that the target folder is identified externally via GOOGLE_DRIVE_FOLDER_ID rather than through a tool parameter.

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 identifies the action ('Verify') and the target ('Google Drive service-account access to GOOGLE_DRIVE_FOLDER_ID'). This distinguishes it from sibling upload tools, though it does not explicitly describe what folder information will be returned.

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 gives no explicit guidance on when to use this tool versus alternatives, and it names no sibling tools. It implies a preflight/setup access-check use case, but the agent must infer this context.

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