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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains what the tool returns ('whether a sync is currently running, and the result of the last completed sync'), which is helpful. However, it doesn't cover other behavioral aspects such as error handling, rate limits, or authentication requirements, limiting its transparency.

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 and well-structured, consisting of two sentences that efficiently convey the tool's purpose and return value. Every sentence earns its place, with no wasted words, making it easy to understand quickly.

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 tool's low complexity (0 parameters, no annotations, but with an output schema), the description is reasonably complete. It explains what the tool does and what it returns, which is sufficient for a status-checking tool. However, it could benefit from more behavioral details, such as error cases or usage examples, to achieve full completeness.

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 parameters with 100% coverage, so no parameter documentation is needed. The description appropriately doesn't discuss parameters, focusing instead on the tool's functionality. A baseline of 4 is applied since the schema fully handles parameters, and the description adds value by explaining the tool's purpose without redundancy.

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's purpose: 'Check the status of the last or current GDrive sync.' It specifies the verb ('Check') and resource ('GDrive sync status'), making it easy to understand what the tool does. However, it doesn't explicitly differentiate from sibling tools like 'gdrive_sync' or 'sync_from_gdrive', which prevents a perfect score.

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 usage context by mentioning 'last or current GDrive sync,' suggesting it should be used to monitor sync operations. However, it lacks explicit guidance on when to use this tool versus alternatives like 'gdrive_sync' or 'sync_from_gdrive,' and doesn't specify prerequisites or exclusions, leaving some ambiguity.

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