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

With no annotations provided, the description carries full burden but only states the basic action without disclosing behavioral traits. It doesn't mention if this is a read-only operation, what permissions are required, potential errors, or the format of returned data, leaving significant gaps for an agent.

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, efficient sentence with no wasted words, making it easy to parse. It front-loads the key information appropriately, though it could benefit from more detail.

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 complexity implied by sibling tools (e.g., recovery operations), no annotations, no output schema, and low schema coverage, the description is inadequate. It doesn't cover behavioral aspects, return values, or usage context, leaving the agent with insufficient information for reliable invocation.

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 description mentions the 'id' parameter, but with 0% schema description coverage, it doesn't add meaningful semantics beyond the schema's type. It fails to explain what the ID represents, its format, or where to obtain it, so it only meets the baseline for minimal compensation.

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 action ('Get') and resource ('a specific unstructured data source by ID'), making the purpose understandable. However, it doesn't differentiate from sibling tools like 'GetAllUnstructuredDataServers' or 'GetUnstructuredDataShareIRSwitchoverSettings', which would require more specificity for 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 provides no guidance on when to use this tool versus alternatives like 'GetAllUnstructuredDataServers' for listing all sources or 'GetUnstructuredDataShareIRSwitchoverSettings' for related configurations. It lacks context about prerequisites or typical use cases.

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