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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions starting a session but doesn't clarify if this is a read-only or destructive operation, what permissions are required, whether it's asynchronous, or what the expected outcomes are. For a tool that likely initiates a restore process, this is a significant gap in 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 a single, efficient sentence that directly states the tool's purpose without unnecessary words. It is appropriately sized and front-loaded, making it easy to parse 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 complexity of initiating a restore session, no annotations, no output schema, and undocumented parameters, the description is incomplete. It doesn't explain what the tool returns, how to manage the session, or any behavioral nuances, making it inadequate for effective use by an AI agent.

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 1 parameter ('body') with 0% description coverage and no details in the schema. The description adds no information about what 'body' should contain, such as backup identifiers, restore options, or session settings. With low schema coverage, the description fails to compensate, leaving parameters undocumented.

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 ('Start a file-level restore session') and the resource ('from an unstructured data backup'), which provides a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'StartFlrMount' or 'StopUnstructuredDataFLRMount', which appear to be related operations.

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, prerequisites, or exclusions. It lacks context about when this operation is appropriate compared to other restore or mount tools in the sibling list, such as 'InstantUnstructuredDataRecoveryMount' or 'EntireUnstructuredDataShareRestore'.

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