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 but offers minimal information. It does not address overwrite behavior, file size limits, authentication requirements, error handling scenarios, or whether the operation is atomic—critical details for a file mutation tool.

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 immediately states the tool's function without redundancy. However, given the complexity of file write operations and the complete lack of schema documentation, the extreme brevity leaves significant gaps rather than being appropriately informative.

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?

For a destructive file operation with no annotations, no output schema, and an empty input schema, the description is inadequate. It fails to compensate for the missing structured metadata by explaining required inputs, return values, or side effects necessary for an agent to invoke the tool successfully.

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 contains zero parameters, which establishes a baseline score of 4 per evaluation rules. The description does not mention parameters, which is consistent with the empty schema, though this raises questions about how the tool receives file content and destination paths.

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 core action ('Write or upload') and target resource ('file to OneDrive'). However, it does not clarify the distinction between 'write' and 'upload' operations or explicitly differentiate from sibling tools like onedrive_read_file or onedrive_delete_file, though this is somewhat implied by the tool name.

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 for use (e.g., file path formatting), or exclusion criteria. Given the empty input schema, the description fails to indicate what inputs are expected to perform the write operation.

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