microsoft_upload_file

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

No annotations are provided, and the description does not disclose behavioral traits such as overwrite behavior, file size limits, required permissions, or success/failure outcomes. For a mutation operation like upload, this is a significant gap.

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 with three sentences, but the content does not earn its place due to lack of actionable details. The routing information is useful but the overall contribution is limited.

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 a file upload operation and the presence of an output schema, the description should explain at least what the arguments JSON should contain and any constraints. It is incomplete and leaves the agent with insufficient information.

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 only parameter 'arguments' is described as a JSON string for the connector operation, which adds minimal meaning beyond the schema. With 0% schema description coverage, the description fails to detail expected keys, mandatory fields, or examples, providing little help for correct invocation.

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 states it is a Microsoft connector operation for upload_file, which implies file upload, but does not specify the target location (e.g., OneDrive, SharePoint) or differentiate from siblings like microsoft_update_file. The purpose is clear at a high level but lacks specificity.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, use cases, or contexts where this tool is appropriate or preferred over other file-related tools.

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