Upload_Document

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

No annotations are provided, so the description must fully disclose behavioral traits. It covers content encoding (UTF-8 or Base64) and folder_name defaulting, but does not describe error conditions, authentication needs, rate limits, or the return value (though an output schema exists). This is adequate but not fully comprehensive.

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 extremely concise with two sentences. The first sentence front-loads the action and resource, and the second adds key usage detail. Every word earns its place with no redundancy.

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 has 4 parameters, an output schema, and many sibling tools, the description is fairly complete. It covers content encoding and folder root behavior. It could mention return value or error scenarios, but the output schema likely fills that gap. Overall sufficient for a simple upload tool.

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% description coverage, so the description must add meaning. It clarifies the 'content' parameter format and the 'folder_name' default behavior, but does not explain 'file_name' or 'is_base64' beyond their schema titles. This adds partial value but leaves gaps.

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 'Upload a new document' to a 'SharePoint folder', using specific verbs and resource. It distinguishes from sibling tools like 'Upload_Document_From_Path', which uploads from a file path. The description also specifies the content format and a notable parameter behavior (folder_name default).

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 implicit usage guidance (e.g., using empty string for folder_name to upload to root) but lacks explicit when-to-use or when-not-to-use context. It does not differentiate from alternatives such as 'Upload_Document_From_Path' or explain when to prefer this tool over similar ones.

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