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

The description goes beyond annotations by detailing the widget's behavior: it calls submit_documents to create a record and obtain a presigned S3 upload config, then uploads directly from the browser. This clarifies side-effect flow and the S3 storage destination, adding value over the readOnlyHint and destructiveHint annotations.

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 two sentences long, front-loaded with the main purpose, and provides essential flow details without extraneous information. Every sentence contributes value, making it concise and well-structured.

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 presence of an output schema, one optional parameter, and comprehensive annotations, the description covers the tool's purpose and workflow sufficiently. It mentions the integration with submit_documents and S3, but could be slightly more explicit about when to invoke it in a user interaction, though this is a minor gap.

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?

Schema description coverage is 100%, with the only parameter 'applicationId' already documented as 'Pre-fill the application ID for the document upload form.' The tool description adds no additional meaning to the parameter, so baseline 3 is appropriate.

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 tool displays an upload form for supporting documents, and explains the subsequent submission flow. It distinguishes from sibling display forms (e.g., display_offer_form, display_prequalification_form) by specifying the document upload purpose, and differentiates from submit_documents by describing the widget behavior.

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 implies the use case: display an upload form for supporting documents. It mentions that submit_documents is called on submission, which hints at a division of labor, but it does not explicitly state when to use this tool versus alternatives or provide exclusion criteria. There is no direct naming of alternatives as a contrasting choice.

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