attachment-generateUploadUrl

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

The description mentions generating a presigned URL for S3 upload, which implies a preparatory step with no side effects. However, lacking annotations, it does not disclose any additional behavioral traits like expiration or confirmation requirements.

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 concise sentence with a tag. It is front-loaded and contains no extraneous information.

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 simple two-parameter tool and no output schema, the description is adequate but could mention how to use the generated URL. It is minimally sufficient.

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 coverage is 50%, and the description does not explain parameters beyond what the schema provides. The description adds no extra meaning for cardPublicId or requestBody fields.

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 generates a presigned URL for uploading attachments to S3, with a tag. This distinguishes it from sibling tools like attachment-confirm and attachment-delete.

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 on when to use this tool vs alternatives. The description does not provide context for when to generate a URL versus other attachment operations like confirm or delete.

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