upload_image

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

No annotations are provided, so the description carries the full burden. It says this uploads into ComfyUI but does not disclose mutation behavior, overwrite/name-collision handling, authentication requirements, size limits, or what the tool returns. For a write-side upload operation, these omissions are significant.

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 definition is a single front-loaded sentence with no wasted words. It states the action, target system, and intended workflow use immediately.

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?

The tool is simple and all parameters are fully documented in the schema. Still, with no annotations and no output schema, the description should ideally explain the upload result or key behavioral constraints. It is adequate but has clear gaps for an agent invoking an 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?

Schema description coverage is 100%, so both parameters are already documented in the schema. The description does not add meaning beyond the schema for image_path or subfolder, so the 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 gives a clear verb+resource: upload an image to ComfyUI. It also states intended use in image-to-image or controlnet workflows. It does not explicitly differentiate from sibling tools, but no sibling appears to be an uploader, so the purpose is still clear.

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?

It implies when to use the tool by naming image-to-image and controlnet workflows. However, it does not say when not to use it, nor does it name alternatives or prerequisites. Usage context is present but not fully actionable.

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