Create Users By Id Image

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

No annotations are present, so the description carries the full burden of behavioral disclosure, but it only states that the tool updates a user image. It does not indicate whether an existing image is overwritten, what permissions are required, how binary data is handled, or what the response looks like.

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 short and front-loaded, but it is under-specified rather than appropriately concise. A single vague sentence omits nearly all information needed to invoke the tool correctly.

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?

With no annotations, no output schema, and zero parameter documentation in the description, this tool definition is far too incomplete for a binary image mutation operation. It leaves request format, target semantics, and response behavior entirely unaddressed.

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 0%, and the description does not mention id, profile, or accept-language at all. The agent cannot learn that id targets a specific user, that profile contains the image binary content, or how accept-language affects the request.

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 a clear verb and resource ('Updates a User Image'), but this directly conflicts with the tool name 'create_users_by_id_image', creating ambiguity about whether the operation creates or updates. It also does not distinguish itself from sibling image tools such as update_recipes_by_slug_image or get_media_users_by_user_by_file_name.

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 no guidance on when to use this tool versus alternatives, and no exclusions or context are given. An agent cannot determine the correct situations for this tool based on the provided text.

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