create_users_by_id_image

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

With no annotations and a minimal description, the tool's behavioral traits are not disclosed. It does not mention if the update replaces the image, requires authentication, or has side effects. The name-description inconsistency also raises questions about the actual operation.

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 sentence with no wasted words, but it is under-specified. For a mutation tool with three parameters and no annotations, more information is needed, so conciseness here sacrifices completeness.

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 complexity of user image management (authentication, file handling, overwrite behavior), the description is insufficient. No output schema or annotations exist to compensate. The sibling tools list includes relevant alternatives, but no context is provided to choose appropriately.

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 provides no additional meaning for the three parameters (id, profile, accept-language). The profile parameter's content type suggests binary upload, but this is not explained.

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 'Updates a User Image' is clear about the action and resource, but the tool name starts with 'create' which contradicts the description. This mismatch confuses the purpose. Additionally, sibling tools like update_users_by_item and create_recipes_by_slug_image exist, but no differentiation is provided.

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 is given on when to use this tool versus alternatives (e.g., update_users_by_item, get_media_users_by_user_by_file_name). The description lacks any context about prerequisites or exclusions.

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