remix_image

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

The description discloses that the tool returns a task id, status, and output URLs, giving some insight into expected outputs. However, it does not explain the synchronous/asynchronous behavior, the effect of the wait parameter (default true), or any side effects such as image modification. With no annotations provided, the description should cover more behavioral traits.

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, efficiently stating the main purpose and return values. It is front-loaded with the action. However, some brevity is sacrificed at the expense of completeness, as key details are omitted.

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 tool has 9 parameters, no output schema, and no annotations, the description is insufficiently complete. It lacks workflow context (e.g., pairing with get_task for async polling) and does not explain the purpose of most parameters. An agent would struggle to use this tool correctly.

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?

The input schema has 9 parameters with only 22% description coverage. The tool description adds no parameter-level information beyond the high-level action. An agent cannot understand the meaning of parameters like prompt, source_image_url, or aspect_ratio from the description alone.

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 'Create a Flux task on RunAPI (remix image)', which clearly indicates the action and resource. However, it does not distinguish from the sibling 'text_to_image', which likely creates from text rather than remixing an existing image. The parenthetical 'remix image' helps but lacks explicit differentiation.

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 like text_to_image or get_task. There is no mention of prerequisites, when not to use, or recommended context, leaving the agent to infer from the tool name alone.

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