Official
by runapi-ai

remix_image

Create a Qwen Image remix task from a prompt and source image URL. Returns task ID, status, and output URLs for polling.

Instructions

TDQS

B3.3/5.0
Behavior3/5

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

With no annotations, the description carries the full behavioral burden, and it does disclose the async task-creation model and the return shape (task id, status, output URLs), which is genuinely useful. It omits any mention of authentication, cost/pricing implications (a sibling check_pricing hints these matter), or how the wait/polling behavior affects the call, leaving meaningful gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, zero waste, with the core action front-loaded and the return contract appended. Nothing is padded or redundant.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a 10-parameter creation tool with no annotations and no output schema, the description partially compensates by naming the return fields (task id, status, output URLs). However, it says nothing about the async/polling workflow, cost, or when to prefer this over sibling image tools, so an agent still lacks key context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 80%, so the schema already documents most parameters (seed, strength, source image constraints, output format, callback URL). The description adds no parameter-level meaning beyond what the schema provides, which matches the baseline of 3 when schema coverage is high.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Create a Qwen Image task on RunAPI') with the remix intent parenthetically clarified, so the agent knows this generates an image from a source image. It does not, however, contrast itself with siblings like edit_image or text_to_image, so the agent must infer which image tool applies.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no statement of when to use this tool versus edit_image or text_to_image, and no prerequisites or exclusions are given. The agent is left to infer usage purely from the name and the required source_image_url parameter.

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