ShowAPI Creative Design Image Generation

Problem It Solves

This skill targets creative design image generation as a controlled pipeline rather than free-form prompt expansion. It turns a request into a checkable workflow: the user supplies a theme, optional reference image, grid count, and aspect ratio; the skill submits a generation task and tracks the async result until the image URL is returned. It is useful when engineers or product workflows need to turn “4-grid poster”, “reference-image style extension”, or “single-image theme art” into concrete deliverables.

Workflow and Key Capabilities

• Parameter fallback: grid_num supports only 1, 2, 3, and 4; invalid values fall back to 4. Aspect ratios such as 1:1, 3:4, and 16:9 affect the final canvas.
• Mechanical prompt construction: prompts are assembled from validated parameters without semantic rewriting, making the generation process more predictable.
• Async execution: real calls first submit a task and return a task_id, then poll the query endpoint; each poll should surface current status to the user.
• Result handling: the final output includes the image URL, the effective grid count and aspect ratio, and the constructed prompt; results are usually rendered in an HTML page with the image first.

Boundaries

Without showapi_appkey, the skill uses a mock call that returns a one-shot preview result and does not run execute_task.py or query_task.py. Mock output is only for previewing effects and should not be treated as real production output. Real calls require a ShowAPI AppKey, and all tasks are forced to run asynchronously rather than synchronously.
