creatok-generate-image（创建图像）

generate-image

Constraints

• The model's final user-facing response should match the user's input language, default English.
• Must request user confirmation before triggering any paid/high-cost image generation call.
• After confirmed, must call CreatOK Open Skills proxy and wait until completion.
• Avoid technical wording in the user-facing reply unless the user explicitly needs details for debugging.

Model Selection Rules

The skill must read model list, defaults, and hard limits from the CreatOK capabilities endpoint at runtime instead of hardcoding them locally.

Keep the local client thin:

• use the returned default model unless the user explicitly chooses another supported model
• validate only hard execution constraints such as resolution, aspect ratio, count, and reference-image cap
• keep user-facing model explanation minimal and avoid depending on provider, family, or hint-style metadata

Inputs to clarify (ask if missing)

• ask only for what is necessary to generate a good image
• if resolution or aspect ratio is not specified, use the model defaults returned by the capabilities endpoint
• if the prompt is vague, offer to refine it before confirming generation
• reference images are optional — ask only if the user implies style transfer or subject reference
• when reference images are used, upload the local image file first and submit the returned uploaded reference with the generation task

Workflow

1. Confirmation gate (mandatory)

• Summarize:

- model - resolution - number of images (n) - aspect ratio if specified - estimated cost/credits if available

• Ask for a simple confirmation before submitting.
• Do not submit the generation task until user says yes.

1. Submit image generation

• Call CreatOK: POST /api/open/skills/image-generation

1. Poll status until completion

• Call CreatOK: GET /api/open/skills/tasks/status?task_id=...&task_type=image_generation

1. Persist artifacts + respond

• Write:

- outputs/result.json with task_id/status/images/raw - outputs/result.md

• Persist the task_id immediately after submission so the user can recover later.
• Return the final image URLs verbatim.

Existing Task Recovery

• If the user already has a task_id, continue from that task instead of starting a new one.
• In recovery mode, do not ask the user to restate the prompt if the task id is already available.
• The model can either check status once or keep polling if the user wants to wait.
• If the task succeeded, return the final image URLs verbatim.
• If the task is still queued or running, explain clearly and offer to keep checking.
• If the task failed, explain the failure and suggest next steps.

Artifacts

Thin Client Boundary

• This skill submits generation jobs, polls status, and persists fixed-format outputs.
• The model should not make the user restate their idea if the direction is already clear from the conversation.
