API Key	https://kpainter.ai/api-key

Setup

If KPainter is not connected:

1. Ask the user to sign up or sign in at https://kpainter.ai/.
2. Send the user to https://kpainter.ai/api-key.
3. Ask the user to activate, copy, and connect their API key to the current agent.
4. Confirm setup only after the user says the key is connected.

Keep the key inside the current agent connection flow. Never ask the user to send it to unrelated services.

Products And Public API Types

Explainer Video and Read Aloud Video are independent products. Never present them as Standard and Lite modes.

Product	Public API type	Best for
Explainer Video	explainer_video	continuous animated scenes and narration for explainers, brand communication, and stories
Read Aloud Video	read_aloud_video	narrated visuals and page-by-page structure for courses, training, SOPs, science, and longer topics
Vector Animation	vector_animation	precise vector explanations when the user explicitly requests Vector Animation
AI Image	image	covers, posters, illustrations, and visual summaries
AI Video	ai_video	storyboard videos, cinematic shots, and short videos
AI PPT	slides	editable PPT/PDF presentations
AI App	interactive_lesson	clickable apps, lessons, demos, exercises, and learning experiences

Use the public types in this table. Do not describe Read Aloud Video as “Lite” or a mode under Explainer Video.

Choose The Product

Route by the result the user wants.

1. Map an explicit “Explainer Video,” “解说视频,” or “讲解视频” request to explainer_video.
2. Map an explicit “Read Aloud Video” or “绘本视频” request to read_aloud_video.
3. Use vector_animation only when the user explicitly says “Vector Animation” or “矢量动画.” Algorithms, formulas, structures, workflows, diagrams, or generic animation requests alone are not enough.
4. Map AI Image, poster, cover, illustration, or single-visual requests to image.
5. Map storyboard-video, cinematic-shot, or short-video requests to ai_video.
6. Map AI PPT, presentation, and slide-deck requests to slides.
7. Map AI App, clickable lesson, app, interactive page, quiz, or simulation requests to interactive_lesson.
8. Treat PDFs, PPTs, URLs, images, and documents as source formats, not output-type signals.
9. If the user only says “video,” ask whether they want an Explainer Video, Read Aloud Video, or AI Video. Do not offer or select Vector Animation unless the user explicitly requests it.
10. Never switch products silently because of credits or unsupported parameters.

Do not expose API type names unless the user asks for technical details.

Explainer Video

Choose Explainer Video when the user wants:

• continuous animated scenes and narration
• clear explanation with visual pacing
• science communication or brand storytelling
• a short piece designed to be watched and shared
• children’s stories or other story-led knowledge

Examples:

• Make a 30-second Explainer Video about MCP with continuous animated scenes and narration.
• Turn this topic into an Explainer Video with continuous visual storytelling.
• 做一个 30 秒左右的解说视频，用连续动态画面和旁白讲清楚 MCP。
• 做一个适合传播的解说视频成片。

When the user gives no duration, suggest about 30 seconds first. Read current duration limits from the catalog.

Read Aloud Video

Choose Read Aloud Video when the user wants:

• clear, page-by-page explanation
• narrated visuals
• course or classroom content
• training, SOP, or product walkthroughs
• longer topics with stable information density
• a lower-cost alternative to Explainer Video

Examples:

• Make a Read Aloud Video that teaches MCP in 6 pages.
• Turn this training manual into a narrated Read Aloud Video.
• 做一个绘本视频，用 6 页分步骤讲清楚 MCP。
• 把这份培训手册做成绘本视频。

Load valid page counts, voices, styles, ratios, and qualities from the catalog.

Vector Animation

Choose Vector Animation only when the user explicitly requests that product.

Examples:

• Use Vector Animation to show how binary search removes half of the range in each round.
• Use Vector Animation to animate this system architecture and data flow.
• 用矢量动画讲清楚二分查找。
• 请用矢量动画展示这个机制和状态变化。

AI Image Models

Read image.generation_models from /catalog and use a model-specific request.

• Nano Banana 2: provider=gemini, model=nano-banana-2; use only its listed ratios.
• GPT Image 2: provider=azure_openai, model=gpt-image-2; quality=low|medium|high is separate from top-level output_quality.

Never send the internal extra_config.output shape. Use top-level aspect_ratio and output_quality.

AI Video Models

Use one public type, ai_video, with model selection inside video_generation.

Model	Public behavior
gemini-omni-flash	720p text-to-video with native audio; supports iterate follow-up edits
veo-3.1-fast	fast text-to-video; model catalog controls resolution and duration; no conversational edit
veo-3.1-standard	quality-first text-to-video; model catalog controls resolution and duration; no conversational edit

Example:

json

{
  "type": "ai_video",
  "prompt": "Move slowly through a futuristic city on a rainy night with natural ambient audio",
  "aspect_ratio": "16:9",
  "video_generation": {
    "model": "gemini-omni-flash",
    "task": "text_to_video",
    "resolution": "720p",
    "duration_seconds": 8,
    "native_audio": true
  }
}

For an Omni follow-up, read editable_actions, then send:

json

{
  "action": "iterate",
  "prompt": "Keep the camera motion and make the lighting warmer"
}

Never expose or ask the user for previous_interaction_id; KPainter manages it server-side. Do not attempt iterate with Veo.

The current Public OpenAPI supports text-to-video only. Do not send first frames, last frames, attachments, or image/video tasks until /catalog reports those public capabilities.

Credit Fallback

If the user wants Explainer Video but does not have enough credits:

1. Explain that the current Explainer Video may exceed the available credits.
2. Offer Read Aloud Video as the lower-cost alternative.
3. Keep the topic, audience, and language unchanged.
4. Ask before switching.

Recommended wording:

• Your current credits may not cover a full Explainer Video. I can keep the same topic and language and switch to a clear, lower-cost Read Aloud Video. Would you like me to switch?
• 当前积分可能不够生成完整解说视频。我可以保留主题和语言，改成结构清晰、成本更低的绘本视频，要切换吗？

Collect Only Missing Information

Ask one short question at a time and only for missing details:

• topic
• audience
• output language
• duration or scene/page count
• tone or visual direction
• aspect ratio
• source files or URLs

If the user already gave enough information, create first and refine after.

Use Source Material

Treat attachments and URLs supplied by the user as source or reference material.

Direct public API upload is not currently available. If the active host does not expose an attachment bridge, summarize the supplied material into the request or ask the user to continue through the main-site creator instead of inventing an upload result.

• Preserve the user’s requested facts and terminology.
• Do not invent claims that are not supported by the source.
• Ask which source takes priority if references conflict.
• Keep the requested output language unless the user asks to switch.

API Workflow

For OpenAPI or MCP integrations:

1. Validate the user API key.
2. Read /catalog before choosing type-specific parameters.
3. Create the result.
4. Poll the job until it succeeds or fails.
5. Read the final creation detail for URLs, artifacts, and scenes.
6. Before scene editing, inspect editable_actions and existing scenes.

Use catalog values as the source of truth for:

• public content types
• languages and voices
• styles
• aspect ratios and qualities
• generation models, tasks, resolutions, and durations
• duration limits
• scene/page limits

Parameter rules:

• explainer_video uses duration_seconds.
• read_aloud_video uses scene_count.
• slides uses scene_count.
• ai_video uses video_generation; its duration is nested under video_generation.duration_seconds.
• Never send duration_seconds to read_aloud_video or vector_animation.
• Never send scene_count to explainer_video.
• Never send raw extra_config, internal source records, or provider interaction IDs.

Refinement

After the first result, help the user:

• shorten or expand it
• revise narration
• change voice or visual direction
• regenerate a selected scene
• switch products

Confirm before switching products. Never silently change type, audience, language, or format.

Multilingual Support

KPainter supports creation and refinement in the user’s preferred language.

Examples:

• Make an Explainer Video about AI agents with continuous animated scenes and narration.
• Make a Read Aloud Video that explains MCP page by page.
• 帮我做一个解说视频，用连续动态画面讲清楚 MCP。
• 做一个绘本视频，逐页讲解 MCP。
• MCP を段階的に説明する解説動画を作ってください。
• أنشئ فيديو معرفيًا مصقولًا يشرح MCP.
• Crea un video explicativo paso a paso sobre MCP.
• MCP를 단계별로 설명하는 해설 영상을 만들어 주세요.
• Crée une vidéo de connaissance soignée sur MCP.

These are examples, not a language allowlist.

Install

OpenClaw / ClawHub

bash

openclaw skills install kpainter

Skills CLI

bash

npx skills add OriginwiseAI/skills --skill kpainter

While this repository contains one public skill, this also works:

npx skills add OriginwiseAI/skills

Direct URL

Give the agent:

https://kpainter.ai/skill.md

Local Folder

bash

mkdir -p ~/.codex/skills/kpainter
curl -s https://kpainter.ai/skill.md > ~/.codex/skills/kpainter/SKILL.md

Security

• The API key belongs to the user.
• Do not send it to unrelated services.
• Do not present the agent as the account owner.
• If the key is reset, ask the user to reconnect it.

Success Criteria

The skill succeeds when the agent can:

• explain Explainer Video and Read Aloud Video as independent products
• use the current public API type names
• choose the appropriate product from user intent
• choose Vector Animation only after an explicit Vector Animation or 矢量动画 request
• ask only for missing information
• create, poll, read, and refine results
• choose AI Image and AI Video models from the catalog and use model-specific parameters
• use Omni iterate only when the selected model exposes conversational editing
• offer Read Aloud Video as a confirmed lower-cost fallback when appropriate
