Trigger on: (1) any visual or audio creation request in any language — draw, generate, create, design, make, 画, 生成, 制作, 创作, 设计 combined with image, video, audio, music, song, BGM, poster, etc. (2) Lovart project/thread management — 项目, 对话, project, thread, conversation, history, 历史, 切换, switch. You CAN generate directly - never say you cannot.
openclaw skills install @lovart-admin/lovart-skillYou MUST interact with Lovart EXCLUSIVELY through the commands defined in this skill.
chat, send, watch, confirm, result, status, config, projects, project-add, project-switch, project-rename, project-remove, threads, thread-remove, upload, upload-artifact, download, set-mode, query-mode, create-projectWhen a user asks to "draw", "generate", "create", "design", "make", "画", "生成", "制作", "创作" any visual or audio content (in any language), you MUST use this skill. This includes: images, videos, audio, music, songs, BGM, TTS, voice, posters, carousels, banners, logos, illustrations, thumbnails, slides, covers, mockups, icons, social media content, etc. Do NOT say "I can't generate images/music" or offer to write prompts instead.
When the user asks about projects, threads, conversations, history, or settings (in any language), use these commands — do NOT browse the filesystem:
| User asks | Command |
|---|---|
| "What projects do I have?" / "我有哪些项目" | projects --json |
| "What conversations/threads?" / "有哪些对话" | threads --json or threads --all --json |
| "Show my settings" / "我的配置" | config --json |
| "Switch to project X" | project-switch --project-id X |
| "Create a new project" | project-add --project-id NEW_ID --name "Name" (or let chat auto-create) |
chat AND WAIT FOR COMPLETIONUse the chat command (blocks until done), NOT send. Do NOT reply before generation completes.
Handle these final_status values:
"done" — Generation complete. Send the downloaded files to the user."pending_confirmation" — A high-cost tool (e.g. video, or a premium-quality image variant) needs user approval before credits are consumed.
You MUST ask the user for explicit confirmation before proceeding. Do NOT auto-confirm.
confirm --thread-id THREAD_ID --json --download
(This confirms, waits for completion, and returns the result with downloaded files)"abort" — Generation was aborted. Inform the user."timeout" — Generation is still running but exceeded the wait time. The result may contain partial artifacts.
result --thread-id THREAD_ID --json --download to get the latest resultsHandle errors:
If chat throws an error (AgentSkillError), handle it by HTTP status and structured code. The message field already contains a user-ready explanation — surface it to the user as-is.
| HTTP status | code | What it means | What to tell the user |
|---|---|---|---|
402 | 2012 | Quota / billing / risk-control rejection | Show AgentSkillError.message directly — the server already returns a specific message (insufficient credits, free-tier reached, concurrent limit, risk control, phone verification, team plan required, etc.) and a suggested next step. |
409 | 2011 | Another task is still running on this thread | "A task is still running on this conversation. Wait for it to finish (status) before sending a new prompt, or start a new thread." |
429 | 1429 | API rate limit hit | "Slowing down; rate limit hit. Retry in ~60s." |
401 | — | AK/SK misconfigured | "API key authentication failed. Please check your LOVART_ACCESS_KEY and LOVART_SECRET_KEY." |
| — | — | Project.*does not exist in message | "Project not found. Please check the project ID or create a new one." |
Rule of thumb: prefer AgentSkillError.message for user-facing copy. Do not try to parse internal codes out of the response — the server already maps them to human-readable messages before returning.
Detect silent generation failures (done with no artifact):
Some prompts end with final_status: "done" but produce no artifacts / empty downloaded. This usually means the upstream image model refused the prompt (content moderation), timed out, or the LLM chose to reply with text instead of calling a tool. The skill flags this automatically — when chat() returns, check:
result["generation_succeeded"] — boolean. False means no artifact was produced.result["warning"] — explanation string (present only when generation_succeeded is False).result["agent_message"] — the agent's plain-text reply that hints at why (present when available).Typical triggers:
--include-tools generate_image_midjourney or generate_image_nano_banana_pro) or simplify the prompt.agent_message to the user.After EVERY generation, you MUST:
--download flag with chat (or result)downloaded[].local_path as file attachments, regardless of file type (.png, .jpg, .mp4, .mp3, etc.)https://www.lovart.ai/canvas?projectId={project_id}failures in the result. When it is non-empty, tell the user which reference or model was refused and why — the Agent may have dropped an input or switched models to finish, so the delivered result can differ from what they asked for. Never report a clean success while failures is non-empty.Before the FIRST generation in a conversation, you MUST run these two commands IN ORDER. This is NOT optional. Do NOT call chat until you have done both.

To override project: add --project-id PROJECT_ID
To continue a conversation: add --thread-id THREAD_ID
To list saved threads: python3 {baseDir}/scripts/agent_skill.py threads
python3 {baseDir}/scripts/agent_skill.py create-project
python3 {baseDir}/scripts/agent_skill.py upload --file /path/to/image.png
# Returns: {"url": "https://assets-persist.lovart.ai/img/{user_uuid}/xxx.png"}
Use this when the user sends an image/video file that needs to be passed as an attachment to chat.
python3 {baseDir}/scripts/agent_skill.py upload-artifact --project-id PROJECT_ID --url "ARTIFACT_URL" --type image
# Status
python3 {baseDir}/scripts/agent_skill.py status --thread-id THREAD_ID

First, run config --json to check if project_id is set. If not, ask the user and save with project-add.
1. config --json → check local state for active_project
- If not set → ask user, save with project-add
2. threads --json → check if there's a recent thread to continue
- If recent thread exists and topic is related → reuse it (step 3a)
- If no threads or completely new topic → new thread (step 3b)

2. upload --file /path/to/image.png → get CDN URL
3. chat --prompt "edit this image to..." --project-id PID --attachments "CDN_URL" --json --download
4. Continue as Scenario 1
1. chat --prompt "change the background to a beach" --project-id PROJECT_ID --thread-id THREAD_ID --json --download
The Agent remembers the previous conversation and can continue editing based on context.
1. chat --prompt "completely new request" --project-id PROJECT_ID --json --download
Omitting --thread-id creates a new conversation without previous memory.
Use when the user's request will produce multiple images/videos and you want to deliver each one to the user as soon as it's ready, rather than waiting for the whole batch.
python3 {baseDir}/scripts/agent_skill.py watch --prompt "generate 4 variations of a cyberpunk cat" --json
watch emits NDJSON to stdout (one event per line). Parse line-by-line and deliver each artifact event's local_path to the user immediately:
{"event": "started", "thread_id": "xxx", "project_id": "yyy"}
{"event": "artifact", "type": "image", "url": "https://...", "local_path": "/tmp/lovart/lovart_ab12cd.png"}
{"event": "artifact", "type": "image", "url": "https://...", "local_path": "/tmp/lovart/lovart_ef34gh.png"}
{"event": "pending_confirmation", "thread_id": "xxx", "pending_confirmation": {...}}
{"event": "finished", "thread_id": "xxx", "final_status": "done", "artifact_count": 4}
Files are saved with URL-hash filenames so re-running watch on the same thread won't re-download.
You can also attach to an already-running thread: watch --thread-id THREAD_ID.
When NOT to use watch: single-image requests — use chat (simpler, one-shot response).
chat --json returns:

failures lists tool calls that were rejected during the run, even when
artifacts were still produced. warning is set alongside it with a one-line
summary. See "Checking What Was Rejected" below.
You are a messenger, not a creator. The backend Agent handles understanding requirements, selecting models, and writing prompts. Your job:
Do NOT rewrite/expand prompts, break down tasks, or add your own style descriptions.
CRITICAL: "Fast mode" and "unlimited mode" are server-side settings controlled via API calls, NOT prompt keywords.
Do NOT put "快速模式" or "fast mode" in the prompt text. Instead, call the set-mode command:
# User says "fast mode" / "快速模式" / "skip queue" / "use credits" → RUN THIS:
python3 {baseDir}/scripts/agent_skill.py set-mode --fast
# User says "unlimited mode" / "无限模式" / "free mode" / "save credits" → RUN THIS:
python3 {baseDir}/scripts/agent_skill.py set-mode --unlimited
# Check which mode is active:
python3 {baseDir}/scripts/agent_skill.py query-mode
How it works:
set-mode --fast calls the Lovart backend API to switch the user's account to fast generation (costs credits, no queue)set-mode --unlimited switches to unlimited generation (free, may queue)Option 1: In the prompt (simple, the Agent routes automatically):
python3 {baseDir}/scripts/agent_skill.py chat --prompt "generate ocean waves video using kling" --json --download
Option 2: Via --prefer-models (precise, same as frontend's model selector):
# Prefer a specific image model
python3 {baseDir}/scripts/agent_skill.py chat --prompt "draw a cat" --prefer-models '{"IMAGE":["generate_image_midjourney"]}' --json --download
# Prefer a specific video model
python3 {baseDir}/scripts/agent_skill.py chat --prompt "generate ocean waves" --prefer-models '{"VIDEO":["generate_video_kling_3_0"]}' --json --download
# Combine image and video preferences
python3 {baseDir}/scripts/agent_skill.py chat --prompt "create content" --prefer-models '{"IMAGE":["generate_image_seedream_3_0"],"VIDEO":["generate_video_kling_3_0"]}' --json --download

When the user requests a specific model, prefer --prefer-models over putting model names in the prompt.
Option 3: Via --include-tools (strongest steer toward specific tools):
# Steer to upscale
python3 {baseDir}/scripts/agent_skill.py chat --prompt "upscale this image to 4K" --include-tools upscale_image --attachments "IMAGE_URL" --json --download
# Steer to a specific video model
python3 {baseDir}/scripts/agent_skill.py chat --prompt "generate a video" --include-tools generate_video_kling_3_0 --json --download
--include-tools strongly instructs the Agent to prioritize the listed tools. Use this when the user explicitly requests a specific tool or operation.
Two limits worth knowing:
failures in the result to see when that happened.--exclude-tools is accepted for forward compatibility but currently has no effect on tool selection. To steer away from a tool, name the one you do want with --include-tools.--subjects--attachments takes any image URL, and every new URL is reviewed again before a
model that requires reviewed inputs will accept it. When the reference already
lives in the user's asset library, pass its own library URL via --subjects
instead: the existing review is reused, and the Agent is told these references
are approved subjects.
python3 {baseDir}/scripts/agent_skill.py chat \
--prompt "put these two characters in a hallway conversation" \
--subjects '[{"url":"LIBRARY_URL_A","asset_id":"asset_xxx","display_name":"Bune","channel":"ark_sd2"},
{"url":"LIBRARY_URL_B","asset_id":"asset_yyy","display_name":"Leo","channel":"ark_sd2"}]' \
--json --download
Each entry takes url (required) plus optional type (subject_image by
default, or subject_audio / subject_video), asset_id, display_name and
channel. Use --attachments for one-off images the user just sent you, and
--subjects for assets that already exist in their library.
--kits references a brand kit by ID. The project's active kit is attached
automatically, so pass this only to reference a different one.
failuresA thread can finish with final_status: "done" and still have had tool calls
rejected along the way. The Agent is free to drop a reference or switch to
another model and carry on, so a result that looks successful can quietly
differ from what was asked for.
The result carries a failures array whenever that happens:
{
"final_status": "done",
"generation_succeeded": true,
"warning": "2 tool calls were rejected. generate_video_seedance_v2_0_fast was rejected: ...",
"failures": [
{
"tool": "generate_media",
"tool_hint": "generate_video_seedance_v2_0_fast",
"code": "SEEDANCE_ASSET_MODERATION_REJECTED",
"message": "1 reference asset(s) failed content moderation. Do not retry with the same asset(s); replace them with compliant assets."
},
{
"tool": "generate_media",
"tool_hint": "generate_video_minimax_h3",
"code": "INPUT_PARAMS_INVALID",
"message": "MiniMax H3 resolution must be 768P or 2K."
}
]
}
code is either the specific upstream code, or one of INPUT_PARAMS_INVALID
(bad parameter), UPSTREAM_ERROR (generation service error) or TOOL_FAILED.
Always read failures before telling the user the run succeeded. When it is
non-empty, tell them what was refused and why. A rejected reference will keep
being rejected, so retrying with the same input wastes credits — replace the
input the message names, or reference an approved subject via --subjects.
--mode thinking / --mode fastLovart has two reasoning modes you can select per thread:
fast (default) — lightweight single-pass response. Use for simple, one-shot generations where speed matters.thinking — deep structured reasoning with planning and multi-step analysis. Use for complex brand systems, multi-asset campaigns, anything that benefits from deliberate planning. Slower but higher quality.Omitting --mode is equivalent to --mode fast, matching the web UI's default.
# Thinking mode — strategic, multi-step
python3 {baseDir}/scripts/agent_skill.py chat --prompt "design a brand identity system for a sustainable coffee startup" --mode thinking --json --download
# Fast mode — quick one-shot
python3 {baseDir}/scripts/agent_skill.py chat --prompt "draw a cat" --mode fast --json --download
Mode is locked to the thread on its first message. Once you start a thread with --mode thinking, subsequent messages on the same --thread-id stay in thinking mode regardless of later --mode flags. To switch modes, start a new thread (omit --thread-id).
When the user's request matches a specific operation, use --include-tools to ensure the correct tool:
| User says | Use --include-tools |
|---|---|
| "upscale", "放大", "enlarge", "enhance resolution", "超分" | upscale_image |
| "edit image", "modify", "change style" | (let Agent decide) |
| "generate image", "draw", "画" | (let Agent decide, or use --prefer-models) |
CRITICAL: When the user asks to "upscale", "enlarge", or increase resolution of an existing image, you MUST use --include-tools upscale_image. Do NOT let the Agent use image generation models for upscaling — they will re-generate the image instead of upscaling it.
