⚠️ 重要：模型 ID 参考

CRITICAL: When calling the script, you MUST use the exact model_id (second column), NOT the friendly model name. Do NOT infer model_id from the friendly name (e.g., ❌

nano-banana-pro

gemini-3-pro-image

How to get the correct model_id:

1. Check this table first
2. Use

   --list-models --task-type <type>

   to query available models
3. Refer to command examples in this SKILL.md

Runtime truth source:

GET /open/v1/product/list

(or

--list-models

).
Any table in this document is guidance; actual availability depends on current product list.

Example:

# ❌ WRONG: Inferring from friendly name
--model-id nano-banana-pro

# ✅ CORRECT: Using exact model_id from table
--model-id gemini-3-pro-image

📚 Optional Knowledge Enhancement (ima-knowledge-ai)

This skill is fully runnable as a standalone package. If

ima-knowledge-ai

Recommended optional reads:

1. Check for workflow complexity — Read

   ima-knowledge-ai/references/workflow-design.md

   if:
   • User mentions: "MV"、"宣传片"、"完整作品"、"配乐"、"soundtrack"
   • Task spans multiple media types (image + video, video + music, etc.)
   • Complex multi-step workflows that need task decomposition

2. Check for visual consistency needs — Read

   ima-knowledge-ai/references/visual-consistency.md

   if:
   • User mentions: "系列"、"多张"、"同一个"、"角色"、"续"、"series"、"same"
   • Task involves: multiple images/videos, character continuity, product shots
   • Second+ request about same subject (e.g., "旺财在游泳" after "生成旺财照片")

3. Check video modes — Read

   ima-knowledge-ai/references/video-modes.md

   if:
   • Any video generation task
   • Need to understand: image_to_video vs reference_image_to_video difference

4. Check model selection — Read

   ima-knowledge-ai/references/model-selection.md

   if:
   • Unsure which model to use
   • Need cost/quality trade-off guidance
   • User specifies budget or quality requirements

Why this matters:

• Multi-media workflows need proper task sequencing (e.g., video duration → matching music duration)
• AI generation defaults to 独立生成 each time — without reference images, results will be inconsistent
• Wrong video mode = wrong result (image_to_video ≠ reference_image_to_video)
• Model choice affects cost and quality significantly

Example multi-media workflow:

User: "帮我做个产品宣传MV，有背景音乐，主角是旺财小狗"

❌ Wrong: 
  1. Generate dog image (random look)
  2. Generate video (different dog)
  3. Generate music (unrelated)

✅ Right:
  1. Read workflow-design.md + visual-consistency.md
  2. Generate Master Reference: 旺财小狗图片
  3. Generate video shots using image_to_video with 旺财 as first frame
  4. Get video duration (e.g., 15s)
  5. Generate BGM with matching duration and mood

How to check:

# Step 0: Determine media type first (image / video / music / speech)
# From user request: "画"/"生成图"/"image" → image; "视频"/"video" → video; "音乐"/"歌"/"music"/"BGM" → music; "语音"/"朗读"/"TTS"/"speech" → speech
# Then choose task_type and model from the corresponding section (image: text_to_image/image_to_image; video: text_to_video/...; music: text_to_music; speech: text_to_speech)

# Step 1: Read knowledge base based on task type
if multi_media_workflow:
    read("~/.openclaw/skills/ima-knowledge-ai/references/workflow-design.md")

if "same subject" or "series" or "character":
    read("~/.openclaw/skills/ima-knowledge-ai/references/visual-consistency.md")

if video_generation:
    read("~/.openclaw/skills/ima-knowledge-ai/references/video-modes.md")

# Step 2: Execute with proper sequencing and reference images
# (see workflow-design.md for specific patterns)

No exceptions — for simple single-media requests, you can proceed directly. For complex multi-media workflows, read the knowledge base first.

📥 User Input Parsing (Media Type & Task Routing)

Purpose: So that any agent parses user intent consistently, first determine the media type from the user's request, then choose task_type and model.

1. User phrasing → media type (do this first)

text_to_image

image_to_image

text_to_video

image_to_video

first_last_frame_to_video

reference_image_to_video

text_to_music

text_to_speech

If the request mixes media (e.g. "宣传片+配乐"), treat as multi-media workflow: read

workflow-design.md

2. Model and parameter parsing

• Image: For model name → model_id and size/aspect_ratio parsing, follow the same rules as in ima-image-ai skill (User Input Parsing section).

• Video: For task_type (t2v / i2v / first_last / reference), model alias → model_id, and duration/resolution/aspect_ratio, follow ima-video-ai skill (User Input Parsing section).
  Sevio alias normalization in

  ima-all-ai

  :

  • Ima Sevio 1.0

    →

    ima-pro

  • Ima Sevio 1.0-Fast

    /

    Ima Sevio 1.0 Fast

    →

    ima-pro-fast

    Routing rule:
  • Normalize alias first
  • Then resolve against runtime product list for the selected

    task_type

  • If model is absent in current category, return available model_ids from

    --list-models

• Music: Suno (

  sonic

  ) vs DouBao BGM/Song — infer from "BGM"/"背景音乐" → BGM; "带歌词"/"人声" → Suno or Song. Use model_id

  sonic

  ,

  GenBGM

  ,

  GenSong

  per "Recommended Defaults" and "Music Generation" tables below.

• Speech (TTS): Get model_id from

  GET /open/v1/product/list?category=text_to_speech

  or run script with

  --task-type text_to_speech --list-models

  . Map user intent to parameters using product

  form_config

  :

  User intent / phrasing	Parameter (if in form_config)	Notes
  女声 / 女声朗读 / female voice	voice_id / voice_type	Use value from form_config options
  男声 / 男声朗读 / male voice	voice_id / voice_type	Use value from form_config options
  语速快/慢 / speed up/slow	speed	e.g. 0.8–1.2
  音调 / pitch	pitch	If supported
  大声/小声 / volume	volume	If supported

  If the user does not specify, use form_config defaults. Pass extra params via

  --extra-params '{"speed":1.0}'

  . Only send parameters present in the product’s credit_rules/attributes or form_config (script reflection strips others on retry).

⚙️ How This Skill Works

For transparency: This skill uses a bundled Python script (

scripts/ima_create.py

• Sends your prompt to two IMA-owned domains (see "Network Endpoints" below)
• Uses

  --user-id

  only locally as a key for storing your model preferences
• Returns image/video/music URLs when generation is complete

What gets sent to IMA servers:

• ✅ Your prompt/description (image/video/music)
• ✅ Model selection (SeeDream/Wan/Suno/etc.)
• ✅ Generation parameters (size, duration, style, etc.)
• ❌ NO API key in prompts (key is used for authentication only)
• ❌ NO user_id (it's only used locally)

What's stored locally:

• ~/.openclaw/memory/ima_prefs.json

  - Your model preferences (< 1 KB)

• ~/.openclaw/logs/ima_skills/

  - Generation logs (auto-deleted after 7 days)

🌐 Network Endpoints Used

api.imastudio.com

imapi.liveme.com

*.aliyuncs.com

*.esxscloud.com

Key Points:

• Music tasks (

  text_to_music

  ) and TTS tasks (

  text_to_speech

  ) only use

  api.imastudio.com

  .
• Image/video tasks require

  imapi.liveme.com

  to obtain presigned URLs for uploading input images.
• Your API key is sent to both

  api.imastudio.com

  and

  imapi.liveme.com

  (both owned by IMA Studio).
• Verify network calls:

  tcpdump -i any -n 'host api.imastudio.com or host imapi.liveme.com'

  . See this document: 🌐 Network Endpoints Used and ⚠️ Credential Security Notice for full disclosure.

⚠️ Credential Security Notice

Your API key is sent to both IMA-owned domains:

1. Authorization: Bearer ima_xxx...

   →

   api.imastudio.com

   (main API)
2. Query param

   appUid=ima_xxx...

   →

   imapi.liveme.com

   (upload service)

Security best practices:

• 🧪 Use test keys for experiments: Generate a separate API key for testing.
• 🔍 Monitor usage: Check

  https://imastudio.com/dashboard

  for unauthorized activity.
• ⏱️ Rotate keys: Regenerate your API key periodically (monthly recommended).
• 📊 Review logs: Check

  ~/.openclaw/logs/ima_skills/

  for unexpected API calls.

Why two domains? IMA Studio uses a microservices architecture:

• api.imastudio.com

  : Core AI generation API

• imapi.liveme.com

  : Specialized image/video upload service (shared infrastructure)

Both domains are operated by IMA Studio. The same API key grants access to both services.

Agent Execution (Internal Reference)

Note for users: You can review the script source at

scripts/ima_create.py

anytime.
The agent uses this script to simplify API calls. Music tasks use only

api.imastudio.com

, while image/video tasks also call

imapi.liveme.com

for file uploads (see "Network Endpoints" above).

Use the bundled script internally for all task types — it ensures correct parameter construction:

🔒 Security & Transparency Policy

This skill is community-maintained and open for inspection.

✅ What Users CAN Do

Full transparency:

• ✅ Review all source code: Check

  scripts/ima_create.py

  and

  ima_logger.py

  anytime
• ✅ Verify network calls: Music tasks use

  api.imastudio.com

  only; image/video tasks also use

  imapi.liveme.com

  (see "Network Endpoints" section)
• ✅ Inspect local data: View

  ~/.openclaw/memory/ima_prefs.json

  and log files
• ✅ Control privacy: Delete preferences/logs anytime, or disable file writes (see below)

Configuration allowed:

• ✅ Set API key in environment or agent config:
  • Environment variable:

    export IMA_API_KEY=ima_your_key_here

  • OpenClaw/MCP config: Add

    IMA_API_KEY

    to agent's environment configuration
  • Get your key at: https://imastudio.com
• ✅ Use scoped/test keys: Test with limited API keys, rotate after testing
• ✅ Disable file writes: Make prefs/logs read-only or symlink to

  /dev/null

Data control:

• ✅ View stored data:

  cat ~/.openclaw/memory/ima_prefs.json

• ✅ Delete preferences:

  rm ~/.openclaw/memory/ima_prefs.json

⚠️ Advanced Users: Fork & Modify

If you need to modify this skill for your use case:

1. Fork the repository (don't modify the original)
2. Update your fork with your changes
3. Test thoroughly with limited API keys
4. Document your changes for troubleshooting

Note: Modified skills may break API compatibility or introduce security issues. Official support only covers the unmodified version.

❌ What to AVOID (Security Risks)

Actions that could compromise security:

• ❌ Sharing API keys publicly or in skill files
• ❌ Modifying API endpoints to unknown servers
• ❌ Disabling SSL/TLS certificate verification
• ❌ Logging sensitive user data (prompts, IDs, etc.)
• ❌ Bypassing authentication or billing mechanisms

Why this matters:

1. API Compatibility: Skill logic aligns with IMA Open API schema
2. Security: Malicious modifications could leak credentials or bypass billing
3. Support: Modified skills may not be supported
4. Community: Breaking changes affect all users

📋 Privacy & Data Handling Summary

What this skill does with your data:

--user-id

Privacy recommendations:

1. Use test/scoped API keys for initial testing
2. Note:

   --user-id

   is never sent to IMA servers - it's only used locally as a key for storing preferences in

   ~/.openclaw/memory/ima_prefs.json

3. Review source code at

   scripts/ima_create.py

   to verify network calls (search for

   create_task

   function)
4. Rotate API keys after testing or if compromised

🔧 For Skill Maintainers Only

Version control:

• All changes must go through Git with proper version bumps (semver)
• CHANGELOG.md must document all changes
• Production deployments require code review

File checksums (optional):

# Verify skill integrity
sha256sum SKILL.md scripts/ima_create.py

If users report issues, verify file integrity first.

🧠 User Preference Memory (Image)

User preferences have highest priority when they exist. But preferences are only saved when users explicitly express model preferences — not from automatic model selection.

Storage:

~/.openclaw/memory/ima_prefs.json

Single file, shared across all IMA skills:

{
  "user_{user_id}": {
    "text_to_image":  { "model_id": "doubao-seedream-4.5", "model_name": "SeeDream 4.5", "credit": 5,  "last_used": "2026-02-27T03:07:27Z" },
    "image_to_image": { "model_id": "doubao-seedream-4.5", "model_name": "SeeDream 4.5", "credit": 5,  "last_used": "2026-02-27T03:07:27Z" },
    "text_to_speech": { "model_id": "<from product list>", "model_name": "...", "credit": 2, "last_used": "..." }
  }
}

Model Selection Flow (Image Generation)

Step 1: Get knowledge-ai recommendation (if installed)

knowledge_recommended_model = read_ima_knowledge_ai()  # e.g., "SeeDream 4.5"

Step 2: Check user preference

user_pref = load_prefs().get(f"user_{user_id}", {}).get(task_type)  # e.g., {"model_id": "midjourney", ...}

Step 3: Decide which model to use

if user_pref exists:
    use_model = user_pref["model_id"]  # Highest priority
else:
    use_model = knowledge_recommended_model or fallback_default

Step 4: Check for mismatch (for later hint)

if user_pref exists and knowledge_recommended_model != user_pref["model_id"]:
    mismatch = True  # Will add hint in success message

When to Write (User Explicit Preference ONLY)

✅ Save preference when user explicitly specifies a model:

用XXX

换成XXX

改用XXX

以后都用XXX

默认用XXX

always use XXX

✅ 已记住！以后图片生成默认用 [XXX]

我喜欢XXX

我更喜欢XXX

❌ Do NOT save when:

• Agent auto-selects from knowledge-ai → not user preference
• Agent uses fallback default → not user preference
• User says generic quality requests (see "Clear Preference" below) → clear preference instead

When to Clear (User Abandons Preference)

🗑️ Clear preference when user wants automatic selection:

用最好的

用最合适的

best

recommended

推荐一个

你选一个

自动选择

用默认的

用新的

试试别的

换个试试

重新推荐

Implementation:

del prefs[f"user_{user_id}"][task_type]
save_prefs(prefs)

⭐ Model Selection Priority (Image)

Selection flow:

1. User preference (if exists) → Highest priority, always respect
2. ima-knowledge-ai skill (if installed) → Professional recommendation based on task
3. Fallback defaults → Use table below (only if neither 1 nor 2 exists)

Important notes:

• User preference is only saved when user explicitly specifies a model (see "When to Write" above)
• Knowledge-ai is always consulted (even when user pref exists) to detect mismatches
• When mismatch detected → add gentle hint in success message (does NOT interrupt generation)

The defaults below are FALLBACK only. User preferences have highest priority, then knowledge-ai recommendations.

When using user preference for image generation, show a line like:

🎨 根据你的使用习惯，将用 [Model Name] 帮你生成…
• 模型：[Model Name]（你的常用模型）
• 预计耗时：[X ~ Y 秒]
• 消耗积分：[N pts]

Preference Change Confirmation

When user switches to a different model than their saved preference:

💡 你之前喜欢用 [Old Model]，这次换成了 [New Model]。
要把 [New Model] 设为以后的默认吗？
回复「是」保存 / 回复「否」仅本次使用

⭐ Recommended Defaults

These are fallback defaults — only used when no user preference exists.
Always default to the newest and most popular model. Do NOT default to the cheapest.

🆕 Special Case: Pixverse Model Parameter (v1.0.7+)

Auto-Inference Logic for Pixverse V5.5/V5/V4:

• Problem: Pixverse V5.5, V5, V4 lack

  model

  field in

  form_config

  from Product List API
• Backend Requirement: Backend requires

  model

  parameter (e.g.,

  "v5.5"

  ,

  "v5"

  ,

  "v4"

  )
• Auto-Fix: System automatically extracts version from

  model_name

  and injects it
  • Example:

    model_name: "Pixverse V5.5"

    → auto-inject

    model: "v5.5"

  • Example:

    model_name: "Pixverse V4"

    → auto-inject

    model: "v4"

• Note: V4.5 and V3.5 include

  model

  in

  form_config

  (no auto-inference needed)
• Relevant Task Types: All video modes (text_to_video, image_to_video, first_last_frame_to_video, reference_image_to_video)

Error Prevention:

• Without auto-inference:

  err_code=400017 err_msg=Invalid value for model

• With auto-inference (v1.0.7+): Pixverse V5.5/V5/V4 work seamlessly ✅

🎵 Suno Prompt Writing Guide (for

gpt_description_prompt

When using Suno, structure your prompt with these elements:

1. Genre/Style:

   • Examples:

     "lo-fi hip hop"

     ,

     "orchestral cinematic"

     ,

     "upbeat pop"

     ,

     "dark ambient"

     ,

     "indie folk"

     ,

     "electronic dance"

2. Tempo/BPM:

   • Examples:

     "80 BPM"

     ,

     "fast tempo"

     ,

     "slow ballad"

     ,

     "moderate pace 110 BPM"

3. Vocals Control:

   • No vocals:

     "no vocals"

     → set

     make_instrumental=true

   • With vocals:

     "female vocals"

     → set

     vocal_gender="female"

   • Male vocals:

     "male vocals"

     → set

     vocal_gender="male"

   • Mixed: Set

     vocal_gender="mixed"

4. Mood/Emotion:

   • Examples:

     "happy and energetic"

     ,

     "melancholic"

     ,

     "tense and dramatic"

     ,

     "peaceful and calming"

5. Negative Tags (exclude styles):

   • Use

     negative_tags

     :

     "heavy metal, distortion, screaming"

     to exclude unwanted elements

6. Duration Hint:

   • Examples:

     "60 seconds"

     ,

     "30 second loop"

     ,

     "2 minute track"

   • Note: Suno typically generates ~2min, not strictly controllable

Example Suno prompts:

"upbeat lo-fi hip hop, 90 BPM, no vocals, relaxed and chill"
→ Set: make_instrumental=true

"emotional pop ballad, slow tempo, female vocals, melancholic"
→ Set: vocal_gender="female"

"orchestral cinematic trailer music, epic and dramatic, 120 BPM, no vocals"
→ Set: make_instrumental=true, tags="orchestral,cinematic,epic"

"acoustic indie folk, gentle guitar, male vocals, warm and nostalgic"
→ Set: vocal_gender="male", tags="acoustic,indie,folk"

⚠️ Technical Note for Suno:

model_version

inside

parameters.parameters

(e.g.,

"sonic-v5"

) is different from the outer

model_version

field (which is

"sonic"

). Always set both correctly.

Common Parameter Patterns

• n (batch generation): Supported by ALL models. Cost = base_credit × n. Creates n independent resources.
• seed: Supported by most models (-1 = random, >0 = reproducible results)
• prompt_extend: AI-powered prompt enhancement (video models only)

Decision Tree: When User Requests Unsupported Features

User asks for custom aspect ratio image (e.g. "7:3 landscape")
  → ❌ Image models don't support custom ratios
  → ✅ Solution: "图片模型不支持自定义比例。建议用视频模型(Wan 2.6 t2v)生成16:9视频，然后截取首帧作为图片。"

User asks for 8K image
  → ❌ No model supports 8K
  → ✅ Solution: "当前最高支持4K分辨率(Nano Banana Pro，18积分)。要使用吗？"

User asks for video with audio
  → Check model: Veo 3.1 / Kling O1 / Hailuo have generate_audio
  → ✅ Solution: "Veo 3.1 和 Kling O1 支持音频生成(需在参数中设置 generate_audio=True)。要用哪个？"

User asks for long music (e.g. "5 minute track")
  → ❌ Duration not user-controllable
  → ✅ Solution: "Suno 生成约2分钟音乐。需要更长时长可以生成多段后拼接。"

User asks for 30s video
  → Check model: Most models max 15s
  → ✅ Solution: "当前最长15秒。可选模型：Wan 2.6(15s, 75积分), Kling O1(10s, 96积分)。"

When user requests unsupported combinations:

• Video + audio (unsupported model) → "该模型不支持音频。建议用 Veo 3.1 或 Kling O1 (支持 generate_audio 参数)"
• Music + custom duration → "音乐时长由模型固定(Suno约2分钟,DouBao约30秒),无法自定义"
• Video duration > 15s → "当前最长15秒。可选模型：Wan 2.6(15s, 75积分), Kling O1(10s, 96积分)"

Note: Image-specific unsupported combinations (Midjourney + aspect_ratio, 8K, non-standard ratios) are documented in the "Image Models" section above.

🧠 User Preference Memory (Video)

User preferences have highest priority when they exist. But preferences are only saved when users explicitly express model preferences — not from automatic model selection.

Storage:

~/.openclaw/memory/ima_prefs.json

{
  "user_{user_id}": {
    "text_to_video":              { "model_id": "wan2.6-t2v",      "model_name": "Wan 2.6",  "credit": 25, "last_used": "..." },
    "image_to_video":             { "model_id": "wan2.6-i2v",      "model_name": "Wan 2.6",  "credit": 25, "last_used": "..." },
    "first_last_frame_to_video":  { "model_id": "kling-video-o1", "model_name": "Kling O1", "credit": 48, "last_used": "..." },
    "reference_image_to_video":   { "model_id": "kling-video-o1", "model_name": "Kling O1", "credit": 48, "last_used": "..." }
  }
}

Model Selection Flow (Video Generation)

Step 1: Get knowledge-ai recommendation (if installed)

knowledge_recommended_model = read_ima_knowledge_ai()  # e.g., "Wan 2.6"

Step 2: Check user preference

user_pref = load_prefs().get(f"user_{user_id}", {}).get(task_type)  # e.g., {"model_id": "kling-video-o1", ...}

Step 3: Decide which model to use

if user_pref exists:
    use_model = user_pref["model_id"]  # Highest priority
else:
    use_model = knowledge_recommended_model or fallback_default

Step 4: Check for mismatch (for later hint)

if user_pref exists and knowledge_recommended_model != user_pref["model_id"]:
    mismatch = True  # Will add hint in success message

When to Write (User Explicit Preference ONLY)

✅ Save preference when user explicitly specifies a model:

用XXX

换成XXX

改用XXX

以后都用XXX

默认用XXX

always use XXX

✅ 已记住！以后视频生成默认用 [XXX]

我喜欢XXX

我更喜欢XXX

❌ Do NOT save when:

• Agent auto-selects from knowledge-ai → not user preference
• Agent uses fallback default → not user preference
• User says generic quality requests (see "Clear Preference" below) → clear preference instead

When to Clear (User Abandons Preference)

🗑️ Clear preference when user wants automatic selection:

用最好的

用最合适的

best

recommended

推荐一个

你选一个

自动选择

用默认的

用新的

试试别的

换个试试

重新推荐

Implementation:

del prefs[f"user_{user_id}"][task_type]
save_prefs(prefs)

⭐ Model Selection Priority (Video)

Selection flow:

1. User preference (if exists) → Highest priority, always respect
2. ima-knowledge-ai skill (if installed) → Professional recommendation based on task
3. Fallback defaults → Use table below (only if neither 1 nor 2 exists)

Important notes:

• User preference is only saved when user explicitly specifies a model (see "When to Write" above)
• Knowledge-ai is always consulted (even when user pref exists) to detect mismatches
• When mismatch detected → add gentle hint in success message (does NOT interrupt generation)

The defaults below are FALLBACK only. User preferences have highest priority, then knowledge-ai recommendations.

💬 User Experience Protocol (IM / Feishu / Discord) v2.0 🆕

v2.0 Updates (aligned with ima-image-ai v1.3):

• Added Step 0 for correct message ordering (fixes group chat bug)
• Added Step 5 for explicit task completion
• Enhanced Midjourney support with proper timing estimates
• Now 6 steps total (0-5): Acknowledgment → Pre-Gen → Progress → Success/Failure → Done

This skill runs inside IM platforms (Feishu, Discord via OpenClaw).
Generation takes 10 seconds (music) up to 6 minutes (video). Never let users wait in silence.
Always follow all 6 steps below, every single time.

🗣️ User-Friendly First, Transparent on Request

Default to plain-language updates in normal user flows. If users ask for technical details, provide them transparently (script name, endpoints, and key parameters).

In standard progress messages, prioritize: model name, estimated/actual time, credits consumed, result URL, and natural-language status updates.

Estimated Generation Time (All Task Types)

estimated_max_seconds

Step 0 — Initial Acknowledgment Reply (Normal Reply) 🆕

⚠️ CRITICAL: This step is essential for correct message ordering in IM platforms (Feishu, Discord).

Before doing anything else, reply to the user with a friendly acknowledgment message using your normal reply (not

message

Example acknowledgment messages:

For images:

好的!来帮你画一只萌萌的猫咪 🐱

收到！马上为你生成一张 16:9 的风景照 🏔️

OK! Starting image generation with SeeDream 4.5 🎨

For videos:

好的!来帮你生成一段视频 🎬

收到！开始用 Wan 2.6 生成视频 🎥

For music:

好的!来帮你创作一首音乐 🎵

Rules:

• Keep it short and warm (< 15 words)
• Match the user's language (Chinese/English)
• Include relevant emoji (🐱/🎨/🎬/🎵/✨)
• This is your ONLY normal reply — all subsequent updates use

  message

  tool

Why this matters:

• Normal replies automatically appear FIRST in the conversation thread

• message

  tool pushes appear in chronological order AFTER your initial reply
• This ensures users see: "好的!" → "🎨 开始生成..." → "⏳ 进度..." → "✅ 成功!" (correct order)
• Without Step 0, the confirmation might appear LAST, confusing users

Step 1 — Pre-Generation Notification (Push via message tool)

After Step 0 reply, use the

message

[Emoji] 开始生成 [内容类型]，请稍候…
• 模型：[Model Name]
• 预计耗时：[X ~ Y 秒]
• 消耗积分：[N pts]

Emoji by content type:

• 图片 →

  🎨

• 视频 →

  🎬

  （加注:视频生成需要较长时间，我会定时汇报进度）
• 音乐 →

  🎵

Cost transparency (new requirement):

• Always show credit cost with model tier context
• For expensive models (>50 pts), offer cheaper alternative proactively
• Examples:
  • Balanced (default): "使用 Wan 2.6（25 积分，最新 Wan）"
  • Premium (user explicit): "使用高端模型 Kling O1（48-120 积分），质量最佳"
  • Premium (auto-selected): "使用 Wan 2.6（25 积分）。若需更高质量可选 Kling O1（48 积分起）"
  • Budget (user asked): "使用 Vidu Q2（5 积分，最省钱）"

Adapt language to match the user (Chinese / English). For video, always add a note that it takes longer. For expensive models, always mention cheaper alternatives unless user explicitly requested premium.

Step 2 — Progress Updates

Poll the task detail API every

[Poll Every]

[Send Progress Every]

⏳ 正在生成中… [P]%
已等待 [elapsed]s，预计最长 [max]s

Progress formula:

P = min(95, floor(elapsed_seconds / estimated_max_seconds * 100))

• Cap at 95% — never reach 100% until the API confirms

  success

• If

  elapsed > estimated_max

  : freeze at 95%, append

  「快了，稍等一下…」

• For video with max=360s: at 120s → 33%, at 250s → 69%, at 400s → 95% (frozen)

Step 3 — Success Notification

When task status =

success

For Video Tasks (text_to_video / image_to_video / first_last_frame / reference_image)

3.1 Send video player first (IM platforms like Feishu will render inline player):

# Get result URL from script output or task detail API
result = get_task_result(task_id)
video_url = result["medias"][0]["url"]

# Build caption
caption = f"""✅ 视频生成成功！
• 模型：[Model Name]
• 耗时：预计 [X~Y]s，实际 [actual]s
• 消耗积分：[N pts]

[视频描述]"""

# Add mismatch hint if user pref conflicts with knowledge-ai recommendation
if user_pref_exists and knowledge_recommended_model != used_model:
    caption += f"""

💡 提示：当前任务也许用 {knowledge_recommended_model} 也会不错（{reason}，{cost} pts）"""

# Send video with caption (use message tool if available)
message(
    action="send",
    media=video_url,  # ⚠️ Use HTTPS URL directly, NOT local file path
    caption=caption
)

Important:

• Hint is non-intrusive — does NOT interrupt generation
• Only shown when user pref conflicts with knowledge-ai recommendation
• User can ignore the hint; video is already delivered

3.2 Then send link as text (for copying/sharing):

# Send link message immediately after video
message(action="send", text=f"🔗 视频链接（可复制分享）：\n{video_url}")

⚠️ Critical for video:

• Send video player FIRST (inline preview)
• Send text link SECOND (for copying)
• Include first-frame thumbnail URL if available:

  result["medias"][0]["cover"]

For Image Tasks (text_to_image / image_to_image)

# Build caption
caption = f"""✅ 图片生成成功！
• 模型：[Model Name]
• 耗时：预计 [X~Y]s，实际 [actual]s
• 消耗积分：[N pts]

🔗 原始链接：{image_url}"""

# Add mismatch hint if user pref conflicts with knowledge-ai recommendation
if user_pref_exists and knowledge_recommended_model != used_model:
    caption += f"""

💡 提示：当前任务也许用 {knowledge_recommended_model} 也会不错（{reason}，{cost} pts）"""

# Send image with caption
message(
    action="send",
    media=image_url,
    caption=caption
)

Important:

• Hint is non-intrusive — does NOT interrupt generation
• Only shown when user pref conflicts with knowledge-ai recommendation
• User can ignore the hint; image is already delivered

For Music Tasks (text_to_music)

Send audio file with player:

✅ 音乐生成成功！
• 模型：[Model Name]
• 耗时：预计 [X~Y]s，实际 [actual]s
• 消耗积分：[N pts]
• 时长：约 [duration]

[音频URL或直接发送音频文件]

For TTS Tasks (text_to_speech) — Full UX Protocol (Steps 0–5)

Step 0 — Initial acknowledgment (normal reply)
First reply with a short acknowledgment, e.g.: 好的，正在帮你把这段文字转成语音。 / OK, converting this text to speech.

Step 1 — Pre-generation (message tool)
Push once:

🔊 开始语音合成，请稍候…
• 模型：[Model Name]
• 预计耗时：[X ~ Y 秒]
• 消耗积分：[N pts]

Step 2 — Progress
Poll every 2–5s. Every 10–15s send:

⏳ 语音合成中… [P]%

Step 3 — Success (message tool)
When

resource_status == 1

status != "failed"

medias[0].url

✅ 语音合成成功！
• 模型：[Model Name]
• 耗时：实际 [actual]s
• 消耗积分：[N pts]
🔗 原始链接：[url]

Use the URL from the API (do not use local file paths).

Step 4 — Failure (message tool)
On failure, send user-friendly message. TTS error translation (do not expose raw API errors):

Links: API key — https://www.imaclaw.ai/imaclaw/apikey ；Credits — https://www.imaclaw.ai/imaclaw/subscription

Step 5 — Done
After Step 0–4, no further reply needed. Do not send duplicate confirmations.

Step 4 — Failure Notification

When task status =

failed

❌ [内容类型]生成失败
• 原因：[natural_language_error_message]
• 建议改用：
  - [Alt Model 1]（[特点]，[N pts]）
  - [Alt Model 2]（[特点]，[N pts]）

需要我帮你用其他模型重试吗？

⚠️ CRITICAL: Error Message Translation

NEVER show technical error messages to users. Always translate API errors into natural language.
API key & credits: 密钥与积分管理入口为 imaclaw.ai（与 imastudio.com 同属 IMA 平台）。Key and subscription management: imaclaw.ai (same IMA platform as imastudio.com).

401 Unauthorized

4008 Insufficient points

"Invalid product attribute"

"Insufficient points"

Error 6006

Error 6009

Error 6010

error 400

resource_status == 2

status == "failed"

timeout

Generic fallback (when error is unknown):

• Chinese:

  生成过程遇到问题，请稍后重试或换个模型试试

• English:

  Generation encountered an issue, please try again or use another model

Best Practices:

1. Focus on user action: Tell users what to do next, not what went wrong technically
2. Be reassuring: Use phrases like "建议换个模型试试" instead of "失败了"
3. Avoid blame: Never say "你的提示词有问题" → say "提示词需要调整一下"
4. Provide alternatives: Always suggest 1-2 alternative models in the failure message
5. 🆕 Include actionable links (v1.0.8+): For 401/4008 errors, provide clickable links to API key generation or credit purchase pages
6. 🎵 Music-specific (v1.2.0+):
   • For Suno lyrics errors, suggest simplifying lyrics or using auto-generated lyrics (

     auto_lyrics=true

     )
   • For prompt length errors, give example length (e.g., "建议20-100字")
   • For BGM requests, recommend DouBao BGM over Suno
7. 🔊 TTS-specific: Use the TTS error translation table in "For TTS Tasks (text_to_speech)" above; suggest another model via

   --list-models

   or shortening text.

Step 5 — Done (No Further Action Needed) 🆕

After sending Step 3 (success) or Step 4 (failure):

1. DO NOT send any additional messages unless the user asks a follow-up question
2. The task is complete — wait for the user's next request
3. User preference has been saved (if generation succeeded)
4. The conversation is ready for the next generation request

Why this step matters:

• Prevents unnecessary "anything else?" messages that clutter the chat
• Allows users to naturally continue the conversation when ready
• Respects the asynchronous nature of IM platforms

Exception: If the user explicitly asks "还有别的吗？" or similar, then respond naturally.

🆕 Enhanced Error Handling (v1.0.8):

The Reflection mechanism (3 automatic retries) now provides specific, actionable suggestions for common errors:

• 401 Unauthorized: System suggests generating a new API key with clickable link
• 4008 Insufficient Points: System suggests purchasing credits with clickable link
• 500 Internal Server Error: Automatic parameter degradation (size, resolution, duration, quality)
• 6009 No Rule Match: Automatic parameter completion from credit_rules
• 6010 Attribute Mismatch: Automatic credit_rule reselection
• Timeout: Helpful info with dashboard link for background task status

All error handling is automatic and transparent — users receive natural language explanations with next steps.

Failure fallback by task type:

--list-models

Music-specific failure guidance:

• If Suno fails → Recommend DouBao BGM (for background music) or DouBao Song (for songs)
• If DouBao BGM fails → Try DouBao Song first (similar pricing), then Suno (more powerful)
• If DouBao Song fails → Try DouBao BGM first (similar pricing), then Suno (more powerful)
• For lyrics errors in Suno → Suggest simplifying lyrics or using

  auto_lyrics=true

• For prompt length errors → Recommend 20-100 characters

TTS-specific failure guidance:

• If TTS fails → Run

  --task-type text_to_speech --list-models

  and suggest another model_id; or shorten text / simplify content. Use the TTS error translation table in "For TTS Tasks" above for user-facing messages.

📤 When to Upload Images (Quick Reference)

The IMA Open API does NOT accept raw bytes or base64 images. All image inputs must be public HTTPS URLs.

Upload flow:

1. User provides local file path or bytes → call

   prepare_image_url()

   (see section below)
2. User provides HTTPS URL → use directly, no upload needed
3. Use the returned CDN URL (

   fdl

   ) as the value for

   input_images

   /

   src_img_url

Example workflow (image_to_image):

# User provides local file
image_url = prepare_image_url("/path/to/photo.jpg", api_key)
# → Returns: https://ima-ga.esxscloud.com/webAgent/privite/2026/02/27/..._uuid.jpeg

# Then create task with this URL
create_task(
    task_type="image_to_image",
    input_images=[image_url],  # Use uploaded URL
    prompt="turn into oil painting"
)

⚠️ MANDATORY: Always Query Product List First

CRITICAL: You MUST call

/open/v1/product/list

BEFORE creating any task.
The

attribute_id

field is REQUIRED in the create request. If it is

0

or missing, you get:

"Invalid product attribute"

→

"Insufficient points"

→ task fails completely.
NEVER construct a create request from the model table alone. Always fetch the product first.

How to get attribute_id (all task types)

# Query product list with the correct category
GET /open/v1/product/list?app=ima&platform=web&category=<task_type>
# task_type: text_to_image | image_to_image | text_to_video | image_to_video |
#            first_last_frame_to_video | reference_image_to_video | text_to_music | text_to_speech

# Walk the V2 tree to find your target model (type=3 leaf nodes only)
for group in response["data"]:
    for version in group.get("children", []):
        if version["type"] == "3" and version["model_id"] == target_model_id:
            attribute_id  = version["credit_rules"][0]["attribute_id"]
            credit        = version["credit_rules"][0]["points"]
            model_version = version["id"]    # = version_id / model_version
            model_name    = version["name"]
            form_defaults = {f["field"]: f["value"] for f in version["form_config"]}
            break

Quick Reference: Known attribute_ids

Pre-queried values for convenience. Always call the product list at runtime for accuracy.

The script automatically selects the correct

attribute_id

duration

resolution

compression_quality

generate_audio

Fix: The bundled script now checks these video-specific parameters for smart credit_rule selection. Always use the script, not manual API construction.

Core Flow

1. GET /open/v1/product/list?app=ima&platform=web&category=<type>
   → REQUIRED: Get attribute_id, credit, model_version, model_name, form_config defaults

[If input image required]
2. Upload image → get public HTTPS URL
   → See "Image Upload" section below

3. POST /open/v1/tasks/create
   → Must include: attribute_id, model_name, model_version, credit, cast, prompt (nested!)

4. POST /open/v1/tasks/detail  {"task_id": "..."}
   → Poll until medias[].resource_status == 1
   → Extract url from completed media

Image Upload (Required Before Image Tasks)

The IMA Open API does NOT accept raw bytes or base64 images. All image inputs must be public HTTPS URLs.

When a user provides an image (local file, bytes, base64), you must upload it first and get a URL. This is exactly what the IMA frontend does before every image task.

Real Upload Flow (from IMA Frontend Source)

The frontend uses a two-step presigned URL flow via the IM platform:

Step 1: GET /api/rest/oss/getuploadtoken   → returns { ful, fdl }
          ful = presigned PUT URL (upload destination, expires ~7 days)
          fdl = final CDN download URL (use this as input_images value)

Step 2: PUT {ful}  with raw image bytes + Content-Type header
          → image is stored in Aliyun OSS: zhubite-imagent-bot.oss-us-east-1.aliyuncs.com
          → accessible via CDN: https://ima-ga.esxscloud.com/...

Step 1: Get Upload Token

GET https://imapi.liveme.com/api/rest/oss/getuploadtoken

  "ful_expire": "...",
  "fdl_expire": "...",
  "fdl_key": "..."
}

Step 2: Upload Image via Presigned URL

PUT {ful}
Content-Type: image/jpeg
Body: [raw image bytes]

No auth headers needed — the presigned URL already encodes the credentials.

Step 3: Use

fdl

as the Image URL

After the PUT succeeds, use

2. Use

   model_id

   and

   id

   (=

   model_version

   ) from the leaf
3. Pick

   credit_rules[].attribute_id

   matching your desired quality/size (

   attributes

   field shows the config)
4. Use

   form_config[].value

   as default

   parameters

   values

credit_rules[].attribute_id

→ required for task creation as

attribute_id

.

credit_rules[].points

→ required for task creation as

credit

and

cast.points

Polling stop condition (must implement exactly):

• Treat

  resource_status: null

  (or missing) as 0 (processing). Do not stop when you see null; backend may serialize Go

  *int

  as null.
• Stop only when ALL

  medias[].resource_status == 1

  and no

  status == "failed"

  . If you return on the first media with

  resource_status == 1

  while others are still 0, the task is not fully done and you will keep polling or get inconsistent state.
• Stop immediately if any

  status == "failed"

  or

  resource_status == 2

  or

  resource_status == 3

  .

⚠️

size

must be from

form_config

options (e.g.

"2k"

,

"4k"

,

"2048x2048"

).

"adaptive"

is NOT valid for SeeDream 4.5 i2i — causes error 400. Top-level

src_img_url

and

parameters.input_images

must both contain the input image URL. Some i2i models (e.g.

doubao-seededit-3.0-i2i

) may not be available in test environments — fall back to SeeDream 4.5.

image_to_video / first_last_frame_to_video / reference_image_to_video

{
  "src_img_url": ["https://first-frame.jpg", "https://last-frame.jpg"]
}

Index 0 = first frame (or reference), index 1 = last frame (first_last_frame only).
