# IMA AI Creation

## ⚠️ 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` is WRONG; ✅ `gemini-3-pro-image` is CORRECT).

**Quick Reference Table:**

### 图像模型 (Image Models)

| 友好名称 (Friendly Name) | model_id | 说明 (Notes) |
|-------------------------|----------|-------------|
| Nano Banana2 | `gemini-3.1-flash-image` | ❌ NOT nano-banana-2, 预算选择 4-13 pts |
| Nano Banana Pro | `gemini-3-pro-image` | ❌ NOT nano-banana-pro, 高质量 10-18 pts |
| SeeDream 4.5 | `doubao-seedream-4.5` | ✅ Recommended default, 5 pts |
| Midjourney | `midjourney` | ✅ Same as friendly name, 8-10 pts |

### 视频模型 (Video Models)

| 友好名称 (Friendly Name) | model_id (t2v) | model_id (i2v) | 说明 (Notes) |
|-------------------------|---------------|----------------|-------------|
| Wan 2.6 | `wan2.6-t2v` | `wan2.6-i2v` | ⚠️ Note -t2v/-i2v suffix |
| IMA Video Pro (Sevio 1.0) | `ima-pro` | `ima-pro` | ✅ IMA native quality model |
| IMA Video Pro Fast (Sevio 1.0-Fast) | `ima-pro-fast` | `ima-pro-fast` | ✅ IMA native low-latency model |
| Kling O1 | `kling-video-o1` | `kling-video-o1` | ⚠️ Note video- prefix |
| Kling 2.6 | `kling-v2-6` | `kling-v2-6` | ⚠️ Note v prefix |
| Hailuo 2.3 | `MiniMax-Hailuo-2.3` | `MiniMax-Hailuo-2.3` | ⚠️ Note MiniMax- prefix |
| Hailuo 2.0 | `MiniMax-Hailuo-02` | `MiniMax-Hailuo-02` | ⚠️ Note 02 not 2.0 |
| Google Veo 3.1 | `veo-3.1-generate-preview` | `veo-3.1-generate-preview` | ⚠️ Note -generate-preview suffix |
| Sora 2 Pro | `sora-2-pro` | `sora-2-pro` | ✅ Straightforward |
| Pixverse | `pixverse` | `pixverse` | ✅ Same as friendly name |

### 音乐模型 (Music Models)

| 友好名称 (Friendly Name) | model_id | 说明 (Notes) |
|-------------------------|----------|-------------|
| Suno (sonic v4) | `sonic` | ⚠️ Simplified to sonic |
| DouBao BGM | `GenBGM` | ❌ NOT doubao-bgm |
| DouBao Song | `GenSong` | ❌ NOT doubao-song |

### 语音模型 (Speech/TTS Models)

| 友好名称 (Friendly Name) | model_id | 说明 (Notes) |
|-------------------------|----------|-------------|
| seed-tts-2.0 | `seed-tts-2.0` | ✅ Same as friendly name (default) |

**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:**
```bash
# ❌ 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` is installed, the agent may read its references for workflow decomposition and consistency guidance.

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:**
```python
# 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)

| User intent / keywords | Media type | task_type examples |
|------------------------|------------|---------------------|
| 画 / 生成图 / 图片 / image / 画一张 / 图生图 | **image** | `text_to_image`, `image_to_image` |
| 视频 / 生成视频 / video / 图生视频 / 文生视频 | **video** | `text_to_video`, `image_to_video`, `first_last_frame_to_video`, `reference_image_to_video` |
| 音乐 / 歌 / BGM / 背景音乐 / music / 作曲 | **music** | `text_to_music` |
| 语音 / 朗读 / TTS / 语音合成 / 配音 / speech / read aloud / text-to-speech | **speech** | `text_to_speech` |

If the request mixes media (e.g. "宣传片+配乐"), treat as **multi-media workflow**: read `workflow-design.md`, then plan image → video → music steps and use the correct task_type for each step.

### 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`) to call the IMA Open API. The script:
- 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

| Domain | Owner | Purpose | Data Sent | Privacy |
|--------|-------|---------|-----------|---------|
| `api.imastudio.com` | IMA Studio | Main API (product list, task creation, task polling) | Prompts, model IDs, generation params, **your API key** | Standard HTTPS, data processed for AI generation |
| `imapi.liveme.com` | IMA Studio | Image/Video upload service (presigned URL generation) | **Your API key**, file metadata (MIME type, extension) | Standard HTTPS, used for image/video tasks only |
| `*.aliyuncs.com`, `*.esxscloud.com` | Alibaba Cloud (OSS) | Image/video storage (file upload, CDN delivery) | Raw image/video bytes (via presigned URL, **NO API key**) | IMA-managed OSS buckets, presigned URLs expire after 7 days |

**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:

```bash

## Overview

Call IMA Open API to create AI-generated content. All endpoints require an `ima_*` API key. The core flow is: **query products → create task → poll until done**.

---

## 🔒 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` (resets to defaults)
- ✅ **Delete logs**: `rm -rf ~/.openclaw/logs/ima_skills/` (auto-cleanup after 7 days anyway)

### ⚠️ 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:**

| Data Type | Sent to IMA? | Stored Locally? | User Control |
|-----------|-------------|-----------------|--------------|
| Prompts (image/video/music) | ✅ Yes (required for generation) | ❌ No | None (required) |
| API key | ✅ Yes (authentication header) | ❌ No | Set via env var |
| user_id (optional CLI arg) | ❌ **Never** (local preference key only) | ✅ Yes (as prefs file key) | Change `--user-id` value |
| Model preferences | ❌ No | ✅ Yes (~/.openclaw) | Delete anytime |
| Generation logs | ❌ No | ✅ Yes (~/.openclaw) | Auto-cleanup 7 days |

**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

**Get your IMA API key:** Visit https://imastudio.com to register and get started.

### 🔧 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):**
```bash
# 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:

```json
{
  "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)
```python
knowledge_recommended_model = read_ima_knowledge_ai()  # e.g., "SeeDream 4.5"
```

**Step 2: Check user preference**
```python
user_pref = load_prefs().get(f"user_{user_id}", {}).get(task_type)  # e.g., {"model_id": "midjourney", ...}
```

**Step 3: Decide which model to use**
```python
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)**
```python
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:**

| User says | Action |
|-----------|--------|
| `用XXX` / `换成XXX` / `改用XXX` | Switch to model XXX + save as preference |
| `以后都用XXX` / `默认用XXX` / `always use XXX` | Save + confirm: `✅ 已记住！以后图片生成默认用 [XXX]` |
| `我喜欢XXX` / `我更喜欢XXX` | Save as preference |

**❌ 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:**

| User says | Action |
|-----------|--------|
| `用最好的` / `用最合适的` / `best` / `recommended` | Clear pref + use knowledge-ai recommendation |
| `推荐一个` / `你选一个` / `自动选择` | Clear pref + use knowledge-ai recommendation |
| `用默认的` / `用新的` | Clear pref + use knowledge-ai recommendation |
| `试试别的` / `换个试试` (without specific model) | Clear pref + use knowledge-ai recommendation |
| `重新推荐` | Clear pref + use knowledge-ai recommendation |

**Implementation:**
```python
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…

### 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
```

**🌟 Parameter Support Notes (All Task Types):**

### Image Models (text_to_image / image_to_image)

**🆕 MAJOR UPDATE: Nano Banana series now has NATIVE aspect_ratio support!**
- **Nano Banana Pro**: ✅ Supports `aspect_ratio` (1:1, 16:9, 9:16, 4:3, 3:4) NATIVELY
- **Nano Banana2**: ✅ Supports `aspect_ratio` (1:1, 16:9, 9:16, 4:3, 3:4) NATIVELY
- **SeeDream 4.5**: ✅ Supports 8 ratios via virtual params (1:1, 16:9, 9:16, 4:3, 3:4, 2:3, 3:2, 21:9)
- **Midjourney**: ❌ 1:1 only (fixed 1024x1024)

**aspect_ratio support details:**
- ✅ **aspect_ratio**: 
  - **SeeDream 4.5**: ✅ Supports 8 ratios via virtual params (1:1, 16:9, 9:16, 4:3, 3:4, 2:3, 3:2, 21:9)
  - **Nano Banana2**: ✅ **Native support** for 5 ratios (1:1, 16:9, 9:16, 4:3, 3:4)
  - **Nano Banana Pro**: ✅ **Native support** for 5 ratios (1:1, 16:9, 9:16, 4:3, 3:4)
  - **Midjourney**: ❌ 1:1 only (fixed 1024x1024)
- ✅ **size**: 
  - **Nano Banana2**: 512px, 1K, 2K, 4K (via different `attribute_id`s, 4-13 pts)
  - **Nano Banana Pro**: 1K, 2K, 4K (via different `attribute_id`s, 10-18 pts)
  - **SeeDream 4.5**: Adaptive default (5 pts)
  - **Midjourney**: 480p/720p (via `attribute_id`, 8/10 pts)

- ❌ **Non-standard aspect ratios** (7:3, 8:5, etc.): Not supported. Use closest supported ratio or video models.
- ✅ **n**: Multiple outputs supported (1-4), credit × n

**When user requests unsupported combinations for images:**
- **Midjourney + aspect_ratio (16:9, etc.)**: Recommend **SeeDream 4.5** or **Nano Banana series** instead
  ```
  ❌ Midjourney 暂不支持自定义 aspect_ratio（仅支持 1024x1024 方形）
  
  ✅ 推荐方案：
    1. SeeDream 4.5（支持虚拟参数 aspect_ratio）
       • 支持比例：1:1, 16:9, 9:16, 4:3, 3:4, 2:3, 3:2, 21:9
       • 成本：5 积分（性价比最佳）
    2. Nano Banana Pro/2（原生支持 aspect_ratio）
       • 支持比例：1:1, 16:9, 9:16, 4:3, 3:4
       • 成本：4-18 积分（按尺寸）
  
  需要我帮你用 SeeDream 4.5 生成吗？
  ```
- **Any model + 8K**: Inform user no model supports 8K, max is 4K (Nano Banana Pro)
- **Any model + non-standard ratio (7:3, 8:5, etc.)**: Non-standard ratio, not supported. Suggest closest supported ratio (e.g., 21:9 for ultra-wide, 2:3 for portrait)

### Video Models (text_to_video / image_to_video / first_last_frame / reference_image)
- ✅ **resolution**: 540P, 720P, 1080P, 2K, 4K (model-dependent, higher res = higher cost)
- ✅ **aspect_ratio**: 16:9, 9:16, 1:1, 4:3 (model-dependent, check `form_config`)
- ✅ **duration**: 4s, 5s, 10s, 15s (model-dependent, longer = higher cost)
- ⚠️ **generate_audio**: Supported by Veo 3.1, Kling O1, Hailuo (check `form_config`)
- ✅ **prompt_extend**: AI-powered prompt enhancement (most models support)
- ✅ **negative_prompt**: Content exclusion (most models support)
- ✅ **shot_type**: Single/multi-shot control (model-dependent)
- ✅ **seed**: Reproducibility control (most models support, -1 = random)
- ✅ **n**: Multiple outputs (1-4), credit × n

#### 🆕 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 ✅

### Music Models (text_to_music)

**Suno sonic-v5 (Full-Featured):**
- ✅ **custom_mode**: Suno only (enables vocal_gender, lyrics, tags support)
- ✅ **vocal_gender**: Suno only (male/female/mixed, requires custom_mode=True)
- ✅ **lyrics**: Suno only (custom lyrics support, requires custom_mode=True)
- ✅ **make_instrumental**: Suno only (force instrumental, no vocals)
- ✅ **auto_lyrics**: Suno only (AI-generated lyrics)
- ✅ **tags**: Suno only (genre/style tags)
- ✅ **negative_tags**: Suno only (exclude unwanted styles)
- ✅ **title**: Suno only (song title)
- ❌ **duration**: Fixed-length output (DouBao ~30s, Suno ~2min, not user-controllable)
- ✅ **n**: Multiple outputs supported (1-2), credit × n

**DouBao BGM/Song (Simplified):**
- ✅ **prompt**: Text description only
- ❌ **No advanced parameters** (no custom_mode, lyrics, vocal control)
- ❌ **duration**: Fixed ~30s output

**🎵 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`

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

**Step 2: Check user preference**
```python
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**
```python
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)**
```python
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:**

| User says | Action |
|-----------|--------|
| `用XXX` / `换成XXX` / `改用XXX` | Switch to model XXX + save as preference |
| `以后都用XXX` / `默认用XXX` / `always use XXX` | Save + confirm: `✅ 已记住！以后视频生成默认用 [XXX]` |
| `我喜欢XXX` / `我更喜欢XXX` | Save as preference |

**❌ 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:**

| User says | Action |
|-----------|--------|
| `用最好的` / `用最合适的` / `best` / `recommended` | Clear pref + use knowledge-ai recommendation |
| `推荐一个` / `你选一个` / `自动选择` | Clear pref + use knowledge-ai recommendation |
| `用默认的` / `用新的` | Clear pref + use knowledge-ai recommendation |
| `试试别的` / `换个试试` (without specific model) | Clear pref + use knowledge-ai recommendation |
| `重新推荐` | Clear pref + use knowledge-ai recommendation |

**Implementation:**
```python
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)

| Task Type | Model | Estimated Time | Poll Every | Send Progress Every |
|-----------|-------|---------------|------------|---------------------|
| **text_to_image** | SeeDream 4.5 | 25~60s | 5s | 20s |
| | Nano Banana2 💚 | 20~40s | 5s | 15s |
| | Nano Banana Pro | 60~120s | 5s | 30s |
| | Midjourney 🎨 | 40~90s | 8s | 25s |
| **image_to_image** | SeeDream 4.5 | 25~60s | 5s | 20s |
| | Nano Banana2 💚 | 20~40s | 5s | 15s |
| | Nano Banana Pro | 60~120s | 5s | 30s |
| | Midjourney 🎨 | 40~90s | 8s | 25s |
| **text_to_video** | Wan 2.6, Hailuo 2.0/2.3, Vidu Q2, Pixverse | 60~120s | 8s | 30s |
| | SeeDance 1.5 Pro, Kling 2.6, Veo 3.1 | 90~180s | 8s | 40s |
| | Kling O1, Sora 2 Pro | 180~360s | 8s | 60s |
| **image_to_video** | Same ranges as text_to_video | — | 8s | 40s |
| **first_last_frame / reference** | Kling O1, Veo 3.1 | 180~360s | 8s | 60s |
| **text_to_music** | DouBao BGM / Song | 10~25s | 5s | 10s |
| | Suno (sonic-v5) | 20~45s | 5s | 15s |
| **text_to_speech** | (varies by model) | 5~30s | 3s | 10s |

`estimated_max_seconds` = upper bound of the range (e.g. 60 for SeeDream 4.5, 40 for Nano Banana2, 120 for Nano Banana Pro, 90 for Midjourney, 180 for Kling 2.6, 360 for Kling O1).

---

### 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` tool). This reply will automatically appear FIRST in the conversation.

**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` tool to push a notification immediately:

```
[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]` seconds per the table.  
Send a progress update every `[Send Progress Every]` seconds.

```
⏳ 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):
```python
# 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):
```python
# 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)

```python
# 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]%`，已等待 [elapsed]s，预计最长 [max]s. Cap progress at 95% until API returns success.

**Step 3 — Success (message tool)**  
When `resource_status == 1` and `status != "failed"`, send **media** = `medias[0].url` and **caption**:
```
✅ 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):**

| Technical | ✅ Say (CN) | ✅ Say (EN) |
|-----------|-------------|-------------|
| 401 Unauthorized | 密钥无效或未授权，请至 imaclaw.ai 生成新密钥 | API key invalid; generate at imaclaw.ai |
| 4008 Insufficient points | 积分不足，请至 imaclaw.ai 购买积分 | Insufficient points; buy at imaclaw.ai |
| Invalid product attribute | 参数配置异常，请稍后重试 | Configuration error, try again later |
| Error 6006 / 6010 | 积分或参数不匹配，请换模型或重试 | Points/params mismatch, try another model |
| resource_status == 2 / status failed | 语音合成失败，建议换模型或缩短文本 | Synthesis failed, try another model or shorter text |
| timeout | 合成超时，请稍后重试 | Timed out, try again later |
| Network error | 网络不稳定，请检查后重试 | Network unstable, check and retry |
| Text too long (TTS) | 文本过长，请缩短后重试 | Text too long, please shorten |

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` or any API/network error, send:

```
❌ [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).

| Technical Error | ❌ Never Say | ✅ Say Instead (Chinese) | ✅ Say Instead (English) |
|----------------|-------------|------------------------|------------------------|
| `401 Unauthorized` 🆕 | Invalid API key / 401 Unauthorized | ❌ API密钥无效或未授权<br>💡 **生成新密钥**: https://www.imaclaw.ai/imaclaw/apikey | ❌ API key is invalid or unauthorized<br>💡 **Generate API Key**: https://www.imaclaw.ai/imaclaw/apikey |
| `4008 Insufficient points` 🆕 | Insufficient points / Error 4008 | ❌ 积分不足，无法创建任务<br>💡 **购买积分**: https://www.imaclaw.ai/imaclaw/subscription | ❌ Insufficient points to create this task<br>💡 **Buy Credits**: https://www.imaclaw.ai/imaclaw/subscription |
| `"Invalid product attribute"` / `"Insufficient points"` | Invalid product attribute | 生成参数配置异常，请稍后重试 | Configuration error, please try again later |
| `Error 6006` (credit mismatch) | Error 6006 | 积分计算异常，系统正在修复 | Points calculation error, system is fixing |
| `Error 6009` (no matching rule) | Error 6009 | 参数组合不匹配，已自动调整 | Parameter mismatch, auto-adjusted |
| `Error 6010` (attribute_id mismatch) | Attribute ID does not match | 模型参数不匹配，请尝试其他模型 | Model parameters incompatible, try another model |
| `error 400` (bad request) | error 400 / Bad request | 请求参数有误，请稍后重试 | Invalid request parameters, please try again |
| `resource_status == 2` | Resource status 2 / Failed | 生成过程遇到问题，建议换个模型试试 | Generation failed, please try another model |
| `status == "failed"` (no details) | Task failed | 这次生成没成功，要不换个模型试试？ | Generation unsuccessful, try a different model? |
| `timeout` | Task timed out / Timeout error | 生成时间过长已超时，建议用更快的模型 | Generation took too long, try a faster model |
| Network error / Connection refused | Connection refused / Network error | 网络连接不稳定，请检查网络后重试 | Network connection unstable, check network and retry |
| Rate limit exceeded | 429 Too Many Requests / Rate limit | 请求过于频繁，请稍等片刻再试 | Too many requests, please wait a moment |
| Prompt moderation (Sora only) | Content policy violation | 提示词包含敏感内容，请修改后重试 | Prompt contains restricted content, please modify |
| Model unavailable | Model not available / 503 Service Unavailable | 当前模型暂时不可用，建议换个模型 | Model temporarily unavailable, try another model |
| **Lyrics format error (Suno only)** 🎵 | Invalid lyrics format | 歌词格式有误，请调整后重试 | Lyrics format error, adjust and retry |
| **Prompt too short/long (Music)** 🎵 | Prompt length invalid | 音乐描述过短或过长，请调整到合适长度 (建议20-100字) | Music description too short or long, adjust to appropriate length (20-100 chars recommended) |
| **Text too long (TTS)** 🔊 | TTS text length | 文本过长，请缩短后重试 | Text too long, please shorten and retry |

**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:**

| Task Type | Failed Model | First Alt | Second Alt |

| **text_to_speech** 🔊 | (any) | Query `--list-models` for alternatives | Use another model_id from product list |

**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.

- 💡 **Best value**: **SeeDream 4.5** at 5pts offers aspect ratio flexibility; **Nano Banana2** 512px at 4pts for fastest/cheapest


### Video Generation

#### IMA Sevio Family (Dynamic Routing)

| Name | model_id | Typical positioning | task_type support |
|------|----------|---------------------|-------------------|
| IMA Video Pro (Sevio 1.0) | `ima-pro` | Higher quality / consistency | `text_to_video`, `image_to_video`, `first_last_frame_to_video`, `reference_image_to_video` |
| IMA Video Pro Fast (Sevio 1.0-Fast) | `ima-pro-fast` | Lower latency / faster iteration | `text_to_video`, `image_to_video`, `first_last_frame_to_video`, `reference_image_to_video` |

Notes:
- `ima-all-ai` does not hardcode Sevio availability; it resolves by runtime `product/list`.
- If a Sevio model is temporarily absent for a category, use `--list-models` result as final source.

|----------|------|----------|------|-------|
| text_to_music | Suno | `sonic` | 25 pts | sonic-v5; custom_mode, lyrics, vocal_gender |
| text_to_music | DouBao BGM | `GenBGM` | 30 pts | Background music |
| text_to_music | DouBao Song | `GenSong` | 30 pts | Song generation |

### Speech (TTS) — text_to_speech

Models and credits are **not fixed**. Always call `GET /open/v1/product/list?category=text_to_speech` (or run the script with `--task-type text_to_speech --list-models`) to get current model_id, attribute_id, and credit.

**ima-all-ai has complete TTS capability:** This document and the bundled `ima_create.py` provide full TTS support (routing, parameters, create/poll, UX protocol Steps 0–5, error translation). The **ima-tts-ai** skill is an optional standalone package with the same specification.

#### TTS Task Detail — Response Shape

Poll `POST /open/v1/tasks/detail` until completion. For TTS, `medias[]` uses the same structure as other IMA audio tasks:

| Field | Type | Meaning |
|-------|------|--------|
| `resource_status` | int or null | 0=处理中, 1=可用, 2=失败, 3=已删除；null 视为 0 |
| `status` | string | "pending" / "processing" / "success" / "failed" |
| `url` | string | Audio URL when resource_status=1 (mp3/wav) |
| `duration_str` | string | Optional, e.g. "12s" |
| `format` | string | Optional, e.g. "mp3", "wav" |

**Success example:** When all medias have `resource_status == 1` and `status != "failed"`, read `medias[0].url` (or `watermark_url`). Example: `{"medias":[{"resource_status":1,"status":"success","url":"https://cdn.../output.mp3","duration_str":"12s","format":"mp3"}]}`.

#### TTS Create Task — Request Shape

`task_type`: `"text_to_speech"`. No image input: `src_img_url: []`, `input_images: []`. `prompt` (text to speak) must be inside `parameters[].parameters`, not at top level. Extra fields (e.g. voice_id, speed) come from product `form_config`; pass via `--extra-params` and only include params present in the product’s credit_rules/form_config.

#### TTS Common Mistakes

| Mistake | Fix |
|---------|-----|
| prompt at top level | Put prompt inside `parameters[].parameters` (script does this) |
| Wrong or missing attribute_id | Always call product list first; use credit_rules |
| Single poll | Poll until all medias have resource_status == 1 |
| Ignoring status when resource_status=1 | Check status != "failed" |
| Sending params not in form_config/credit_rules | Use only params from product list; script reflection strips others on retry |

> Always call `GET /open/v1/product/list?category=<type>` first to get the live `attribute_id` and `form_config` defaults required for task creation.

There are two equivalent route systems serving the same backend logic:

| Route | Auth | Use Case |
|-------|------|----------|
| `/open/v1/` | `Authorization: Bearer ima_*` only | Third-party / agent access |
| `/api/v3/` | Token + API Key (dual auth) | Frontend App |

**This skill documents the `/open/v1/` Open API.** All business logic (credit validation, N-flattening, risk control) runs identically on both paths.

## Environment

Base URL: `https://api.imastudio.com`

Required/recommended headers for all `/open/v1/` endpoints:

| Header | Required | Value | Notes |
|--------|----------|-------|-------|
| `Authorization` | ✅ | `Bearer ima_your_api_key_here` | API key authentication |
| `x-app-source` | ✅ | `ima_skills` | Fixed value — identifies skill-originated requests |
| `x_app_language` | recommended | `en` / `zh` | Product label language; defaults to `en` if omitted |

```
Authorization: Bearer ima_your_api_key_here
x-app-source: ima_skills

## 📤 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.**

| Task Type | Input Required? | Upload Before Create? | Notes |
|-----------|----------------|----------------------|-------|
| **text_to_image** | ❌ No | — | Prompt only |
| **image_to_image** | ✅ Yes (1 image) | ✅ Upload first | Single input image |
| **text_to_video** | ❌ No | — | Prompt only |
| **image_to_video** | ✅ Yes (1 image) | ✅ Upload first | Single input image |
| **first_last_frame_to_video** | ✅ Yes (2 images) | ✅ Upload first | First + last frame |
| **reference_image_to_video** | ✅ Yes (1+ images) | ✅ Upload first | Reference image(s) |
| **text_to_music** | ❌ No | — | Prompt only |
| **text_to_speech** | ❌ No | — | Prompt only (text to speak) |

**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):**
```python
# 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)

```python
# 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.**

| **All others** | any | — | → query `/open/v1/product/list` | — | Always runtime query |

⚠️ **Production warning**: `attribute_id` and `credit` values change frequently in production. Always call `/open/v1/product/list` at runtime; above table is pre-queried reference only (2026-02-27).

### Common Mistakes (and resulting errors)

| Mistake | Error |
|---------|-------|
| `attribute_id` is `0` or missing | `"Invalid product attribute"` + `"Insufficient points"` |
| `attribute_id` outdated (production changed) | Same errors; always query product list first |
| **`attribute_id` doesn't match parameter combination** | **Error 6010: "Attribute ID does not match the calculated rule"** |
| `prompt` at outer `parameters[]` level | Prompt ignored; wrong routing |
| `cast` missing from inner `parameters.parameters` | Billing validation failure |
| `credit` value wrong or missing | Error 6006 |
| `model_name` / `model_version` missing | Wrong backend routing |
| Skipped product list, used table values directly | All of the above |

**⚠️ Critical for Google Veo 3.1 and multi-rule models:**

Models like Google Veo 3.1 have **multiple `credit_rules`**, each with a different `attribute_id` for different parameter combinations:
- `720p + 4s + optimized` → attribute_id A
- `720p + 8s + optimized` → attribute_id B  
- `4K + 4s + high` → attribute_id C

The script automatically selects the correct `attribute_id` by matching your parameters (`duration`, `resolution`, `compression_quality`, `generate_audio`) against each rule's `attributes`. If the match fails, you get error 6010.

**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
```

Required query parameters (11 total — sourced directly from frontend `generateUploadInfo`):

| Parameter | Example | Description |
|-----------|---------|-------------|
| `appUid` | `ima_xxx...` | **Use IMA API key directly** — no separate login needed |
| `appId` | `webAgent` | App identifier (fixed) |
| `appKey` | `32jdskjdk320eew` | App secret (fixed, used for `sign` generation) |
| `cmimToken` | `ima_xxx...` | **Use IMA API key directly** — same as appUid |
| `sign` | `117CF6CF...` | IM auth HMAC: `SHA1("webAgent\|32jdskjdk320eew\|{timestamp}\|{nonce}").upper()` |
| `timestamp` | `1772042430` | Unix timestamp (seconds), generated per request |
| `nonce` | `CxI1FLI5ajLJZ1jlxZmeg` | Random nonce string, generated per request |
| `fService` | `privite` | Fixed: storage service type |
| `fType` | `picture` | `picture` for images, `video`, `audio` |
| `fSuffix` | `jpeg` | File extension: `jpeg`, `png`, `mp4`, `mp3` |
| `fContentType` | `image/jpeg` | MIME type of the file |

> **简化认证**：直接使用 IMA API key 填充 `appUid` 和 `cmimToken` 参数，无需单独获取凭证。

Response:
```json
{
  "ful": "https://zhubite-imagent-bot.oss-us-east-1.aliyuncs.com/webAgent/privite/2026/02/26/..._uuid.jpeg?Expires=...&OSSAccessKeyId=...&Signature=...",
  "fdl": "https://ima-ga.esxscloud.com/webAgent/privite/2026/02/26/..._uuid.jpeg",
  "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 `fdl` (the CDN URL) as the value for `input_images` / `src_img_url`.

### Python Implementation

## Quick Reference

### Task Types (category values)

| category | Capability | Input |
|----------|------------|-------|
| `text_to_image` | Text → Image | prompt |
| `image_to_image` | Image → Image | prompt + input_images |
| `text_to_video` | Text → Video | prompt |
| `image_to_video` | Image → Video | prompt + input_images |
| `first_last_frame_to_video` | First+Last Frame → Video | prompt + src_img_url[2] |
| `reference_image_to_video` | Reference Image → Video | prompt + src_img_url[1+] |
| `text_to_music` | Text → Music | prompt |
| `text_to_speech` | Text → Speech | prompt (text to speak) |

### Detail API status values

Each media in `medias[]` has two fields:

| Field | Type | Values | Description |
|-------|------|--------|-------------|
| **`resource_status`** | int (or `null`) | `0`, `1`, `2`, `3` | 0=处理中, 1=可用, 2=失败, 3=已删除。API 可能返回 `null`，需当作 0。 |
| **`status`** | string | `"pending"`, `"processing"`, `"success"`, `"failed"` | 任务状态文案。轮询时以 `resource_status` 为准；`status == "failed"` 表示失败。 |

Poll on `resource_status` first, then ensure `status` is not `"failed"`:

| `resource_status` | `status` | Meaning | Action |
|-------------------|----------|---------|--------|
| `0` or **`null`** | `pending` / `processing` | 处理中 | Keep polling; do not stop (null = 0) |
| `1` | `success` (or `completed`) | **完成** | Read `url`; stop only when **all** medias are 1 |
| `1` | `failed` | 失败 (status 优先) | Stop, handle error |
| `2` | any | 失败 | Stop, handle error |
| `3` | any | 已删除 | Stop |

> **Important**: (1) Treat `resource_status: null` as 0. (2) Stop only when **all** medias have `resource_status == 1`. (3) When `resource_status=1`, still check `status != "failed"`.

---

## API 1: Product List

```
GET /open/v1/product/list?app=ima&platform=web&category=text_to_image
```

Internally calls downstream `/v1/products/listv2`. Returns a **V2 tree structure**: `type=2` nodes are model groups, `type=3` nodes are versions (leaves). Only `type=3` nodes contain `credit_rules` and `form_config`.

> `webAgent` is auto-converted to `ima` by the gateway — you can use either value for `app`.

```json
[
  {
    "id": "SeeDream",
    "type": "2",
    "name": "SeeDream",
    "model_id": "",
    "children": [
      {
        "id": "doubao-seedream-4-0-250828",
        "type": "3",
        "name": "SeeDream 4.0",
        "model_id": "doubao-seedream-4.0",
        "credit_rules": [
          { "attribute_id": 332, "points": 5, "attributes": { "default": "enabled" } }
        ],
        "form_config": [
          { "field": "size", "type": "tags", "value": "1K",
            "options": [{"label":"1K","value":"1K"}, {"label":"2K","value":"2K"}] }
        ]
      }
    ]
  }
]
```

**How to pick a version for task creation:**
1. Traverse nodes to find `type=3` leaves (versions)
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`.

---

## API 2: Create Task

```
POST /open/v1/tasks/create
```

### Request Structure

```json
{
  "task_type": "text_to_image",
  "enable_multi_model": false,
  "src_img_url": [],
  "upload_img_src": "",
  "parameters": [
    {
      "attribute_id": 8538,
      "model_id":      "doubao-seedream-4.5",
      "model_name":    "SeeDream 4.5",
      "model_version": "doubao-seedream-4-5-251128",
      "app":           "ima",
      "platform":      "web",
      "category":      "text_to_image",
      "credit":        5,
      "parameters": {
        "prompt":       "a beautiful mountain sunset, photorealistic",
        "size":         "4k",
        "n":            1,
        "input_images": [],
        "cast":         {"points": 5, "attribute_id": 8538}
      }
    }
  ]
}
```

### Field Reference

| Field | Required | Description |
|-------|----------|-------------|
| `task_type` | ✅ | Must match `parameters[].category` |
| `parameters[].attribute_id` | ✅ | From `credit_rules[].attribute_id` in product list |
| `parameters[].model_id` | ✅ | From `type=3` leaf node `model_id` |
| `parameters[].model_version` | ✅ | From `type=3` leaf node `id` |
| `parameters[].app` | ✅ | Use `ima` (or `webAgent`, auto-converted) |
| `parameters[].platform` | ✅ | Use `web` |
| `parameters[].category` | ✅ | Must match top-level `task_type` |
| `parameters[].credit` | ✅ | Must equal `credit_rules[].points`. Error 6006 if wrong. |
| `parameters[].parameters.prompt` | ✅ | The actual prompt text used by downstream service |
| `parameters[].parameters.cast` | ✅ | `{"points": N, "attribute_id": N}` — mirrors credit |
| `parameters[].parameters.n` | ✅ | Number of outputs (usually `1`). Gateway flattens N>1 into separate resources. |
| `parameters[].parameters.input_images` | image tasks | Array of input image URLs |
| top-level `src_img_url` | multi-image | Array for first_last_frame / reference tasks |

### N-Field Flattening (Gateway Internal Logic)

When `n > 1`, the gateway automatically:
1. Generates `n` independent `resourceBizId` values
2. Deducts credits `n` times (one per resource)
3. Creates `n` separate tasks in the downstream service

Response `medias[]` will contain `n` items. Poll until **all** have `resource_status == 1`.

### Response

```json
{
  "code": 0,
  "data": {
    "id": "task_abc123",
    "biz_id": "biz_xxx",
    "task_type": "text_to_image",
    "medias": [],
    "generate_count": 1,
    "created_at": 1700000000000,
    "timeout_at": 1700000300000
  }
}
```

`data.id` = task ID for polling. `timeout_at` = Unix ms deadline.

---

## API 3: Task Detail (Poll)

```
POST /open/v1/tasks/detail
{"task_id": "<id from create response>"}
```

Poll every 2–5s (8s+ for video). Completed response:

```json
{
  "id": "task_abc",
  "medias": [{
    "resource_status": 1,
    "status": "success",
    "url": "https://cdn.../output.jpg",
    "cover": "https://cdn.../cover.jpg",
    "format": "jpg",
    "width": 1024,
    "height": 1024
  }]
}
```

**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`.

## Task Type Examples

### text_to_image ✅ Verified
No image input. `src_img_url: []`, `input_images: []`. See API 2 for full example.

### text_to_video ✅ Verified
Extra fields vs text_to_image — all from `form_config` defaults:

```json
{
  "task_type": "text_to_video",
  "src_img_url": [],
  "parameters": [{
    "attribute_id":  4838,
    "model_id":      "wan2.6-t2v",
    "model_name":    "Wan 2.6",
    "model_version": "wan2.6-t2v",
    "category":      "text_to_video",
    "credit":        3,
    "app": "ima", "platform": "web",
    "parameters": {
      "prompt":          "a puppy dancing happily, sunny meadow",
      "negative_prompt": "",
      "prompt_extend":   false,
      "duration":        5,
      "resolution":      "1080P",
      "aspect_ratio":    "16:9",
      "shot_type":       "single",
      "seed":            -1,
      "n":               1,
      "input_images":    [],
      "cast":            {"points": 3, "attribute_id": 4838}
    }
  }]
}
```
> Video-specific fields from `form_config`: `duration` (seconds), `resolution`, `aspect_ratio`, `shot_type`, `negative_prompt`, `prompt_extend`.
> Poll every 8s (video generation is slower). Response `medias[].cover` = first-frame thumbnail.

### text_to_music
No image input. `src_img_url: []`, `input_images: []`.

### image_to_image ✅ Verified
```json
{
  "task_type": "image_to_image",
  "src_img_url": ["https://...input.jpg"],
  "parameters": [{
    "attribute_id":  8560,
    "model_id":      "doubao-seedream-4.5",
    "model_version": "doubao-seedream-4-5-251128",
    "category":      "image_to_image",
    "credit":        5,
    "app": "ima", "platform": "web",
    "parameters": {
      "prompt":       "turn into oil painting style",
      "size":         "4k",
      "n":            1,
      "input_images": ["https://...input.jpg"],
      "cast":         {"points": 5, "attribute_id": 8560}
    }
  }]
}
```
> ⚠️ `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
```json
{
  "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).

## Common Mistakes

| Mistake | Fix |
|---------|-----|
| `attribute_id` not from `credit_rules` | Always fetch product list first |
| `credit` value wrong | Must exactly match `credit_rules[].points` — error 6006 |
| `prompt` at wrong location | Put prompt in `parameters[].parameters.prompt` (nested), not only at top level |
| Polling `biz_id` instead of `id` | Use `id` (task ID) for `/tasks/detail` |
| Single-poll instead of loop | Poll until `resource_status == 1` for ALL medias |
| Missing `app` / `platform` in parameters | Required fields — use `ima` / `web` |
| `category` mismatch | `parameters[].category` must match top-level `task_type` |
| `resource_status == 2` not handled | Check for failure, don't loop forever |
| `status == "failed"` ignored | `resource_status=1` + `status="failed"` means actual failure |
| `n > 1` and only checking first media | All `n` media items must reach `resource_status == 1` |
