+## 1.18.3 - 2026-01-23
+
+### Documentation
+- `baoyu-comic`: improves character reference handling with explicit Strategy A/B selection—Strategy A uses `--ref` parameter for skills that support it, Strategy B embeds character descriptions in prompts for skills that don't. Includes concrete code examples for both approaches.
+
+### Fixes
+- `baoyu-image-gen`: removes unsupported Gemini models (`gemini-2.0-flash-exp-image-generation`, `gemini-2.5-flash-preview-native-audio-dialog`) from multimodal model list.
+

+## 1.18.3 - 2026-01-23
+
+### 文档
+- `baoyu-comic`：改进角色参考处理流程，新增明确的 Strategy A/B 选择逻辑——Strategy A 使用 `--ref` 参数（适用于支持该参数的技能），Strategy B 将角色描述嵌入提示词（适用于不支持的技能）。包含两种方法的具体代码示例。
+
+### 修复
+- `baoyu-image-gen`：从多模态模型列表中移除不支持的 Gemini 模型（`gemini-2.0-flash-exp-image-generation`、`gemini-2.5-flash-preview-native-audio-dialog`）。

+**Before generating any page**:
+1. Read the image generation skill's SKILL.md
+2. Check if it supports reference image input (`--ref`, `--reference`, etc.)
+3. Choose the appropriate strategy below

+**Character Reference Strategy**:
+
+| Skill Capability | Strategy | Action |
+|------------------|----------|--------|
+| Supports `--ref` | **Strategy A** | Pass `characters/characters.png` with EVERY page |
+| Does NOT support `--ref` | **Strategy B** | Prepend character descriptions to EVERY prompt |

+**Strategy B: Embedding character descriptions in prompt**
+
+When skill does NOT support reference images, create combined prompt files:

+# prompts/01-page-xxx.md (with embedded character reference)
