+## 1.2.0 - 2026-01-18
+
+### Features
+- Session-independent output directories: each generation session creates a new directory (`<skill-suffix>/<topic-slug>/`), even for the same source file. Conflicts resolved by appending timestamp.
+- Multi-source file support: source files now saved as `source-{slug}.{ext}`, supporting multiple inputs (text, images, files from conversation).
+
+### Documentation
+- `CLAUDE.md`: updates Output Path Convention with new session-independent directory structure and multi-source file naming.
+- Multiple skills: updates file management sections to reflect new directory and source file conventions.
+  - `baoyu-slide-deck`, `baoyu-article-illustrator`, `baoyu-cover-image`, `baoyu-xhs-images`, `baoyu-comic`

+## 1.2.0 - 2026-01-18
+
+### 新功能
+- Session 独立输出目录：每次生成创建独立目录（`<skill-suffix>/<topic-slug>/`），即使是同一源文件也会新建目录。目录冲突时追加时间戳。
+- 多源文件支持：源文件现以 `source-{slug}.{ext}` 命名，支持多个输入（文本、图片、会话中的文件）。
+
+### 文档
+- `CLAUDE.md`：更新 Output Path Convention，采用新的 session 独立目录结构和多源文件命名规范。
+- 多个技能：更新文件管理部分，反映新的目录和源文件规范。
+  - `baoyu-slide-deck`、`baoyu-article-illustrator`、`baoyu-cover-image`、`baoyu-xhs-images`、`baoyu-comic`

 ### Output Path Convention
 
-Generated images from the same skill and source file MUST be grouped together:
+Each session creates an independent directory. Even the same source file generates a new directory per session.
 
-**With source file** (e.g., `/path/to/project/content/my-article.md`):
+**Output Directory**:
 ```
-/path/to/project/content/my-article/<skill-suffix>/
+<skill-suffix>/<topic-slug>/
 ```
-- Remove file extension from source filename
-- Use skill name suffix (e.g., `xhs-images`, `cover-image`, `slide-deck`)
-- Example: source `/tests-data/anthropic-economic-index.md` + skill `baoyu-xhs-images` → `/tests-data/anthropic-economic-index/xhs-images/`
+- `<skill-suffix>`: Skill name suffix (e.g., `xhs-images`, `cover-image`, `slide-deck`, `comic`)
+- `<topic-slug>`: Generated from content topic (2-4 words, kebab-case)
+- Example: `xhs-images/ai-future-trends/`
 
-**Without source file**:
-```
-./<skill-suffix>/<source-slug>/
-```
-- Place under current project directory
-- Use descriptive slug for the content
+**Slug Generation**:
+1. Extract main topic from content (2-4 words, kebab-case)
+2. Example: "Introduction to Machine Learning" → `intro-machine-learning`
 
-**Directory Backup**:
-- If output directory already exists, rename existing directory with timestamp
-- Format: `<dirname>-backup-YYYYMMDD-HHMMSS`
-- Example: `xhs-images` → `xhs-images-backup-20260117-143052`
+**Conflict Resolution**:
+If `<skill-suffix>/<topic-slug>/` already exists:
+- Append timestamp: `<topic-slug>-YYYYMMDD-HHMMSS`
+- Example: `ai-future` exists → `ai-future-20260118-143052`
+
+**Source Files**:
+- Copy all sources to `<skill-suffix>/<topic-slug>/` with naming: `source-{slug}.{ext}`
+- Multiple sources supported: text, images, files from conversation
+- Examples:
+  - `source-article.md` (main text content)
+  - `source-reference.png` (image from conversation)
+  - `source-data.csv` (additional file)
+- Original source files remain unchanged
