+## 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.

+
+## Script Directory
+
+**Important**: All scripts are located in the `scripts/` subdirectory of this skill.
+
+**Agent Execution Instructions**:
+1. Determine this SKILL.md file's directory path as `SKILL_DIR`
+2. Script path = `${SKILL_DIR}/scripts/<script-name>.ts`
+3. Replace all `${SKILL_DIR}` in this document with the actual path
+
+**Script Reference**:
+| Script | Purpose |
+|--------|---------|
+| `scripts/main.ts` | CLI entry point for image compression |
+
+## Quick Start
+
+```bash
+# Compress to WebP (default)
+npx -y bun ${SKILL_DIR}/scripts/main.ts image.png
+
+# Keep original format (PNG → PNG)
+npx -y bun ${SKILL_DIR}/scripts/main.ts image.png --format png
+
+# Custom quality
+npx -y bun ${SKILL_DIR}/scripts/main.ts image.png -q 75
+
+# Process directory
+npx -y bun ${SKILL_DIR}/scripts/main.ts ./images/ -r
+```
+
+## Commands
+
+### Single File Compression
+
+```bash
+# Basic (converts to WebP, replaces original)
+npx -y bun ${SKILL_DIR}/scripts/main.ts image.png
+
+# Custom output path
+npx -y bun ${SKILL_DIR}/scripts/main.ts image.png -o compressed.webp
+
+# Keep original file
+npx -y bun ${SKILL_DIR}/scripts/main.ts image.png --keep
+
+# Custom quality (0-100, default: 80)
+npx -y bun ${SKILL_DIR}/scripts/main.ts image.png -q 75
+
+# Keep original format
+npx -y bun ${SKILL_DIR}/scripts/main.ts image.png -f png
+```
+
+### Directory Processing
+
+```bash
+# Process all images in directory
+npx -y bun ${SKILL_DIR}/scripts/main.ts ./images/
+
+# Recursive processing
+npx -y bun ${SKILL_DIR}/scripts/main.ts ./images/ -r
+
+# With custom quality
+npx -y bun ${SKILL_DIR}/scripts/main.ts ./images/ -r -q 75
+```
+
+### Output Formats
+
+```bash
+# Plain text (default)
+npx -y bun ${SKILL_DIR}/scripts/main.ts image.png
+
+# JSON output
+npx -y bun ${SKILL_DIR}/scripts/main.ts image.png --json
+```
+
+## Options
+
+| Option | Short | Description | Default |
+|--------|-------|-------------|---------|
+| `<input>` | | Input file or directory | Required |
+| `--output <path>` | `-o` | Output path | Same path, new extension |
+| `--format <fmt>` | `-f` | webp, png, jpeg | webp |
+| `--quality <n>` | `-q` | Quality 0-100 | 80 |
+| `--keep` | `-k` | Keep original file | false |
+| `--recursive` | `-r` | Process directories recursively | false |
+| `--json` | | JSON output | false |
+| `--help` | `-h` | Show help | |
+
+## Compressor Selection
+
+Priority order (auto-detected):
+
+1. **sips** (macOS built-in, WebP support since macOS 11)
+2. **cwebp** (Google's official WebP tool)
+3. **ImageMagick** (`convert` command)
+4. **Sharp** (npm package, auto-installed by Bun)
+
+The skill automatically selects the best available compressor.
+
+## Output Format
+
+### Text Mode (default)
+
+```
+image.png → image.webp (245KB → 89KB, 64% reduction)
+```
+
+### JSON Mode
+
+```json
+{
+  "input": "image.png",
+  "output": "image.webp",
+  "inputSize": 250880,
+  "outputSize": 91136,
+  "ratio": 0.36,
+  "compressor": "sips"
+}
+```
+
+### Directory JSON Mode
+
+```json
+{
+  "files": [...],
+  "summary": {
+    "totalFiles": 10,
+    "totalInputSize": 2508800,
+    "totalOutputSize": 911360,
+    "ratio": 0.36,
+    "compressor": "sips"
+  }
+}
+```
+
+## Examples
+
+### Compress single image
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts photo.png
+# photo.png → photo.webp (1.2MB → 340KB, 72% reduction)
+```
+
+### Compress with custom quality
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts photo.png -q 60
+# photo.png → photo.webp (1.2MB → 280KB, 77% reduction)
+```
+
+### Keep original format
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts screenshot.png -f png --keep
+# screenshot.png → screenshot-compressed.png (500KB → 380KB, 24% reduction)
+```
+
+### Process entire directory
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts ./screenshots/ -r
+# Processed 15 files: 12.5MB → 4.2MB (66% reduction)
+```
+
+### Get JSON for scripting
+
+```bash
+npx -y bun ${SKILL_DIR}/scripts/main.ts image.png --json | jq '.ratio'

+## Extension Support

+### Output Directory
 
-Save to `[source-name-no-ext]/cover-image/` subdirectory in the same folder as the article:
+Each session creates an independent directory named by content slug:
 
 ```
-path/to/

-└── article/
-    └── cover-image/
 ├── prompts/
 │   └── cover.md

-Example: `/posts/ai-future.md` → `/posts/ai-future/cover-image/`
+**Slug Generation**:
+1. Extract main topic from content (2-4 words, kebab-case)
+2. Example: "The Future of AI" → `future-of-ai`
 
-### Without Article Path (Pasted Content)
+### Conflict Resolution
 
-Save to `./cover-image/[topic-slug]/`:
+If `cover-image/{topic-slug}/` already exists:
+- Append timestamp: `{topic-slug}-YYYYMMDD-HHMMSS`
+- Example: `ai-future` exists → `ai-future-20260118-143052`

-    └── cover.png
-```
 
-### Directory Backup
+Copy all sources with naming `source-{slug}.{ext}`:
+- `source-article.md` (main text content)
+- `source-logo.png` (image from conversation)
 
-If target directory exists, rename existing to `<dirname>-backup-YYYYMMDD-HHMMSS`
