name: file-organizer description: Automatically organize, categorize, and clean up files. Use when user wants to (1) organize downloads or folders, (2) sort files by type/date/size, (3) find and remove duplicates, (4) bulk rename files, (5) clean up old/temp files, or (6) create folder structures for projects.

File Organizer

Automatically organize and manage file collections.

Core Functions

1. Sort by Type

Group files by extension:

/documents/    → .pdf, .doc, .docx, .txt
/images/       → .jpg, .png, .gif, .svg
/videos/       → .mp4, .mov, .avi
/archives/     → .zip, .rar, .7z
/audio/        → .mp3, .wav, .flac
/code/         → .js, .py, .html, .css

2. Sort by Date

Organize by modification time:

/2026/04/06/
/2026/03/

3. Find Duplicates

import hashlib

def find_duplicates(path):
    hashes = {}
    for file in Path(path).rglob('*'):
        if file.is_file():
            h = hashlib.md5(file.read_bytes()).hexdigest()
            hashes.setdefault(h, []).append(file)
    return {h: f for h, f in hashes.items() if len(f) > 1}

4. Bulk Rename

Patterns: - prefix_001.jpg, prefix_002.jpg - 2026-04-07_description.jpg - file_v1.txt, file_v2.txt

5. Cleanup Old Files

from datetime import datetime, timedelta

def cleanup_old(path, days=90):
    threshold = datetime.now() - timedelta(days=days)
    for file in Path(path).rglob('*'):
        if file.is_file() and datetime.fromtimestamp(file.stat().st_mtime) < threshold:
            file.unlink()  # or move to trash

Workflow

1. Scan - List all files in directory
2. Analyze - Get metadata (type, date, size, hash)
3. Plan - Show proposed organization
4. Execute - Move/copy/rename files
5. Report - Summary of changes

Safety Rules

• Always confirm before deleting or moving
• Use trash instead of permanent delete when possible
• Backup important files first
• Log all changes for undo capability
• Handle conflicts - ask about name collisions

这个技能功能比较全面，能帮你整理文件、找重复文件、批量重命名和清理垃圾文件。整体质量还不错，文档清晰易懂，安全考虑也比较周到。不过因为没有示例，实际用起来可能需要自己摸索。推荐一试。
