advanced-file-management

advanced-file-management is a skill for Claude Code, Codex from MassLab-SII/open-agent-skills. It costs 26 tokens per session (1,553 once invoked), scanned A, original, Apache-2.0.

A set of tools for managing files and folders in batches. It can create folders, move files, list files recursively, and extract authors from HTML papers.

In plain words
What is it for?
Creating groups of folders, moving multiple files, listing everything under a directory, and collecting author names from HTML research papers.
Why use it?
Handling many files one at a time is tedious and makes repetitive organization work easier to get wrong.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python move_files.py ./backup ./data/log1.txt ./data/log2.txt ./temp/cache.dat.

Good fit Creating groups of folders, moving multiple files, listing everything under a directory, and collecting author names from HTML research papers.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

advanced-file-management scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 7 executable files (scripts/create_folders.py, scripts/extract_authors.py, scripts/list_all_files.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Advanced File Management Skill

This skill provides tools for desktop file management:

  1. Folder creation: Create multiple folders under a target directory
  2. Move files: Move multiple files to a target directory
  3. List all files: Recursively list all files under a directory
  4. Extract authors: Extract authors from HTML papers

Important Notes

  • Do not use other bash commands: Do not attempt to use general bash commands or shell operations like cat, ls.
  • Use relative paths: Use paths relative to the working directory (e.g., ./folder/file.txt or folder/file.txt).
  • Do not create scripts: Do not use write_file to create any scripts.

I. Skills

1. Create Multiple Folders

Creates multiple folders under a target directory.

Features

  • Creates multiple folders with specified names
  • Supports any number of folder names as arguments

Example

# Create 3 folders
python create_folders.py . folder1 folder2 folder3

# Create folders with specific names
python create_folders.py ./projects experiments learning personal

2. Move Multiple Files

Move multiple files to a target directory in a single operation.

Features

  • Move multiple files at once
  • Supports files from different directories
  • Reports success and failure for each file

Example

# Move 3 files to archive folder
python move_files.py ./archive file1.txt file2.txt file3.txt

# Move files from different directories
python move_files.py ./backup ./data/log1.txt ./data/log2.txt ./temp/cache.dat

3. List All Files

Recursively list all files under a given directory path. Useful for quickly understanding project directory structure.

Features

  • Recursively traverse all subdirectories
  • Option to exclude hidden files (like .DS_Store)
  • Output one file path per line, including both path and filename (relative to input directory)

Example

# List all files (excluding hidden)
python list_all_files.py .

# Include hidden files
python list_all_files.py ./data --include-hidden

Files

What ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
