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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00026 | $0.01553 |
| Opus 5 | $0.00013 | $0.00776 |
| Sonnet 5 | $0.00005 | $0.00311 |
| Haiku 4.5 | $0.00003 | $0.00155 |
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.
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.

The opening of the file, as written. The whole thing — 284 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Advanced File Management Skill
This skill provides tools for desktop file management:
- Folder creation: Create multiple folders under a target directory
- Move files: Move multiple files to a target directory
- List all files: Recursively list all files under a directory
- 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.txtorfolder/file.txt). - Do not create scripts: Do not use
write_fileto 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
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.
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.

advanced-file-management is a skill published in the GitHub repository MassLab-SII/open-agent-skills (133 stars, last pushed 8mo ago), licensed Apache-2.0. It adds 26 tokens to every session and 1,553 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
