Organize files into subject folders using keyword-based classification of titles and abstracts, with fallback to full text extraction.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# File Organizer by Subject Skill
## Overview
Classify and move files (PDF, PPTX, DOCX) into subject folders using keyword matching on metadata and text content.
## Folder Setup
```python
import os, shutil
def create_subject_folders(base_dir, subjects):
for subject in subjects:
os.makedirs(os.path.join(base_dir, subject), exist_ok=True)
SUBJECTS = ['LLM', 'trapped_ion_and_qc', 'black_hole', 'DNA', 'music_history']
```
## Keyword-Based Classifier
```python
KEYWORDS = {
'LLM': [
'language model', 'large language', 'llm', 'gpt', 'bert', 'transformer',
'attention mechanism', 'natural language', 'nlp', 'text generation',
'chatgpt', 'instruction tuning', 'rlhf', 'tokenization', 'embedding',
'fine-tuning', 'prompt', 'in-context learning', 'chain of thought'
],
'trapped_ion_and_qc': [
'trapped ion', 'ion trap', 'quantum computing', 'qubit', 'quantum gate',
'quantum circuit', 'quantum error', 'decoherence', 'quantum entanglement',
'quantum supremacy', 'quantum advantage', 'quantum processor',
'laser cooling', 'penning trap', 'paul trap', 'quantum memory',

How to install
mdr add cxcscmu/skilllearnbench/file-organizer-by-subject@sha256:969c390447f58434The line at the top of this page pins the label git:20260424.d50cf5a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
