Smart Folder Organizer

This skill provides a structured workflow for tidying up disorganized directories while ensuring data safety.

Core Mandates

1. Safety First: NEVER delete any file. Move files intended for deletion to specific subfolders within to_remove/ (e.g., to_remove/duplicates/ or to_remove/empty_folders/).
2. Strict Scoping: Operate ONLY within the current directory and its subdirectories. Never move or access files in the parent directory (..).
3. Preservation: If a file's category is ambiguous, move it to a Needs_Review/ folder rather than guessing incorrectly.
4. Large Files: For any file larger than 20MB, skip deep content analysis (such as reading PDF text) to prevent memory issues. Move these unanalyzed large files to a dedicated Needs_Review/LargeFiles/ directory.
5. Folder Handling: Recursively process all files within the current directory and its subdirectories. When moving files, place them in the categorized folders at the root level of the target directory (do not replicate the category structure inside every subfolder). Any empty subdirectories discovered or left behind must be moved to to_remove/empty_folders/.

Workflow

1. Smart Folder Detection

Before processing individual files, run scripts/detect_smart_folders.py <target_dir> to identify subdirectories that are already well-organized (e.g., git repositories, software projects, macOS app bundles).

• Action: Move each detected folder to Others/ as a whole — do NOT descend into or reorganize its contents.
• Logic: The script checks for project markers (.git/, package.json, Cargo.toml, Makefile, etc.) and app bundles (.app), returning a JSON list of matches with reasons.
• Skip: All subsequent steps should ignore the Others/ directory.

2. Duplicate Detection

Run the find_duplicates.py script to identify identical files.

• Action: Move identified duplicates to to_remove/duplicates/.
• Logic: Use file hashes (SHA256) via the scripts/find_duplicates.py script for deterministic results.

3. General Categorization

Organize files by extension and common patterns:

• Photos: Move to Photos/. (Screenshots to Photos/Screenshots/)
• Videos: Move to Videos/.
• Installers: Move to Installers/ (.dmg, .pkg, .exe, .msi).
• Archives: Move to Archives/ (.zip, .rar, etc.).

4. Deep PDF Analysis

For PDF files, read the first few pages to determine the document type and extract metadata for renaming.

• CRITICAL: Do NOT generate dynamic Python scripts to read PDFs. Instead, execute the scripts/extract_pdf_metadata.py script provided in this skill to extract text and analyze the document deterministically. The script uses pypdf with a sampling strategy (first 3 pages + last page) for fast and efficient classification.
• IMPORTANT: Use Universal Semantic Reasoning for document classification. Modern AI models can understand dozens of languages (English, Chinese, Spanish, etc.); prioritize the *intent* of the document (e.g., "requesting payment") over specific English keywords like "Invoice". Refer to references/classification.md for semantic guidelines.
• Multilingual Naming: For non-English documents, extract naming details (like [Vendor] or [Provider]) in their original script (e.g., Chinese characters). The standard date format yyyy-mm-dd remains unchanged.
• Invoices: Rename to yyyy-mm-dd-[Vendor]-[Inv#-][Amount].pdf and move to Documents/Invoices/.
• Bills: Rename to yyyy-mm-dd-[Provider]-[Service]-[Account#].pdf and move to Documents/Bills/.
• Receipts: Rename to yyyy-mm-dd-[Store]-[TotalAmount].pdf and move to Documents/Receipts/.
• Travel: Rename to yyyy-mm-dd-[Transport/Hotel]-[Confirmation#].pdf and move to Documents/Travel/.

5. Final Cleanup

• Group writing documents (.docx, .doc, .pages, .odt) into Documents/Writing/.
• Group spreadsheet files (.xlsx, .xls, .numbers, .ods, .csv) into Documents/Spreadsheets/.
• Group presentation files (.ppt, .pptx, .key, .odp) into Documents/Presentations/.
• Group audio files (.mp3, .wav, .flac, .m4a) into Audio/.
• Group remaining documents into Needs_Review/Documents/ by sub-type if applicable.
• If a PDF document was analyzed but the category is unknown, move it to Needs_Review/Unknown/.
• Move any other unhandled files to Needs_Review/.

Resources

scripts/find_duplicates.py

A Python script that deterministically finds identical files. It uses SHA-256 hashing to compare file contents rather than relying on filenames or sizes, returning a JSON list of duplicates.

scripts/extract_pdf_metadata.py

A Python helper script that extracts text from a PDF using the pypdf library. Use this instead of rolling your own script. It uses a sampling strategy (first 3 pages and the last page) to provide efficient text extraction for document classification, returning the text in a JSON wrapper.

scripts/detect_smart_folders.py

A Python script that scans immediate subdirectories of a target folder for project markers (.git/, package.json, Cargo.toml, Makefile, etc.) and app bundles (.app). Returns a JSON list of detected "smart" folders that should be moved to Others/ without being broken apart.

references/classification.md

Contains detailed keyword lists and naming conventions for PDFs and other document types.
