Overview
This skill enables efficient bulk processing of documents - convert, transform, extract, or analyze hundreds of files with parallel execution and progress tracking.
How to Use
- Describe what you want to accomplish
- Provide any required input data or files
- I'll execute the appropriate operations
Example prompts:
- "Convert 100 PDFs to Word documents"
- "Extract text from all images in a folder"
- "Batch rename and organize files"
- "Mass update document headers/footers"

Python Implementation
from concurrent.futures import ProcessPoolExecutor, as_completed
from pathlib import Path
from tqdm import tqdm
def process_file(file_path: Path) -> dict:
"""Process a single file."""
# Your processing logic here
return {"path": str(file_path), "status": "success"}
def batch_process(input_dir: str, pattern: str = "*.*", max_workers: int = 4):
"""Process all matching files in directory."""
files = list(Path(input_dir).glob(pattern))
results = []
with ProcessPoolExecutor(max_workers=max_workers) as executor:
futures = {executor.submit(process_file, f): f for f in files}
for future in tqdm(as_completed(futures), total=len(files)):
file = futures[future]
try:
result = future.result()
results.append(result)
except Exception as e:
results.append({"path": str(file), "error": str(e)})
return results
# Usage
results = batch_process("/documents/invoices", "*.pdf", max_workers=8)
print(f"Processed {len(results)} files")
Error Handling & Resume
import json
from pathlib import Path
class BatchProcessor:
def __init__(self, checkpoint_file: str = "checkpoint.json"):
self.checkpoint_file = checkpoint_file
self.processed = self._load_checkpoint()
def _load_checkpoint(self):
if Path(self.checkpoint_file).exists():
return json.load(open(self.checkpoint_file))
return {}
def _save_checkpoint(self):
json.dump(self.processed, open(self.checkpoint_file, "w"))
def process(self, files: list, processor_func):
for file in files:
if str(file) in self.processed:
continue # Skip already processed
try:
result = processor_func(file)
self.processed[str(file)] = {"status": "success", **result}
except Exception as e:
self.processed[str(file)] = {"status": "error", "error": str(e)}
self._save_checkpoint() # Resume-safe
Best Practices
- Use progress bars (tqdm) for user feedback
- Implement checkpointing for long jobs
- Set reasonable worker counts (CPU cores)
- Log failures for later review

Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
Use this skill whenever the user wants to do anything with PDF files. This includes reading or extracting text/tables from PDFs, combining or merging multiple PDFs into one, splitting PDFs apart, rotating pages, adding watermarks, creating new PDFs, filling PDF forms, encrypting/decrypting PDFs, extracting images, and OCR on scanned PDFs to make them searchable. If the user mentions a .pdf file or asks to produce one, use this skill.
Use this skill whenever the user wants to create, read, edit, or manipulate Word documents (.docx files). Triggers include: any mention of 'Word doc', 'word document', '.docx', or requests to produce professional documents with formatting like tables of contents, headings, page numbers, or letterheads. Also use when extracting or reorganizing content from .docx files, inserting or replacing images in documents, performing find-and-replace in Word files, working with tracked changes or comments, or converting content into a polished Word document. If the user asks for a 'report', 'memo', 'letter', 'template', or similar deliverable as a Word or .docx file, use this skill. Do NOT use for PDFs, spreadsheets, Google Docs, or general coding tasks unrelated to document generation.
Use this skill any time a .pptx file is involved in any way — as input, output, or both. This includes: creating slide decks, pitch decks, or presentations; reading, parsing, or extracting text from any .pptx file (even if the extracted content will be used elsewhere, like in an email or summary); editing, modifying, or updating existing presentations; combining or splitting slide files; working with templates, layouts, speaker notes, or comments. Trigger whenever the user mentions \"deck,\" \"slides,\" \"presentation,\" or references a .pptx filename, regardless of what they plan to do with the content afterward. If a .pptx file needs to be opened, created, or touched, use this skill.
Create and edit Obsidian Flavored Markdown with wikilinks, embeds, callouts, properties, and other Obsidian-specific syntax. Use when working with .md files in Obsidian, or when the user mentions wikilinks, callouts, frontmatter, tags, embeds, or Obsidian notes.
How to use it
Take claude-office-skills/batch-processor from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
