Our review
A small command-line tool built only on the Python standard library that counts words and characters in text files, reports word frequencies, and applies case transformations, with JSON or human-readable output.
Strengths
- Zero external dependencies — Python 3.7+ standard library only
- Dual JSON/text output that pipes cleanly into other scripts
- Batch processing of a whole directory with progress reporting
- Doubles as a documented template for the expected BASIC-tier skill structure
Limitations
- Deliberately basic statistics: no stemming, language detection, or syntactic analysis
- Case transformations are naive — title mode does not handle Unicode or locale edge cases
- It is a demonstration implementation rather than production-hardened code, and the Architecture section of the document is cut off
Use it for a quick word/character count or case conversion on plain text files from the terminal, or as a starting template when writing a new skill.
Skip it when you need real NLP (tokenization, sentiment, multilingual handling) or streaming processing of very large corpora.
Security analysis
SafeThe skill only describes a Python text processor using standard library functions for analysis and transformation of local text files. It does not involve network access, shell execution, destructive commands, or data exfiltration. Batch processing operates on user-specified directories and outputs to user-specified locations, with no inherent risk beyond normal file I/O.
No concerns found
Examples
Analyze notes.txt with the sample text processor and give me the word count, unique words, and most frequent word as JSON.Convert every .txt file in drafts/ to title case with the text processor and write the transformed files into output/.Use the sample text processor as a reference to scaffold a new BASIC-tier skill with the same file layout, CLI conventions, and JSON/text dual output.description: Apply the sample-skill skill.
Sample Text Processor
Name: sample-text-processor Tier: BASIC Category: Text Processing Dependencies: None (Python Standard Library Only) Author: Claude Skills Engineering Team Version: 1.0.0 Last Updated: 2026-02-16
Description
The Sample Text Processor is a simple skill designed to demonstrate the basic structure and functionality expected in the claude-skills ecosystem. This skill provides fundamental text processing capabilities including word counting, character analysis, and basic text transformations.
This skill serves as a reference implementation for BASIC tier requirements and can be used as a template for creating new skills. It demonstrates proper file structure, documentation standards, and implementation patterns that align with ecosystem best practices.
The skill processes text files and provides statistics and transformations in both human-readable and JSON formats, showcasing the dual output requirement for skills in the claude-skills repository.
Features
Core Functionality
- Word Count Analysis: Count total words, unique words, and word frequency
- Character Statistics: Analyze character count, line count, and special characters
- Text Transformations: Convert text to uppercase, lowercase, or title case
- File Processing: Process single text files or batch process directories
- Dual Output Formats: Generate results in both JSON and human-readable formats
Technical Features
- Command-line interface with comprehensive argument parsing
- Error handling for common file and processing issues
- Progress reporting for batch operations
- Configurable output formatting and verbosity levels
- Cross-platform compatibility with standard library only dependencies
Usage
Basic Text Analysis
python text_processor.py analyze document.txt
python text_processor.py analyze document.txt --output results.json
Text Transformation
python text_processor.py transform document.txt --mode uppercase
python text_processor.py transform document.txt --mode title --output transformed.txt
Batch Processing
python text_processor.py batch text_files/ --output results/
python text_processor.py batch text_files/ --format json --output batch_results.json
Examples
Example 1: Basic Word Count
$ python text_processor.py analyze sample.txt
=== TEXT ANALYSIS RESULTS ===
File: sample.txt
Total words: 150
Unique words: 85
Total characters: 750
Lines: 12
Most frequent word: "the" (8 occurrences)
Example 2: JSON Output
$ python text_processor.py analyze sample.txt --format json
{
"file": "sample.txt",
"statistics": {
"total_words": 150,
"unique_words": 85,
"total_characters": 750,
"lines": 12,
"most_frequent": {
"word": "the",
"count": 8
}
}
}
Example 3: Text Transformation
$ python text_processor.py transform sample.txt --mode title
Original: "hello world from the text processor"
Transformed: "Hello World From The Text Processor"
Installation
This skill requires only Python 3.7 or later with the standard library. No external dependencies are required.
- Clone or download the skill directory
- Navigate to the scripts directory
- Run the text processor directly with Python
cd scripts/
python text_processor.py --help
Configuration
The text processor supports various configuration options through command-line arguments:
--format: Output format (json, text)--verbose: Enable verbose output and progress reporting--output: Specify output file or directory--encoding: Specify text file encoding (default: utf-8)
Architecture
The skill follows a simple modular architecture:
- TextProcessor Class: Core processing logic and statistics calculation
- OutputFormatter Class: Handles dual output format generation
- FileManager Class: Manages file I/O operations and batch processing
- CLI Interface: Command-line argument parsing and user interaction
Error Handling
The skill includes comprehensive error handling for:
- File not found or permission errors
- Invalid encoding or corrupted text files
- Memory limitations for very large files
- Output directory creation and write permissions
- Invalid command-line arguments and parameters
Performance Considerations
- Efficient memory usage for large text files through streaming
- Optimized word counting using dictionary lookups
- Batch processing with progress reporting for large datasets
- Configurable encoding detection for international text
Contributing
This skill serves as a reference implementation and contributions are welcome to demonstrate best practices:
- Follow PEP 8 coding standards
- Include comprehensive docstrings
- Add test cases with sample data
- Update documentation for any new features
- Ensure backward compatibility
Limitations
As a BASIC tier skill, some advanced features are intentionally omitted:
- Complex text analysis (sentiment, language detection)
- Advanced file format support (PDF, Word documents)
- Database integration or external API calls
- Parallel processing for very large datasets
This skill demonstrates the essential structure and quality standards required for BASIC tier skills in the claude-skills ecosystem while remaining simple and focused on core functionality.
