## What it does

\`sample-text-processor` acts as a test fixture for `skill_validator.py` and `script_tester.py`. It is a minimal BASIC-tier layout. The frontmatter includes only the fields Claude Code reads. Its command-line script, `text_processor.py`, tracks word frequency and changes text casing.

The codebase contains dedicated classes for processing logic and output formatting. You run single-file inspections through `analyze`, or batch-process directories. The script outputs terminal text or raw JSON data. Text encoding defaults to `utf-8`.

Running this tool requires Python 3.7 or newer with no external packages. The author intentionally omitted complex natural language features and binary document readers. Feeding a PDF or Word document into the script triggers an encoding failure.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add alirezarezvani/claude-skills
```
In the agent chat (not a shell):
```text
/plugin install engineering-advanced-skills@claude-code-skills
```
This installs the whole engineering-advanced-skills plugin with all its skills

2. **Skills CLI (Vercel)**
```bash
npx skills add alirezarezvani/claude-skills --skill sample-skill -a claude-code
```

3. **Manually: put the files in place**
- File: `~/.claude/skills/sample-skill/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/sample-skill/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/sample-skill/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/sample-skill/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install alirezarezvani/claude-skills sample-skill
```

2. **Manually: put the files in place**
- File: `.github/skills/sample-skill/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/alirezarezvani/claude-skills --path engineering/skills/skill-tester/assets/sample-skill
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/sample-skill/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/alirezarezvani/claude-skills/tree/HEAD/engineering/skills/skill-tester/assets/sample-skill/SKILL.md

## When to use it
- validate skill verification tools against a reference manifest layout
- calculate word frequency and line totals for plain text documents
- batch transform text files into uppercase, lowercase, or title case
- generate text metrics directly in JSON format for automated workflows

## Example prompts
- Run `text_processor.py analyze document.txt` and report the most frequent words
- Convert headings in `chapter.txt` to title case using `text_processor.py transform`
- Batch process the `docs/` directory with `text_processor.py` and output results to `batch_results.json`

# Sample Text Processor

This file is the fixture skill_validator.py and script_tester.py run against.
It is deliberately minimal. Keep its frontmatter valid YAML and limited to the
fields Claude Code reads: anything else here gets copied into new skills by
authors treating it as a template.

Tier: BASIC. Dependencies: none, Python standard library only.

## 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
```bash
python text_processor.py analyze document.txt
python text_processor.py analyze document.txt --output results.json
```

### Text Transformation
```bash
python text_processor.py transform document.txt --mode uppercase
python text_processor.py transform document.txt --mode title --output transformed.txt
```

### Batch Processing
```bash
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
```bash
$ 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)
```
