## 📝 Step 3: Update Module Documentation

### **Update README.md**
Replace the template content in `README.md`:

```markdown
# Text Analysis Module

The Text Analysis module provides comprehensive text analysis capabilities for the Codomyrmex ecosystem. It offers word counting, readability metrics, sentiment analysis, and integration with other Codomyrmex modules.

## Features

- **Basic Text Metrics**: Word count, character count, sentence count, paragraph count
- **Readability Analysis**: Flesch Reading Ease score calculation
- **Sentiment Analysis**: Basic sentiment detection and scoring
- **File Analysis**: Direct analysis of text files
- **Codomyrmex Integration**: Full logging and error handling integration

## Quick Start

```python
from codomyrmex.text_analysis import analyze_text

# Analyze text directly
text = "This is a sample text for analysis. It contains multiple sentences!"
result = analyze_text(text)

print(f"Words: {result.word_count}")
print(f"Readability Score: {result.readability_score}")
print(f"Sentiment: {result.sentiment}")
```

## API Overview

### Classes

- `TextAnalyzer`: Main analysis class with full configuration options
- `TextAnalysisResult`: Data class containing all analysis results

### Functions

- `analyze_text(text, enable_sentiment=True)`: Analyze text string
- `analyze_file(file_path, enable_sentiment=True)`: Analyze text file

## Integration Examples

### With Data Visualization
```python
from codomyrmex.text_analysis import analyze_file
from codomyrmex.data_visualization import create_bar_chart

# Analyze multiple documents
results = []
files = ['doc1.txt', 'doc2.txt', 'doc3.txt']

for file in files:
    result = analyze_file(file)
    results.append(result.readability_score)

# Visualize readability scores
create_bar_chart(
    categories=[f"Doc {i+1}" for i in range(len(files))],
    values=results,
    title="Document Readability Comparison",
    y_label="Readability Score",
    output_path="readability_comparison.png"
)
```

### With AI Code Editing
```python
from codomyrmex.text_analysis import analyze_text
from codomyrmex.agents import generate_code_snippet

# Analyze text and generate improvements
text = "This text needs improvement."
analysis = analyze_text(text)

if analysis.readability_score < 50:
    improved_text = generate_code_snippet(
        f"Improve the readability of this text: {text}",
        "text"
    )
```

## Requirements

- Python 3.10+
- Standard library modules (re, statistics, pathlib, dataclasses)
- Codomyrmex logging_monitoring module

For sentiment analysis:
- textblob (optional, for advanced sentiment analysis)

## Security Considerations

- File path validation prevents directory traversal attacks
- Input sanitization for all text analysis operations
- Memory usage monitoring for large text files
- No external network requests required for basic functionality

## Performance Notes

- Optimized for text files up to 10MB
- Sentiment analysis adds ~20% processing time
- Memory usage scales linearly with text size
- Supports batch processing for multiple files
```

### **Update API_SPECIFICATION.md**
Replace the template content:

```markdown
# Text Analysis API Specification

## Overview

The Text Analysis module provides programmatic access to comprehensive text analysis capabilities through a clean, well-documented API.

## Classes

### TextAnalyzer

Main class for text analysis operations.

#### Constructor

```python
TextAnalyzer(enable_sentiment: bool = True)
```

**Parameters:**
- `enable_sentiment` (bool): Enable sentiment analysis capabilities

#### Methods

##### analyze_text(text: str) -> TextAnalysisResult

Analyze text content comprehensively.

**Parameters:**
- `text` (str): Text content to analyze

**Returns:**
- `TextAnalysisResult`: Complete analysis results

**Raises:**
- `ValueError`: If text is empty or None

##### analyze_file(file_path: str) -> TextAnalysisResult

Analyze text from a file.

**Parameters:**
- `file_path` (str): Path to text file

**Returns:**
- `TextAnalysisResult`: Complete analysis results

**Raises:**
- `FileNotFoundError`: If file doesn't exist
- `IOError`: If file cannot be read

### TextAnalysisResult

Data class containing analysis results.

**Attributes:**
- `word_count` (int): Number of words
- `character_count` (int): Total character count including spaces
- `character_count_no_spaces` (int): Character count excluding spaces
- `sentence_count` (int): Number of sentences
- `paragraph_count` (int): Number of paragraphs
- `average_words_per_sentence` (float): Average words per sentence
- `readability_score` (float): Readability score (0-100, higher = more readable)
- `sentiment` (Optional[str]): Sentiment classification ("positive", "negative", "neutral")
- `sentiment_score` (Optional[float]): Sentiment score (-1.0 to 1.0)

## Functions

### analyze_text(text: str, enable_sentiment: bool = True) -> TextAnalysisResult

Convenience function for direct text analysis.

### analyze_file(file_path: str, enable_sentiment: bool = True) -> TextAnalysisResult

Convenience function for file analysis.

## Usage Examples

### Basic Usage

```python
from codomyrmex.text_analysis import TextAnalyzer

# Initialize analyzer
analyzer = TextAnalyzer(enable_sentiment=True)

# Analyze text
text = "Your text content here."
result = analyzer.analyze_text(text)

# Access results
print(f"Words: {result.word_count}")
print(f"Readability: {result.readability_score}")
```

### Batch Processing

```python
from codomyrmex.text_analysis import TextAnalyzer
from pathlib import Path

analyzer = TextAnalyzer()

# Process multiple files
results = {}
for file_path in Path("documents/").glob("*.txt"):
    results[file_path.name] = analyzer.analyze_file(str(file_path))

# Compare readability
for filename, result in results.items():
    print(f"{filename}: {result.readability_score:.1f}")
```

## Error Handling

All functions and methods follow Codomyrmex error handling conventions:

- Use specific exception types
- Provide detailed error messages
- Log errors using codomyrmex.logging_monitoring
- Raise exceptions rather than returning error codes

## Thread Safety

The TextAnalyzer class is thread-safe for read operations. Multiple threads can safely call analysis methods on the same instance.

## Performance Characteristics

- Time complexity: O(n) where n is text length
- Memory complexity: O(n) for text processing
- Typical performance: ~1000 words/second on modern hardware
- File size limits: Recommended maximum 10MB per file
```
