Text: Template and Similarity Processing (High Priority)

[jwesleye]

Template/Placeholder Processing

• Variable substitution: Support ${variable}, {{variable}}, {variable} formats
• Safe template rendering: Validate variables and prevent injection
• Conditional text blocks: Handle if/else logic in templates
• Nested variable support: Complex object property access
• Default value handling: Fallback values for missing variables

Text Similarity and Comparison

• Fuzzy string matching: Find approximate matches with configurable threshold
• Text diff generation: Character and word-level differences
• Similarity scoring: Multiple algorithms (Levenshtein, Jaccard, cosine)
• Duplicate detection: Identify similar or identical text blocks
• Best match finding: Select closest match from list of options

Content Summarization and Analysis

• Intelligent truncation: Preserve meaning while reducing length
• Key phrase extraction: Identify important terms and concepts
• Word frequency analysis: Count and rank word usage
• Text metrics: Character/word/sentence counts, readability scores
• Content classification: Detect text type and structure

Format Detection and Validation

• Auto-format detection: Identify markdown, JSON, XML, CSV, etc.
• Structure validation: Verify format compliance
• Format conversion hints: Suggest appropriate processing functions
• Content type detection: Distinguish between prose, lists, data, etc.
