String

This gives Claude five focused string operations: analyze_string returns readability metrics like Flesch-Kincaid scores and word frequency, transform_string handles extraction and masking of emails, URLs, and phone numbers plus whitespace cleanup, diff_strings compares text at character, word, or line level, render_template processes mustache-style variables with conditionals and loops, and generate_slug creates URL-friendly identifiers with transliteration. Reach for this when you need text analysis beyond basic manipulation, especially for content processing pipelines where you want readability assessment, structured diffs, or template rendering without pulling in separate libraries for each task.
