    Dev ReadabilityAgentsToolsHub

    Compute readability metrics for a block of text: Flesch Reading Ease score, Flesch-Kincaid grade level, and word/sentence/syllable statistics. Deterministic formulas — useful for checking documentation, prompts and agent output clarity. Use this when an agent needs to flesch reading-ease and grade level for any text.

    Dev Regex TesterAgentsToolsHub

    Test a regular expression against text and see every match: the matched substring, its index, and all capture groups. Deterministic — the same pattern and text always produce the same result, unlike LLM-simulated regex matching. Use this when an agent needs to pattern + text → every match, group and index.
