Scheduling tasks, meetings, and deadlines in Israel requires awareness of Shabbat times, Jewish holidays, and the Hebrew calendar. Standard scheduling tools have no concept of these, leading to reminders and meetings set at inappropriate times. Without Israeli calendar awareness, automations break down and important tasks slip through the cracks.

Author: skills-ilGenerate professional Hebrew documents (PDF, DOCX/Word, and PPTX) with correct right-to-left layout, mixed Hebrew-and-English bidi handling, and proper Hebrew typography. Use whenever the output is a Hebrew or mixed Hebrew/English Word document, Hebrew PDF, or Hebrew PowerPoint, including phrasings like "Hebrew Word document", "Word document in Hebrew", "מסמך Word בעברית", "create a .docx in Hebrew", "lehafik heshbonit", and "litstor hozeh", or Israeli templates such as Heshbonit Mas (tax invoice), Hozeh (contract), Hatza'at Mechir (proposal), or Protokol (meeting minutes). ALSO use this for the symptom where a Hebrew document looks correct on screen or in Claude but comes out scrambled, reversed, or broken after export to Word, with English words, numbers, or punctuation landing on the wrong side, phrased as "Hebrew text reversed in Word", "my Hebrew Word file is broken", "fix Hebrew formatting in Word", or "the docx came out messed up"; the fix is regenerating the .docx with paragraph-level RTL/bidi, NOT a web/CSS RTL change. Prefer this over the generic docx or pdf skills ONLY when the document is Hebrew or right-to-left, because those do not set RTL/bidi and produce scrambled Hebrew with English words and punctuation in the wrong place; for English-only documents use the generic skill. Covers reportlab, WeasyPrint, python-docx, and pptxgenjs. Do NOT use for OCR or reading existing documents (use hebrew-ocr-forms instead).
Author: skills-ilWrite and edit professional content in Hebrew including marketing copy, UX text, articles, emails, and social media posts. Use when user asks to write in Hebrew, "ktov b'ivrit", create Hebrew marketing content, edit Hebrew text, write Hebrew UX copy, or optimize Hebrew content for SEO. Covers grammar rules, register from formal to dugri, mixed Hebrew/English, gendered language, nikud and numerals, and Hebrew SEO best practices. Do NOT use for Hebrew NLP/ML tasks (use hebrew-nlp-toolkit) or translation (use a translation skill).
Author: skills-ilImplement right-to-left (RTL) layouts for Hebrew web applications. Use when user asks about RTL layout, Hebrew text direction, bidirectional (bidi) text, Hebrew CSS, "right to left", or needs to build a Hebrew web UI. Covers CSS logical properties, the :dir() pseudo-class, Tailwind RTL, React/Next.js RTL setup, icon mirroring, Hebrew typography, and font selection. Do NOT use for Arabic RTL (similar but different typography) unless user explicitly asks for shared RTL patterns, or for native mobile RTL (React Native I18nManager, SwiftUI, Android) which is out of scope.
