Identifies and removes AI writing patterns to make text sound natural and human-written. Use when user says "humanise this", "make this sound less AI", "this reads like a robot wrote it", "de-AI this text", "remove AI patterns", "make this more natural", "clean up this AI-generated text". Detects and fixes 29 patterns based on Wikipedia's "Signs of AI writing" guide - inflated language, promotional tone, AI vocabulary, em dash overuse, filler phrases, sycophantic tone, placeholder text, formulaic structure, thematic breaks. Do NOT use for grammar-only proofreading, spell checking, or rewriting text that is already clearly human-written.
Fast, zero-AI text extraction from PDFs that have a text layer (digitally created PDFs from Word, Typst, WeasyPrint, wkhtmltopdf, LaTeX, etc). Uses pymupdf (fitz) - instant and deterministic. Use when you need to quickly pull raw text from a known text-layer PDF, e.g. "extract text from this PDF", "read this PDF", "get the content of", "what does this PDF say", "quickly read this PDF". Do NOT use for scanned/image PDFs or when you need structured output (tables, headings, OCR, AI analysis) - use the pdf-processing-pro skill in this plugin for those cases.

Generate comprehensive Product Requirement Plans (PRPs) for feature implementation with thorough codebase analysis and external research. Use when the user requests a PRP, PRD, or detailed implementation plan for a new feature. Conducts systematic research, identifies patterns, and creates executable validation gates for one-pass implementation success. Do NOT use for client discovery, requirements gathering, or scope definition - those need a separate clarification pass before the PRP step.
