Full product-market fit cycle for one product — from initial hypothesis to post-launch metrics. 10 stages: setup → hypothesis (7 dimensions) → market research → risk synthesis → DVF validation → interview prep → field → interview synthesis → MVP → metrics (Sean Ellis + retention + Levels of PMF) → iterate. Resumes between sessions based on the project folder state. Bilingual (English + Russian) — picks the language during first-run setup. TRIGGER on ANY: - "do PMF for [product]" / "I need product market fit for X" / "PMF [name]" - "start PMF cycle" / "I want to go through PMF" / "help me validate [idea]" - "continue PMF" / "continue PMF [name]" - "check PMF" / "what stage is my PMF at" / "show my PMF projects" - "is my product ready to launch" - "сделай PMF для [продукта]" / "нужен product market fit для X" / "PMF [имя]" - "запусти PMF цикл" / "хочу пройти PMF" / "помоги валидировать [идею]" - "продолжаем PMF" / "продолжай PMF [имя]" - "проверь PMF" / "на каком этапе у меня PMF" / "покажи мои PMF проекты" - "
Record architecture decisions in a project's ADR log. Creates the ADR file for new projects, appends new entries, and marks old decisions as superseded. Use this skill whenever an architectural or design decision is made during a session: choosing a technology, database schema, data format, API design, file structure, deployment strategy, or any choice that affects how the project is built. Also use at session end ("завершаем сессию") if any decisions were made. Triggers: "запиши ADR", "architecture decision", "запиши решение", "ADR", "зафиксируй решение", or when CLAUDE.md session-end checklist detects architectural decisions were made.
Write detailed, production-ready prompts for AI image generation (Midjourney, DALL-E, Flux, Stable Diffusion, etc.). Use when the user needs an illustration, image, or visual asset for any context — website hero, card, social media post, presentation slide, document cover, infographic background, or any other visual. Triggers on requests like "need an image", "write a prompt for illustration", "make me a picture", "generate an illustration prompt", "need a visual", or when the user mentions needing artwork for a page/project. Also use when the user says "illustration prompt", "prompt for image", or asks you to describe what an image should look like. Works for ANY art style — voxel art, isometric, flat, watercolor, photorealistic, 3D render, line art, collage, and more. Russian triggers: "нужна иллюстрация", "промпт для картинки", "сделай картинку", "нужен визуал", "напиши промпт для изображения".
Generate self-contained HTML pages that visually explain systems, data stories, investigations, editorial workflows, and code changes. Use when the user asks for diagrams, architecture views, visual diffs, data tables, timelines, source maps, or any structured visualization that would be painful to read as terminal output. Also activates for tables with 4+ rows or 3+ columns. Adapted from nicobailon/visual-explainer with journalism, newsroom, and academic design sensibilities.
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.
You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
Run a full UX audit on any website: Nielsen heuristics, conversion, content, technical quality, information architecture. Produces a prioritized report with evidence-based findings and actionable recommendations. Use when asked to review a site, check a landing page, find UX problems, evaluate usability, assess conversion, or anything like "what's wrong with this site", "review the website", "audit UX", "check the forms", "why isn't the site converting".
Use when choosing a narrative strategy before writing any text — articles, pitches, essays, reports, personal posts. Also use mid-writing to check tone, get next-block guidance, or shift narrative. Triggers: «writing guru», «подбери нарратив», «какой нарратив выбрать», «нарративная стратегия», «narrative strategy», «guru, проверь фрагмент», «guru, что дальше», «guru, хочу сменить тональность».
