App Store screenshot generation skill with two workflows: (A) AI-powered: fetches app metadata via `asc` CLI, analyzes screenshots with Claude vision, writes a ScreenPlan JSON, then generates final marketing screenshots via Gemini (`asc app-shots generate`), and optionally translates them (`asc app-shots translate`). (B) HTML-based (deterministic): writes a CompositionPlan JSON with precise device placement, text overlays, and backgrounds, then runs `asc app-shots html` to produce a self-contained HTML page with real device mockup frames and client-side PNG export — no AI needed. Use this skill when: (1) User asks to "create App Store screenshots" or "generate screenshot plan" (2) User asks to "make an HTML screenshot page" or "compose screenshots with mockups" (3) User mentions "asc-app-shots", "app-shots html", "composition plan", or screenshot marketing (4) User wants deterministic, reproducible screenshot layouts with device mockups (5) User wants AI-generated screenshots via Gemini
After Effects animation rendering for web and React applications.

Aids in writing Mojo code that interoperates with Python using current syntax and conventions. Use this skill in addition to mojo-syntax when writing Mojo code that interacts with Python, calls Python libraries from Mojo, or exposes Mojo types/functions to Python.

YC Office Hours — two modes. Startup mode: six forcing questions that expose demand reality, status quo, desperate specificity, narrowest wedge, observation, and future-fit. Builder mode: design thinking brainstorming for side projects, hackathons, learning, and open source. Saves a design doc. Use when asked to "brainstorm this", "I have an idea", "help me think through this", "office hours", or "is this worth building". Proactively suggest when the user describes a new product idea or is exploring whether something is worth building — before any code is written. Use before /plan-ceo-review or /plan-eng-review.
