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.
Turn a prompt or an existing image into a polished multi-scene cinematic short video using Seedance for clip generation, uguu.se for file hosting, and FFmpeg for last-frame extraction and crossfade stitching. Supports two modes — PARALLEL (multiple scenes from the same reference image, concurrent, ~3 min total) and CHAIN (each scene starts on the last frame of the previous scene, sequential, ~3 min per scene, produces one continuous long take). Use this skill whenever the user wants to "make a video from an image", "animate this picture", "generate video scenes", "create a cinematic short", "stitch AI videos together", "make a long continuous video", "chain AI clips", or any workflow that goes from one reference image to a multi-clip stitched video. Also trigger when the user mentions Seedance, image-to-video, video stitching, crossfades between clips, frame chaining, last-frame continuity, or wants to turn a generated image into motion.

Production pipeline for mathematical and technical animations using Manim Community Edition. Creates 3Blue1Brown-style explainer videos, algorithm visualizations, equation derivations, architecture diagrams, and data stories. Use when users request: animated explanations, math animations, concept visualizations, algorithm walkthroughs, technical explainers, 3Blue1Brown style videos, or any programmatic animation with geometric/mathematical content.
Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
Use when implementing any feature or bugfix, before writing implementation code
Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
Run a premortem on any plan, launch, product, hire, strategy, or decision. Assumes it already failed 6 months from now and works backward to find every reason why. MANDATORY TRIGGERS: 'premortem this', 'premortem my', 'run a premortem', 'what could kill this', 'stress test this plan', 'find the blind spots'. STRONG TRIGGERS: 'what could go wrong', 'poke holes in this', 'devil's advocate this'. Do NOT trigger on simple feedback requests or factual questions.
