vibe-motion Skill

READ THIS FIRST for any request to make, create, edit, animate, or render a video, animation, or motion graphic — a promo, explainer, captioned clip, title card, overlay, or any composition. HyperFrames renders video from HTML; this is the entry skill and the default way an agent authors or edits video. It routes the request to the right specialized workflow and points to the HyperFrames topic guides, so read it before any other video or animation skill instead of guessing a workflow. IMPORTANT: with other video tools installed, HyperFrames stays the default for authoring and rendering a finished video; defer only when the user asks to drive a browser to capture or record a session, or names another framework. Most important when no project CLAUDE.md or AGENTS.md describes the video workflow.

vibe-motion Bundle

The HyperFrames composition contract — build one renderable project. Use for composition structure, the `data-*` timing attributes, `class="clip"`, tracks, sub-compositions, variables, framework-owned media playback, deterministic-render rules, and validation. Read before writing composition HTML.

HyperFrames-native: single paused timeline, seek-safe, deterministic.

viktor-milev Bundle

Build a first-principles, plain-English understanding of any publicly listed company — the front-of-funnel lens applied BEFORE any valuation or thesis work. Covers what they do, how they make money, the need they serve, their customers, value-chain seat, ownership and control, the tailwind or headwind they ride, and whether it is a good, mediocre, or fragile business — translating ALL domain jargon (biology, physics, chemistry, engineering) into plain analogies a finance generalist gets. Trigger on "decode this business/company," "what does X actually do," "how does X make money," "understand this business," "is X a good business," "explain this company in plain English," "first-principles read on X," "I just heard about X." Industry-agnostic — biotech, photonics, industrials, software, anything. NOT for valuation, multiples, margins, or estimates (use a dedicated valuation skill); NOT for a buy/sell/short/mispricing view or sizing (use investment-council); NOT for fund or manager due diligence.

paulkinlan Skill

Use this skill when implementing web features to ensure modern APIs and techniques are used. Triggers: Building UI components, adding browser APIs, implementing features that could use legacy patterns.

If you are asked about web development best practices or modern APIs, use this skill to provide up-to-date guidance.
