- Brand Guidelines DocWrites a brand guidelines document - personality traits with is/is-not definitions, voice principles, a tone-by-context matrix, writing mechanics, a say-this-not-that word list, and visual usage rules - all made concrete with do/don't examples. Use when someone asks "write our brand guidelines", "document our voice and tone", "make a style guide the whole team can follow", or teams keep producing off-brand copy and design. Do NOT use for inventing the brand name itself - use brand-naming instead; for organizing messaging by audience and claim, use messaging-hierarchy.Writing
- UI/UX Pro Max50+ visual styles, 161 color palettes, 57 font pairings across React, Next.js, SwiftUI, React Native, and more.Design
- LinkedIn Post WriterWrite LinkedIn posts built for the feed - a hook that survives the two-line truncation, scannable one-idea-per-line structure, a comment-bait close, and first-hour engagement moves. Use when someone asks "write a LinkedIn post about this", "punch up my LinkedIn hook", "why did my post get no reach", or "turn this win into a LinkedIn post". Do NOT use for Twitter/X threads - use tweet-thread-builder instead. Do NOT use for scheduling across a monthly calendar - use social-content-calendar instead.Writing
- Email Newsletter ProWrite recurring email newsletters - subject lines that earn the open, preview text that extends them, a body structure readers finish, and cadence rules that keep the list healthy. Use when someone asks "write my newsletter", "give me subject line options", "why is my open rate dropping", "should I send weekly or monthly", or "help me structure this issue". Do NOT use for automated onboarding or behavior-triggered sequences - use email-drip-builder instead. Do NOT use for inbox placement and spam-folder problems - use email-deliverability instead.Writing
- Git Commit WriterGenerates conventional commit messages from diffs with scope, breaking change flags, and issue refs.Coding
- Remotion SetupScaffolds a new Remotion video project wired for Claude Code Agent Skills - Node check, create-video scaffold, skills install, folder conventions, Google Fonts, and a smoke-test render. Use whenever someone wants to start making videos with Remotion and Claude, even just "make product videos with Claude."Coding
- Remotion RenderRenders a Remotion composition to MP4 and runs the edit-and-re-render loop - CLI render commands, 1080p/4K/9:16 presets, concurrency tuning, codec selection, batch variants from a JSON data file, and Lambda for cloud rendering. Use when someone says "render this Remotion video", "export the composition to MP4", "the animation is too fast, fix and re-render", "batch render one video per customer", or "move rendering to Lambda". Do NOT use for authoring or restructuring scenes, animations, or components - use remotion-compose instead; do NOT use for project scaffolding and initial setup - use remotion-setup instead. This skill owns everything from a finished composition to a delivered file.Coding
- Remotion ComposeTurns a natural-language video brief into a complete, ready-to-preview Remotion composition - extracts duration, scenes, brand colors, aspect ratio, and real copy; plans the frame budget; and writes data-driven React/TypeScript using useCurrentFrame, interpolate, spring, AbsoluteFill, and Sequence, registered in Root.tsx. Use when someone says "build a 20-second product demo video", "animate a feature walkthrough", "write the Remotion code for this marketing clip", or wants a scene-by-scene composition they can scrub in Studio. Do NOT use for rendering, iterating, or batching the finished MP4 - use remotion-render instead - or for installing and scaffolding the project - use remotion-setup instead.Coding
