nexu-io/pptx-html-fidelity-audit

O que é pptx-html-fidelity-audit?

Esta skill é projetada para desenvolvedores que usam python-pptx para converter decks HTML em apresentações PowerPoint. Ela automatiza a auditoria de fidelidade visual entre o HTML de origem e o PPTX gerado, detectando problemas comuns como estouro de rodapé, conteúdo cortado, itálico ou outros estilos perdidos, e espaçamento irregular. A skill suporta plataformas como Claude Code, Cursor e Codex, e funciona analisando ambos os arquivos (HTML e PPTX) para identificar discrepâncias. Após a auditoria, ela pode reexportar o PPTX com correções aplicadas, garantindo um layout mais próximo do original. Isso é útil em fluxos de trabalho onde a fidelidade da apresentação é crítica, como em relatórios automatizados, materiais de marketing ou documentação técnica.

Documentação

O que pptx-html-fidelity-audit faz?

Audita a exportação de um python-pptx em relação ao seu deck HTML de origem, identifica desvios de layout/conteúdo (estouro de rodapé, conteúdo cortado, itálico/ênfase ausente, estilos perdidos, espaçamento irregular) e reexporta com disciplina rigorosa de layout de trilho de rodapé + fluxo de cursor. Use esta skill sempre que o usuário tiver um .pptx gerado a partir de um deck HTML e pedir para comparar/auditar/verificar/corrigir a exportação — incluindo frases como "compare ppt com html", "auditoria de fidelidade", "corrigir o pptx", "ppt está cortado", "sobreposição de rodapé", "itálico ausente no pptx", "reexportar o deck", "pptx-html-fidelity-audit", ou qualquer caso onde uma ida e volta python-pptx → HTML precise de verificação ou reparo. Também acione quando o usuário mostrar um deck.html e um deck.pptx lado a lado e estiver depurando diferenças visuais.

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

nexu-io/chat-motion-overlay

Generate configurable chat motion overlays from a transcript or screenshot, including plain bubble scenes, app-style chat containers, optional device frames, preset or uploaded avatars, nickname display rules, and transparent-video-ready Remotion bundles. Use when Codex needs to create reusable short-form chat clips for Douyin, demo videos, story reenactments, social-message proof scenes, or embeddable alpha overlays for Hyperframe and Remotion workflows.

nexu-io/create-video-storyboard

Use this plugin when the user wants a video concept, storyboard, shot list, prompt pack, or render-ready motion brief for a product, campaign, or explainer.

nexu-io/design-brief

Parse a structured design brief written in I-Lang protocol format into a concrete design spec. Eliminates ambiguity from vague requests like "make it professional" by requiring explicit dimensions: palette, typography, layout, mood, density, and constraints. Trigger keywords: "design brief", "create a design brief", "ilang brief", "structured brief".

nexu-io/fal-lip-sync

Create talking head videos and lip sync audio to video via fal.ai. Useful for explainer avatars, multilingual dubbing previews, and social cuts.

nexu-io/frontend-design

Create distinctive, production-grade frontend interfaces with strong visual direction, polished typography, considered layout, and working HTML/CSS/JS or framework code. Use for websites, landing pages, dashboards, React components, application screens, and UI beautification.

nexu-io/hatch-pet

Create, repair, validate, preview, and package Codex-compatible animated pet spritesheets from character art, screenshots, generated images, or visual references. Use when a user wants to hatch a Codex pet, create a custom animated pet, or build a built-in pet asset with an 8x9 atlas, transparent unused cells, row-by-row animation prompts, QA contact sheets, preview videos, and pet.json packaging. This skill composes the installed $imagegen system skill for visual generation and uses bundled scripts for deterministic spritesheet assembly.

nexu-io/hyperframes

Create video compositions, animations, title cards, overlays, captions, voiceovers, audio-reactive visuals, and scene transitions in HyperFrames HTML. Use when asked to build any HTML-based video content, add captions or subtitles synced to audio, generate text-to-speech narration, create audio-reactive animation (beat sync, glow, pulse driven by music), add animated text highlighting (marker sweeps, hand-drawn circles, burst lines, scribble, sketchout), or add transitions between scenes (crossfades, wipes, reveals, shader transitions). Covers composition authoring, timing, media, and the full video production workflow. For CLI commands (init, lint, preview, render, transcribe, tts) see the hyperframes-cli skill.

nexu-io/remotion

Programmatic video creation with React. Useful for branded explainers, social cuts, dashboards-to-video, and reproducible motion graphics.

nexu-io/social-media-dashboard

Creator-facing social media analytics dashboard in a single HTML file. A platform switcher (X / LinkedIn / YouTube / Instagram), a row of KPI cards (followers, engagement rate, likes, reposts), a follower-growth chart, a "top post this week" preview, and a trending topics / top comments side panel. Use when the brief mentions a "social media dashboard", "creator analytics", "social analytics", or names specific platforms (X, Twitter, LinkedIn, YouTube, Instagram, TikTok) together with metrics like followers, engagement, likes, reposts.

nexu-io/sora

Generate, remix, and manage short video clips via OpenAI's Sora API. Useful for cinematic shots, b-roll, and rapid concept video iteration.

nexu-io/ui-ux-pro-max

Catalog-only UI/UX Pro Max entry. The full upstream templates, data, and search workflow are not bundled in Open Design.

nexu-io/video-hyperframes

Hyperframes / Remotion-compatible continuous frame animation with autoplay support.

nexu-io/video-shortform

Short-form video generation skill — 3-10 second clips for product reveals, motion teasers, ambient loops. Defaults to Seedance 2 but works the same with Kling 3 / 4, Veo 3 or Sora 2. Output is one MP4 saved to the project folder. When the workspace also ships an interactive-video / hyperframes skill, prefer composing several short shots into a single timeline rather than one long monolithic clip.

nexu-io/video-template-frame-bold-poster

Use this plugin when the user wants a "Bold Poster Frame" HyperFrames motion video — A 1970s European editorial poster in motion — a red rule draws across, a giant tilted figure drops in, a three-line headline rises line-by-line, an italic serif standfirst fades.

nexu-io/video-template-frame-bold-signal

Use this plugin when the user wants a "Bold Signal Frame" HyperFrames motion video — Bold colored card on a dark gradient — big section number, nav breadcrumb, orange card sliding in, title rising.

nexu-io/video-template-frame-build-minimal

Use this plugin when the user wants a "Build Minimal Frame" HyperFrames motion video — Luxury-minimal whitespace hero — single word reveals letter by letter, warm-gold hairline, breathing indicators.

nexu-io/video-template-frame-creative-voltage

Use this plugin when the user wants a "Creative Voltage Frame" HyperFrames motion video — Electric split with hand-drawn script — offset panels slide in, display title rises with an outlined word, script strokes itself in.

nexu-io/video-template-frame-data-chart-nyt

Use this plugin when the user wants a "NYT-Style Data Chart Frame" HyperFrames motion video — NYT-newsroom typography, staggered reveal animation, and editorial-grade charts (line, bar, or range band).

nexu-io/video-template-frame-data-rollup

Use this plugin when the user wants a "Data Rollup Frame" HyperFrames motion video — A native Remotion data frame — bars grow from zero by real data via spring physics while the figures roll 0→target in sync.

nexu-io/video-template-frame-product-promo-30s

Use this plugin when the user wants a "Product Promo · 30s" HyperFrames motion video — Multi-scene 30-second product promo: problem-type intro, brand reveal, benefits flowchart, product surfaces, value pillars, foundation, CTA outro. Forked from Nate Herk's hyperframes-student-kit (linear-promo-30s); brand-specific copy + assets replaced with generic placeholders.
