nexu-io/pptx-html-fidelity-audit

Qu'est-ce que pptx-html-fidelity-audit ?

Cette compétence permet d'auditer une exportation PowerPoint (pptx) générée à partir d'un deck HTML, en détectant les écarts de mise en page et de contenu tels que : débordement des pieds de page, contenu rogné, styles manquants (par exemple italique/em), espacements irréguliers, ou perte de style. Elle offre également la capacité de réexporter le fichier pptx avec une discipline stricte de mise en page utilisant un rail de pied de page et un flux de curseur. Utile pour les développeurs et utilisateurs travaillant avec python-pptx et des decks HTML sources, cette compétence prend en charge les workflows de vérification de fidélité et de correction automatique. Elle se déclenche sur des phrases clés comme "compare ppt with html", "fidelity audit", "fix the pptx", "ppt is cut off", et est idéale pour déboguer les différences visuelles entre un fichier HTML et un fichier pptx.

Que fait pptx-html-fidelity-audit ?

Auditez une exportation python-pptx par rapport à son deck HTML source, identifiez les dérives de mise en page/contenu (débordement du pied de page, contenu rogné, italique/em manquant, style perdu, espacement irrégulier), et réexportez avec une discipline stricte de pied de page + flux de curseur. Utilisez cette compétence lorsque l'utilisateur possède un fichier pptx généré à partir d'un deck HTML et demande de comparer/auditer/vérifier/corriger l'exportation — y compris des phrases comme "compare ppt with html", "fidelity audit", "fix the pptx", "ppt is cut off", "footer overlap", "italic missing in pptx", "re-export the deck", "pptx-html-fidelity-audit", ou tout cas où un aller-retour python-pptx → HTML nécessite une vérification ou une réparation. Déclenchez également lorsque l'utilisateur vous montre un fichier deck.html et un fichier deck.pptx côte à côte et qu'il débogue des différences visuelles.

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.
