* feat(cli): add website capture with AI-powered DESIGN.md generation Adds `hyperframes capture <url>` command that extracts a complete design system from any website, producing AI-agent-ready output: - Full-page screenshot (lazy-load aware, nav at top) - AI-generated DESIGN.md via Claude API (colors, typography, elevation, components, do's/don'ts) with programmatic asset catalog (136+ assets with HTML context annotations like img[src], css url(), link[rel=preload]) - CSS-purged compositions (87% size reduction via PurgeCSS) - HTML-prettified compositions (one-tag-per-line for AI readability) - CLAUDE.md + .cursorrules auto-generated for AI agent instructions - Asset deduplication (srcset variants) and tracking pixel filtering * feat(cli): add gemini 3.1 pro, playwright screenshots, replica refinement - switch to gemini 3.1 pro (gemini-3.1-pro-preview) with claude fallback - playwright for full-page screenshots (fixes puppeteer gradient/fixed bugs) - replica refinement loop: generate, screenshot, compare, fix - extract inline svgs (50 max, 10kb each) to assets/svgs/ - extract visible text in dom order for content accuracy - detect js libraries (gsap, three.js, scrolltrigger) via globals - improved asset catalog grouping and naming - reverse-engineered aura system prompt documentation - comprehensive session handoff doc Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: update session handoff with slack research findings - key finding: team already wants DESIGN.md integration (James, Bin, Vance) - skills quality matters enormously - must invoke /hyperframes-compose - eval infrastructure exists (Abhay's dashboards, Teodora's 78-criteria guide) - templates at templates/ need study before finalizing skill - session handoff updated with critical next steps * refactor(cli): simplify capture pipeline, remove replica generator * feat(capture): add Lottie detection and WebGL shader extraction Captures Lottie animations via network interception and WebGL shader source via gl.shaderSource hooking during site crawl. Updates website-to-hyperframes skill with asset planning guidance, Lottie/shader reading instructions, and stronger creative direction for scene planning. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * refactor(capture): clean pipeline + shader-first creative workflow Capture pipeline: - Remove dead deps (puppeteer-extra, stealth plugin, duplicate devDeps) - Remove duplicate generateAgentPrompt() call (first lied about DESIGN.md) - Remove dead canvas-to-image code in htmlExtractor (post canvas removal) - Parallelize image downloads (batches of 5 via Promise.allSettled) - Fix pre-existing TS error (match[1] guard in font downloader) - Default capture output to captures/<hostname> Skill creative overhaul: - Add shader transition selection to creative director step (Step 4) - Add shader wiring instructions to engineer step (Step 5) - Replace 4-line energy modifiers with visual vocabulary table - Strip rigid scene-by-scene templates from video-recipes.md - Strip example fill data from scene plan tables - Add "read transition refs before planning" instruction - Add creative ambition language ("how the hell did they make this") Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: add skill architecture redesign spec Comprehensive redesign of website-to-hyperframes skill and capture pipeline based on code review findings and Claude Code architecture research. Key changes: remove AI auto-generation, restructure skill into phases, embed shader boilerplate in scaffold, fix color format. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: add implementation plan for skill architecture redesign 13-task plan covering: capture pipeline cleanup (remove AI generation, fix colors to HEX, add asset descriptions, shader-ready scaffold), skill restructuring (4 phases with artifact gates), and compose skill Visual Identity Gate upgrade. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * refactor(capture): remove AI auto-generation and SDK dependencies * fix(capture): convert extracted colors to HEX format * refactor(capture): remove AI key path, add asset descriptions generator * refactor(capture): update agent prompt, remove hasDesignMd, add asset descriptions * feat(capture): pre-wire shader transitions in index.html scaffold * chore: remove duplicate visual-styles.md (canonical is in hyperframes/) * refactor(skill): rewrite website-to-hyperframes as phase-based orchestrator * feat(skill): add Phase 1 understand reference * feat(skill): add Phase 2 design reference with full DESIGN.md schema * feat(skill): add Phase 3 creative direction reference * feat(skill): add Phase 4 build reference with inline shader example * feat(skill): upgrade Visual Identity Gate to produce full DESIGN.md * docs: update CLAUDE.md skill references for phase-based workflow * fix: address code review findings - Remove orphaned `false` argument in generateAgentPrompt call (critical: was shifting hasLottie, hasShaders, catalogedAssets parameters) - Add HSL color handling in rgbToHex via temp element resolution - Remove build artifact commit section from phase-4-build.md - Fix __GSAP_TIMELINE reference to __timelines Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(capture): regex double-escape + simplify scaffold + fix asset descriptions - Double-escape regex in tokenExtractor template literal (\s→\\s, \d→\\d, \(→\\() so browser receives valid regex patterns via page.evaluate() - Simplify index.html scaffold: scene slots + audio + timeline + comment pointing to shader-setup.md reference (no broken inline shader boilerplate) - Fix asset descriptions: use CatalogedAsset.contexts/notes instead of nonexistent htmlContext field Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: code review — 16 bugs, 7-step skill rewrite, cleanup Code fixes: - snapshot.ts: path traversal guard, browser leak (try/finally), div-by-zero for --frames 1, port bind error handling, rAF-based render settle - index.ts: remove invalid thinkingConfig for gemini-2.5-flash, fix Gemini batch/rate-limit comments, fix video preview viewport y-coordinate - tokenExtractor.ts: remove dead seen[si] dedup code - gsap.ts: index ALL classes for inline-style transform conflict detection Skill architecture rewrite (4-phase → 7-step): - Replace phase-1 through phase-4 with step-1 through step-7 - Add techniques.md (10 visual techniques with code patterns) - Fix /hyperframes-compose → /hyperframes (skill doesn't exist) - Fix captures/arc-browser reference → shader-setup.md (file doesn't exist) - Fix step-7 hardcoded captures/stripe path - Document Gemini API free/paid rate limits in step-1 Cleanup: - CLAUDE.md: restore from Stripe-capture overwrite, update 4-phase → 7-step - .gitignore: add PR #267 skills (hyperframes-animation-map, hyperframes-contrast) - Delete old phase-*.md, animation-recreation.md, tts-integration.md Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * chore: remove dev artifacts, research docs, wrong lockfiles Remove files that shouldn't ship in this PR: - docs/research/ (aura analysis, prompt catalogs) - docs/session-*.md, docs/SESSION-HANDOFF.md (dev notes) - docs/superpowers/ planning and spec docs - pnpm-lock.yaml at root and cli (repo uses bun, not pnpm) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(CLAUDE.md): align with main — slim format, add website-to-hyperframes mention Main PR #283 removed the full skills table from CLAUDE.md and moved it to AGENTS.md. Align with that decision: use main's slim dev-focused format, fix pnpm→bun references, add one-line /website-to-hyperframes pointer. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(cli): add capture command to help groups The capture command was registered in cli.ts but missing from the help groups, so it wouldn't appear in `hyperframes --help`. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * style: format skill reference files (oxfmt) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: regenerate bun.lock after rebase The lockfile was stale after rebasing onto main — bun install --frozen-lockfile failed in CI because new dependencies (google/genai, patchright, purgecss) weren't reflected in the lockfile. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: address PR review comments + improve capture quality Review fixes (16 comments from jrusso1020 + vanceingalls): - screenshotCapture: remove Playwright dep, use Puppeteer for all screenshots - screenshotCapture: dynamic screenshot count based on page height (30% overlap) - snapshot.ts: fix duration() function-vs-property bug, cross-platform path guard - htmlExtractor: fix code injection via parameterized evaluate - index.ts: video preview re-measures position after scroll, .env file loading - capture.ts: BLOCKED.md on timeout failures - gsap.ts: 5 inline-style lint tests added (all pass) - Remove Playwright, patchright deps; @google/genai to optionalDependencies - Gitignore: generic patterns instead of 20 hardcoded directories - Remove asset-sourcing.md, video-recipes.md (unused, duplicated guidance) Capture quality improvements (tested on 10+ websites): - Color extraction: canvas-based oklch/lab resolver, pixel sampling via elementFromPoint, broad sweep for accent colors, gradient/shadow extraction - Section detection: broadened selectors for div-based layouts, height cap to skip page-level wrappers, parent bg walkup for dark sites - Font downloads: cap 6 per family / 30 total (Cal.com: 306→30) - CTA detection: text pattern matching + nav context filtering - Heading text: innerText with whitespace normalization - Gemini captioning: maxOutputTokens 100→300, .env auto-loading - .env.example updated with GEMINI_API_KEY docs - TTS ranking: Kokoro first with Python 3.10+ note * fix: address PR review comments + improve capture quality Review round 2 fixes (jrusso1020 + vanceingalls): - verify/index.ts: add path traversal guard (relative + isAbsolute) - verify/index.ts: fix sections[i] undefined typecheck error (CI green) - index.ts: escape Lottie JSON with \u003c to prevent </script> breakout - step-4-storyboard: fix technique count contradiction (2-3 per beat, not across whole video) - step-6-build: perspective tilt uses gsap.set() instead of CSS transform (avoids GSAP overwrite conflict) - step-1-capture: reorder — command first, Gemini note after (zero-config is the default path, API key is optional enhancement) - step-7-validate: add tsx fallback for snapshot command - step-3-script: vary hook patterns, don't default to number every time - assetDownloader: exempt SVGs from 10KB minimum filter (company logos like Hubspot/Intel/DHL are 2-6KB; HeyGen capture: 13→75 assets) Note: adm-zip was NOT removed (reviewer #3) — it's still in packages/cli/package.json:30. The root package.json had patchright and purgecss removed, not adm-zip. Note: ANTHROPIC_API_KEY not restored in .env.example — grep confirms zero references in the entire codebase. The @anthropic-ai/sdk dependency was removed earlier in this branch. * refactor(capture): split index.ts (1175 to 566 lines) into modules Mechanical extraction, zero logic changes. New files: - mediaCapture.ts (345 lines): Lottie preview, video manifest/screenshots - contentExtractor.ts (314 lines): library detection, text, Gemini, asset descriptions - scaffolding.ts (135 lines): .env loading, project scaffold generation Also fixes false-positive BLOCKED.md with structural Cloudflare detection. Tested on 20 websites, pre/post output identical. * chore(capture): remove --split flow (splitter, verify, cssPurger, purgecss) The --split feature auto-generates compositions from captured HTML — a different approach from the /website-to-hyperframes skill workflow where agents build compositions from scratch using the storyboard. No skill file, no step reference, and no test session ever used --split. Removes 923 lines of unused code + purgecss dependency. Backed up to ~/Desktop/capture-split-backup/ for reference. * fix(security): add ssrf protection, lottie injection fix, oom guard - assetDownloader: add isPrivateUrl() guard blocking private IP ranges (127.x, 10.x, 172.16-31.x, 192.168.x, 169.254.x), cloud metadata endpoints, localhost, and non-HTTP schemes - mediaCapture: fix Lottie JSON injection by loading shell HTML first then passing animation data via parameterized page.evaluate() - index.ts: check Content-Length header before response.buffer() in Lottie network interception to avoid OOM on multi-GB responses * fix(capture): security fixes, timeout, sub-agent dispatch instructions Security (from miguel-heygen review): - assetDownloader: export isPrivateUrl() SSRF guard - htmlExtractor: add isPrivateUrl check before CSS fetch - mediaCapture: add isPrivateUrl check before Lottie fetch - mediaCapture: fix previewPage leak (try/finally) - mediaCapture: skip Lottie files > 2MB for preview (CDP limit) - contentExtractor: skip images > 4MB for Gemini captioning - index.ts: check Content-Length before response.buffer() (OOM guard) - snapshot.ts: register error handler before server.listen() Capture improvements: - Default timeout 30s to 120s (Shopify needs ~90s for Cloudflare) - step-6-build: sub-agent dispatch template with explicit rules: pass file PATHS not contents, use local fonts not Google Fonts, verify ../assets/ references after each beat * fix(capture): catalog before DOM mutation, networkidle2, faster Gemini Critical: asset cataloger now runs BEFORE extractHtml which converts img src to data URLs. Framer sites like heykuba.com went from 2 to 78 images. - networkidle2 instead of networkidle0 (unblocks SPAs with WebSockets) - Lazy-load wait: scroll to bottom, wait for img.complete - CSS background-image cataloging for Framer/Webflow - SVG naming: checks class, id, parent, inner text (not just aria-label) - Gemini batch 5->20, pause 12s->2s (paid tier: 2000 RPM, ~0.001/img) - maxOutputTokens 300->500, descriptions sorted captioned-first - Remove tsx fallback from step-1 (reviewer nit, published CLI has it) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Step 3: Write the Narration Script
Before writing, re-read DESIGN.md — specifically the Overview and Components sections. The script should reference real product features, real stats, and real components that the website highlights. Use exact numbers from extracted/visible-text.txt.
The script is the backbone. Everything downstream — scene durations, animation timing, beat pacing — comes from the narration. Write it before the storyboard.
Save as SCRIPT.md in the project directory.
Pacing
- 2.5 words per second is natural speaking pace
- 15s = ~37 words. 30s = ~75 words. 60s = ~150 words
- Leave room for pauses. Silence between sentences is a feature, not dead air
- The script should feel SHORTER than the video — visual breathing room matters
Tone
Write like a person, not a brochure:
- Use contractions: "it's", "you'll", "that's", "we've"
- Vary sentence length — short punchy phrases mixed with longer flowing ones
- Read it out loud. If it sounds robotic, rewrite it
- Avoid jargon unless the audience expects it
Number Pronunciation
Write what you want the voice to say. TTS reads literally.
| On the website | Write in script as |
|---|---|
| 135+ | more than one hundred thirty five |
| $1.9T | nearly two trillion dollars |
| 99.999% | ninety nine point nine percent |
| 200M+ | over two hundred million |
| 10x | ten times |
| API | A P I |
| stripe.com | stripe dot com |
The visual can show the exact figure while the voice rounds it.
Structure
For product videos from a website capture:
- Hook — what's surprising or impressive about this product? A bold claim, a provocative question, a contrast, or a striking number. This is the opening line. Vary the hook type — don't default to a stat every time.
- Story — what does the product do? Who uses it? Keep it concrete.
- Proof — stats, customer names, social proof. Real numbers from the website.
- CTA — what should the viewer do? "Start building at stripe dot com."
Not every video needs all four. A 15-second social ad might be Hook + Proof + CTA. A 60-second product tour uses all four with more Story.
The Opening Line
The most important sentence in the video. It must create tension, curiosity, or surprise in the first 3 seconds.
Patterns that work:
- A bold claim: "The financial infrastructure that powers the internet economy."
- A question that provokes: "What if your database could think?"
- A contrast: "Your AI agent already knows how to make videos. It just needs the right format."
- A number that shocks: "Nearly two trillion dollars." (Use sparingly — not every video should open with a stat.)
If the opening is generic ("Welcome to Stripe" / "Introducing our product"), start over.
Example
From a 62-second product launch video (team reference):
Your AI agent already knows how to make videos.
It just needs the right format.
This is Hyperframes. An open source framework. HTML in, video out.
A div is a keyframe. Data attributes are your timeline.
CSS is your look. G-Sap is your animation engine.
Anything a browser can render can be a frame in your video.
CSS animations. G-Sap. Lottie. Shaders. Three.js.
Drop in music, sound effects, footage — it all composes together.
No new framework for the agent to learn.
Just HTML.
The agent writes it. The renderer captures every frame as MP4.
It's deterministic. Identical outputs, every time.
Give your agent the CLI. Tell it what to make.
Watch it build.
Hyperframes. Go make something.
Note: ~140 words for 62 seconds — that's 2.3 words/sec, leaving room for pauses and visual breathing.
