Miguel Ángel a5c2636e8c fix(cli): never print "[object Object]" from validate/inspect errors (#1810) 
* fix(cli): use normalizeErrorMessage so validate/inspect never print "[object Object]"

The validate and inspect (layout) commands formatted thrown values with
`err instanceof Error ? err.message : String(err)`. When a browser/CDP/
Puppeteer protocol error or a structured page error reaches the formatter
as a plain object without a string `message`, `String(obj)` yields the
useless literal "[object Object]", hiding the real cause.

Route those paths through the existing shared `normalizeErrorMessage`
helper, which returns an Error's message, a string as-is, an object's
`.message` when present, or a compact JSON serialization otherwise (with
a key-list and String fallback for circular/opaque objects). Also fold
the duplicated local `errorMessage` helpers in batchRender and preview
into the same shared helper.

Covered by added assertions in errorMessage.test.ts for the no-message
object and Puppeteer-style protocol-error object cases.

* fix(cli): route remaining browser/process error sites through normalizeErrorMessage

The validate/inspect fix routed only those two commands through the shared
normalizeErrorMessage helper. The same err instanceof Error ? err.message :
String(err) pattern survived in the other commands that drive a headless
browser or an external process (ffmpeg, Docker, CDP) or surface a network
API error, so a thrown structured object without a string message would
still render as the useless literal [object Object].

Route those sites through the shared helper:
  snapshot.ts (the closest sibling to validate/inspect, same bug class),
  render.ts (Chrome launch + Docker build), capture/index.ts and
  commands/capture.ts (page-driven extraction), auth/browser.ts,
  browser/manager.ts (Puppeteer browser resolution), and the cloud/lambda
  paths (cloud/render.ts, cloudrun.ts, lambda/render-batch.ts,
  lambda/policies.ts, cloud/detectAspectRatio.ts) that surface API/network
  error objects.

Only the message-deriving expression changes; control flow and error
propagation are untouched. capture/index.ts keeps appending the stack for
real Errors and only routes the non-Error branch. Adds a helper test for a
structured CDP-style error object (code + nested data, no message).

ukimsanov 969d6a334b fix(cli): default capture output to ./capture/ (auto-suffix capture-2/, capture-3/ on re-run) 
`hyperframes capture <url>` (no -o) used to dump into `./captures/<hostname>/`,
which buries the project two levels deep and silently merges re-runs into the
previous dir — file-by-file, so leftover screenshots / assets from the prior
run stay mixed in and any later `glob` sees both.

Switch the default to `./capture/`. When it already exists, auto-suffix to
`./capture-2/`, `./capture-3/`, … (up to -99). Each capture is its own clean
directory — no crud, no friction, no clobber. The CLI prints a one-line note
when the suffix kicks in so the user sees which dir actually got written.
Explicit `-o <name>` is unaffected (still overwrite-tolerant).

ukimsanov f8d9f51245 fix(cli): restore hyperframes capture <url>; move video download to --video flag 
PR #1447 added `capture video` as a citty subCommand. citty's runCommand
(node_modules/.bun/citty@0.2.2/.../dist/index.mjs:209-227) treats any non-flag
positional as a subcommand-name attempt and throws E_UNKNOWN_COMMAND when it
doesn't match — there's no fallback to the parent's positional args, so
`hyperframes capture https://vercel.com` died with "Unknown command https://vercel.com".

Per James's suggestion, surface video-download as `capture --video <project>`
(a mode flag) instead of a subcommand. Citty has no issue with a positional
URL coexisting with flags. `video.ts` now exports `runVideoMode()` instead of
a `defineCommand` default export.

- `hyperframes capture <url>` works again
- `hyperframes capture --video <project> --index N` downloads video
- `hyperframes capture --video <project> --list` lists manifest
- `hyperframes capture --video <project> --video-url <url>` downloads by URL

ukimsanov 6a024a367b feat(cli): capture-video on-demand fetcher + capture pipeline robustness 
For the hyperframes.dev website-to-video flow. Real-AI-test runs against
heygen.com, huly.io, and heygen-showcase surfaced two gaps: (1) capture's
logo / asset-captioning signals missed modern React/Tailwind builds; and
(2) there was no CLI surface to pull the videos the manifest references.

New command:

  • `hyperframes capture-video <project>` — on-demand downloader for
    entries in capture/extracted/video-manifest.json. Capture writes the
    manifest + preview PNGs but skips the mp4s; this pulls one entry by
    `--index N` (matched against the entry's `index` field, NOT array
    offset — gaps are possible when a preview screenshot fails). SSRF-safe
    via safeFetch, 250 MB cap, content-type whitelist, race-free
    exclusive-create write. Layout-aware (handles both standalone capture
    and W2H project layouts).

Capture pipeline fixes:

  • Structural logo signals (assetCataloger + tokenExtractor): inBanner /
    inHomeLink / matchesTitleBrand. Class-substring alone caught 0/32 SVGs
    on heygen.com — modern builds don't put 'logo' / 'brand' in any
    className.

  • Content-hash SVG slugs (assetDownloader): `svg-<8char-sha1>.svg` —
    label-derived slugs mis-attributed partner-logo carousels
    (heygen-logo.svg actually contained Google, hubspot-logo.svg contained
    Trivago, etc.). Content-hash names are invariant by construction.

  • SVG → PNG rasterization before Gemini Vision (contentExtractor): the
    raw-SVG-as-text path was hallucinating wordmarks (VIVIENNE for HubSpot,
    'wrestling' for Workday). Adds polarity detection so a white-glyph SVG
    flattened to a blank PNG gets inverted before captioning. LOGO tag in
    asset-descriptions.md when structural signals fire (independent of
    Gemini key presence).

  • Double-escape \/ inside the page.evaluate template literal in
    assetCataloger + tokenExtractor: the original `/^https?:\/\/.../`
    collapsed to `/` mid-template and threw `Unexpected token ^`. Capture
    was 100% blocked on this until the escape was fixed.

  • `asset-descriptions.md` header branches on Gemini-key presence with
    an explicit 'Vision OFF — catalog-derived descriptions' warning.

New lint rule:

  • `lintMissingLocalAsset` (cli/utils/lintProject): scans <video> / <img>
    / <source> src for local files that don't exist in the project.
    Empirically the most common sub-agent mistake across multi-URL runs
    (~5+ per run). Uses `resolveExistingLocalAsset` so the existence check
    matches the bundler's notion of 'resolves'. Masks comment / style /
    script ranges before scanning so a literal `<img src=missing.png>`
    inside a tutorial comment isn't reported.

Tests: 17 new for capture-video (safeFilename decoding/sanitization,
VIDEO_CONTENT_TYPE_RE accept/reject, pickManifestEntry index-field lookup
with gaps, URL-mismatch + bad-index rejection, --index over --url
priority); 70 cases under lintProject.test.ts covering the new rule and
existing rules.

ukimsanovandClaude Opus 4.6 4e87f28cd9 fix: address PR #339 review — 7 issues 
1. Catalog failure safety: warn when catalog is empty or throws, so
   capture doesn't silently produce zero images
2. Dead path: extract-audio-data.py → skills/gsap/scripts/ (was
   skills/hyperframes/scripts/)
3. --json fonts compat: emit both `fonts` (string[]) and
   `fontsDetailed` (FontToken[]) to avoid breaking external consumers
4. Restore .cursorrules writing alongside AGENTS.md + CLAUDE.md
5. .gitignore: remove over-broad `projects/` and `videos/` entries,
   keep scoped `cursor-tests/` and `launch-video*/`
6. agentPromptGenerator: mark unused params as reserved with comments,
   remove _animations from buildPrompt
7. Cookie filter: threshold 20 → 8 chars to preserve footer copy like
   "© 2026 Stripe" (16 chars) and "Privacy & Terms" (15 chars)

ukimsanov 92a5ef419b feat(capture): improve capture quality + clean up CLAUDE.md 
Capture improvements:
- Font weights via document.fonts API + DOM sampling (variable font detection)
- Section background-image extraction (no more false #FFFFFF on hero photos)
- Detected libraries surfaced in CLAUDE.md brand summary
- Structured visible-text.txt with [tag] prefixes, cookie/nav noise filtered
- tokens.json cleaned: removed images/paragraphs/icons (duplicated elsewhere),
  filtered sections to heading-only, trimmed cssVariables to design-relevant
- Removed redundant scroll pass in htmlExtractor (2-5s faster per capture)
- Font cap at 20 families, Placeholder/Fallback fonts filtered

CLAUDE.md rewrite:
- Removed prescriptive tone ("use exact strings" → "rephrase freely")
- Removed fluff sections (How to Create, DESIGN.md warning, Example Prompts,
  Source Patterns)
- asset-descriptions.md promoted to first data row
- Removed assets-catalog.json from inventory

Skill fixes:
- Dead shader refs → point to packages/shader-transitions/README.md

Ular KimsanovandClaude Opus 4.6 87f4c77e2f feat: website capture pipeline + 7-step video production skill (#284) 
* 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")

- 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)

  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

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)
