James 7ed3d0485a feat(skills): scaffold remotion-to-hyperframes skill (1/7)
Adds the directory + SKILL.md frontmatter for a new skill that translates
Remotion (React) compositions to HyperFrames (HTML+GSAP). This is the
foundation PR; subsequent PRs in the stack add the eval harness, test
corpus, translation references, and finally the SKILL.md body.

The frontmatter description enumerates trigger phrases and explicit
out-of-scope cases (useState/useEffect, async metadata, @remotion/lambda)
so the skill bows out cleanly when a Remotion composition isn't a clean
translation target — those should use the runtime interop pattern from
PR #214 instead.

Validated with skill-creator's package_skill.py.

Mu-Tsun Tsai 9b72a87c17 fix(lint): remove root_composition_missing_data_duration (#490)
* fix(lint): remove root_composition_missing_data_duration

Lint cannot statically observe the runtime's true Infinity-emission
condition: it requires a finite GSAP timeline duration AND a finite
media/sub-comp window AND timeline > floor + 1, none of which are
visible to the static linter. The looping shapes that drive the
condition are already covered by `gsap_infinite_repeat` and
`gsap_repeat_ceil_overshoot` (both from #243), which point at the
real authoring mistake — flagging the missing duration separately
was a noisy proxy for the same signal.

Per #490 review discussion, deprecate the static rule and let those
two GSAP rules carry the pre-render coverage. If perfect precision
on `durationInFrames = Infinity` is needed, that belongs on the
runtime/render path where `shouldEmitNonDeterministicInf` is
actually known.

Add regression tests pinning the removal: a docs-compliant root
without `data-duration` no longer warns, and the canonical
loop-inflated shape now surfaces only via `gsap_infinite_repeat`
instead of two duplicate findings.

* docs(skills): update step-6 build checklist after rule removal

Drops the `root_composition_missing_data_duration` reference now that
the rule is gone. Keeps the authoring recommendation (and explains the
runtime Infinity case) but points authors at the GSAP rules that
actually carry the lint signal: `gsap_infinite_repeat` and
`gsap_repeat_ceil_overshoot`.

Alex Coulombe 924fd2f145 docs(step-6-build): sharpen Rule 2 — name from() seek-past-end reset as root cause
Per review feedback on PR #364: the 'hero vanishes' failure has two
mechanisms. Primary: second tween's immediateRender overwrites the first
at construction time. Secondary: tl.from() resets to its declared from-
state when seeked past timeline end, which the capture engine triggers.
Both are now named so the rule has precise rationale, not just a pattern
to avoid.

ukimsanovandClaude Opus 4.6 c81ef50e2f feat(shader-transitions): support any aspect ratio + update skill
Add dynamic resolution to shader transitions and update Skeleton A
to use shaders on vertical compositions.

shader-transitions changes:
- webgl.ts: read dimensions from params instead of hardcoded constants
- capture.ts: accept width/height for html2canvas
- hyper-shader.ts: read data-width/data-height from composition root

skill + docs changes:
- Skeleton A now has 1 shader at hero reveal (s3→s4 midpoint)
- Removed "no shaders on vertical" limitation from docs
- Updated claude-design.mdx known limitations section

ukimsanov ee7c6c3c24 refactor(claude-design-skill): template-first rewrite with bug fixes
Replace the rule-heavy Claude Design skill with a template-first
approach. Instead of teaching all rules from scratch (863 lines),
provide pre-valid skeletons where structural rules are embedded.
Claude Design fills in palette, content, and animations.

Key changes:
- Pre-valid HTML skeletons for social reel (vertical), launch teaser,
  product explainer, and cinematic title
- Mixed transitions: 2-3 shader transitions at key moments, rest
  hard cuts (matches professional video practice)
- autoAlpha toggles for non-anchor scenes (fixes invisible middle
  scenes caused by HyperShader's blanket opacity reset)
- Explicit first-anchor opacity fix (HyperShader browser mode never
  auto-shows the first anchor scene)
- No shaders on vertical (1080x1920) — WebGL canvas is hardcoded
  to 1920x1080 in webgl.ts
- Inline animation patterns (counter, stroke draw, stagger, float,
  bar chart, orbit, highlight sweep, safe CSS grain)
- Claude Design → Claude Code handoff workflow documented in
  README template and delivery step
- Troubleshooting table for black preview, invisible scenes, seeking
- Self-review checklist split: structural validity, brand accuracy,
  animation baseline
- Skill description updated per review feedback on PR #353 to
  disambiguate from the hyperframes skill on cross-surface routing

Bugs fixed by this rewrite (confirmed across demov4-1 through
demov4-6 and demov5-1 through demov5-5):
- First shader anchor invisible in every composition
- Non-anchor scenes killed by blanket querySelectorAll(".scene")
  opacity reset
- visibility toggles insufficient (opacity:0 persists after reset)
- Shaders on vertical compositions produce distorted transitions

Miguel Ángel 25d7a54330 docs: add Claude Design HyperFrames entry point (#353)
## Summary
- add a GitHub-hosted `claude-design-hyperframes` skill entry point that tells Claude Design to fetch the upstream HyperFrames skills tree
- add a dedicated Claude Design docs guide and link it from quickstart, prompting, and the README
- fix `@hyperframes/player` CDN docs to show a working ESM include and the explicit global-build fallback

## Verification
- `bunx oxfmt --check README.md docs/docs.json docs/guides/prompting.mdx docs/packages/player.mdx docs/quickstart.mdx packages/player/README.md docs/guides/claude-design.mdx skills/claude-design-hyperframes/SKILL.md`
- `bun run lint:skills`
- `bunx mintlify broken-links`
- browser-engine screenshots captured with Playwright CLI for the changed docs/source surfaces:
  - `/tmp/hyperframes-pr-artifacts/claude-design-guide-source.png`
  - `/tmp/hyperframes-pr-artifacts/player-docs-source.png`

## Notes
- `mintlify dev`, `mintlify validate`, and `mintlify export` stalled in this environment during preview/bootstrap, so I used the broken-links check plus screenshot-based browser fallback instead of claiming a full rendered-site pass.
- The GitHub entry-point setup reflects current Claude Design behavior discussed in the task: point Claude Design at the repo-hosted skill URL rather than a ZIP upload flow.

Alex Coulombe 731baebbaa docs(website-to-hyperframes): add load-bearing GSAP authoring rules
Add five animation-authoring rules to step-6-build.md that the linter
cannot catch but that silently ship broken output. Surfaced from two
independent builds (2026-04-20) where compositions passed lint and
still rendered elements invisible / unscrubbing.

Rules added:
- No iframes for captured content (don't scrub)
- Never stack transform tweens on one element (entrance + Ken Burns
  on same img silently kills it)
- Prefer tl.fromTo() over tl.from() inside .clip scenes
  (immediateRender interacts badly with scene boundaries)
- Ambient pulses must attach to seekable tl, not standalone gsap.to()
- Generalize the caption hard-kill rule to every scene-boundary exit

James Russo 4a55bc8673 feat(cli): add --lang and auto-infer phonemizer locale from voice prefix (#351)
* feat(cli): add --lang and auto-infer phonemizer locale from voice prefix

`hyperframes tts` was calling Kokoro's `model.create(text, voice=, speed=)`
with no language argument, so Kokoro's default phonemizer (en-us) was
applied regardless of the voice selected. Picking `ef_dora` or `jf_alpha`
and feeding it Spanish or Japanese text produced English-phonemized
output.

Closes #349.

- `manager.ts`: add `SUPPORTED_LANGS`, `inferLangFromVoiceId`, and
  `isSupportedLang`. Attach a `defaultLang` field to every bundled voice
  and expand the bundled list with `ef_dora`, `ff_siwis`, `jf_alpha`,
  `zf_xiaobei` so `--list` surfaces multilingual options.
- `synthesize.ts`: accept optional `lang: SupportedLang` in
  `SynthesizeOptions`, forward it to the Python worker as `argv[7]`.
  The worker introspects `Kokoro.create`'s signature and only passes
  `lang=` when the installed kokoro-onnx version supports it. Returned
  metadata now includes `lang` and `langApplied` so callers can detect
  silent no-ops. Bump the cached script filename to `synth-v2.py` so
  existing installs pick up the new script automatically.
- `commands/tts.ts`: add `--lang, -l` with validation against
  `SUPPORTED_LANGS`. Resolution order is explicit `--lang` > inferred
  from voice prefix > `en-us`. When explicit lang disagrees with the
  voice-implied lang (legitimate for stylized accents), emit a
  dim-level hint; suppress under `--json`. When kokoro-onnx silently
  ignores the kwarg, log that too. Update `--list` with a new
  "Lang code" column and add multilingual examples.
- Tests: new `manager.test.ts` covering every supported prefix, the
  unknown-prefix fallback, case-insensitivity, `isSupportedLang`
  validation, and a regression guard that every bundled voice has a
  valid `defaultLang` matching its ID.
- Docs: `docs/packages/cli.mdx` and `skills/hyperframes/references/tts.md`
  updated with the flag, examples, the espeak-ng dependency note for
  non-English phonemization, and the voice-prefix → lang table.

Backward compatibility:
- English voices (a*/b* prefixes) continue to phonemize as en-us / en-gb
  — no change.
- Non-English voices now phonemize correctly by default (bug fix, not a
  regression).
- Older kokoro-onnx versions that don't know the `lang` kwarg keep
  working via signature introspection; the CLI logs a dim note if
  `--lang` was requested but ignored.

Verification:
- `bun --cwd packages/cli test` — 128 tests pass (incl. 17 new).
- `bunx oxlint` and `bunx oxfmt --check` clean on changed files.
- `bun run build` succeeds.
- `npx tsx packages/cli/src/cli.ts tts --help` / `--list` render cleanly;
  invalid `--lang` produces a clean error with the valid-codes list.

* refactor(cli): simplify tts --lang implementation

Post-review cleanup on #351. Net -21 lines.

- Drop `defaultLang` field + `makeVoice()` helper from VoiceInfo —
  compute via `inferLangFromVoiceId(v.id)` at read time in listVoices.
  The only reader was the --list table; caching the derived value on
  every voice added a self-consistency invariant we had to test.
- Drop redundant `lang` field from SynthesizeResult — caller already
  knows the requested lang since it passed it in; only `langApplied`
  carries information the caller can't derive.
- Use `errorBox` for --lang validation to match the house style in
  render.ts (other validation errors already use errorBox).
- Reuse existing `langList` module constant in the validation error
  instead of re-joining SUPPORTED_LANGS.
- Inline `DEFAULT_LANG` — used once in inferLangFromVoiceId.
- Trim WHAT-restating comments and the duplicate prefix-enumeration
  JSDoc on inferLangFromVoiceId (VOICE_PREFIX_LANG already carries
  per-row comments).
- Clean up orphaned `synth*.py` files in ~/.cache/hyperframes/tts
  when writing the current versioned script, so repeated upgrades
  don't leak files.
- Drop the `EN-US` case-sensitive-rejection test assertion — the CLI
  lowercases input before validation, so accepting mixed case is a
  feature, not a bug.

Tests: 16/16 in `manager.test.ts`, 127/127 full CLI suite pass.
Lint + format + typecheck clean.

Ular KimsanovandClaude Opus 4.7 a78ec5ec76 fix(skill): all file paths use capture/ subfolder prefix (#345)
* fix(skill): all file paths use capture/ subfolder prefix

Step-1 was updated to capture into <project-dir>/capture/ but all
file-read instructions across steps 1-6 still used bare paths
(extracted/tokens.json, assets/hero.png). Agents following the skill
looked for files in wrong locations, producing broken compositions
with 404'd images and fonts.

- step-1: all 12+ file-read paths prefixed with capture/
- step-2: tokens.json and asset-descriptions.md paths fixed
- step-3: visible-text.txt path fixed
- step-4: asset-descriptions.md, asset examples, directory tree expanded
  to show capture/ children (screenshots/, assets/, extracted/)
- step-5: minor cleanup
- step-6: asset-descriptions.md path fixed, composition examples already
  correct (../capture/assets/)
- techniques.md: Lottie, video, font paths all prefixed

ukimsanovandClaude Opus 4.6 4e87f28cd9 fix: address PR #339 review — 7 issues
1. Catalog failure safety: warn when catalog is empty or throws, so

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

ukimsanov 517e327294 docs(skill): render step is on-demand, not automatic
Preview is the delivery — scrub through it, iterate on tweaks, only render
once the user explicitly asks ("render it", "make the final", "I'm happy").
Rendering takes minutes per pass and is wasted work if the user wants any
changes after seeing it.

- step-7-validate: rename Render section to "Render (on-demand only)" and
  make the trigger criteria explicit
- SKILL.md: step-7 summary updated to "Deliver the preview to the user
  first — only render to MP4 on explicit request"

ukimsanov 1a69cde4be docs(skill): shader/audio/render/snapshot guidance from regression evidence
Adds decision guidance and conventions the 8-site regression test exposed as
blind spots — agents had the capability but never reached for it.

step-1-capture:
- Clarify capture goes into <project-dir>/capture/ so capture artifacts stay
  isolated from later build files (SCRIPT/STORYBOARD/DESIGN/compositions/)
- 7/8 regression tests already did this; codify as the convention

step-4-storyboard:
- Add "When to pick which" decision table for shader vs CSS vs hard cut
  transitions. Shader transitions were available but used in 0/8 tests —
  every test defaulted to CSS. The table frames shaders as "reveals, reaction
  shots, brand moments" vs CSS as "connective tissue"
- Update technique count (10 → 11)

step-6-build:
- Mid-scene activity table gets a new row for audio-reactive logo/CTA
  animation (bass pulse, treble glow). Audio-reactive was used in 0/8 tests
  despite narration being present in all of them

step-7-validate:
- Snapshot section: explicit "use hyperframes snapshot, don't roll custom"
  with the default naming pattern spelled out. Stripe's run used custom
  ffmpeg naming (beat-6-cta-at-20.5s.png) instead of frame-XX-at-Ys.png
- New render section: require --output renders/<project>.mp4 so final MP4s
  have predictable names. Without this, 7/8 tests produced wildly different
  filenames (preview.mp4, cal_2026-04-19_20-29-21.mp4, basecamp.mp4, etc.)

techniques.md:
- New technique #11: Audio-Reactive Animation. Covers the sampling pattern
  (per-frame tl.call, not single tween), when to use (music/dramatic VO
  videos), intensity ranges (3-5% for text/logos, 10-30% for backgrounds),
  and anti-patterns (equalizer bars, waveforms, strobing). Cross-references
  skills/hyperframes/references/audio-reactive.md for the full API

ukimsanov d8f1af1ef1 feat(capture): write AGENTS.md alongside CLAUDE.md + skill refinements from regression tests
Capture pipeline:
- agentPromptGenerator now writes AGENTS.md + CLAUDE.md (drop legacy
  .cursorrules), matching the dual-file convention already used by the
  _shared templates in hyperframes init. AGENTS.md is picked up natively by
  Cursor, Codex, Gemini CLI, Windsurf, Aider, and Jules; CLAUDE.md covers
  Claude Code. Both files share the same content — a capture data inventory
  that points agents to the website-to-hyperframes skill.

website-to-hyperframes skill refinements (derived from 8-site regression test):
- Drop slash-command phrasing throughout SKILL.md and step-6-build.md so the
  skill works identically across Claude Code (slash), Cursor (auto-discover
  by description), and other agents.
- Remove stale HANDOFF.md references from SKILL.md step-7 summary and
  reference table — matches the intent of the prior step-7 cleanup.
- step-5-vo: specify narration.txt filename convention (pronunciation-
  substituted spoken text; distinct from SCRIPT.md the creative doc).
- step-6 self-review adds three rules derived from actual lint warnings
  observed across the 8 regression runs:
    - Every <template> root needs data-start + data-duration (catches
      root_composition_missing_data_start/duration, seen in 4/8 runs).
    - Caption exits need a hard tl.set kill after tl.to(opacity:0), or
      per-word karaoke tweens can leave captions stuck on screen
      (caption_exit_missing_hard_kill).
    - No duplicate media nodes with identical src + start + duration, or
      the compiler discovers them twice (duplicate_media_discovery_risk).

Housekeeping:
- .gitignore: add cursor-tests/, basecamp-video/, projects/, videos/ —
  local regression-test scratch dirs that should never be committed.
- Remove two broken symlinks from .claude/skills/ that pointed to paths
  which never existed in the repo (.claude/skills/ is already gitignored).

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 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

  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

- Fix asset descriptions: use CatalogedAsset.contexts/notes instead of
  nonexistent htmlContext field

* 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

* 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`.

* 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.

* 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)

Vance IngallsandClaude Opus 4.6 a262ad59f3 chore(skills): remove 1,685 lines of redundant skill content (#283)
* chore(skills): remove 1,685 lines of redundant and irrelevant skill content

- Remove 5 GSAP references irrelevant to HyperFrames (scrolltrigger,
  plugins, react, frameworks, utils) — no scroll, no frameworks, no
  interactive plugins in video compositions
- Remove shader-setup.md and shader-transitions.md — duplicated by
  @hyperframes/shader-transitions package (packages/shader-transitions/)
- Remove marker-highlight.md and examples.md — JS library docs superseded
  by css-patterns.md (deterministic, GSAP-driven, fully seekable)
- Trim CLAUDE.md to dev-only instructions — move product docs (transcription,
  TTS, player) to skills where they belong
- Deduplicate house-style.md typography/motion sections — point to
  dedicated references instead of repeating rules
- Clean up stale references to deleted files across SKILL.md and catalog.md
- Update gsap skill description to reflect HyperFrames-only scope

Skills: 5,230 → 3,714 lines (29% reduction)
CLAUDE.md: 204 → 50 lines (75% reduction)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(skills): update broken marker-highlight.md references in captions.md

Point to css-patterns.md instead of deleted marker-highlight.md.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(skills): update stale shader CSS rule to reference package API

BG_COLOR was from the old manual setup. Now it's bgColor in the
@hyperframes/shader-transitions init() config.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(skills): address 6 doc gaps surfaced by eval agents

P0: Document HyperShader as IIFE global name in shader-transitions README
P1: Replace async fetch() with sync XHR in effects.md audio data loading
    (fetch violates synchronous timeline construction rule in SKILL.md)
P1: Change <div> to <span> in css-patterns.md marker highlight patterns
    (<div> inside <p> is invalid HTML, breaks layout in inline contexts)
P2: Clarify bgColor as fallback color in shader-transitions README
P2: Add data-start to Composition Clips table in SKILL.md
    (root composition element needs data-start="0", linter enforces it)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(templates): update init templates to match trimmed skill scope

- Remove ScrollTrigger/plugins/React/Vue/Svelte from gsap skill description
- Replace class="clip" with accurate pattern examples in skill intro text
  (class="clip" is still in Key Rules where it belongs)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(skills): remove contradictory 5:1 contrast threshold from house-style

house-style.md said 5:1 minimum, but hyperframes validate enforces
WCAG AA (4.5:1 normal text, 3:1 large text). Now defers to validate
instead of stating a conflicting number.

James Russo acf8223171 fix(skills): correct README skills table and move orphaned scripts into hyperframes skill (#282)
## What

Fixes the README skills table to match actual skill names, and moves two orphaned script directories into the `hyperframes` skill where they belong.

## Why

**README**: Listed `hyperframes-compose` and `hyperframes-captions` as separate skills — these don't exist. Captions/compose are part of the `hyperframes` skill. Also listed `gsap-core, gsap-timeline, gsap-plugins, ...` but the actual skill is just `gsap`. Missing `hyperframes-cli` entirely.

**Orphaned scripts**: `skills/hyperframes-animation-map/` and `skills/hyperframes-contrast/` had scripts but no `SKILL.md` — they looked like broken skills and wouldn't be installed by `npx skills add`. They're helper scripts invoked by the main `hyperframes` skill (SKILL.md already references them in the "Quality Checks" section). Moving them under `skills/hyperframes/scripts/` makes them part of the skill they belong to.

## How

**README skills table** — corrected to match the 4 actual skills:
- `hyperframes` (was `hyperframes-compose` + `hyperframes-captions`)
- `hyperframes-cli` (was missing)
- `hyperframes-registry` (unchanged)
- `gsap` (was `gsap-core, gsap-timeline, gsap-plugins, ...`)

**Script moves:**
- `skills/hyperframes-animation-map/scripts/animation-map.mjs` → `skills/hyperframes/scripts/`
- `skills/hyperframes-contrast/scripts/contrast-report.mjs` → `skills/hyperframes/scripts/`
- Removed empty `skills/hyperframes-animation-map/` and `skills/hyperframes-contrast/`
- Updated path references in SKILL.md, both script headers, and `contrast-audit.browser.js`

## Test plan

- [ ] `grep -r "hyperframes-animation-map\|hyperframes-contrast" --include="*.md" --include="*.mjs" --include="*.js" --include="*.ts" .` returns no results
- [ ] `ls skills/` shows only `gsap`, `hyperframes`, `hyperframes-cli`, `hyperframes-registry`
- [ ] README skills table matches `skills/*/SKILL.md` names
- [x] Documentation updated (if applicable)

Miguel Ángel d3f2295d80 feat(skills): add contrast audit + animation map quality skills (#267)
## Summary

Two new quality skills + CLI integration that give agents feedback loops they currently lack — pixel-level contrast auditing and structured animation analysis.

### What this unlocks for agents

**Agents can now catch accessibility failures that humans and LLMs consistently miss.** The contrast audit runs automatically on every `hyperframes validate` and reports WCAG AA violations as warnings. In the eval, 4 out of 5 palettes had failing contrast — every baseline composition shipped broken, every treatment composition caught and fixed it.

**Agents can now reason about animation choreography.** The animation map produces a structured JSON report with:
- Per-tween natural language summaries ("card1 slides 23px up over 0.5s, fades in, ends at (120, 200)")
- ASCII timeline showing the full choreography as a Gantt chart
- Stagger detection with actual intervals ("3 elements stagger at 120ms" — validates against brief specs)
- Dead zone detection (periods >1s with no animation — missing entrance or intentional hold?)
- Element lifecycles (first/last animation, final visibility — catches elements that enter but never exit)
- Scene snapshots at 5 timestamps (what's on screen at any moment)

### Changes

**Skills (new)**
- \`skills/hyperframes-contrast/\` — WCAG contrast audit skill + script
- \`skills/hyperframes-animation-map/\` — animation analysis skill + script

**CLI**
- \`hyperframes validate\` now runs contrast audit by default (warnings, not errors)
- \`hyperframes validate --no-contrast\` to skip
- \`hyperframes render --html-only\` compiles HTML without video encoding
- Browser-side WCAG code in \`contrast-audit.browser.js\`, inlined at build time via esbuild text loader

**Producer**
- Exported \`compileForRender\` for the \`--html-only\` flag

### Eval results

5 prompts x 2 arms = 10 compositions. Arm A = baseline skills. Arm B = +contrast +animation-map.

| Prompt | Failing color | Before | After |
|--------|--------------|--------|-------|
| Halflife | Cement on Ink | 2.98:1 | 5.33:1 |
| Meridian | Ash on Midnight | 2.08:1 | 5.44:1 |
| Typesmith | Pencil on Paper | 3.19:1 | 5.50:1 |
| Lattice | Gray-600 on Terminal | 2.59:1 | 7.50:1 |

Animation map correctly enumerated 142 tweens across 5 compositions, detected stagger groups, flagged pacing issues, and produced scene snapshots.

### Dedicated evals

https://www.heygenverse.com/a/2cac956b-3d14-47bf-90e8-3c1f50e671f3

## Test plan

- [x] Eval: 10 compositions (5 baseline, 5 treatment), all rendered
- [x] Contrast audit caught 4/4 failing palettes, 0 missed
- [x] \`hyperframes validate\` shows contrast warnings by default (exit 0)
- [x] \`hyperframes validate --no-contrast\` skips audit
- [x] \`hyperframes validate --json\` includes contrast data
- [x] Animation map tested on 3 compositions (17, 27, 51 tweens)
- [x] Stagger detection, dead zones, snapshots, timeline all verified
- [x] \`bun run build\` passes
- [x] \`bun run lint\` passes (0 errors, 0 warnings, 0 skill lint issues)

James Russo 9943091247 feat(registry): seed transition blocks — 14 shader + 14 CSS showcase (#270)
## What

Add 28 transition blocks from the Hyperframe Template Structure catalog, bringing the registry to 53 total items.

### Shader transitions (14 blocks, WebGL, 4s each)
`domain-warp-dissolve`, `ridged-burn`, `whip-pan`, `sdf-iris`, `ripple-waves`, `gravitational-lens`, `cinematic-zoom`, `chromatic-radial-split`, `glitch`, `swirl-vortex`, `thermal-distortion`, `flash-through-white`, `cross-warp-morph`, `light-leak`

### CSS transition showcases (14 blocks, various durations)
`transitions-3d`, `transitions-blur`, `transitions-cover`, `transitions-destruction`, `transitions-dissolve`, `transitions-distortion`, `transitions-grid`, `transitions-light`, `transitions-mechanical`, `transitions-other`, `transitions-push`, `transitions-radial`, `transitions-scale`, `transitions-shader`

## Why

Phase D content accumulation. Transitions are the most-requested category for the catalog.

## How

- Shader transitions extracted from `shader-showcase.zip`, each a standalone HTML with WebGL shaders
- CSS transitions extracted from `showcase-bundle.zip`, each a standalone showcase page
- All tagged with `transition` + `shader` or `showcase` for catalog grouping
- Preview thumbnails generated for all 28 blocks
- Catalog pages + index regenerated

## Test plan

- [x] All 28 blocks produce preview thumbnails
- [x] `registry-item.json` validates for all blocks
- [x] Catalog pages generated (45 total items in catalog-index.json)
- [x] `oxfmt --check` passes

James Russo 4bde66f532 feat(skills): hyperframes-registry skill (#261)
## What

New skill `hyperframes-registry` that teaches AI coding agents how to install and wire registry blocks and components into HyperFrames compositions.

### Skill structure
```
skills/hyperframes-registry/
  SKILL.md                          — triggers, overview, quick reference
  references/
    install-locations.md            — default paths, hyperframes.json config
    wiring-blocks.md                — iframe inclusion, data attributes, positioning
    wiring-components.md            — snippet merging (HTML, CSS, JS, timeline)
    discovery.md                    — manifest reading, item fields, available items table
    demo-html-pattern.md            — why components ship demo.html, structure conventions
  examples/
    add-block.md                    — worked example: data-chart block install + wiring
    add-component.md                — worked example: shimmer-sweep component install + wiring
```

## Why

Phase B of the catalog plan (PR 10). Without this skill, agents using `hyperframes add` have to guess how to wire installed items into compositions. The skill encodes the iframe/snippet patterns so agents get it right on the first attempt.

## How

- SKILL.md frontmatter triggers on: `hyperframes add`, "block", "component", `hyperframes.json`
- References cover every step: discovery, install, wiring blocks (iframe), wiring components (snippet merge), and the demo.html convention
- Two worked examples walk through complete install-to-preview workflows
- Updated CLAUDE.md skills table + trigger rules, README.md skills table, docs/packages/cli.mdx

## Test plan

- [x] `scripts/lint-skills.ts` passes (checked 4 skill files, no issues)
- [x] `oxfmt --check` passes on all markdown files
- [x] SKILL.md frontmatter has valid `name` and `description`
- [x] All reference links in SKILL.md resolve to existing files
- [x] CLAUDE.md, README.md, and docs CLI page updated with new skill

James Russo 08fb1de61f feat(cli): add command + hyperframes.json (#256)
## What

PR 5/17 of the catalog system rollout. Adds the `hyperframes add` verb for installing blocks and components from the registry into an existing project, plus the `hyperframes.json` project config that tells `add` which registry to use and where to drop files. Stacks on #255.

- **`packages/cli/src/commands/add.ts`** — new `hyperframes add <name>` command. Resolves an item, validates target paths, installs files in parallel, builds an include snippet, copies it to the clipboard. Exposes a testable `runAdd(opts)` function; the citty default wraps it with console output + exit handling
- **`packages/cli/src/utils/projectConfig.ts`** — read/write/normalize `hyperframes.json`. Tolerant to missing and partial configs
- **`packages/cli/src/utils/clipboard.ts`** — minimal cross-platform clipboard (pbcopy / clip.exe / wl-copy / xclip / xsel). Zero deps. Gracefully no-ops in headless environments
- **`packages/cli/src/commands/init.ts`** — write `hyperframes.json` during scaffold if not already present
- **`packages/cli/src/cli.ts`** + **`help.ts`** — register `add` under Getting Started (directly below `init`)

Design doc: [Hyperframes Catalog System](https://www.notion.so/heygen/Hyperframes-Catalog-System-Design-Plan-341449792c69813f899dcd53b4c0383a).

## UX

```bash
# Scaffold a project (now writes hyperframes.json too)
npx hyperframes init my-video --example blank
cd my-video

# Add a block — files land, snippet copied to clipboard
npx hyperframes add claude-code-window
#  ✓ Added claude-code-window (hyperframes:block)
#    compositions/claude-code-window.html
#
#  Include snippet:
#    <iframe src="compositions/claude-code-window.html" data-start="0" data-duration="6"></iframe>
#
#  Copied to clipboard — paste into your host composition.

# Add a component effect
npx hyperframes add shader-wipe

# Headless / CI — no clipboard, JSON output for tooling
npx hyperframes add shader-wipe --no-clipboard --json
```

Running `hyperframes add warm-grain` (an example) errors clearly pointing to `init --example`.

## Docs (bundled in this PR per the tracker principle)

- `docs/packages/cli.mdx` — new `add` subsection under Commands (flags, examples, trigger rules) + new `hyperframes.json` section describing the config file shape

## Tests

- **`packages/cli/src/commands/add.test.ts`** — 11 tests:
  - `remapTarget` / `buildSnippet` pure helpers (5 tests)
  - `runAdd` integration against a mocked `fetch` registry: block install lands files + returns snippet, component install respects `paths.components` remap, example-typed names throw `AddError` with code `example-type`, unknown names throw `AddError` with code `unknown-item` (4 tests plus 2 covering block default path and non-default path preservation)
- **`packages/cli/src/utils/projectConfig.test.ts`** — 9 tests:
  - Write/read round-trip, partial-config normalization, corrupt-file handling, absent-file fallback to defaults, custom paths preserved
- **CLI suite:** 92 passed (was 72 on #255, **+20**). Same 4 pre-existing failures unchanged

## Scope decisions

- **`init.ts` full port to new resolver deferred.** The original plan bundled a removal of the `packages/cli/src/templates/` compat shim. That's ~300 more lines and isn't required for `add` to work. The compat shim from #254 still functions; a separate cleanup PR handles it
- **No ajv runtime schema validation.** Manifests are trusted as schema-valid. Full validation lands when third-party registries arrive (PR 14/15). Path safety is still enforced by the installer's `assertSafeTarget` guard
- **Default project paths stay under `compositions/`.** Blocks → `compositions/<name>.html`; components → `compositions/components/<name>/<file>`. Users override via `hyperframes.json#paths`

## Breaking / migration

**None.** Pure additive — new command, new file types, no existing commands or flags change. `init.ts` now writes `hyperframes.json` but that's a new additional file, not a modification of existing output.

## Stacks on

#255 — base branch. When #255 merges, this rebases onto `main`.

## Next in stack

PR 6 — `feat(registry): seed block — claude-code-window`. First real registry item. Exercises the full `hyperframes add <name>` flow end-to-end against a committed item on `main`.

Vance Ingalls cb3d94c2a5 feat: add @hyperframes/shader-transitions package (#251)
## Summary

New `@hyperframes/shader-transitions` package that encapsulates WebGL shader transitions into a single `HyperShader.init()` call. Replaces ~200 lines of per-composition boilerplate that LLMs failed to wire correctly 60% of the time.

### API

```js
var tl = HyperShader.init({
  bgColor: "#0a0a1a",
  accentColor: "#6366f1",
  scenes: ["scene1", "scene2", "scene3", "scene4", "scene5"],
  transitions: [
    { time: 7.2, shader: "cross-warp-morph", duration: 0.7 },
    { time: 15.2, shader: "domain-warp", duration: 0.7 },
  ]
});
tl.from("#s1-title", { y: 50, opacity: 0, duration: 0.7 }, 0.3);
```

### What the library handles

- **13 shader programs**: domain-warp, ridged-burn, whip-pan, sdf-iris, ripple-waves, gravitational-lens, cinematic-zoom, chromatic-split, glitch, swirl-vortex, thermal-distortion, cross-warp-morph, light-leak
- **html2canvas** bundled as dependency (not CDN) — single script tag for CLI users
- **DOM-during-holds**: canvas hidden between transitions, GSAP animations play on live DOM
- **Async capture with pause/resume**: timeline pauses during capture, resumes after textures uploaded — prevents progress tween from running ahead
- **Accent color theming**: `accentColor` derives dark/mid/bright uniforms. Burns, glows, leaks match the composition palette
- **Graceful degradation**: falls back silently when WebGL unavailable

### Code quality (from 3 review agents)

- No `!` non-null assertions — all WebGL creation calls throw on failure
- Vertex shader compiled once, cached across all programs
- Uniform/attribute locations cached per program via WeakMap (not looked up every frame)
- Captured canvases freed after texture upload (8MB each)
- Single timeline creation (was creating two, discarding one)
- Shared `tickShader()` render callback (was copy-pasted)
- `.finally()` for DOM restore in capture (was duplicated in `.then`/`.catch`)
- `parseHex` validates input (was silently producing NaN on invalid hex)
- Dead `ND`/`CP` shader library exports removed

### Shader-compatible CSS rules (transitions.md)

6 rules for compositions using shader transitions:
1. No `transparent` in gradients (canvas interpolates through black)
2. No gradient backgrounds on elements < 4px
3. No CSS variables on captured elements
4. `data-no-capture` for uncapturable decoratives
5. No gradient opacity < 0.15
6. Every `.scene` must have explicit `background-color` matching `bgColor`

### Build output

- IIFE (~214KB with html2canvas bundled, ~65KB gzipped) — `window.HyperShader`
- ESM + CJS + TypeScript declarations
- tsup build following `@hyperframes/player` conventions

## Test plan
- [ ] `bun run build` succeeds (includes shader-transitions)
- [ ] `bunx oxlint packages/shader-transitions/src/` — 0 errors
- [ ] Create a composition using `HyperShader.init()` — verify transitions fire, DOM animations play, accent colors match
- [ ] Test graceful degradation: composition works without WebGL (no transitions, no crash)
- [ ] Verify pause/resume: scrub to transition boundary — no jump in progress

Vance Ingalls 5de2af5bde feat(skills): improve hyperframes composition quality rules (#250)
## Summary

Overhaul the hyperframes composition skill based on 26 eval rounds (~100 generated compositions). The goal: prevent known AI design tells and composition bugs while giving the LLM maximum creative freedom.

### Typography (`fonts.md` → `typography.md`)
- Two-tier banned font list (32 fonts): tier 1 bans training-data defaults, tier 2 bans the reflex replacements
- Font discovery script: queries Google Fonts API, 5 dynamic categories, top 5 randomized per run
- Selection philosophy: register-first thinking, cross-check assumptions

### Google Fonts on-demand (`deterministicFonts.ts`)
- Any Google Font works without pre-bundling — compiler fetches woff2 at compile time
- Cached to `~/.cache/hyperframes/fonts/<slug>/<weight>-<style>.woff2`
- Parallel woff2 fetches via `Promise.allSettled` (was sequential)
- Single `mkdirSync({ recursive: true })` per family (was `existsSync` x11)
- Skip redundant `readFileSync` when buffer is already in memory from fetch

### Layout rules (`SKILL.md`)
- Flexbox with gap for content text — prevents overlap from absolute positioning
- `position: absolute` reserved for decoratives only
- Cards/containers explicitly banned

### Background layer (`house-style.md`)
- 3-5 persistent decorative elements per scene (glows, ghost text, accent lines)
- All decoratives MUST have ambient GSAP animation — static decoratives banned
- WRONG/RIGHT code examples

### Transition rules (`SKILL.md`)
- Always use transitions, always entrance animations, exit animations banned except final scene
- WRONG/RIGHT code examples showing banned exit patterns

### Other
- Flash cut transition removed
- CLAUDE.md: `bun install` / `bun run build` / `bun run test` (was pnpm)
- house-style.md trimmed from 184 to ~80 lines
- SKILL.md trimmed from 364 to ~230 lines

## Test plan
- [ ] `bun install` succeeds, workspace links resolve
- [ ] `bun run build` succeeds
- [ ] `npx hyperframes lint` passes on existing compositions
- [ ] Generate a composition with `/hyperframes` skill — verify flexbox, background decoratives with animation, entrance-only animations, no banned fonts
- [ ] Verify Google Fonts on-demand: use a non-bundled font, run `npx hyperframes preview`

Vance IngallsandClaude Opus 4.6 4c5b8e38a1 feat(skills): add typography and motion principles, fix validate $& bug (#228)
Add two new skill reference files that address measured LLM composition failures:

- fonts.md: Typography principles — banned fonts, guardrails for violations
  (pairing two sans-serifs, defaulting to 400/700 weight), and guidance the LLM
  genuinely doesn't apply without being told (register switching, tension as
  meaning, easing direction as emotion). Includes Google Fonts API discovery
  script with 7-category multi-strategy query.

- motion-principles.md: Motion design principles — guardrails for same-ease and
  same-speed defaults, y-axis entrance monotony, and guidance for build/breathe/
  resolve scene structure, hard cuts as intentional transitions, visual
  composition rules for video-not-web density.

Both files validated against baseline evals: 3 compositions created without
guidance confirmed the LLM reaches for banned fonts (Inter, Cormorant Garamond,
Playfair Display, Roboto Condensed), uses power2.out on 45-72% of tweens,
enters 80%+ of elements from y-axis, and pairs multiple sans-serifs.

Also:
- Fix validate.ts $& replacement bug (runtime source containing $& caused
  String.prototype.replace to re-insert the matched <script src=""> tag)
- Clean up font loading guidance across skills (compiler embeds automatically)
- Update house-style.md to reference fonts.md

Miguel Ángel 883bd8273e fix(skills): add rendering guardrails to hyperframes skill (#217)
## Summary

Adds critical rendering constraints to the `hyperframes` skill discovered from eval analysis of 27 agent-generated compositions. These guardrails prevent agents from producing compositions that technically work but render poorly.

## What it fixes

| Rule Added | Eval Prompts Affected | Issue |
| --- | --- | --- |
| Ban `repeat: -1` | #20 loading-spinner (2.0/5) | Infinite timeline broke capture engine |
| Ban async timeline construction | #16 particle-logo (2.6/5) | Timeline empty at capture time |
| Min font size 16px (labels), 20px (body) | #7, #8, #13, #14, #15, #19 | Illegible text after encoding |
| Ban full-screen dark linear gradients | #3, #5, #10, #14 | H.264 color banding |
| `<link>` fonts over CSS `@import` | #7, #24 | Font loading race conditions |

## Changes

- **Rules section**: Added `repeat: -1` ban, async timeline ban, items 8-9 to "Never do" list
- **Typography section**: Expanded font size guidance with specific minimums per text role (headlines, body, labels)
- **New "Backgrounds and Color" section**: Guidance on avoiding gradient banding
- **Output Checklist**: 5 new items covering all new constraints

## Test plan

- [ ] Run eval with updated skill and compare avg quality scores
- [x] Skill renders correctly in `/hyperframes` invocation

Vance IngallsandClaude Opus 4.6 569513145b feat(skills): add WebGL shader transitions and restructure catalog (#213)
* feat(skills): add WebGL shader transitions and restructure catalog

Add 14 WebGL fragment shader transitions to the transitions skill:
domain warp dissolve, ridged burn, whip pan, SDF iris, ripple waves,
gravitational lens, cinematic zoom, chromatic radial split, glitch,
swirl vortex, thermal distortion, flash through white, cross-warp
morph, and light leak (shader).

Restructure catalog.md from a 1045-line monolith into a 105-line
routing layer with 15 reference files. SKILL.md loads at 101 lines,
catalog.md loads at 105 lines — reference files loaded on demand
only for the transition type being implemented.

Key additions:
- Full WebGL setup boilerplate with media capture (images, video,
  object-fit: cover, live video re-upload during transitions)
- Hard rules for shader transitions capturing all bugs found during
  development (Y-flip, preserveDrawingBuffer, fwidth, boomerang,
  tween proxy reuse, tl.call vs onComplete)
- CSS vs Shader decision guide in SKILL.md
- Visual pattern warning against repeating geometric patterns
- Shader transitions slotted into mood/energy mapping tables
- Noise libraries: quintic C2, ridged, erosion FBM, cosine palette

* refactor(skills): fold transitions into hyperframes skill

Move transitions from a standalone skill (4th top-level) into
hyperframes/references/transitions/, aligning with the consolidation
in #211 that reduced 15 skills to 3. Fewer standalone skills means
higher trigger reliability for multi-skill tasks.

Also removes stale text-burn-dom.html reference from css-destruction.md.

James RussoandClaude Opus 4.6 0a0d5d3654 refactor(skills): consolidate 15 skills into 3 (#211)
* refactor(skills): consolidate 15 skills into 3 for better trigger reliability

Merge 9 GSAP skills (core, timeline, scrolltrigger, plugins, utils, react,
frameworks, performance, effects) and 6 HyperFrames skills (compose, captions,
tts, audio-reactive, marker-highlight, cli) into 3 consolidated skills:

- `gsap` — core API + timelines + performance in SKILL.md; scrolltrigger,
  plugins, utils, react, frameworks, effects in references/
- `hyperframes` — composition authoring rules in SKILL.md; captions, tts,
  audio-reactive, marker-highlight in references/
- `hyperframes-cli` — CLI commands (init, lint, preview, render, etc.)

Why: With 15 separate skills, agents must correctly trigger the right subset
for any task. "Create an animated video with captions" needed 6+ skills to
fire — each with ~90% trigger accuracy means ~53% chance of getting all of
them. With 3 skills, that same task needs just `hyperframes` + `gsap` (~90%
both fire). Progressive disclosure still works via references/ files loaded
on demand.

Also fixes: CLAUDE.md referenced `window.__GSAP_TIMELINE` (incorrect) —
corrected to `window.__timelines`.

- captions: fix overflow to `visible` (not hidden — clips glow effects),
  add container pattern warning, scale headroom formula, and self-lint
  placement guidance
- audio-reactive: restore sampling frequency pattern (per-frame tl.call
  loop vs single tween) and textShadow-on-container gotcha
- effects/typewriter: restore word rotation, appending words, spacing
  with static text, and multi-line cursor handoff patterns
- effects/audio-visualizer: restore spatial mapping conventions, fetch vs
  inline loading, WebGL/DOM rendering approaches, and canvas layering
- hyperframes-cli: restore --strict-all flag in render flags table

Vance IngallsandClaude Opus 4.6 c47e710ffc feat(skills): add scene transitions skill with 35-type catalog (#212)
## What

A scene transition selection framework and implementation catalog covering 35 transition types across 8 categories.

### transitions skill

**SKILL.md** — Selection framework:
- Energy → transition mapping (calm/medium/high)
- Mood → transition mapping (warm, cold, editorial, tech, edgy, playful, dramatic, premium, retro)
- Narrative position guidance (opening, between sections, climax, outro)
- Blur intensity scaling by energy level
- Configuration presets (snappy, smooth, gentle, dramatic, instant, luxe)

**catalog.md** — Implementation reference:
- GSAP code for all 35 transitions
- Hard rules from real bugs (scene visibility, iframe compatibility, VHS clone pattern, z-index, overlay sizing)
- Scene template

### Categories

| Category | Transitions |
|----------|------------|
| Content-transforming | Push slide, vertical push, elastic push, squeeze, zoom through, zoom out, gravity drop, 3D flip |
| Reveal/mask | Circle iris, diamond iris, diagonal split, clock wipe, shutter |
| Dissolve | Crossfade, blur crossfade, focus pull, color dip |
| Cover | Staggered blocks, horizontal blinds, vertical blinds |
| Light | Light leak, overexposure burn, film burn |
| Distortion | Glitch, chromatic aberration, ripple, VHS tape |
| Pattern | Grid dissolve |
| Instant | Flash cut, morph circle |

## Why

Agents building multi-scene compositions were using the same opacity crossfade for every scene change regardless of video mood/energy. The transitions skill provides context-aware selection so a wellness video gets blur crossfades while a sports promo gets flash cuts and a cyberpunk event gets VHS distortion.

## How

- SKILL.md follows writing-skills guide: description uses "Use when..." triggers, no workflow summary, under 500 words
- catalog.md is heavy reference with table of contents
- Hard rules consolidated from real rendering bugs discovered during 16 A/B eval comparisons
- Mood mappings designed from a motion design perspective

## Test plan

- [x] 16 A/B eval compositions comparing with/without skill across moods
- [x] 39-scene transition catalog composition demoing every type
- [x] Skill audit against writing-skills guide
- [x] All transition types mapped to at least one mood
- [x] Lint passes

Vance Ingalls d8bffd41f9 feat(lint,skills): add caption/audio-reactive lint rules and skill guidance (#207)
## What

Bumped all package versions to `0.2.2-alpha.4` and added five new lint rules for caption and GSAP animation quality checks.

## Why

The new lint rules address common issues in HyperFrames compositions:
- Caption overflow clipping when emphasis words are scaled above 1.0x
- Text shadow artifacts on caption group containers with semi-transparent children
- Mismatch between fitText maxWidth and scaled word dimensions
- Imperceptible audio reactivity from single tweens instead of time-sampled animations
- Scene layer visibility conflicts when relying only on opacity tweens

## How

Added three new caption-specific lint rules in `captions.ts`:
- `caption_overflow_clips_scaled_words` - detects `overflow: hidden` on caption containers when scripts scale words above 1.0x
- `caption_textshadow_on_group_container` - flags textShadow tweens applied to group containers instead of individual words
- `caption_fittext_scale_mismatch` - calculates effective width from fitText maxWidth × max scale factor and warns when it exceeds safe bounds

Added two new GSAP lint rules in `gsap.ts`:
- `audio_reactive_single_tween_per_group` - identifies audio-reactive captions using peak values instead of time-sampled loops
- `scene_layer_missing_visibility_kill` - detects multi-scene compositions missing hard visibility kills after opacity exit tweens

Enhanced documentation with new mask reveals guide and updated existing skills with overflow handling, scene management, and audio reactivity best practices.

## Test plan

- [x] Lint rules tested against existing composition patterns
- [x] Documentation updated with new techniques and constraints
- [x] Version bumps applied consistently across all packages

* feat(cli): add `tts` command for local text-to-speech via Kokoro-82M

Adds `hyperframes tts` — generate speech audio locally using Kokoro-82M
(ONNX), no API key needed. Mirrors the transcribe command architecture.

- New command: `hyperframes tts "text" --voice af_heart --output speech.wav`
- 54 voices across 8 languages, ~5x realtime on CPU
- Auto-downloads model (~311 MB) + voices (~27 MB) to ~/.cache/hyperframes/tts/
- Requires Python 3.8+ with kokoro-onnx installed
- Extracted shared `downloadFile` utility from whisper/manager.ts with
  atomic .tmp→rename to prevent partial download corruption
- Added hyperframes-tts skill with voice selection guide
- Updated CLAUDE.md with TTS docs, voice table, and skill reference

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* docs(tts): improve skill per skill-creator guidelines

- Move trigger info from body to frontmatter description
- Remove `trigger` field (not a valid frontmatter field)
- Remove CLI flag docs Claude can derive from --help
- Remove redundant voice tables (keep content-to-voice mapping)

Vance Ingalls cb0b17062a feat(skills): add marker-highlight skill for animated text highlighting (#190)
## Summary

- **New skill:** **`marker-highlight`** — integrates [MarkerHighlight.js](https://github.com/Robincodes-Sandbox/marker-highlight) into HyperFrames compositions. Canvas-based animated text highlighting with 5 drawing modes: marker pen, circle, burst, scribble, and sketchout.
- **Studio fix:** added missing `captionSync` to useEffect dependency array (oxlint exhaustive-deps)
- **Studio fix:** `loadOverrides` now checks `res.ok` before parsing, preventing 404 console noise on projects without captions

## Skill details

The skill documents the non-obvious GSAP integration pattern discovered during development:

1. **One highlighter per container** — the library clears ALL `.highlight` divs from the shared parent on init, so multiple instances on sibling marks conflict
2. **`data-color`** **\+** **`data-original-bgcolor`** — prevents the CSS background-color flash that occurs when the library reads and clears the mark's background
3. **Canvas pre-draw + clear + reanimate** — `animate: false` pre-draws statically, canvases are hidden, then cleared and shown with `reanimateMark()` at trigger time for clean animated reveals
4. **`onReverseComplete`** **for rewind** — hides highlight divs when the timeline seeks backward past the trigger point

## Test plan

- [ ] `npx hyperframes lint` passes on test-composition
- [ ] Studio preview shows marker highlight on "something" at 1s, circle on "love" at 2.2s
- [ ] Rewind past trigger points hides highlights
- [ ] No 404 console errors for caption-overrides.json on non-caption projects

- docs(parser): add comment explaining the lazy ];  regex assumption

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(studio): address remaining caption designer feedback

Overlay: handle both per-word spans (generator output) and grouped text
nodes (existing templates). Wraps text nodes into individual spans on
demand so the overlay can target words in any caption format.

Property panel: add Typography (font, size, weight, spacing) and Color
(color, active, dim, opacity) sections alongside existing Position and
Transform controls.

Timeline: move caption timeline into a dedicated flex-shrink-0 section
below the main timeline tracks instead of inside the scrollable area.
Gives it fixed 60px height that's always visible.

Caption overrides: classify color tweens by comparing target color to
the dim baseline instead of relying on timeline position order. This
handles compositions with custom color tweens correctly.

App.tsx: remove polling interval, rely on runtime postMessage events
for caption detection. Add clarifying comment on why useEffect is
appropriate (external event subscription).

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(studio): restore cssScale in overlay coordinate conversion

getBoundingClientRect() on iframe-internal elements returns coordinates
in the iframe's native resolution (1920x1080), not the CSS-scaled
display size. The cssScale multiplier is needed to convert to parent
window coordinates. The earlier removal was incorrect — it only worked
at 1:1 scale.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(studio): fix reversed scaling on left-side corner handles

Scale interaction used horizontal dx from start position, which goes
negative when dragging left handles outward. Now uses distance from box
center — dragging away from center increases scale regardless of which
corner handle is used.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(studio): make rotation respond to horizontal drag only

Rotation handle sits directly above the word, so atan2-based rotation
barely responds to left/right movement. Replace with linear horizontal
mapping: drag right = clockwise, drag left = counter-clockwise,
200px = 90 degrees. Vertical movement is ignored.

Vance Ingalls d36c1785b9 feat(captions): energy-based technique selection and mandatory quality checks (#176)
## Summary

- Rewrite script-to-style mapping as an energy detection table (high → low) with mandatory animation requirements: karaoke baseline, 2+ highlight techniques, kinetic exits
- Replace `tl.call()` per-frame audio-reactive pattern with group-level GSAP tweens — read peak bass/treble for each group's time range and modulate entrance intensity at build time, no per-frame callbacks needed
- Add transcript quality check with automatic retry rules (>20% music tokens = retry with larger model)
- Add caption word structure lint rule (`.caption-group` + `<span>`) for studio editor compatibility
- Add multilingual model guidance and decision tree for model selection

## Test plan

- [ ] Skill files render correctly as markdown
- [ ] Cross-references between SKILL.md, dynamic-techniques.md, and transcript-guide.md resolve correctly
- [ ] `dynamic-techniques.md` audio-reactive section uses `tl.to()`/`tl.set()` only, no `tl.call()` loops

- Split install logic into global vs project-level
- Fix lint false positive: timed tags with `data-composition-id` no longer flagged by media rule

**Skill system cleanup (folded from #189):**
- Delete `install-skills.ts` (~485 lines) — remove custom installation wrapper entirely
- Strip skill logic from `init` — no more project-level `.claude/skills/` copies, no `--skip-skills` flag; replaced with post-scaffold message: `npx skills add heygen-com/hyperframes`

- Interpolate zero-duration word clusters for reliable karaoke timing

**Captions skill updates (folded from #176):**
- Rewrite script-to-style mapping as an energy detection table (high → low) with mandatory animation requirements: karaoke baseline, 2+ highlight techniques, kinetic exits
- Replace `tl.call()` per-frame audio-reactive pattern with group-level GSAP tweens — read peak bass/treble for each group's time range and modulate entrance intensity at build time
- Add transcript quality check with automatic retry rules (>20% music tokens = retry with larger model)
- Add caption word structure lint rule (`.caption-group` + `<span>`) for studio editor compatibility

**Multilingual defaults (folded from #186):**
- Default whisper model changed from `small.en` to `small` to prevent silent translation of non-English audio
- Added non-negotiable language rule to captions skill

## Test plan

- [ ] `pnpm test` passes (contraction merging, fragment merging, zero-duration interpolation, speech onset)
- [ ] Transcribe non-English audio — verify it transcribes in original language, not translates
- [ ] Skill files render correctly, cross-references resolve
- [ ] `dynamic-techniques.md` audio-reactive section uses `tl.to()`/`tl.set()` only, no `tl.call()` loops

Vance Ingalls 159a2e7113 feat(skills): add dynamic caption techniques and split captions skill into references (#173)
## Summary

- Split the captions skill from a single 611-line file into focused references: `SKILL.md` (core rules), `transcript-guide.md` (whisper/transcription), `dynamic-techniques.md` (animation patterns)
- Add `audio-reactive` skill with "Content, Not Medium" constraint — steers away from generic visualizations (equalizer bars, spectrum analyzers, waveforms) toward content-grounded animation where audio drives *when* and *how much*, not *what to show*
- Add initial dynamic caption technique selection by energy level

## Test plan

- [ ] All skill files render correctly as markdown
- [ ] Cross-references between files use correct relative paths
- [ ] `audio-reactive/SKILL.md` contains the anti-pattern list and content-grounded examples

Vance IngallsandClaude Opus 4.6 116e6aa8e0 feat(skills): add audio visualizer effect with extraction script (#168)
* feat(skills): add audio visualizer effect with extraction script

Adds reactive audio visualization patterns for HyperFrames:

Script: extract-audio-data.py pre-extracts per-frame RMS amplitude and
frequency band data via ffmpeg. Uses a 4096-sample FFT window for clean
frequency resolution and per-band normalization across the full track
so treble activity is visible alongside louder bass.

Patterns: spectrum bars, mirrored waveform, pulsing circle, circular
visualizer, background glow — all Canvas 2D driven from the GSAP
timeline via tl.call() at each frame.

Includes smoothing helper, band count guide, band ordering rules
(horizontal: low-left high-right), and combining patterns section.

* refactor(skills): replace prescriptive examples with data model + motion principles

Removes five hardcoded draw functions that would get copy-pasted verbatim.
Replaces with:
- Clear data model docs (what rms and bands mean, how to index)
- Rendering approach setup for Canvas 2D, WebGL/Three.js, and DOM
- Motion principles (smoothing, value mapping, what makes it feel good)
- Spatial mapping conventions (low-left/high-right, etc)

The LLM invents the visualization; the skill teaches the data contract
and motion constraints.

* fix(skills): off-by-one in band slicing, add data loading, fix trigger

- Fix exclusive slice end: high_bin clamped to n_bins (not n_bins-1)
  so the last FFT bin in each band is included
- Add data loading section to skill doc (inline and fetch patterns)
- Fix example JSON to show frame 0 at time 0.0
- Update description to trigger when audio is analyzed and music detected

* refactor(skills): require numpy, fix bugs, clean up skill doc

Script rewrite:
- numpy is now required (pure-Python DFT was unusable for real files)
- Use np.frombuffer instead of struct.unpack (~10x less memory)
- Precompute Hann window and band edges (were recalculated every frame)
- Extract SAMPLE_RATE as module-level constant
- Clamp band bins to prevent max() on empty slice
- Validate --fps and --bands inputs

Skill doc fixes:
- Fix fetch loading example (was null ref on sync for-loop)
- Remove redundant Canvas 2D section (was duplicate of Step 3)
- Fix opening line (said "Canvas 2D" but doc covers 3 approaches)
- Fix undefined W/H in example

Vance IngallsandClaude Opus 4.6 e7283e5ce3 feat(skills): add gsap-effects skill with typewriter pattern (#158)
* feat(skills): add gsap-effects skill with typewriter pattern

Distills typewriter text animation into a reusable reference:
basic typewriter, blinking cursor, word rotation, appending words,
and a characters-per-second timing guide. Uses GSAP TextPlugin.

Also references the new skill from compose-video.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(skills): emphasize cursor must always blink when idle and sit flush

Two key rules added to the typewriter skill:
1. Cursor must blink in every idle state (after typing, after clearing,
   during hold pauses) — a solid idle cursor looks broken.
2. No whitespace between text and cursor elements in HTML — any gap
   between the last character and the caret looks wrong.

Also adds cursor-hide state for multi-line handoffs and updates word
rotation example to include cursor state management.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(skills): backspace must delete from end, not front

TextPlugin's text:{value:""} removes characters from the front,
which looks wrong. Added a backspace helper that steps through
substrings from right to left using tl.call(). Updated word
rotation example to use it.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(skills): handoffs must blink before typing, use margin for spacing

Two lessons from testing:
1. Cursor handoffs need a blink pause — going hide→solid directly
   skips the idle state. Pattern: hide→blink→pause→solid→type→blink.
2. Use margin-left on a wrapper span for spacing between static and
   dynamic text. Flex gap spaces the cursor away, trailing spaces
   collapse.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(skills): enforce single visible cursor as a hard rule

Only one cursor may be visible at a time. Multiple cursors on
screen looks broken. Every other cursor must be cursor-hide.
Promoted to rule #1 in the cursor section.

Vance IngallsandClaude Opus 4.6 9cbfec1eca feat(skills): add hyperframes-cli skill (#154)
* feat(skills): add hyperframes-cli skill for CLI workflow guidance

Adds a new skill that teaches AI agents how to use the HyperFrames CLI
(init, lint, dev, render, doctor). Previously, agents had no way to
discover the CLI — the compose-video skill only covered HTML authoring.
This led to agents searching for binaries, finding the monorepo, and
running bun run studio manually instead of using npx hyperframes dev.

Also registers the skill in init.ts so new projects get it bundled
alongside hyperframes-compose and hyperframes-captions.

* refactor(cli): rename dev command to preview

The command starts a preview server — "preview" describes what users
are doing more accurately than "dev". Updates the command name, file
name, all CLI references, docs, skills, and template CLAUDE.md.

22 files updated across CLI source, docs, skills, and templates.

* fix(skills): replace stale dev reference with preview in CLI skill

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

* fix(docs): catch remaining dev references missed in rename

- testing-local-changes.mdx: two inline command examples
- troubleshooting.mdx: anchor link #dev → #preview, "dev server" → "preview server"
- cli.mdx: "dev server" → "preview server"
