* feat(player): expose picture size, durationchange and a click-to-play opt-out
- compositionWidth/compositionHeight are public, ready carries them, and a
resize event fires when the picture size changes.
- durationchange fires when the duration changes after ready, on both the
runtime and the direct-timeline paths.
- disable-click-to-play leaves clicks on the picture to the host.
Nothing changes for a player that does not use the new attribute; ready's
detail only gains two fields.
* docs(player): say composition size, one doc line per size getter
* fix(player): apply scenes before ready fires, keep the zero-size warning, document the new API
* fix(player): fire a message's events after the whole message is applied
* fix(player): queue every player event behind the update that raised it
* fix(player): decide autoplay after ready listeners run, and restart a loop at time 0
* fix(player): keep raising events after a listener throws
* refactor(player): drop a comment the ordering test already pins
* fix(player): fire the rest of an update's events when a listener throws
* perf(player): let paused players check in once a second with low-power-idle
* refactor(player): trim low-power-idle comments and tidy its test
* fix(core): keep the fast paused heartbeat until a timeline is bound
* fix(core): wait for sub-compositions to bind before slowing the paused heartbeat
* fix(player): a play() made while the composition loads still plays
The iframe's own load event reset the asset wait, and that reset also cleared the queued play,
so a play() between the first ready and load was dropped with no error. Play intent now leaves
the asset-wait reset: only pause, seek, disconnect and a new src or srcdoc clear it.
Also adds assets-loading-ui (player | none): none never shows the loading-assets card, while
the assets-loading attribute and the assetsready and painted events still fire.
* fix(player): switching the loading card off keeps a shader load on screen
* fix(player): the loading card and a shader load no longer hide each other

## 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.
* fix(studio): support web-component refs in useTimelinePlayer
The studio's `useTimelinePlayer` hook returns an `iframeRef` that
consumers attach to an `<iframe>` element. When consumers wrap the
iframe in a custom element (e.g. `<hyperframes-player>`) that puts
the iframe inside its shadow DOM, every `iframeRef.current.contentWindow`
access returned `null` and `getAdapter()` silently failed — meaning
timeline seek, play, pause, and `refreshPlayer` all became no-ops.
Changes:
- Add `resolveIframe(el)` helper that returns the underlying iframe
whether the host is the iframe itself, a custom element with a
shadow-DOM iframe, or a wrapper with a descendant iframe.
- Export `resolveIframe` from the studio so consumers can pre-resolve
the iframe before assigning it to `iframeRef`.
- Internal `useTimelinePlayer` keeps the strict `HTMLIFrameElement`
ref type, so existing consumers attaching directly to an `<iframe>`
are unaffected.
Also adds:
- JSDoc on the player's `iframeElement` getter.
- "Advanced: iframe access" docs section in `packages/player/README.md`
and `docs/packages/player.mdx`.
- Type-safety lint rules in `.oxlintrc.json` and a "Type-safety
conventions" section in `CONTRIBUTING.md`.
Backward compatible — App.tsx and NLELayout.tsx continue to work
unchanged.
* chore(lint): defer no-explicit-any rule; it broke existing codebase
The new rules added 37 errors across 32 existing files — mostly
legitimate `window as any` casts at browser-global and test-mock
boundaries. Enabling them without fixing all violations breaks CI.
Revert the `.oxlintrc.json` additions and soften the CONTRIBUTING.md
wording to describe the convention without claiming lint enforcement
(that enforcement will come in a follow-up PR that fixes all sites).
## Summary
Two independent initiatives that improve agent DX and expand HyperFrames' reach.
### Initiative 1: Fix the Clip Animation Footgun
- `gsap_animates_clip_element` lint rule now uses smart detection — only errors when GSAP animates `visibility` or `display` on a clip element
- All other properties (opacity, transform, x, y, scale, etc.) are allowed silently
- This was the #1 agent failure in QA (10/10 agents hit it on v0.2.1)
### Initiative 2: `<hyperframes-player>` Web Component
- New `@hyperframes/player` package — zero dependencies, 3.3KB gzipped
- Iframe-based web component with Shadow DOM for perfect isolation
- Video-like API: `play()`, `pause()`, `seek()`, `currentTime`, `duration`, events
- Controls overlay with play/pause, scrubber (mouse + touch), time display, auto-hide
- Full docs page at `docs/packages/player.mdx`
## Before / After
### Clip animation lint
**Before (10/10 agents hit this):**
```
✗ gsap_animates_clip_element: GSAP animation targets a clip element.
Selector "#title" resolves to element <div id="title" class="clip">.
The framework manages clip visibility — animate an inner wrapper instead.
Fix: Wrap content in a child <div> and target that with GSAP.
```
**After (only errors on actual conflicts):**
```
# This passes lint — no error:
tl.from("#title", { opacity: 0, y: -50, scale: 0.8 }, 0);
# This still errors — actual conflict with runtime:
tl.to("#title", { visibility: "hidden" }, 3);
✗ gsap_animates_clip_element: GSAP animation sets visibility on a clip element.
Fix: Remove the visibility/display tween. Use opacity for fade effects.
```
### Embeddable player
**Before:** No way to embed a composition in a web page.
**After:**
```html
<script src="https://cdn.jsdelivr.net/npm/@hyperframes/player"></script>
<hyperframes-player src="./composition/index.html" controls></hyperframes-player>
```
```js
const player = document.querySelector('hyperframes-player');
player.play();
player.pause();
player.seek(2.5);
player.addEventListener('ready', (e) => console.log('Duration:', e.detail.duration));
```
## Test plan
- [x] 427 core tests pass (20 GSAP lint tests with smart detection)
- [x] 7 player tests pass (formatTime + element registration)
- [x] TypeScript compiles cleanly (core + player)
- [x] Lint: GSAP animating clip with safe props → 0 errors
- [x] Lint: GSAP animating clip with `visibility` → 1 error (correct)
- [x] Player builds to 3.3KB gzipped ESM
- [x] Lockfile updated for CI
- [x] Docs page added at `docs/packages/player.mdx`
