HyperFrames CLI

Run commands as npx hyperframes ... unless project instructions provide a wrapper. Obey the wrapper when present. The CLI requires Node.js 22 or newer and FFmpeg.

Development loop

  1. Scaffold: npx hyperframes init <project> (centered blank). Or capture a site. Pass --example=<name> only to start from a named example.
  2. Find the move: before authoring motion by hand, search for a primitive that already does it: npx hyperframes catalog --query "reveal a headline one line at a time". Ask for the effect you want rather than the mechanism you have in mind. Install with npx hyperframes add <name> (see /hyperframes-registry). Author by hand only once nothing fits.
  3. Author: write the composition using /hyperframes-core. To know what is on a project's timeline (tracks, clips, starts, ends, what plays), run npx hyperframes timeline --json instead of reading index.html and every sub-composition file: nested rows carry absolute main-timeline absStart/absEnd and their owning file, not just their local, per-sub-composition time. Prefer --json over the text form; it costs fewer tokens for the same or better correctness. See references/upgrade-info-misc.md for one-liners that answer common questions without reading the whole output.
  4. Get fast feedback while editing: run npx hyperframes lint after the first HTML pass and after structural changes.
  5. Run the final gate: run npx hyperframes check; it reruns lint before opening the browser. Do not prepend a redundant standalone lint invocation. Add --snapshots for annotated overview frames and finding crops.
  6. Inspect sub-compositions: when index.html mounts data-composition-src, capture midpoint snapshots and inspect each mounted scene.
  7. Open the final Studio preview: run npx hyperframes preview --background, verify the URL returns HTTP 200, hand the timeline project URL to the user, and ask whether to revise or render. Keep it alive until review ends.
  8. Render only after approval: use --quality draft while iterating, --quality looks for the first real encode (the CLI default), and --quality delivery for final delivery.
  9. Verify the output: confirm the file exists and is non-empty. Read the render summary's second line (beginframe vs screenshot, GPU, stage timings). screenshot + software gpu on Linux is the slow path. ffprobe -v error -show_format -show_streams and compare duration (and fps if the brief set it) to the root data-duration.

Mandatory creator-edit cross-references

  • Before authoring or diagnosing a zoom, punch-in/punch-out, reframe, camera move, or any keyframe motion, read /hyperframes-keyframes first.
  • Before hyperframes keyframes, read /hyperframes-keyframes; the command surfaces animation trajectories and does not diagnose clip cuts.
  • For a cut, trim, splice, reorder, or source timing edit, read /hyperframes-core and use its clip/timeline contract.
  • For fade-in/fade-out, crossfade, track gain, volume automation, ducking, voiceover carve, or FX on placed audio, read /hyperframes-audio. Load core alongside it when clip placement or picture timing also changes.
  • Use /media-use only to source/generate media or preprocess a derived asset. Copy creator edit markup from /hyperframes-corereferences/creator-editing-recipes.md.
# Fast iteration check; repeat while authoring as needed.
npx hyperframes lint

# Required final gate; includes lint.
npx hyperframes check
npx hyperframes preview --background
npx hyperframes render --quality looks --output out.mp4
test -s out.mp4
ffprobe -v error -show_format -show_streams out.mp4

check runs lint first, then uses one browser session and one seek pass to audit runtime errors, failed requests, layout, *.motion.json assertions, and WCAG contrast. Persistent findings gate the exit code; transient entrance or exit findings are informational. Use --strict to gate warnings. validate, inspect, and layout remain aliases for compatibility but must not appear in new instructions or scripts.

Preview before render

Open the final composition preview (#project/<name>) only after check passes, to review the assembled timeline. The plan in chat and the storyboard.html sketch sheet are not approval of the final video. Rendering always requires the final approval defined by hyperframes/references/review-loop.md.

Sub-composition smoke test

Static audits cannot catch every mount failure. When the project uses sub-compositions, capture at least one visible midpoint for each host slot:

npx hyperframes snapshot --at <t1>,<t2>,<t3>

Treat tiny unstyled content, canvas-sized icons, missing hero elements, or timeline-registration timeouts as render-blocking mount defects. See hyperframes-core/references/sub-compositions.md for the corresponding fixes.

Agent conventions

  • Search the catalog before writing motion by hand. npx hyperframes catalog --query "<the beat, in plain English>". Search is entirely local: there is no hosted tier, no account, and the query text is never sent anywhere. By default it ranks on vocabulary shared with the item's name, title and description, which misses any phrasing that does not reuse the catalog's own wording. Add --on-device to rank by meaning instead (see the offline tier below).

  • Query in English even when the video is not. Both tiers index an English catalog, so a query in another script produces no searchable terms and returns nothing. Describe the move in English; the on-screen copy stays in whatever language the video needs. No searchable words in query means exactly this and is not a missing component, so do not report it as a catalog gap.

  • Read which tier answered; never infer it from results appearing. With --json the envelope carries query, tier (on-device or words), tier_detail, dropped, unindexed, shown, total and results, plus top_score when the answering tier produces one and warnings when a tier was asked for and could not run, or when a search returned nothing and a better tier is still waiting on someone's consent. A weak result on words is expected; the same result on on-device is a bug. top_score is on-device only and has no threshold behind it: the ranker returns the whole catalog in some order for every query, so read it as evidence rather than as a pass or fail.

  • dropped and unindexed are opposite skews between the registry and the on-device index, and rewording the query fixes neither. dropped counts ranked names this registry cannot install, so the strongest matches are the ones being lost. unindexed counts registry moves the index cannot see at all, which no query can ever return. Refreshing the registry is not the answer to either: its manifest carries a 24h TTL and heals itself, while the vectors are a separately published artifact fetched into ~/.hyperframes/catalog/. Re-running with --on-device refetches that index when unindexed is above zero, so that is the remedy to hand the user. A pure over-coverage skew (dropped above zero while unindexed is zero) does not trigger the refetch; clearing ~/.hyperframes/catalog/ is the only way out of that one. Both counts are of names rather than of results, so either can exceed total.

  • When a search comes back with nothing worth installing, say so. npx hyperframes feedback --search-miss "<the query you ran>" --wanted "<the move you needed>" --tier <the tier that answered>. You do not have to assemble that line: catalog --query prints it pre-filled, and every --json search envelope carries it as report_gap with the query and tier already correct — fill in --wanted and send. This is the only path that sends a query anywhere, and it is a separate deliberate command precisely so plain catalog --query keeps its promise of sending nothing. Report on either tier, whenever the results do not do the thing; do not hold out for the on-device tier, which needs a consented 33 MB download and is therefore off in most agent runs — waiting for it means never reporting at all. The tier rides along in the report, so a vocabulary miss stays distinguishable from a meaning miss without you having to judge which one you hit. What comes back is a list of moves the catalog does not have yet, read directly rather than guessed from install counts, so the phrasing that matters is the effect you wanted, not the item name you imagined. It carries no rating and never lands in the rating metric.

  • Offer the offline tier; never enable it silently. A one-time ~33 MB download (a quantized ONNX build of bge-small-en-v1.5 plus its tokenizer, pinned to a fixed revision) and the catalog vectors from the registry, both cached under ~/.hyperframes/, neither added to the project or any package. Once cached it ranks by meaning with nothing sent. Say the size out loud and let the person decide, then pass --on-device (with -y to skip the prompt) once they agree. The interactive offer only fires on a TTY. Under --json there is no prompt, but a search that found nothing puts the same ask in warnings, so read that array and put the decision to the user yourself.

  • Prefer --json for agent and CI calls. Server-mode render, preview, and play do not provide ordinary JSON output; preview --selection --json and preview --context --json are query-mode exceptions.

  • doctor --json always exits zero. Gate on its payload:

    npx hyperframes doctor --json | jq -e '.ok' >/dev/null
    
  • Non-TTY mode is automatic and scaffolds the centered blank. Pass --example only to start from a named example. Use --non-interactive to force flag-only mode on a TTY.

  • Use one HYPERFRAMES_RUN_ID for all commands in the same verification loop.

  • Use --strict, --strict-all, and --strict-variables when the corresponding warnings, variables, or CI conditions must gate the render.

  • JSON paths redact the home directory as $HOME; do not try to reverse the redaction.

  • When a hosted cloud project approaches or exceeds the 200 MB upload limit, use cloud render --dry-run --json and follow the .hyperframesignore investigation in references/cloud.md. Never ignore an asset merely because it is large.

  • Never render merely because checks pass. Pause at the final preview and wait for approval.

Studio-directed edits

When the user refers to “this element” or the current selection, query Studio instead of guessing:

npx hyperframes preview --context --json --context-fields selection

Use selection.target.hfId when available, otherwise its selector and source file. If the result reports no-selection, ask the user to click the element and rerun. Request only the context slices you need; use --context-detail full only for computed styles or editable text metadata. Full behavior and failure codes live in references/preview-render.md.

Self-managed distributed GCP rendernpx hyperframes cloudrun render <project> --width 1920 --height 1080 --wait

Skill attribution is automatic — the examples above need no --skill. A project scaffolded by a workflow (hyperframes init --skill=<workflow>) records its owning skill in hyperframes.json, and every later render inherits it on anonymous telemetry: re-renders, npm run render, and --batch alike. Pass --skill=<slug> explicitly only to stamp a project that was not created through a workflow (its first render then persists it).

Use cloud rendering when the user wants hosted rendering without local Chrome, FFmpeg, or AWS. Use Lambda only when AWS ownership is a requirement. Use Cloud Run only when GCP ownership is a requirement. Read the matching reference before running any cloud path.

After verifying a successful render, send one feedback report unless telemetry is disabled or the user opted out:

npx hyperframes feedback --rating <0-10> --comment "<specific result or friction>"

Keep clean-run feedback concise. For any bug or friction, capture a reproduction packet before submitting; do not send only a symptom summary. Include the rerunnable command (relative to the project directory — feedback is submitted to a public channel, so do not paste absolute paths, home-directory prefixes, or user/machine identifiers), expected versus actual behavior, exact error (also strip absolute paths from stack traces — keep basename + line, drop the leading directory), whether output completed/fell back/failed, workaround, and repro-project status. For a rating ≤ 7 that describes a visual defect (black frame, flicker, corrupt output, wrong frame, blank output, other visual anomaly), also include a COMPOSITION_STRUCTURE: block — a privacy-preserving structural anatomy (element census + attribute presence + timeline shape) so maintainers can pattern-match against known bug families without the composition ZIP. Agents auto-fill this via the composition-census helper; the human user does not fill it by hand. If the issue did not reproduce again, say so and still include the last failing command and logs. Use --file-issue only with consent: it publishes a minimal reproduction to a public URL. The required packet format and privacy warning live in references/preview-render.md.

Read the matching reference before running a command

The following references and owning skills are mandatory command contracts, not optional background reading. Before running a command in the table, read its matching row.

Google Cloud Run deployment and renderingreferences/cloudrun.md
info, upgrade, compositions, timeline, docs, benchmark, telemetry, media preprocessingreferences/upgrade-info-misc.md

For composition variables, also read /hyperframes-corereferences/variables-and-media.md. For hyperframes add and hyperframes catalog, use /hyperframes-registry. Before hyperframes present, read /slideshow; before hyperframes keyframes, read /hyperframes-keyframes. For TTS, transcription, captions, or background removal choices, use /media-use.

The specialized commands are deliberately documented by their owning workflows:

npx hyperframes present <project-dir> --port 3004 --no-open
npx hyperframes beats <project-dir> --json
npx hyperframes keyframes <project-dir> --json
npx hyperframes media-treatment --capabilities
npx hyperframes figma asset KEY:10-20

present serves a navigable deck with presenter and audience synchronization. beats is the standalone Studio beat-grid utility defined in references/beats.md. keyframes surfaces seek-safe animation and motion-path diagnostics. media-treatment discovers, applies, and clears deterministic looks on local footage — start with --capabilities for the overview and --capability <name> for one family; /media-use owns which treatment a brief is asking for. figma imports over the REST API with the asset, tokens, and component subcommands and needs FIGMA_TOKEN; motion and shader import have no REST endpoint and are agent-only, so /figma owns those.

Commands you should not run

Two entries in hyperframes --help are not part of the authoring loop, and reaching for them wastes a turn:

  • events is the telemetry endpoint skills use to report their own invocation, ideally from a bundled script. It emits an anonymous event and exits 0 no matter what you pass it. It is not a way to read telemetry back, and an agent has no reason to call it by hand.
  • validate, inspect, and layout are deprecated aliases kept for old scripts. check is the one that is maintained, and it is what every reference in this skill assumes.

Individual skills in this repo

This repo contains 20 individual skills — each has its own dedicated page.

embedded-captions

>

faceless-explainer

Turn arbitrary text — an article, notes, a topic, a brief — into a faceless explainer video: there is no site or footage to capture, so the visuals are invented per scene (typography, abstract graphics, diagrams, data-viz). Use for topic explainers, concept breakdowns, how-tos, listicles. Not a video built from a website (/product-launch-video — promo or tour). Unclear → /hyperframes.

figma

Import Figma content into a HyperFrames composition — rendered assets, brand tokens, components, storyboard sections → reconstructed motion (frames read as states, not slides) (REST/CLI), connector-assisted motion when available, and shaders from a connector or native export. Use when the user pastes a figma.com link or asks to bring a Figma design, frame, logo, brand, or animation into a video/composition.

general-video

>

heygen-com/animejs

Anime.js adapter patterns for HyperFrames. Use when writing Anime.js animations or timelines inside HyperFrames compositions, registering animations on window.__hfAnime, making Anime.js seek-driven and deterministic, or translating Anime.js examples into render-safe HyperFrames HTML.

heygen-com/changelog-video

Turn a weekly changelog .md into a finished branded changelog video (square 1080, ~45-60s, Annie VO, animated brand background, mock-UI visualizations, lowkey captions). Use when the user provides a changelog/digest markdown and wants the weekly video, or says "changelog video". Self-contained — fonts, background, lexicon, and scripts ship in this skill.

heygen-com/claude-design-hyperframes

Use when running inside Claude Design specifically. Produces a valid, brand-accurate HyperFrames video draft using pre-valid skeletons. For Claude Code / Cursor / Codex, use the `hyperframes` skill instead.

heygen-com/contribute-catalog

Author a new HyperFrames registry block (caption style, VFX block, transition, lower third) or component (text effect, overlay, snippet) and ship it as an upstream PR to the hyperframes repo. Use ONLY when the user wants to CONTRIBUTE to the public catalog — for in-project caption/transition authoring use the `hyperframes` skill, for installing existing registry items use the `hyperframes-registry` skill.

heygen-com/css-animations

CSS animation adapter patterns for HyperFrames. Use when authoring CSS keyframes, animation-delay based timing, animation-fill-mode, animation-play-state, or CSS-only motion that HyperFrames must seek deterministically during preview and rendering.

heygen-com/cut-the-curve

The technique catalog: five velocity-matched SEAMS (zoom-through, INVERSE zoom-through, cut-the-curve, waterfall cut, rack-focus blur-cut) plus the two in-scene techniques — waterfall ENTRY (staggered arrival cascades for title cards / segment openers) and the nudge curve (slow-fast-slow three-phase group slides). Covers partial-travel (~12% of frame) velocity matching via mirrored power4 eases, the Z scale-sign rule, size-scaled blur (10px text / 18-20px full-frame), word-by-word staggered cuts, cascade pacing by element weight, and the 10/65/25 slide ratio. Read before authoring any transition, text-beat handoff, kinetic text entry, or group reposition. [depth, zoom, inverse-zoom, scale-sign, mirrored-zoom, rack-focus, pacing, velocity, cut-the-curve, waterfall, stagger, cascade, kinetic-text, title-card, segment-opener, nudge, slide, easing, group-motion, z-depth, motion-graphics, cinematic, transition, blur, directional-continuity]

heygen-com/gsap

GSAP animation reference for HyperFrames. Covers gsap.to(), from(), fromTo(), easing, stagger, defaults, timelines (gsap.timeline(), position parameter, labels, nesting, playback), and performance (transforms, will-change, quickTo). Use when writing GSAP animations in HyperFrames compositions.

heygen-com/hyperframes-media

Asset preprocessing for HyperFrames compositions — multi-provider TTS (HeyGen / ElevenLabs / Kokoro local), multi-provider BGM (Google Lyria / local MusicGen), Whisper transcription, background removal, and caption authoring. Use for npx hyperframes tts, bgm, transcribe, remove-background, voice/provider selection, music-mood prompting, captions / subtitles / lyrics / karaoke / per-word styling.

heygen-com/lottie

Lottie and dotLottie adapter patterns for HyperFrames. Use when embedding lottie-web JSON animations, .lottie files, @lottiefiles/dotlottie-web players, registering instances on window.__hfLottie, or making After Effects exports deterministic in HyperFrames.

heygen-com/seam-craft

Render-correctness doctrine for scene-to-scene seams in HyperFrames launch videos — the prerequisites that make transitions composite correctly on the master timeline. Load when assembling the master timeline / index.html, when a white flash appears at a cut or crossfade seam (especially on dark films), when reasoning about why a transition opacity dip shows through, or when verifying the render-side mechanics of how overlapping scene wrappers blend. Covers the opaque stage-ground (#root background) white-flash guard and how the injector overlaps wrappers, holds final frames, ping-pongs tracks, and stamps lint-clean template code onto the master timeline. Does NOT contain the per-transition catalog — see the transition registry for individual transition entries.

heygen-com/tailwind

Tailwind CSS v4.2 browser-runtime patterns for HyperFrames compositions. Use when scaffolding or editing projects created with `hyperframes init --tailwind`, writing Tailwind utility classes in composition HTML, adding CSS-first Tailwind v4 theme tokens, debugging v3 vs v4 syntax, or deciding when to compile Tailwind to CSS instead of using the browser runtime.

heygen-com/three

Three.js and WebGL adapter patterns for HyperFrames. Use when creating deterministic Three.js scenes, WebGL canvas layers, AnimationMixer timelines, camera motion, shader-driven visuals, or canvas renders that respond to HyperFrames hf-seek events.

heygen-com/typegpu

TypeGPU and raw WebGPU adapter patterns for HyperFrames. Use when creating GPU-rendered compositions with TypeGPU, raw WebGPU, WGSL fragment shaders, compute pipelines, liquid glass effects, particle systems, or any canvas layer driven by navigator.gpu that responds to HyperFrames hf-seek events.

heygen-com/waapi

Web Animations API adapter patterns for HyperFrames. Use when authoring element.animate() motion, Animation currentTime seeking, document.getAnimations(), KeyframeEffect timing, fill modes, or native browser animations that must render deterministically in HyperFrames.

heygen-com/website-to-hyperframes

Capture a website and create a HyperFrames video from it. Use when: (1) a user provides a URL and wants a video, (2) someone says "capture this site", "turn this into a video", "make a promo from my site", (3) the user wants a social ad, product tour, or any video based on an existing website, (4) the user shares a link and asks for any kind of video content. Even if the user just pastes a URL — this is the skill to use.
