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

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 (#201)
* 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) - Fix composition audio example to use actual <audio> element pattern - Keep non-obvious workflows: TTS+transcribe for captions, long scripts Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs(tts): add guidance for using external TTS sources Help users understand when to use cloud TTS (voice cloning, broader languages, higher quality) vs the built-in Kokoro model, and how external audio integrates into the same composition workflow.

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 [Screen Recording 2026-04-02 at 1.56.30 AM.mov <span class="graphite__hidden">(uploaded via Graphite)</span> <img class="graphite__hidden" src="https://app.graphite.com/user-attachments/thumbnails/53b03f4e-538e-477a-b738-7a033b99a84e.mov" />](https://app.graphite.com/user-attachments/video/53b03f4e-538e-477a-b738-7a033b99a84e.mov) 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

fix(studio): address caption designer PR feedback (#200)
* fix(studio): address caption designer PR feedback Fixes from review comments on feature/caption-designer (#180): - fix(generator): guard named colors in hexToRgba — "red", "transparent" no longer produce NaN rgba values - fix(sync): log auto-save failures instead of silently swallowing them - fix(sync): check res.ok before parsing caption-overrides response - refactor(components): extract Section, Row, inputCls into shared.tsx to eliminate duplication between CaptionPropertyPanel and CaptionAnimationPanel - fix(store): replace non-deterministic Date.now()+Math.random() ID with counter-based group IDs - fix(store): read selectedGroupId from state param instead of get() to avoid stale reads in batched set() calls - fix(overlay): remove cssScale multiplier from getBoundingClientRect coords — the browser already accounts for CSS transforms - 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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(studio): remove animation tab and typography/color from property panel Keep only Position (X, Y) and Transform (Scale, Rotation) controls. Remove tab switcher UI since there's only one view now.

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 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

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

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.

fix(lint): detect GSAP animations targeting clip elements (tab crash) (#114)
* fix(lint): detect GSAP animations targeting clip elements (tab crash) The runtime manages clip visibility via inline styles. When GSAP also writes inline styles on the same element, both systems trigger style recalculations every frame, creating a runaway loop that crashes the browser tab. New rule gsap_animates_clip_element (error severity): - Builds map of all elements with class="clip" (by id and class) - Checks if any GSAP selector resolves to a clip element - Nested selectors like "#overlay .title" are correctly ignored - Merged into existing GSAP script loop (no redundant parsing) * fix: remove non-null assertions and add missing test coverage - Replace `!` assertions with optional chaining in lint.ts and tests - Add shouldBlockRender tests for --strict-all without --strict - Add clip element test for class-only detection (no id) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix: use optional chaining for array access in lintProject tests TypeScript's strict mode flags array indexing as possibly undefined.

data-in-motion.md — minimal guide for data/stats in video: - Visual continuity: related data stays in same visual space - Numbers need visual weight: pair metrics with fills/shapes - Avoid web patterns: no pie charts, dashboards, axes, legends house-style.md refinements from eval iterations: - Layout approach variety (step 4 in Before Writing HTML) - Explicit weight contrast requirement - SVG illustration anti-default - Overlap anti-default - Ambient motion variety (not always zoom) SKILL.md — added reference to data-in-motion.md Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com> |

fix(skill): house style anti-defaults for SVG, overlap, and zoom (#68)
## Summary - Anti-default: don't draw real-world objects with SVG paths — they look crude. Geometric shapes and abstract forms only. - Anti-default: every element needs clear space — overlapping text is always ugly. - Replaced zoom-in monoculture in choreography — now offers 6 ambient motion options instead of always zooming. - Added scene pacing: build/breathe/resolve phases. Follow-up to the house style PR (#59, merged). These fixes came from visual review of 20+ eval compositions. ## Test plan - [ ] Generate a composition with a sparse prompt and verify no SVG illustrations of real objects - [ ] Verify elements don't overlap in generated compositions - [ ] Verify ambient motion varies (not always zoom-in) 🤖 Generated with [Claude Code](https://claude.com/claude-code) |

feat(skill): house style guide for compose-video (#59)
* feat(cli): non-interactive by default, --human-friendly for UI Following ElevenLabs CLI pattern: default mode is agent-friendly (flag-driven, plain text output, fail fast on missing args). Interactive clack UI is opt-in via --human-friendly. Init command: - --template required in default mode (errors with example if missing) - --video / --audio flags for media input - --skip-skills / --skip-transcribe to control optional steps - --human-friendly enables the existing interactive prompts - --help shows examples for every flag combination - Transcription runs automatically in default mode (unless --skip-transcribe) - Plain console.log output, process.exit(1) on errors Skills command: - Added --human-friendly flag - Added examples to --help output Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(cli): improve --help documentation and add --yes/--check to upgrade - upgrade: add --yes and --check flags to skip interactive prompt - benchmark: clarify description — preset fps/quality/worker configs - browser: describe each subcommand (ensure/path/clear) in help - docs: list available topics inline in --help output Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(skill): add house style guide with motion defaults, palettes, and anti-defaults When no visual-style.md is provided, compose-video now follows house-style.md for professional output quality. Includes: - Motion: easing variety, timing, entrance patterns, choreography - Sizing: text scale contrast, element fill, travel distance - Visual depth: gradient/shadow/texture guidance - Typography: weight contrast, tracking, case - Anti-defaults: table of generic AI patterns to avoid - 72 curated color palettes across 9 categories - Content interpretation: generate real content, not prompt text Eval-validated across 5 iterations with 50+ test compositions. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(skill): add container anti-default and typography guidance - Anti-default: discourage card/container patterns in favor of content placed directly on canvas (professional video style vs web UI style) - Typography section: weight contrast, deliberate case, tracking, one typeface at two weights - Visual depth: softened to avoid templating (content-appropriate, not every-composition-the-same) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat(skill): add scene pacing guidance to house style Three-phase composition structure: build (staggered entrances), breathe (subtle motion to keep holds alive), resolve (fast exits with intention). Prevents front-loading all animation into the first second and dead static holds. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(skill): replace zoom-in monoculture with ambient motion variety The viewport scale and end emphasis code examples were being copied verbatim to every composition. Now offers 6 ambient motion options (pan, rotation, scale in/out, parallax, color shift, stillness) and 4 ending options instead of always zooming.

feat: add HyperFrames skills for AI coding tools (#46)
## Summary
- 2 skills in `skills/` directory (tool-agnostic, installed via `hyperframes skills`)
- **compose-video** (112 lines): Core HyperFrames composition authoring contract — data attributes, timeline, video/audio rules, GSAP constraints, editing consistency
- `patterns.md`: PiP, title card, slideshow examples (loaded on demand)
- **captions** (138 lines): Tone-adaptive caption styling from transcript analysis — per-word styling, script-to-style mapping, whisper.cpp format reference
## Test plan
- [ ] Skills load in Claude Code
- [ ] compose-video under 500 lines, no `assets/` or `fonts/` references
- [ ] Captions skill triggers on tone detection keywords
