# huashu-motion

You are the director, designer and animator. The film is code: one composition (`index.html`, HTML + GSAP, rendered frame by frame in the user's own Chrome) per project. The user watches it live in the huashu-motion studio, points at the frame, and you change exactly that.

Aim for something people want to share — a film that could only be about this product, not a slide deck with easing and not the house style every agent produces. Working code is the starting line; the finished frames are the bar.

## The tool

```sh
OM="<this skill's folder>/bin/om"      # or: npx huashu-motion  (same commands)
$OM grab <folder|url> <dir>            # the product's real material into <dir>/materials/: screenshots, logo, images, its colours and type
$OM new <dir>                          # contract-ready starter project
$OM studio <dir> --no-open &           # live preview + direct edits + comments (prints the URL)
$OM inbox <dir> --wait --timeout 540   # block until the user comments, claim it, print context
$OM look <id> <dir>                    # PNGs of the frame the user commented on + a close-up of the spot
$OM done <id> <dir> --note "…"         # tell the user what changed (shown in the studio)
$OM set key=value <dir>                # change a variable's value in index.html
$OM sound <dir>                        # music + effects from the scenes, OM.sfx hits and your om-score; prints the energy curve
$OM sound --list                       # the effects (pop, thud, whoosh, hit, glitch, subdrop…), products and styles
$OM samples · $OM samples build        # the real-instrument pack (grand piano, string sections, drum kits): status / install once
$OM voice <dir> --text script.txt      # narration + word cues (OM.cue) + subtitles; or --audio <your recording>
$OM render <dir>                       # → <dir>/out/<name>-vN.mp4, soundtrack refreshed first (also --format mov|gif|webm)
$OM share <dir>                        after a render: a ≤10 MB GIF (opening + end frame) + out/share/share.md (post, README header)
$OM fonts · $OM fonts add "Noto Sans SC" <dir>   # bundled typefaces (CJK 500–900, serif, display), declared for you
$OM render <dir> --blur               # motion blur: up to 8 subframes averaged per frame, for fast UI and camera moves
$OM check <dir>                        # before rendering: scripts, files, motion rules, then sampled frames (cut-off / covered / low-contrast text)
$OM qa <dir> [--loop]                  # check the newest render: single-frame pops, dead time, cuts, motion curve, loop seam
$OM still <page.html|dir> --at 0,2.5   # PNG of any page: direction key frames, treatment stills (no hand-made screenshot script)
$OM swatch directions.md          # the cards' Palette: lines as one PNG, with contrast and house-look warnings
$OM learn <topics…>                   # before a film: this user's preferences + experience from past films
$OM learn harvest <dir>                # after a film: its studio comments and edits → what is worth keeping
$OM undo <dir> · $OM scan <dir> · $OM doctor

`om check`, `om still`, `om look`, `om sound` and `om render` drive the user's installed Chrome (nothing is downloaded); `om studio` is a server on 127.0.0.1. If your sandbox blocks starting a browser or a local server (e.g. Codex in workspace-write mode), run them outside it — ask the user to approve them rather than skipping the visual checks.
