What it does

Render Stopmotion Hand Swatch Cycle is an agent skill from gooseworks-ai/goose-skills. Assemble a stop-motion hand-swatch-cycle product-demo ad from a config — a sequence of still PLATES (one hand swiping a single-barrel product across a test surface, the barrel + swatch changing per plate while the hand, background, crop, and lighting stay locked) is PNG→mp4 loop-encoded at each plate's own stop-motion hold (fast motion frames 150–250ms, per-shade ~380ms, hero beats 1100–1800ms), concat-demuxed with HARD cuts into a silent master, closed on a Playwright HTML-rendered branded end card (serif…

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts (for example `scripts/PIPELINE.md`, `scripts/README.md` and `scripts/config.example.json`).

It sits in Media & Creative, covering Image generation, Text to speech and voice and Positioning and messaging. It works with ElevenLabs and Playwright. The repository describes itself as: Library of Growth & GTM skills + data APIs for Claude Code, Codex, Cursor to run ads, social, content, lead gen, seo and data scraping. The licence is MIT.

When your agent uses it

  • The stopmotion-hand-swatch-cycle format
  • Tasks that involve Image generation
  • Tasks that involve Text to speech and voice

Example prompts

  • “/render-stopmotion-hand-swatch-cycle”

What it can do on your machine

Read from SKILL.md and the folder at commit c650c6d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/, which the agent can run.

    Shell commands in SKILL.md call:

    • ffmpeg

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Render Stopmotion Hand Swatch Cycle loads about 1.2k tokens when it runs. Until then it costs about 253 tokens; SKILL.md has 563 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~253
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

This is the FREE deterministic assembly stage (loop-encode + concat-demux + end-card render + music mux); the master-anchor plate, shade plates, and end-card BG come from create-image-gpt-image-fal and the track from create-music-elevenlabs.

render-stopmotion-hand-swatch-cycle

Assemble a stop-motion hand-swatch-cycle ad from a config: a fast, tactile product demo where a single hand swipes ONE product barrel across a test surface, and the shade of the barrel AND the painted swatch stripe changes on every frame while the hand, background, crop, and lighting hold still — cycling the variant family so the viewer self-identifies their match, then a hero-pick payoff and a branded end card. The hand, background color, test surface, hero variant and music are the recipe's user choices; this capability only assembles the plates it is given. This capability is the FREE, deterministic assembly — the per-plate PNG→mp4 loop encode, the concat-demux, the end-card render, and the music mux.

scripts/config.example.json is the worked example — reference only, never the default (DIBS Beauty "Pick Your Match": a fair hand, bubblegum-pink background, cream skin-patch; ~16.6s 1080×1920 9:16, ~24 cycle plates + finale beats + a 3s end card); scripts/PIPELINE.md maps every config block to its source step and scripts/README.md documents the free assembly.

Run

This is the FREE, deterministic assembly stage — it spends nothing. The paid inputs are separate capabilities — the master-anchor plate + the per-shade / motion / finale plates + the end-card hero BG (create-image-gpt-image-fal, gpt-image-2 EDIT mode, each plate anchored to the SAME master-anchor — never chained), and the music track (create-music-elevenlabs, or a brand-supplied mp3). Given the ordered plate PNGs + per-plate holds + the end-card hero BG + the brand logo SVG + the music track, render-stopmotion-hand-swatch-cycle loop-encodes each plate at its hold, concat-demuxes with hard cuts into a silent master, appends the HTML-rendered end card, and muxes the music under it → the master. Re-cuts (re-timed holds, a re-ordered cycle, a swapped end card) reuse the existing plates / track and cost $0.

Contract (the free assembly)

  • Still plates, not i2v — held for tuned durations. Each plate is a static PNG loop-encoded (ffmpeg -loop 1 -t <pose_hold_ms>) to 1080×1920 @ 30fps crf18. This is stop-motion — discrete held frames, no camera moves, no character animation. Do not animate the plates.
  • Fast stop-motion cadence, HARD cuts. Motion / half-painted plates hold 150–250ms, per-shade plates ~380ms (or ~1000ms for a slower cycle), hero / bookend beats 1100–1800ms; average ~380ms. Concat-demux the plate mp4s in order with hard cuts (ffmpeg -f concat) — NO dissolves. The frame-swap tactility is the whole point; a crossfade erases it.
  • Concat-demux, not filter_complex. The plates are silent stills, so the concat demuxer over the ordered plate list is correct and cheapest. (filter_complex is only needed when clips carry mismatched audio — these don't.)
  • The music carries it — no VO. A pre-sourced or generated instrumental in the chosen feel (the demo's was ~128 BPM bright pop), volume ≈0.4, fade in/out. Do not add a spoken voiceover or a second bed.
  • End card via Playwright HTML from the real logo SVG — never AI-render brand text. A serif tagline + sans subtitle + the real logo SVG composited over a hero product/swatch BG by an HTML template (Chromium headless), rendered to a silent ~3s clip. A diffusion model garbles a wordmark.
  • Music plays UNDER the end card with a fade tail — no silent tail. Mux the track over the whole video including the end card, fade over the last ~0.5s so the video ends WITH the music.
  • FFmpeg composite, deterministic, FREE. Loop-encode each plate, concat-demux on hard cuts, append the end card, mux the music with a fade tail → a 1080×1920 h264+aac master (~16.6s). No paid calls, no keys (beyond the Playwright/Chromium the end-card render needs).
