What it does

Compose Creator Layer is an agent skill from gooseworks-ai/goose-skills. Composite a generated creator track into a product layer, per beat — in the creator's zone on split beats (either side of a seam), full frame on creator beats, hidden on product beats — with the creator's voice as the audio (loudness -14 LUFS) and an optional ducked music bed, or a music-only or silent master for voiceless formats. Free, local ffmpeg. Pairs with footage-cutlist (the layer) and create-creator-takes-h3 (the creator). Use for split-screen (with an optional zoom and brand-colour seam bar)…

Its SKILL.md is about 810 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts (for example `scripts/compose.py`, `skill.meta.json` and `tests/smoke-test.md`).

It sits in Media & Creative, covering Video production. It works with FFmpeg. 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

  • Split-screen (with an optional zoom and brand-colour seam bar)
  • Screen-insert and any creator-over-product format

Example prompts

  • “/compose-creator-layer”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Crop from the take's real size, never a hard-coded height. A hard-coded 1080 once
  2. No grade. Chasing a saturation or warmth reading was tried twice and both looked
  3. The voice leads. A music bed is ducked under the voice (sidechain); the mix is
  4. Captions come after this (caption-burn, transcribed from this output).

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 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    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

Compose Creator Layer loads about 807 tokens when it runs. Until then it costs about 145 tokens; SKILL.md has 372 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~145
When it runs · the whole SKILL.md, loaded when a task matches
~807

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.

Composite a generated creator track into a product layer, per beat — in the creator's zone on split beats (either side of a seam), full frame on creator beats, hidden on product beats — with the creator's voice as the audio (loudness -14 LUFS) and an optional ducked music bed, or a music-only or silent master for voiceless formats. Free, local ffmpeg. Pairs with footage-cutlist (the layer) and create-creator-takes-h3 (the creator).

Run

bash
python compose.py --layer layer.mp4 --beats cutlist.aligned.json --creator creator.mp4 \
    --out reel.mp4 [--music bed.mp3 --music-db -20] [--head 0.30] \
    [--zoom 1.15] [--divider '#RRGGBB' --divider-px 4]
  • --layer: footage-cutlist cut.py output rendered from the same cut list as --beats (re-render it after align_beats.py). --draft layers are refused.
  • --creator: create-creator-takes-h3 join_takes.py output, reel time from 0.
  • --audio creator|music|none: the voice (+ ducked --music), the --music bed alone (voiceless paid ads), or a silent master (organic posts: the track is added in-platform at upload, which is licensed for organic use only).
  • The creator track may be shorter than the reel (a 2.3s reaction hook): it only shows during its own creator beats.
  • --head: where the crop sits vertically when the creator is scaled to cover an area (0 keeps the top, 0.5 centres). 0.30 keeps the head in the upper third.

Split screen

The split-screen creator look (product on top, the creator talking below) is this atom with split beats; it replaces render-split-screen-creator.

  • The product zone comes from the layer: in the footage-cutlist cut list set the seam (even, about 52% of the height for product on top) and creator_side: "bottom", fit each 16:9 product clip by width, and set bg: "blur" so the margins are a darkened blur of the same clip, never black bars. Window each clip to the moment that proves its line; never loop a short clip.
  • The creator zone: --zoom 1.15 to 1.2 with --head pushes a webcam-distance take in to head and shoulders. Tune it by eye against the reference; a re-run is free. Zoom cannot rescue a take shot too close, so the creator still should be a candid medium shot (chest up, real room), not a plain-background headshot.
  • The seam: --divider '#RRGGBB' draws a brand-colour bar centred on the seam (default 4 px, even) on split beats only.
  • Audio: the creator's voice is the whole bed; leave out --music for this look.

Rules

  1. Crop from the take's real size, never a hard-coded height. A hard-coded 1080 once cropped the top half of an upscaled take and blew it up.
  2. No grade. Chasing a saturation or warmth reading was tried twice and both looked wrong. The take goes in as generated.
  3. The voice leads. A music bed is ducked under the voice (sidechain); the mix is normalised to -14 LUFS.
  4. Captions come after this (caption-burn, transcribed from this output).

Compose Creator Layer is an agent skill from gooseworks-ai/goose-skills. Composite a generated creator track into a product layer, per beat — in the creator's zone on split beats (either side of a seam), full frame on creator beats, hidden on product beats — with the creator's voice as the audio (loudness -14 LUFS) and an optional ducked music bed, or a music-only or silent master for voiceless formats.

When should I use Compose Creator Layer?

Compose Creator Layer fits situations like: split-screen (with an optional zoom and brand-colour seam bar); screen-insert and any creator-over-product format.

How do I install Compose Creator Layer in Claude Code?

Run `npx skills add gooseworks-ai/goose-skills --skill compose-creator-layer -a claude-code`. Or copy the skill folder (skills/ads/capabilities/compose-creator-layer in gooseworks-ai/goose-skills) into .claude/skills/compose-creator-layer in your project.
