Expand the pixel-art skill from 2 presets (arcade, snes) to 14 presets with hardware-accurate palettes (NES, Game Boy, PICO-8, C64, Apple II, MS Paint, CRT mono), plus a procedural video overlay pipeline. Ported from Synero/pixel-art-studio (MIT). Full attribution in ATTRIBUTION.md. What's in: - scripts/palettes.py — 28 named RGB palettes (hardware + artistic) - scripts/pixel_art.py — 14 presets, named palette support, CLI - scripts/pixel_art_video.py — 12 animation scenes (stars, rain, fireflies, snow, embers, lightning, etc.) → MP4/GIF via ffmpeg - references/palettes.md — palette catalog - SKILL.md — clarify-tool workflow (offer style, then optional scene) What's out (intentional): - Wu's quantizer (PIL's built-in quantize suffices) - Sobel edge-aware downsample (scipy dep not worth it) - Atkinson/Bayer dither (would need numpy reimpl) - Pollinations text-to-image (Hermes uses image_generate instead) Video pipeline uses subprocess.run with check=True (replaces os.system) and tempfile.TemporaryDirectory (replaces manual cleanup).

### What was ported
|
|
|
|
**`scripts/palettes.py`** — the `PALETTES` dict containing 23 named RGB
|
|
palettes (hardware and artistic). Values are reproduced verbatim from
|
|
`scripts/pixelart.py` of pixel-art-studio.
|
|
|
|
**`scripts/pixel_art_video.py`** — the 12 procedural animation init/draw pairs
|
|
(`stars`, `fireflies`, `leaves`, `dust_motes`, `sparkles`, `rain`,
|
|
`lightning`, `bubbles`, `embers`, `snowflakes`, `neon_pulse`, `heat_shimmer`)
|
|
and the `SCENES` → layer mapping. Ported from `scripts/pixelart_video.py`
|
|
with minor refactors:
|
|
- Names prefixed with `_` for private helpers (`_px`, `_pixel_cross`)
|
|
- `SCENE_ANIMATIONS` renamed to `SCENES` and restructured to hold layer
|
|
names (strings) instead of function-name strings resolved via `globals()`
|
|
- `generate_video()` split: the Pollinations text-to-image call was removed
|
|
(Hermes uses its own `image_generate` + `pixel_art()` pipeline for base
|
|
frames). Only the overlay + ffmpeg encoding remains.
|
|
- Frame directory is now a `tempfile.TemporaryDirectory` instead of
|
|
hand-managed cleanup.
|
|
- `ffmpeg` invocation switched from `os.system` to `subprocess.run(check=True)`
|
|
for safety.
|
|
|
|
### What was NOT ported
|
|
|
|
- Wu's Color Quantization (PIL's built-in `quantize` suffices)
|
|
- Sobel edge-aware downsampling (requires scipy; not worth the dep)
|
|
- Bayer / Atkinson dither (would need numpy reimplementation; kept scope tight)
|
|
- Pollinations text-to-image generation (`pixelart_image.py`,
|
|
`generate_base()` in `pixelart_video.py`) — Hermes has `image_generate`
|
