Coloring Book Skill — AI skill for Claude Code

coloring-book — a Claude Code skill for personalized kids' coloring books

Give it your kids' names, hair, glasses, freckles, pets, and favorite things — get back a printable, letter-size vector PDF coloring book starring them. Themed pages ("their favorite things") or **story mode** for ages 3-6 (a gentle 10-beat quest with captions built for pre-readers: simple present tense, name repetition, a chant-along refrain).

*The bundled example, "Where Is Button?" — a fictional family's teddy-bear hunt, built end-to-end by the skill.*

Why it works (design choices)

• Parametric characters, not AI likeness. Each child is a small trait vector (hair silhouette, glasses, freckles, height, a personal motif). Same recognizable kid on every page, zero identity drift, no photos needed or wanted.
• Everything is bold vector line art (SVG → PDF), tuned to age-band line weights. No diffusion raster output, no broken gray lines.
• A shape library instead of freehand geometry. LLMs reliably botch bicycles and side-view cars; the skill ships 200+ object helpers indexed by interest in `reference/catalog.md` — vehicles, trains, boats, space, farm and wild animals, buildings, playground gear, people in run/jump/point/carry/sleep poses, a wheelchair user — plus relative-proportion recipes for anything else (derived from public-domain 1910s drawing pedagogy and MIT-licensed icon skeletons — see CREDITS.md).
• Scene kits and a composition recipe. lib/scenes.py gives proven backgrounds (meadow, street, beach, space, farm) with declared ground lines; the drawing guide's three-layer recipe (background kit → midground anchor → foreground figures at 300-380 px) is what keeps pag
