skull-studylisted

Render an animal HEAD as a skull-shape turntable — an azimuth sweep (front → ¾ → lateral → back) plus top-down and under views, cropped to the head — so a skull reads correctly from EVERY angle, not just one. Catches the failure modes a single view hides (a hollow/open-tube face that only shows head-on, a pale interior scoop that only shows at ¾, a lopsided or over-long muzzle that only shows from above). Use before/after tuning any animal head, when adding a new species' skull, or after editing the skull/welded-head builders (figure-animal-skull.js, weldedSkull in figure-animal-skin.js). Invoke as `/skull-study <species|archetype>` or `/skull-study --recipe head.json`.

# skull-study The head is the hardest part of an animal to get right, and the part a single render lies about most. This is the **check pass for skull shape**: it renders a head from all around so you can Read the turntable and catch what a front-only or lateral-only view hides. Why a turntable and not one view — learned the hard way on the leopard head: - the **hollow / open-tube face** (a short-muzzled skull with no front cap) reads fine in profile but is a see-through ring head-on; - the **pale interior scoop** (looking into the open muzzle) only appears at ¾; - an **over-long, lopsided, or wrongly-dropped muzzle** only reads from top / under. ## Use it ```bash node .claude/skills/skull-study/study.mjs <subject> [<subject>...] [--recipe file.json] [--out dir] ``` Then **Read the printed PNGs** — that is the analysis. Each subject writes a turntable to `<out>/<subject>/png/` (default `/tmp/skull-study`): | view | reads | |---|---| | `1-front` | face plane — hollow ring? eyes/nose seated? countershade chin? | | `2-front3q` · `3-threeqtr` | the recognizability angle — muzzle mass, cheek fill, scoop | | `4-lateral` | profile — muzzle length, brow/stop, nasal bridge, jaw | | `5-rear3q` · `6-back` | cranium closure, ear seating | | `7-top` | dorsal skull, muzzle centering + symmetry, **nasal bridge prominence** | | `8-under` | muzzle / jaw underside, chin | Subjects: - **a species** — any `ZOO_BUILDS` key (`wolf`, `cougar`, `lion`, `deer`, `fox`, …). - **an archetype**
