Motion work beyond a single animation, prompted by a read of Emil Kowalski's skills (MIT) as presented on aiforui.dev. Each idea is folded into an existing skill; no skill was added.

• web-design motion gains a short effect vocabulary for vague requests, choreography roles for several elements moving at once (one lead, followers 30-80ms behind, named still elements, exits together and faster), and a whole-app motion audit: an inventory with file:line, keep, fix or cut by frequency and purpose, a default cut list, the missing motion, and self-contained change items. Motion reviews end with approve, approve with fixes, or block.
• web-design prototypes two or three variants behind a development-only switch when two directions both survive the generic test, and uses a maintained headless library (or the project's primitive) for toasts, drawers, comboboxes, date pickers, virtualised lists and drag and drop instead of hand-rolling them.
• The craft floor adds absolute dates after about a week, Intl.PluralRules and Intl.NumberFormat for counts, and eased multi-stop edge fades.
• catalog.json carries a stage, the skills each one pairs with and example prompts, checked by bun run validate. The new skills directory at andrewwilkinson.io/skills is built from it.
• README and installation docs add the npx skills add ADWilkinson/astack route, which the skills CLI already resolves to all eleven skills.
• Two routing eval cases for app-wide motion audits and choreography.
