Semantic search over the 60fps library of mobile interaction reference clips. Start here when you have the interaction in words. When the user names one shot and wants more like it ("I like the Flighty connection assistant sheet, find similar shots"), use this only to find that shot's slug, then call 60fps_get_related_shots with it: search results include the named shot itself and are ranked against the words, not against the shot. Returns the best-matching shots (title, app, one-line summary, motion behavior, filters, intensity, mood, and video/poster/page URLs). Use natural language, e.g. 'springy bottom sheet for checkout' or 'calm premium onboarding'. Optionally narrow by filter slugs, app (slug or name), or platform. Filters are exact and results must have ALL of them, so an unknown slug returns nothing: leave `filters` empty unless you took the slugs from a result's `filters`. An `app` that is not in the library is ignored and flagged in `notice`. Read-only; results capped at 20. `total` is how many shots were searched, not a match count: results are the closest by meaning, so always judge them on their own merits rather than assuming a high count means a good match. DO NOT CALL for: Android, Material Design, Flutter or web, since this library is iOS only and will still return iOS shots; generating or critiquing a design (icons, colour palettes, logos, brand), since this searches recordings of shipped apps and cannot design anything; or performance, profiling and frame-rate debugging, which share the name 60fps and nothing else. For any of those, answer directly and do not call this tool.
