wasm-boot-profiling
wasm-boot-profiling is a Web performance & accessibility skill for AI agents, published by aim2bpg in the rubree repository on GitHub. Skillspace rates wasm-boot-profiling F (45/100) and the safety scan rated it risky; the rating is based on static analysis only.
Risky. This skill has patterns associated with unsafe behaviour. Read the source carefully before running it.
How to measure where time goes during Rubree's WASM Rails boot sequence (Service Worker → ruby.wasm), and what we already learned from one full measurement pass — gem require + Rails.application.initialize! + WASM compile dominate (~99%), while the ActiveRecord DB adapter (sqlite3_wasm vs nulldb) is negligible (~1.5%). Use when investigating "WASM load is slow", "the page freezes on iOS/mobile while loading", or when considering swapping the DB adapter to speed up boot — measure first, this skill shows how and what was already found.
