happier-profile-and-optimize
happier-profile-and-optimize is a Mobile performance & profiling skill for AI agents, published by happier-dev in the happier repository on GitHub. Skillspace rates happier-profile-and-optimize D (68/100) and it passed the safety scan; the rating is based on static analysis only.
The method for profiling and optimizing anything whose success is a measured cost — frame the phase and metric, choose an instrument that can actually see the cost, label the waste, falsify the hypothesis with a cheap control before building a fix, and prove the result without over-claiming. Covers app/device and server/database work. Use when work is about slowness, jank, startup/open time, blocked JS, hangs, memory, render churn, a slow query, or a claimed speedup. It does not carry the write-time gotchas for UI code — those live in `apps/ui/AGENTS.md`.
