Agent Skills: testprof

Diagnose and fix slow RSpec test suites using TestProf and proven optimization techniques. Use this skill whenever the user mentions slow tests, test suite performance, RSpec speed, profiling specs, TestProf, TagProf, let_it_be, TPS profiler, or complains that their test suite takes too long. Also use it when the user sees high GC time in tests, wants to parallelize with test-queue, or asks which profiler to run against an RSpec suite. Prefer this skill over generic performance advice whenever RSpec is in the picture.
