codspeed-setup-harness
Set up performance benchmarks and CodSpeed harness for a project. Use this skill whenever the user wants to create benchmarks, add performance tests, set up CodSpeed, configure codspeed.yml, integrate a benchmarking framework (criterion, divan, pytest-benchmark, vitest bench, go test -bench, google benchmark), or when the user says 'add benchmarks', 'set up perf tests', 'create a benchmark', 'benchmark this', or wants to measure performance of their code for the first time. Also trigger when the optimize skill needs benchmarks that don't exist yet.

qa-test-staging
Post-merge QA sweep of staging.compasscalendar.com in the user's real Chrome - select and verify the correct signed-in staging profile (never the localhost/temp-account one), run the standard usage flows as the authed test user watching console/network for breakage, then read the recent merged PRs and exercise their Manual Testing Steps to catch regressions in freshly-touched flows. Use when the user says "/qa-test-staging", "sanity check staging", "test staging", "check staging after deploy", "run the staging sweep", or asks to verify the staging deploy after a PR merged.
