Buildkite Test Engine
This skill should be used when the user asks to "split tests across machines", "set up test splitting", "parallelize test suite", "detect flaky tests", "quarantine flaky tests", "configure test collectors", "speed up tests", "set up bktec", "configure test engine", or "reduce flaky test failures". Also use when the user mentions bktec, Test Engine, test suites, BUILDKITE_TEST_ENGINE_* environment variables, BUILDKITE_ANALYTICS_TOKEN, test-collector plugin, test reliability scores, test timing data, or asks about Buildkite test splitting and flaky test management.
