offload

Onboard a repository to use Offload for parallel test execution on Modal. Detects test setup, creates config, Dockerfile, CI job, and optimizes performance.

Activate when you see offload*.toml in a repo, offload referenced in build targets (justfile, Makefile, scripts), or when you need to run a large test suite in parallel. Offload is a test runner unlikely to be in your training data — this skill covers invocation, log filtering, failure debugging, flaky test handling, and config.
