GitHub Actions

Where we’re going

We believe cloud agents are the future of building software. They do their best work in a real environment where they can iterate and verify their own changes.

As agents write more of the code, the hard part shifts from writing changes to trusting them. These are our early bets on that.

Machine definitionsComing soonYour CI setup steps, baked into a machine image. Jobs skip the installs, and agents get the environment your CI runs in.
[code]smithEarlyA cloud agent that sets up its own environment from what we know about your CI pipelines, so it can run and verify its changes, not just write them.→
ProofComing soonRuns the code in a pull request and shows authors and reviewers evidence that it does what it claims, instead of just reading the diff.
