Aether

We don’t talk enough about code review and it’s probably why everyone’s doing it wrong.

Having another agent review your PR is a meaningless rubber stamp. Even if you use a different model, a reviewer agent reads code, but it doesn't run it. Two agents agreeing is not evidence of anything.

If you truly want it verified the only way is an isolated devbox with real tests, previews, and logs. If you’re a serious developer get serious about review.

this is why Aether was built

Aether has the best computer use tools of any platform. The agent gets tools to test its changes in a browser, terminal, desktop app, or iOS or Android mobile device

A reviewer that reads your diff gives you an opinion.

A reviewer that runs your code gives you a screenshot of the thing that broke.

We built the second one.

The 4 things that make up the best coding setup right now:

Claude Code as the harness.

Astra for adversarial review.

Environment config committed to the repo.

One machine per agent on a cloud devbox.

The thing nobody tells you about running agents in parallel: you just end up wasting time verifying it.

Let’s say you split a feature four ways. Migration, API, UI, tests. Four agents, four branches, all running at once.

Minute 20: the migration agent adds a role enum it didn't originally plan.

Minute 21: the API agent is still building against the schema you described before that existed.

Minute 35: the UI agent stalls on a permission prompt nobody is watching.

Minute 50: the test agent decides the feature is broken and starts "fixing" working code.

Minute 75: you find all of this at merge.

The generation was in parallel but the coordination wasn’t. Parallelism isn't the hard part anymore. Keeping four agents working from the same set of facts is.
