Agent Zero is now public — proactive review is here

[RedStar071]

Agent Zero is now open source 🎉

Agent Zero is an autonomous engineer built around one principle: code-review findings should be verified against repository evidence before they are accepted or fixed.

Today the repository is public, and the v0.2 proactive-review foundation is available on main.

What is new in v0.2

• Proactive pull-request review — inspect a PR diff without waiting for reviewer feedback.
• Evidence-backed findings — every finding carries severity, confidence, affected files, and concrete repository evidence.
• Confidence-gated autofix — automatic changes require repository permission, sufficient confidence, an allowed risk class, native checks, and runner isolation.
• Human control for high-impact work — security-sensitive, dependency, schema, CI, test, and policy changes always require approval.
• CLI and webhook support — run locally with zero review --proactive or opt in through repository configuration for GitHub pull-request events.

Safety remains the default: observe mode is read-only, and all repository commands and file mutations stay behind the runner boundary.

Try it locally

mise install
aube ci
cp .env.example .env
aube test
aube run zero doctor
aube run zero review --proactive

The implementation landed in PR #19 and completes issue #9.
