Work History

March 2026

37 Commits • 17 Features

Mar 1, 2026

March 2026 was a strong sprint across All-Hands-AI/agent-sdk, All-Hands-AI/OpenHands, and All-Hands-AI/docs, delivering measurable business value through feature delivery, reliability improvements, and better governance. Key features shipped improved PR risk governance, runtime configurability for plugins/skills, and public API exposure, while API stability and OpenAPI tooling were hardened to reduce risk for downstream integrations. The work reduced deployment risk, improved developer experience, and set the foundation for safer API evolution and clearer deprecation policies.
