May 1, 2026May 2026 monthly summary for aws/language-servers. This period focused on delivering end-to-end HITL (human-in-the-loop) workflow improvements and expanding workspace/build verification capabilities, while stabilizing visibility of HITL events across all job states and enhancing developer tooling with a chatty agent and richer workspace metadata. The work aligns with the goal of accelerating verification cycles, improving quality in customer-ready changes, and enabling more reliable, observable HITL surfaces in IDEs and dashboards.
