May 1, 2026

May 2026 was focused on establishing a multi-agent hosting foundation, boosting developer productivity across shells and editors, and hardening CI workflows. Key deliverables included the Port Registrar foundation with dynamic ports, per-session registrations, and a discovery channel to support multiple agents in a single process, plus a discoverPort helper for runtime lookups. Shell IntelliSense received targeted improvements and demo polish, including per-prefix completion, enhanced Enter/Tab behavior, and a new API to force fresh data fetches. The TypeAgent chat panel for VS Code was delivered with multi-panel session sharing, persistent history, and polished reconnect/cancel UX, aligning VS Code and Electron shells. The Port Registrar gained a system ports command for live introspection of registrations and client counts, and browser agent migrations to dynamic ports with origin gatekeeping (plus a C# discovery client). CI workflows were hardened to improve dependabot remediation, including install-once optimization, failure surfacing, and clear noPatch tracking, reducing toil and accelerating remediation momentum.
