Show HN: Buddylist – Coding agents in an MSN-style messenger

A developer released Buddylist, an MSN-style messenger desktop app that runs coding agents such as Claude, Codex, Gemini and OpenCode as contacts in a project folder. Buddylist gives each contact its own git worktree and branch, lets multiple agents take turns or answer at once in a shared chat via @mention, and replaces terminal permission prompts with Accept, Always allow or Decline invitations. The app also adds a Changes tab with side-by-side diffs and reviewer threads, a Browser tab for localhost:3000, a Subagents tab with per-subagent Stop controls, and status-bar bars for context window and plan session and weekly limits.
