1. Awesome Claude Code

Status Lines / Obsidian

• TermaGITchi (⭐12) by TevvvB - A Go CLI that gives each Claude Code session its own creature in the status line, derived by hashing the session id, with one den per git worktree. Where other status-line faces react to what the agent is doing, this one is a stable identity for telling parallel sessions apart, and its expression tracks repository hygiene: uncommitted files, unpushed commits, distance behind trunk and the last test result.\       

• tmux-claude-status-tabs (⭐2) by LiveNL - Shows each Claude Code session's state in the tmux tab bar, per window: an animated spinner while it works, amber when it waits on input, red on a permission request, green when done. Event-driven via hooks with no polling; catches unreported transitions (Esc, permission grants, stop-hook continuations) with transcript watchers. 260+ test assertions run in CI.\
