What iterm2-tab-status runs automatically, and when. A hook is a command Claude Code fires at a fixed moment, without you asking for it.
What fires, and when
SessionStart
Fires once when a session begins, and again after a context compaction. It is where a plugin sets up its environment, or restores state the compaction dropped.

AskUserQuestion${CLAUDE_PLUGIN_ROOT}/scripts/hook.shStop
${CLAUDE_PLUGIN_ROOT}/scripts/hook.shUserPromptSubmit
Fires before Claude sees each prompt you send. A plugin can use it to inject context, so the same instruction reaches the model every turn instead of only at session start.

See what every Claude Code session is doing. Each iTerm2 tab shows a status prefix. ⚡ running, 💤 idle, or 🔴 needs attention (with flashing).
Stars on GitHub
A skill that shapes Claude Code's output for readers with ADHD: it leads with the next action, numbers multi-step work, restates state across turns, drops tangents, gives specific time estimates, and makes progress visible. Invoke it with /i-h.

@agenticnotetakingA Claude Code workflow plugin that learns from your corrections and keeps a self-correcting memory across sessions. It adds skills for agent teams, parallel worktree batch changes, bug capture as GitHub issues, project auto-setup and context compaction.
@rohitg00Helps you learn any topic with a first-principles curriculum, guided tutoring, and spaced review that schedules free-recall practice. Includes coaching for retention stats and study strategy.
