jobctl is a read-only query tool for discovering and inspecting running Claude Code sessions ("jobs"). It has two commands: list-jobs and show-job.
jobctl reads from a single SQLite database: ~/.local/state/claude/hooks-tracker.db. This database is populated by Claude Code's hook system (via hookctl), not by jobctl itself. jobctl never writes to it.
Key tables:
jobs— job_id, name, created_at, tmux coordinates, state
