cmux — tmux for Claude Code Run a fleet of Claude agents on the same repo — each in its own worktree, zero conflicts, one command each. Claude Code works best when it has full ownership of the working directory. Want two agents working in parallel? They'll stomp on each other — conflicting edits, dirty state, broken builds. You need separate checkouts. Git worktrees are the perfect primitive for this. They share the same database but give each agent its own directory tree — no cloning, no syncing, branches stay in lockstep. cmux wraps the entire worktree lifecycle into single commands so you can spin agents up, jump between them, and tear them down without thinking about it. You wanna go fast without losing your goddamn mind. This is how. Install Then add to your : Quick start That's it. One command, one agent, fully isolated. See Workflow for the full loop. Commands cd

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
