The quality score combines nine heuristic checks of the repo and its README: completeness, clarity, specificity, examples, structure, agent readiness, step-by-step content, instruction quality and security notes. It rates how well the project explains itself to an agent, not the code.

About cmux

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.

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy: 42 published rules, covering credential harvesting, data exfiltration, curl | sh installers and more. 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.
