bun tools/build-mod.ts # builds ArcMod and puts it in /ApplicationsTaken from the project's README on GitHub. Check the security audit before running it.
None of the 42 rules matched — no credential harvesting, no data exfiltration, no curl-pipe-shell installer. Scanned against 42 published rules built on the SlowMist agent-security taxonomy, refreshed every 8 hours. Full audit →
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.

ArcMod ArcMod is a modified copy of the Arc browser for macOS that you can use without an Arc account. Arc's own services are blocked, it's a little lighter, and coding agents (Codex, Claude Code) get browser tools of their own. Work in progress. This is an experimental mod I use day to day. Expect rough edges. Known problems are tracked in the pinned status issue.
These tools work well together with arc for enhanced workflows:

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.
