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.

Security Skills for CLI Agents A collection of security testing skills built from analyzing 4,000+ paid HackerOne bug bounty reports. These skills can be used with Claude Code, Gemini CLI, or any agent that supports MCP/Skills. What is this? This repo contains specialized prompts (skills) that teach AI coding agents how to find real security vulnerabilities.
These tools work well together with security-skills 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.
