skillcheck\n\nScan your machine for malicious AI agent skills in seconds.\n\n```bash\nnpx @mondoohq/skillcheck\n```\n\n![skillcheck demo](demo.gif)\n\nskillcheck detects locally installed AI agent skills, computes SHA-256 checksums, and checks them against the [Mondoo AI Agent Security](https://mondoo.com/ai-agent-security) database — covering prompt injection, credential theft, data exfiltration, and 25+ other threat categories across 1,200+ known skills.\n\n## Supported Agents\n\n| Agent | What's Detected |\n|-------|-----------------|\n| [Claude Code](https://docs.anthropic.com/en/docs/claude-code) | skills, plugins, MCP servers |\n| [OpenAI Codex](https://openai.com/index/introducing-codex/) | skills, plugins, MCP servers |\n\nMore agents (Cursor, GitHub Copilot, Goose, Gemini CLI, Windsurf, Zed) are coming soon.\n\n## Usage\n\n```bash\n# Scan all detected agents\nnpx @mondoohq/skillcheck\n\n# JSON output for CI/CD pipelines\nnpx @mondoohq/skillcheck --json\n\n# Verbose output with full hashes and report URLs\nnpx @mondoohq/skillcheck --verbose\n```\n\n### CI/CD Integration\n\nskillcheck exits with code **1** when critical or high-risk skills are found, making it easy to use as a gate:\n\n```yaml\n# GitHub Actions\n- run: npx @mondoohq/skillcheck\n```\n\n```bash\n# Any CI pipeline\nnpx @mondoohq/skillcheck --json --no-color\n```\n\n### Other Install Methods\n\n```bash\n# Install globally via npm\nnpm i -g @mondoohq/skillcheck\n```\n\nBinaries for macOS, Linux, and Windows are also available on [GitHub Releases](https://github.com/mondoohq/skillcheck/releases).\n\n## What Gets Checked\n\nFor each detected agent, skillcheck:\n\n1. Discovers installed skills, plugins, MCP servers, and rules\n2. Computes a SHA-256 content hash for each skill\n3. Queries the [Mondoo skill database](https://mondoo.com/ai-agent-security/skills) for known threats\n4. Reports findings with severity, summary, and a link to the full security report\n\nSkills that aren't in the database yet show as clean — skillcheck fails open, never blocks your workflow.\n\n## Links\n\n- [Mondoo AI Agent Security](https://mondoo.com/ai-agent-security)\n- [Skill Database](https://mondoo.com/ai-agent-security/skills) — browse 1,200+ analyzed skills\n- [Security Checks](https://mondoo.com/ai-agent-security/checks) — 25+ threat categories\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmondoohq%2Fskillcheck","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmondoohq%2Fskillcheck","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmondoohq%2Fskillcheck/lists"}
