Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionsigmaExecute the skills CLI command in your project's root directory to begin installation:
Package manager
npx skills add https://github.com/sanyuan0704/sanyuan-skills --skill sigmaFetches sigma from sanyuan0704/sanyuan-skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate sigma. Access via /sigmain your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.
