S2G - General Purpose Workflow Engine

· v1.0.0

Low Risk

Connect to S2G (s2g.run) visual workflow automation platform over WebSocket. Execute workflow nodes as tools — password generators, hash functions, date math, format converters, database queries, knowledge base, and any custom node. Use when asked to run S2G workflows, execute S2G nodes, connect to S2G, manage S2G workflows, or interact with the S2G platform API.

🔒 Containment

Level: maximum

Recommended:

LOG_ACTIONS: Audit trail for all actions

⚡ Risks

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION, SOCIAL_ENG_ANTHROPIC_IMPERSONATION low

Mitigation: Provide clear, detailed description of skill functionality

Data exfiltration patterns: MCP_EXFIL_EXTERNAL_UPLOAD high

Mitigation: Document all external data transfers. Remove suspicious upload references.
