"One-directional knowledge bridge from Google Antigravity IDE to OpenClaw. Syncs only .md documentation files from Antigravity projects into OpenClaw workspace for native vector indexing. No secrets, credentials, or binary state are synced — rsync filters enforce .md-only transfer. Supports multiple projects."

🔒 Containment

Level: maximum

Required:

SANDBOX_CONTAINER: Code execution capability

Recommended:

LOG_ACTIONS: Audit trail for all actions

⚡ Risks

Unauthorized tool use: MCP_SYS_CRITICAL_ACCESS, INSTRUCTED_BINARY_INSTALL high

Mitigation: Avoid accessing system directories unless absolutely necessary.

Command injection risk: COMMAND_INJECTION_USER_INPUT, TIRITH_DOTFILE_OVERWRITE high

Mitigation: Validate and sanitize all user inputs before using in commands

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality

Tool poisoning: hidden behaviors detected (MCP_TOOL_POISONING_REMOTE_STORAGE) medium

Mitigation: Document all remote data storage. Avoid storing sensitive data externally.
