Security audit

Agent Soul Sync

Security checks across malware telemetry and agentic risk

Overview

This skill does what it says: it uploads user-selected local OpenClaw skill files to a Mysta cloud agent, with disclosed API-key and network use.

Install only if you trust Mysta and intend to copy local skills to a cloud agent. Before syncing, review the listed SKILL.md files, avoid choosing all if any skill may contain private instructions or secrets, verify the MCP URL is a Mysta endpoint, and use a revocable scoped API key if available.

Finding
This code uploads the full contents of selected local SKILL.md files to a remote Mysta service. Even with stated user consent, it creates a real exfiltration path for any sensitive data accidentally stored in those files, and the optional MYSTA_MCP_URL override increases risk if an attacker can influence the environment to redirect uploads to an untrusted server.
