Skill Data Exfiltration via Compound Patterns

Detects compound exfiltration patterns in SKILL.md files where sensitive data (credentials, SSH keys, wallet files, browser data, environment variables) is read AND transmitted to an external endpoint. Single-action patterns (just reading env vars or just mentioning curl) are intentionally excluded to avoid false positives on legitimate security and DevOps skills.
