What is wrsmith108/varlock-claude-skill?
VarLock is an open-source skill designed for secure environment variable management when using Claude. It ensures that secrets remain protected and are never exposed in Claude sessions, terminals, logs, or git commits.
The skill integrates directly with Claude to handle variables safely without altering standard development processes. Users benefit from automatic safeguards that reduce the risk of accidental leaks.
