arc-shield
About
Arc-shield is an output sanitization skill that scans all agent responses to prevent accidental leaks of secrets, tokens, and PII. It acts as a final filter for sensitive data that an agent might inadvertently include in debugging output, code examples, or file contents. Use this security skill when your agent has access to sensitive resources like vaults or environment variables.
