This skill appears to be what it says: a local, fast email-format checker and simple heuristic risk scorer. It does NOT perform DNS/MX lookups, SMTP verification, or deliverability checks — do not rely on it for final deliverability decisions or security-critical verification. The disposable/free-domain lists and risk formula are small and heuristic; if you need production-grade email validation (MX checks, SMTP probing, or a more comprehensive disposable domain list), use a specialized service or add those checks yourself. Review whether the heuristic scoring aligns with your policy before auto-blocking users based solely on this score.

Type: OpenClaw Skill Name: validate-email Version: 1.0.1 The skill performs local email validation and risk scoring as described in the documentation. The implementation in handler.ts uses standard regular expressions and hardcoded lists for disposable domain detection, with no external network calls, file system access, or suspicious dependencies. The logic is transparent and aligns perfectly with the stated purpose of providing a privacy-focused, local validation tool.
