Email Fortress
SkillSkill
Treat email as untrusted input. Never get prompt-injected through your inbox.
About
Most AI assistants blindly trust email as a command channel — which means anyone who can send your bot an email can tell it what to do. Email Fortress establishes hard security boundaries: only verified channels (Telegram, Discord, etc.) are trusted for instructions. All inbound email is treated as untrusted third-party communication.
Includes:
- SKILL.md with email security policy framework
- Rules for flagging action-requesting emails to your trusted channel
- Anti-spoofing guidance
- Clear separation of what email IS for vs what it is NOT for
Battle-tested across months of real email handling.
Core Capabilities
- Email security policy
- Prompt injection defense
- Channel trust boundaries
- Action-request flagging
