Sunday

Security checks across malware telemetry and agentic risk

Overview

This skill transparently gives an agent its own Sunday email inbox and encrypted credential vault, with sensitive but disclosed access that matches its purpose.

Install only if you are comfortable giving the Sunday CLI ongoing access to an agent-owned inbox and credential vault. Verify the Homebrew tap and Sunday service before use, protect ~/.sunday/config.json like a password vault, and avoid letting agents print decrypted passwords, OTPs, or verification links unless the task specifically requires it.
