Security Findings3

Severity	Finding	Layer	Location
CRITICAL	Persistence / self-modification instructions Shell RC file modification for persistence Remove any persistence mechanisms. Skills should not modify system startup configurations, crontabs, LaunchAgents, systemd services, or shell profiles.	Manifest	business-operations/skills/internal-comms/scripts/change_announcement_builder.py:256
CRITICAL	Persistence / self-modification instructions Shell RC file modification for persistence Remove any persistence mechanisms. Skills should not modify system startup configurations, crontabs, LaunchAgents, systemd services, or shell profiles.	Manifest	business-operations/skills/internal-comms/scripts/change_announcement_builder.py:322
HIGH	Unsafe deserialization / dynamic eval Decryption followed by code execution Remove obfuscated code execution patterns. Legitimate code does not need base64-encoded payloads executed via eval, encrypted-then-executed blobs, or dynamic attribute resolution to call system functions.
