Security checks across malware telemetry and agentic risk

Overview

This is an instruction-only skill for locally saving user-provided personality notes and simulated responses, with privacy-sensitive but disclosed behavior.

Install only if you are comfortable keeping local plain-text notes about real people on your device. Avoid saving private or sensitive details, periodically delete profiles you no longer need, and do not present generated responses as if they came from the real person.

Vague Triggers

Medium
Confidence
94% confidence
Finding
The trigger 'You describe a bro -- stories, memories, how they talk' is broad enough to overlap with ordinary conversation and does not clearly define when the skill should activate versus when a user is just chatting. The file also does not provide exclusion conditions or negative examples to constrain activation.

Vague Triggers

Low
Confidence
84% confidence
Finding
The trigger 'Simulate a conversation with multiple profiled bros' describes a capability rather than a precise activation phrase or constrained condition. Without explicit trigger wording or scope limits, it is unclear what exact user inputs should invoke this mode.
