Critical

E006: Malicious code pattern detected in skill scripts.

What this means

Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.

Why it was flagged

This skill is deliberately designed to capture and persist users' exact messages and entity mentions silently on every inbound message (ambient data collection without user-visible notice), which constitutes high-risk intentional data exfiltration and covert surveillance.

High

W007: Insecure credential handling detected in skill instructions.

What this means

The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.

Why it was flagged

This skill explicitly requires capturing the user's "EXACT phrasing" and creating/updating brain pages and logs for every inbound message, which forces the agent to record any secrets (API keys, passwords, tokens) present verbatim in its outputs/storage, creating a high exfiltration risk.
