Without declared permissions the skill's intent is opaque and cannot be validated.
SKILL.md
Code accesses environment variables that may contain secrets (API keys, tokens). This is a common pattern for credential theft.

Model output is used without validation or sanitization. Unvalidated output injected into downstream contexts (SQL, shell, HTML) enables injection attacks and arbitrary code execution.

Tool defaults are unsafe or overly permissive (e.g. disabled TLS verification, no authentication, world-writable permissions). Unsafe defaults widen the attack surface.
