Security checks across malware telemetry and agentic risk

Overview

This is a documentation-only Claude Code internals skill with no executable installer, hidden data access, or runtime automation.

Reasonable to install as a technical reference. Read the permission examples critically, especially the allow-by-default snippet, and independently verify security-sensitive tool or hook designs before copying them into real code. Expect the content to be mostly Chinese.

Intent-Code Divergence

Medium
Confidence
94% confidence
Finding
The document explicitly labels the defaults as 'fail-closed', but the shown implementation includes `checkPermissions: ... => ({ behavior: 'allow', ... })`, which is allow-by-default. In a security-sensitive tool framework, this mismatch can mislead developers into relying on protections that are not actually present, increasing the chance that new tools ship without meaningful permission enforcement.

Vague Triggers

Medium
Confidence
83% confidence
Finding
The skill advertises broad trigger scenarios such as general architecture analysis, debugging, and extension development, which can cause over-activation outside narrowly intended contexts. Overly broad matching can inject large amounts of internal guidance into unrelated sessions, increasing prompt-surface area, confusing agent behavior, and potentially biasing security-relevant decisions when the skill is auto-selected.

Natural-Language Policy Violations

Medium
Confidence
71% confidence
Finding
The skill description indicates a Chinese-only interaction model without offering language negotiation or fallback behavior. This can cause misunderstandings, incorrect tool use, or misinterpreted safety guidance for users operating in other languages, which is a reliability and safety concern even if not a direct exploit primitive.
