qa-bug-root-cause-analysis

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent bug root-cause-analysis skill with disclosed troubleshooting guidance and no hidden persistence, exfiltration, or destructive behavior found.

Install this only if you want a Chinese-language QA root-cause-analysis helper. Avoid pasting real production logs, customer data, payment details, identity numbers, or screenshots unless they are masked. Treat the optional `npx skills add Kokxi/qa-test-skills` command as a separate trust decision and verify the source before running it.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The trigger list includes generic phrases such as “定位问题” and “排查方向,” which are common in everyday troubleshooting and not specific to root-cause-analysis workflows. The description does not provide exclusion conditions or negative examples, so it is unclear when this skill should activate versus more general debugging or bug-reporting skills.

Vague Triggers

Confidence
90% confidence
Finding

The metadata repeats broad activators like “定位问题,” “排查方向,” and “需要分析Bug根因,” but does not define required context such as recurrence, post-incident analysis, or systemic improvement goals. This can cause accidental invocation for routine debugging requests that are outside the intended scope.

Finding

The skill instructs users to install a package via npx skills add Kokxi/qa-test-skills without pinning an exact version or integrity, which creates a supply-chain risk. If the referenced package or its transitive dependencies are updated maliciously or unexpectedly, users may execute unreviewed code during installation or use.

Natural-Language Policy Violations

Confidence
91% confidence
Finding

The document content and usage instructions are entirely in Chinese, and it does not indicate that other languages are supported or that Chinese is required for a specific regional or compliance reason. Under the policy, language constraints should be optional or explicitly justified rather than implicitly enforced.
