Security audit

bug-pattern-diagnosis-en

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent bug-triage skill that uses a local case library and diagnostic examples, with no hidden execution, persistence, or exfiltration behavior found.

Install only if you want an English markdown-based troubleshooting workflow. When following its diagnostic examples, use non-production or low-risk requests where possible, avoid exposing real tokens unnecessarily, and confirm before letting the agent save new case notes.

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
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Natural-Language Policy Violations

Medium

Confidence
96% confidence
Finding

The manifest-style header names the skill "bug-pattern-diagnosis-en," which indicates an English-only locale constraint. There is no accompanying language choice, opt-in, or justification that the skill is region- or language-specific, so this appears to violate the language/locale policy criteria.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
91% confidence
Finding

The activation guidance includes a broad catch-all trigger for 'intersection / intermittent / non-deterministic' issues, which can cause the skill to activate for a wide range of unrelated bug reports. In an agent setting, over-broad routing is risky because it may steer users into this skill's case-library workflow unnecessarily, increasing the chance of irrelevant file access, noisy diagnosis, or misleading troubleshooting based on weak symptom similarity.

External Transmission

Data Exfiltration
Confidence
60% confidence
Finding

Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
