Debug Methodology

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed debugging checklist with no executable payload, hidden persistence, or unrelated data access.

Install this if you want the agent to apply a structured root-cause debugging process broadly. Because it includes server deployment and restart guidance, keep normal approval boundaries for real production changes, backups, pushes, and restarts.

A.I.G

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

Natural-Language Policy Violations

Medium
Confidence
80% confidence
Finding
Most of the user-facing instructional content is written in Chinese, which implicitly fixes the skill's operating language without stating that users may choose another language. Under the language/locale policy, forcing a specific language without opt-in can be a natural-language policy violation.

Session Persistence

```
Confidence
60% confidence
Finding
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Vague Triggers

Medium
Confidence
88% confidence
Finding
The README states that after restart, 'all sessions' encountering a debugging scenario will automatically load this methodology, but it does not define concrete trigger phrases, scope boundaries, or exclusion conditions. For a markdown skill description, this is an ambiguous activation condition that could overlap with many common conversations about debugging.
