Security audit

Gdb

Security checks for vulnerabilities and agentic risk

Overview

This skill appears low-risk to your system, but it should be reviewed because it claims to be a GDB reference while only providing generic placeholder guidance.

Install only if you understand this is effectively a placeholder/template, not a real GDB reference. It does not appear to steal data or modify the machine, but users should not rely on it for debugging decisions until the publisher replaces the boilerplate with accurate GDB-specific material or renames the skill to match its actual behavior.

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

MCP Tool Poisoning
Confidence
98% confidence
Finding

The declared description says this is a 'Gdb reference tool' for working with gdb in devtools contexts. However, the code only prints generic canned text with broad sections like performance, security, and migration, and contains placeholder descriptions such as 'Gdb (gdb) is a specialized tool/concept in the devtools domain.' There is no actual GNU Debugger reference content, command lookup, integration, or behavior specific to gdb. The script is harmless and does not access resources or use hidden triggers, but its primary purpose as implemented does not accurately match the declared description.

Credential Access

Confidence

Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Description-Behavior Mismatch

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The script advertises itself as a GDB reference tool, but the content is generic placeholder text unrelated to GNU Debugger. This mismatch can mislead users and downstream agents into trusting inaccurate guidance, causing unsafe debugging decisions or operational errors in a devtools context.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The inline documentation and command help present authoritative GDB guidance, but the implementation only emits generic boilerplate. In an agent skill ecosystem, deceptive or inaccurate documentation can create a supply-chain trust issue by causing users or agents to rely on false expertise.
