extract

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed codebase-knowledge extractor that reads the project and writes a local `.gauntlet/knowledge.json` file, with no evidence of deception, exfiltration, or destructive behavior.

Install only if you want the agent to inspect the selected codebase and maintain a `.gauntlet/knowledge.json` file. Review that generated file before committing it, especially in private or proprietary repositories, because it may summarize sensitive architecture or business logic.

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
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Trigger AbuseOverly Broad Trigger, Shadow Command Trigger, Keyword Baiting Trigger
  • 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
94% confidence
Finding

The trigger condition is very broad: 'initializing or refreshing codebase knowledge for challenges' can plausibly activate during routine repository work without a narrowly scoped user request. Because the skill performs extraction and later writes workspace artifacts, broad activation increases the chance of unintended execution of filesystem-modifying behavior.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The skill instructs the agent to write .gauntlet/knowledge.json and merge annotations without any explicit warning, confirmation step, or safety boundary around modifying project files. In an agent setting, this can lead to silent workspace changes, accidental overwrites, or persistence of AI-generated content into the repository when the user may have expected read-only analysis.
