Context Builder

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent wrapper for a code-context CLI, with disclosed file-reading behavior and one supply-chain hardening issue in its install instructions.

Before installing, prefer pinning the documented version, for example with --version 0.8.3 and --locked if supported, and verify any downloaded binary against a version-specific checksum. Use the tool only on explicit project directories and review generated context files before sharing them because they may include secrets from source files.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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
