Jrv Text Diff

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward local text-diff helper, with minor hardening issues but no evidence of hidden, destructive, persistent, or data-exfiltrating behavior.

Install only if you are comfortable running a local Python diff script on files you choose. Avoid comparing untrusted files with terminal control characters in a sensitive terminal, and prefer a virtual environment with pinned dependencies if using YAML mode.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
Insecure Skill Coding PracticesFinds exploitable flaws such as hardcoded secrets or command injection
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
