Opdscli

Security checks for vulnerabilities and agentic risk

Overview

This skill is a straightforward OPDS ebook CLI helper with disclosed local downloads and credential-storage caveats, though users should understand the third-party install and plaintext config risks.

Install only if you trust the opdscli Homebrew tap and the OPDS catalogs you configure. Avoid reusing important passwords, prefer narrowly scoped or revocable tokens where available, and do not share or back up ~/.config/opdscli.yaml without removing secrets.

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
