Agent Credential Vault - Anima

Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed credential-vault workflow that helps agents use stored credentials without exposing raw secrets, with sensitive behavior aligned to its stated purpose.

Install only if you intend to use Anima as a trusted credential broker. Prefer brokered reveal policy, set allowed hosts for API keys, use dry-run before subprocess injection, and avoid granting agents credentials that can make purchases, delete data, or change accounts without separate human approval.

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
