GitHub Actions Conclusion Volatility Audit
Security checks for vulnerabilities and agentic risk
Overview
This skill is a straightforward local audit tool for GitHub Actions run-history JSON and does not show hidden, persistent, destructive, or data-exfiltrating behavior.
Install this if you are comfortable running a local bash/Python reporting script over GitHub Actions JSON exports. Keep RUN_GLOB pointed only at intended run-export files, and review output before using FAIL_ON_CRITICAL as a CI gate.
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
