GitHub Actions Incident Timeline Audit

Security checks for vulnerabilities and agentic risk

Overview

This skill is a local GitHub Actions failure-reporting utility whose file reads and script execution match its stated CI incident-audit purpose.

Install only if you are comfortable running a local bash/python script over GitHub Actions JSON exports. Review RUN_GLOB before use so it does not scan unrelated local JSON files, and use FAIL_ON_CRITICAL only when you want the script to fail CI on critical incidents.

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
