AANA Calendar Scheduling Guardrail Skill
Security checks for vulnerabilities and agentic risk
Overview
This instruction-only skill adds conservative checks before calendar changes and does not install code, run commands, persist data, or access calendars on its own.
This is reasonable to install as a calendar-safety guardrail. If you connect it to an AANA checker, make sure that checker is one you trust, because even redacted meeting-risk summaries can reveal some context about planned calendar actions.
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
Vulnerability Patterns
- Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
- Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
- Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
- Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
- Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
