property-tax-appeal-kit
Security checks for vulnerabilities and agentic risk
Overview
This skill provides local property-tax appeal calculations and guidance without accessing accounts, transmitting data, or filing appeals automatically.
Suitable for local calculations and preparation. Verify filing deadlines, assessment rules, and valuation assumptions with your assessor before relying on the results. The timeline defaults to 30 days and uses fixed milestones; it does not validate your jurisdiction's requirements.
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
