Denied Claim Appeal Drafter
Security checks for vulnerabilities and agentic risk
Overview
This skill is a narrowly scoped medical-claim appeal drafting guide that emphasizes human review, PHI minimization, and no appeal submission by the agent.
Before installing, users should be aware this skill is intended for sensitive healthcare billing workflows and may involve PHI, claim identifiers, and chart excerpts. Use only minimum necessary data, verify payer deadlines and policy citations, and keep the generated appeal as a draft for qualified biller, coder, or clinician review before any submission.
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
