Engrm Delivery Review

Security checks for vulnerabilities and agentic risk

Overview

This skill is a scoped delivery-review guide that uses Engrm only when available and discloses its limited memory-writing behavior.

Install only if you want agents to use Engrm for delivery-review history. Expect it to write concise review memories about outcomes, gaps, and lessons when Engrm is available.

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

Memory Manipulation

High

Category: Memory Poisoning
Confidence: 80% confidence
Finding: Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.
