Security checks for vulnerabilities and agentic risk

Overview

This skill is a disclosed literature-review workflow that searches locally, sends minimized paper evidence to a paid cloud screener only after confirmation, and uses local helper scripts for validation and Excel output.

Before installing, be comfortable using the LoomLoom CLI and sending minimized paper evidence to the selected third-party cloud platform for a per-paper fee. Do not include personal details or credentials in handoff records, and require a fresh confirmation before every paid run.

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
  • Excessive AgencyUnrestricted Tool Access, Autonomous Decision Making, Scope Creep
  • MCP Least PrivilegeUnderdeclared Capability, Wildcard Permission, Missing Permission Declaration
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

MCP Least Privilege
Confidence
97% confidence
Finding
The skill requires broad local file read/write behavior via helper scripts and generated artifacts, but it declares no explicit tool scope or allowed-tools boundary. That omission weakens least-privilege controls and makes it easier for an agent runtime to over-grant filesystem access beyond the files actually needed by the workflow.

## Operating rules

- **Ask the user which platform before every cloud run — including test and verification runs.**
  Never default to the currently active profile without asking (step 1.5), and never skip the
  platform + fee + count confirmation ceremony (step 8) for any run, test or not. The confirmation
  must come from the user after the numbers have been shown: silence, a previous run's approval, or
  an earlier platform choice is not a confirmation, and if the user does not respond you do not
Confidence
75% confidence
Finding
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
