Security audit

Call

Security checks for vulnerabilities and agentic risk

Overview

This skill is a local call-notes helper that discloses sensitive local storage, but users should be deliberate about when it captures conversation details.

Install only if you want a local memory system for calls and follow-ups. Because call notes can include sensitive business or personal details, use it intentionally, avoid capturing conversations casually, and periodically review or delete records under the local memory/calls storage.

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

Undeclared Tool Scope

Medium

MCP Least Privilege
Confidence

Finding

The skill advertises local file-backed storage and references reading from prior call history, but it does not declare any explicit tool scope such as permissions or allowed-tools. That mismatch can lead to overbroad implicit file access at runtime and makes it harder to enforce least privilege for sensitive call records.

Vague Triggers

Confidence

Finding

The invocation description is very broad, covering ordinary mentions of phone calls, meetings, conversations, commitments, or follow-ups. This can cause the skill to activate on routine user dialogue and unnecessarily collect, store, or infer sensitive interpersonal and business information in local memory without sufficiently clear user intent.
