Security audit

Tunnel Vision & Slack

Security checks for vulnerabilities and agentic risk

Overview

This time-management skill needs review because its instructions leave recurring calendar changes and automatic meeting declines insufficiently controlled.

The advisory calendar concern is supported by the workflow's direct-action wording, although no calendar integration or executable automation is bundled. Static scanning reported no findings, and the artifacts show no malicious intent. Use the skill for planning first; before applying changes, agree on the calendar, slots, end date, invitation exceptions, and how to disable automatic declines.

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
  • Output HandlingUnvalidated Output Injection, Cross-Context Output, Unbounded Output
  • 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
Findings (1)

The workflow directs recurring calendar blocking and automatic meeting declines without warning about their effects on existing scheduling and invitations.

Finding

These are steps in the skill's own workflow, not merely a catalog of available tools. Creating recurring blocks and enabling auto-decline can alter calendar availability and reject invitations, but the skill does not warn the user about those consequences or require approval before applying changes.
