PomoClaw

Security checks for vulnerabilities and agentic risk

Overview

The skill is a coherent PomoClaw timer controller, but it should be reviewed because it tells the agent to pass timer URLs through a shell command on a Mac.

Install only if you are comfortable with the agent running Mac-node commands to control PomoClaw. Timer durations and configuration values should be strictly limited to the documented numeric ranges and sound names, and malformed text should be rejected rather than placed into the shell command.

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

Session Persistence

Medium

Category: Rogue Agent
Confidence: 60% confidence
Finding: Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
