Security audit

Flowchart

Security checks for vulnerabilities and agentic risk

Overview

This skill is a coherent CellCog diagram-generation guide, with expected external-service and install risks users should understand before use.

Install only from a CellCog source you trust, prefer pinned versions where possible, and do not include secrets, credentials, regulated data, or internal-only architecture details unless you intend to send them to CellCog and potentially create a shareable hosted output.

Vulnerability Patterns
  • Insecure DependenciesIntroduces malicious components through unsafe dependency sources
  • 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

Finding

The skill repeatedly encourages users to describe their systems and processes, and explicitly states CellCog will deploy an interactive web application shareable via URL, but it does not clearly warn that potentially sensitive architectural, organizational, or database information is sent to an external service. This omission can lead users to disclose confidential data or internal diagrams unintentionally, increasing privacy and data-exposure risk.

Finding

The skill instructs users to run npx skills add cellcog/skills --skill cellcog without pinning a specific package version. That creates a supply-chain risk because users may fetch whatever version is current at install time, including a compromised or malicious update. In this context, the risk is real but limited to setup/install time rather than direct runtime exploitation from this file alone.
