Creative Writing

Security checks for vulnerabilities and agentic risk

Overview

The skill sends writing tasks to CellCog as advertised, with ordinary privacy and dependency-installation considerations.

Prompts and any manuscript text you include are sent to CellCog, so share confidential work only if you intend that disclosure. Review the separate CellCog dependency and use reviewed versions where possible. Check its background-notification controls for OpenClaw. This assessment covers the supplied instructions, not the external SDK or service.

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
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code
  • 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
Findings (2)

The usage workflow sends user writing prompts to CellCog without a privacy warning.

Finding

The skill instructs the agent to submit the user's task prompt through CellCog's create_chat API. Although CellCog is named as the provider, the file does not explicitly warn that prompts and included unpublished writing or personal details are transmitted to a third-party service.

MCP server referenced without pinned version: 'npx skills'.

Confidence
88% confidence
Finding

The setup command invokes an unpinned npm executable through npx skills, potentially downloading and running a changing package version with the agent user's privileges. A compromised upstream release could therefore execute malicious code during installation; this is a supply-chain exposure, although the static finding incorrectly describes the command as an MCP server reference.
