Security audit

officecli-docx

Security checks across malware telemetry and agentic risk

Overview

This Word-document skill is mostly coherent, but its broad activation wording and pipe-to-shell installer create enough install-time risk that users should review it before use.

Install only if you intentionally need officecli for .docx work. Review or replace the remote installer with a pinned release or verified package, and do not let an agent run the setup command automatically just because a generic document, report, letter, or memo was mentioned.

Vague Triggers

High
Confidence
95% confidence
Finding
The trigger text is extremely broad, matching generic terms like 'document', 'report', 'letter', and 'memo'. That can cause this skill to activate for many unrelated tasks, increasing the chance an agent follows its embedded setup and execution guidance in contexts where the user did not explicitly request this toolchain.

Missing User Warnings

Medium
Confidence
98% confidence
Finding
The skill instructs the agent to install software by piping a remote network response directly into a shell or PowerShell interpreter, with no integrity verification, pinning, or warning. If the download host, network path, or served script is compromised, this becomes immediate arbitrary code execution on the host running the agent.

If `officecli` is missing:

- **macOS / Linux**: `curl -fsSL https://d.officecli.ai/install.sh | bash`
- **Windows (PowerShell)**: `irm https://d.officecli.ai/install.ps1 | iex`

Verify with `officecli --version` (open a new terminal if PATH hasn't picked up). If install fails, download a binary from https://github.com/iOfficeAI/OfficeCLI/releases.
