OpenYida CLI - 宜搭低代码 AI 开发工具（安装即用，零配置）

AI Security Review

scanned 17d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall mutates multiple third-party AI-agent skill/control directories without a user command. It installs package-supplied skills and enables a local Codex plugin/MCP entry.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

npm install, including global installation

Impact

Persistent foreign agent-control-surface modification; subsequent agent sessions can load package instructions and invoke its CLI.

Mechanism

unconsented install-time AI-agent skill and plugin injection

Policy narrative

Installation automatically copies OpenYida skills into Claude Code even when it was not previously configured, and into several detected AI-agent directories. When Codex exists, it creates a local marketplace/plugin containing an MCP command and edits config.toml to enable it. These mutations occur in postinstall, without an explicit setup command or consent.

Rationale

This is concrete unconsented postinstall mutation of broad, foreign AI-agent control surfaces. The absence of network exfiltration does not remove the install-time control-surface abuse.
