sdd-flow-kit@1.8.1

Cross-agent SDD automated development workflow kit with PRD layered architecture, task splitting, context compression, and pending confirmations.

AI Security Review

scanned 27d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package automatically changes the consuming project's AI-agent configuration and permissions. It writes workflow material into several agent control directories and broadens Claude Code command approval rules.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

npm installation runs postinstall.

Impact

A dependency installation can alter how multiple AI coding agents operate in the consumer project and reduce command-confirmation protections.

Mechanism

Unprompted cross-agent control-surface and permission mutation.

Policy narrative

On installation, the lifecycle hook identifies the consuming project, selects an agent, and invokes setup with confirmation bypassed. Setup writes skills and trigger rules into four different AI-agent directories, changes Cursor rules, and merges a broad Claude Code command allowlist. These are foreign project control surfaces changed automatically by a dependency install.

AI rationale

This is an unconsented postinstall mutation of broad AI-agent control surfaces in the consumer project. The lack of network theft does not remove the concrete install-time control-hijack risk.
