Enterprise AI Git Collaboration Governance & Smart Skill Hub for Heterogeneous AI Agents
AI Security Review
scanned 6d ago · by lpm-firewall-aiSource confirms an automatic postinstall trigger and writes to multiple AI agent configuration files without a consent gate. This meets the policy for blocking unconsented lifecycle mutation of a broad AI agent control surface.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installing the package into an external project triggers its postinstall hook.
Impact
The package changes instructions that AI coding tools may follow in the consumer project, creating an unconsented agent control surface.
Mechanism
The hook calls setupGovernance, which writes AGENTS.md and agent-specific configuration files, including Claude, Cursor, Gemini, and Copilot instruction locations.
Policy narrative
The package manifest activates a postinstall script that calls setupGovernance for an external project without an affirmative consent check. That function writes package-generated instructions into AGENTS.md and multiple AI agent configuration locations; the generated text directs AI tools to follow the new constitution. This is unconsented lifecycle mutation of a broad AI agent control surface.
AI rationale
Source confirms an automatic postinstall trigger and writes to multiple AI agent configuration files without a consent gate. This meets the policy for blocking unconsented lifecycle mutation of a broad AI agent control surface.
Evidence
package.jsonbin/postinstall.jsbin/harness-bridge.js
Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 98.0% confidence with low false-positive risk.
Evidence for policy risk
- The bridge is designed to connect several AI coding tools to AGENTS.md and synchronize skills.
- The package manifest runs bin/postinstall.js automatically after installation.
- For an external project, the postinstall hook calls setupGovernance without requesting consent.
- setupGovernance writes generated governance instructions to AGENTS.md and multiple agent-specific configuration files.
- The generated instructions tell AI coding tools they must follow the package-generated constitution.
- The hook’s external-project check excludes the package’s own directory, but does not require user approval.
