AI Security Review

scanned 1mo ago · by lpm-firewall-ai

This is a real automatic agent-extension lifecycle risk, but the write scope is namespaced and the remote path is authenticated and configuration-gated. Static inspection found no secret harvesting, arbitrary shell execution during postinstall, or self-dependency chain.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Installing the package runs postinstall; remote synchronization additionally requires MCP URL and access-token environment variables.

Impact

Agent instructions in the consumer project can be added or replaced without an explicit skill-install command.

Mechanism

Automatic local and authenticated remote agent-skill installation.

AI rationale

Evidence

package.jsoncli/postinstall.mjscli/install-agent-skills.mjscli/install-mcp-skills.mjscli/mcp-platform-skills.mjsagent_scaffold/skills<consumer project>/.agents/skills/command-center<consumer project>/.agents/skills/mainsequence

Decision evidence

public snapshot

AI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package runs a postinstall hook that automatically installs agent skills into the consumer project.
The installer writes packaged content under the consumer project's .agents skills control surface.
When configured with an MCP URL and access token, postinstall fetches remote skill content and writes it under a second agent-skill namespace.

Evidence against

The remote synchronization requires both a configured URL and access token, and failures do not block installation.
The installers restrict paths, reject symlinks, and use package-specific namespaces.
