Installing the package triggers remote code download and execution for Claude by default. It also downloads unpinned skills and installs additional global tooling during postinstall.

Static reason

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

Trigger

npm postinstall

Impact

Arbitrary code supplied by the remote installer or mutable skills repository can run or be activated without an explicit install-time opt-in.

Mechanism

remote installer execution and unpinned skill staging

Attack narrative

A normal dependency installation runs the package postinstall. Unless an opt-out variable is set, it fetches a Claude installer to a temporary file and invokes it, while also fetching a mutable skills repository and auto-activating selected content. This creates an unconsented install-time remote-code supply chain rather than limiting setup to packaged, first-party files.

Rationale

The package has a concrete, default postinstall remote-payload execution chain and stages unpinned externally fetched skills for activation. Opt-in protection for shared-path migration does not mitigate those default lifecycle actions.
