AI Security Review

scanned 11d ago · by lpm-firewall-ai

The source supports a warning for user-triggered agent configuration setup: a workflow links the package's deploy skill into a workspace's Claude skills directory. Credential pairing uses the selected server and a browser approval token, and the package has no npm install lifecycle hook in its manifest.

Static reason

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

Trigger

A user invokes the deploy-skill approval workflow for a space.

Impact

Claude may discover and use the deploy skill in that workspace; the reviewed code does not establish a covert or install-time change.

Mechanism

The workflow checks the workspace contract and creates .claude/skills/deploy as a symlink to .agents/skills/deploy when no link already exists.

AI rationale

Evidence

dist/cli.js

Decision evidence

public snapshot

AI called this Suspicious at 85.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The CLI can create a workspace-local Claude skill link to the package's deploy skill.
The link is created by an approval workflow after reading the workspace contract.
The pairing flow sends a runner name to the selected server and asks the user to paste an approval token.
The manifest has a prepublishOnly build hook, not an install hook.

Evidence against

The agent configuration change is limited to an explicit deploy-skill approval workflow and workspace-local symlink.
Pairing stores a token returned through the browser approval flow; the server is configurable by the user.
The vendor save script inspected formats tmux session and pane state for saving.
