AI Security Review

scanned 15d ago · by lpm-firewall-ai

The install hook automatically runs package-owned setup on global installs, creating an agent extension lifecycle risk that merits a warning. Inspected evidence does not establish malicious behavior or justify blocking publication.

Static reason

One or more suspicious static signals were detected.

Trigger

Installing globally with npm, unless the configured skip or CI condition applies.

Impact

The package can change command lookup and schedule its own jobs for account management.

Mechanism

The postinstall launches install.sh, which configures this package's own integration.

AI rationale

Evidence

package.jsonscripts/postinstall.mjslib/install_actions.shinstall.sh

Decision evidence

public snapshot

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

Evidence for warning

package.json registers a postinstall lifecycle script.
The postinstall skips local installs, but on global installs it runs the package's installer.
The installer sets up this package's own PATH shim and scheduled jobs.
The test finding is a test module describing sandboxed fixtures, not an executable payload.

Evidence against

The install action is gated to global installs and supports skipping the postinstall.
Inspected code shows first-party setup; no unrelated recipient or concrete malicious behavior was established.

2// Runs after `npm install`. On a GLOBAL install/update it wires the addon up by

3// running install.sh (idempotent), so `npm i -g claude-multiacc@latest` fully updates

4// the shim, CLI, and scheduled jobs with no extra step. Deliberately best-effort:

5// npm's own CI, sandboxes, and non-global/dev installs must never be broken by it, and

6// a failed install.sh must not fail `npm install` — it only prints how to finish by hand.
