claude-multiacc@2.0.54
Unified Claude Code and OpenAI Codex subscription pooling with quota-aware selection.
AI Security Review
scanned 15d ago · by lpm-firewall-aiThe automatic global-install setup creates persistent shell routing and scheduled execution, leaving a concrete install-time risk. Its behavior appears tied to the package’s own account-pooling tools, so the evidence supports a warning rather than a block.
Static reason
One or more suspicious static signals were detected.
Trigger
Global npm installation when CI and the skip conditions do not apply.
Impact
The package gains persistent command routing and recurring execution under the user account; no concrete credential theft or unrelated control-surface mutation was identified.
Mechanism
The postinstall hook runs install.sh, which updates PATH blocks and creates launchd or cron jobs for account limits, health checks, and self-updates.
AI rationale
The automatic global-install setup creates persistent shell routing and scheduled execution, leaving a concrete install-time risk. Its behavior appears tied to the package’s own account-pooling tools, so the evidence supports a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json defines a postinstall hook that runs the setup script.
- The hook runs automatically for global installs unless CI or a skip flag is set.
- Setup invokes the package installer, which adds PATH blocks to shell startup files.
- The installer creates recurring limit checks, health checks, and daily self-update jobs.
Evidence against
- The hook skips local installs, CI, Windows, and installs with the explicit skip flag.
- The installed shim and scheduled jobs operate the package’s account-pooling tools; no unrelated network destination or data theft was established.
