instabox@0.8.159
A cloud box for your coding agent, the instabox CLI and its agent skills in one command: npx instabox@latest
AI Security Review
scanned 5h ago · by lpm-firewall-aiThe package has no install hook, and the inspected JavaScript routes user-invoked CLI actions while limiting onboarding telemetry to disclosed usage fields with an opt-out. The changed platform binaries were not behaviorally decoded, but their packaging and dispatch match the package’s stated CLI purpose and do not independently indicate malicious behavior.
Static reason
No blocking static signals were detected.
Trigger
The user invokes the CLI; skill copying occurs through onboarding or `skills install`, and dependency downloads occur when the move-repo setup script is run on the box.
Impact
No malicious impact identified. Normal side effects include usage telemetry, installation of the package’s skills, and runtime setup on the remote box.
Mechanism
Onboarding reports command outcome and runtime/platform fields to PostHog under the account’s instabox user ID. The setup helper conditionally downloads runtime installers; no install lifecycle hook triggers these actions.

Decision evidence
public snapshotAI called this Clean at 90.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json declares no install, preinstall, or postinstall hook; its only lifecycle-like script is prepack.
- Telemetry is disclosed as command names and outcomes, never arguments, with INSTABOX_NO_TELEMETRY and DO_NOT_TRACK opt-outs.
- Onboarding telemetry uses the instabox account user ID and sends the documented usage fields to PostHog only when the configured server is api.instabox.sh.
- Skill installation is an explicit CLI command that copies this package’s skills into agent skill directories; the dependency setup downloads runtimes only when needed.
Evidence against
- The package ships six platform-specific CLI binaries; two Windows binaries changed in this version, and the available binary inspection was limited.
- The move-repo dependency helper downloads and runs installers from mise.run, raw.githubusercontent.com, bun.sh, and astral.sh when the user runs that helper on the box.
