instabox@0.8.41
A cloud box for your coding agent, the instabox CLI and its agent skills in one command: npx instabox@latest
AI Security Review
scanned 7d ago · by lpm-firewall-aiThe package has no npm install hook, and its agent-file writes are limited to its own skills during explicit CLI onboarding, preserving unmarked user skills. Credentials are sent with requests to the configured Instabox API; the remaining external traffic is usage telemetry with an opt-out.
Static reason
No blocking static signals were detected.
Trigger
The user invokes the CLI, typically through the documented npx onboarding command or a CLI command.
Impact
Expected CLI and onboarding behavior; no unauthorized credential transfer, destructive action, or broader agent configuration change was identified.
Mechanism
Onboarding authenticates to the configured Instabox API, may install the bundled CLI, copies package skills into the documented user skill directories, and sends limited usage telemetry unless disabled.
AI rationale
The package has no npm install hook, and its agent-file writes are limited to its own skills during explicit CLI onboarding, preserving unmarked user skills. Credentials are sent with requests to the configured Instabox API; the remaining external traffic is usage telemetry with an opt-out.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest defines a CLI entry point and has no preinstall, install or postinstall hook.
- Onboarding can skip skill installation with --no-skills; it installs this package’s skills into the documented agent skill directories.
- When a destination skill exists without the Instabox marker, the installer keeps it and skips that skill.
- API requests attach the session token as a Bearer token and send to the configured Instabox API base URL.
- Telemetry is sent as a separate POST and can be disabled with DO_NOT_TRACK or INSTABOX_NO_TELEMETRY.
- The bundled CLI update check fetches the vendor’s SHA256SUMS file to validate release binaries.
Evidence against
- Running the documented onboarding command installs or updates Instabox skills under the user’s Claude and agents directories by default.
- The package includes platform-specific native CLI binaries whose implementation is not fully readable in this review.
- Onboarding sends usage telemetry to the configured analytics host unless telemetry is disabled.
