instabox@0.8.121
A cloud box for your coding agent, the instabox CLI and its agent skills in one command: npx instabox@latest
AI Security Review
scanned 3d ago · by lpm-firewall-aiThe package has no npm install lifecycle hook, and its reviewed automatic behavior occurs when a user invokes the CLI for onboarding. Its disclosed, opt-out-capable telemetry sends usage outcomes and ordinary runtime details to PostHog using the Instabox account ID; no credential theft or unrelated account action was identified.
Static reason
No blocking static signals were detected.
Trigger
User invokes the CLI; onboarding and repository-move setup run only as part of their requested commands.
Impact
No malicious impact identified in the reviewed source.
Mechanism
The CLI communicates with the Instabox API, sends disclosed and opt-out-capable usage telemetry to PostHog, and installs the package’s own CLI and agent skills. The move-repo helper can install missing project runtimes when run.
AI rationale
The package has no npm install lifecycle hook, and its reviewed automatic behavior occurs when a user invokes the CLI for onboarding. Its disclosed, opt-out-capable telemetry sends usage outcomes and ordinary runtime details to PostHog using the Instabox account ID; no credential theft or unrelated account action was identified.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json declares no preinstall, install, or postinstall hook.
- The CLI discloses usage telemetry and documents opt-out variables; events contain command outcomes and ordinary runtime details, not names or arguments.
- Telemetry uses the account ID returned by Instabox and is sent only when the API server is the default Instabox server and telemetry is enabled.
- The package’s skills are copied into agent skill folders by the explicitly invoked CLI; existing skills not marked as installed by Instabox are preserved.
- The repository-move skill describes transferring project files and agent conversation history as a user-requested workflow.
Evidence against
- The CLI uses network access, stores sign-in credentials, and installs its bundled CLI and skills when onboarding is invoked.
- The move-repo helper can download runtimes and add PATH setup to shell profile files when its documented workflow is run.
- Native CLI binaries were not independently inspected; the JavaScript wrapper installs and invokes the package’s bundled CLI.
