AI-native notebook computing environment — real Jupyter kernels, real filesystem, built to be driven by agents (Claude Code / Codex) via MCP
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe only automatic lifecycle hook is disabled when installed as a dependency. The inspected launcher is user-invoked and starts the bundled server rather than fetching or executing a hidden payload.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installing the package or explicitly invoking the nebula-notebook command.
Impact
No unconsented mutation, credential export, or package-controlled attack behavior was established.
Mechanism
The install hook exits for node_modules installations, while the command launcher starts the bundled local server with caller-provided arguments.
AI rationale
The only automatic lifecycle hook is disabled when installed as a dependency. The inspected launcher is user-invoked and starts the bundled server rather than fetching or executing a hidden payload.
Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest registers a command launcher and a post-install script.
- The post-install script exits when it is running from node_modules, so it does not perform its checkout setup during a registry dependency installation.
- The launcher starts the package's bundled server only when the user invokes the command and forwards that user's arguments.
- The inspected browser bundle obtains its widget CDN setting from a page script attribute.
