osborn@0.9.172

Voice AI coding assistant - local agent that connects to Osborn frontend

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

The package has risky runtime behavior and broad agent integration, warranting a warning. Static inspection found no automatic registry-install execution or concrete credential exfiltration.

Static reason

High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source

Trigger

A user runs the osborn CLI or starts its IDE feature.

Impact

A user-enabled agent can alter local agent settings and execute code supplied by the installer host.

Mechanism

Claude configuration mutation and remote shell installer execution.

AI rationale

The package has risky runtime behavior and broad agent integration, warranting a warning. Static inspection found no automatic registry-install execution or concrete credential exfiltration.

Decision evidence

public snapshot

AI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

On CLI runtime import, it changes the user's Claude settings file and environment variables.
Its IDE feature downloads and executes a remote shell installer when code-server is absent.
The package exposes an agent wrapper that can operate in the configured working directory.

Evidence against

There is no npm install, preinstall, or postinstall hook; prepublishOnly only builds before publishing.
The observed API requests use configured service keys for the voice and meeting features, not harvested environment data.
The remote installer is reached from an IDE-start feature, not automatically during installation.
