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

AI Security Review

scanned 27d ago · by lpm-firewall-ai

Osborn is a user-invoked voice coding assistant whose Claude home reads and writes match that product and are not triggered by npm install hooks. Inspected entrypoints and agent paths show no covert exfiltration or foreign control-surface mutation.

Static reason

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

Trigger

User runs the osborn or osborn-recall binary; npm install does not execute package code.

Impact

No unconsented install mutation, secret theft, or remote payload execution was identified.

Mechanism

The running agent reads the local Claude credential and session directories and talks to the configured voice and model services.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 84.0% confidence as Benign with medium false-positive risk.

Evidence for AI clean decision

package.json has no preinstall, install, or postinstall hook; the only publish script is prepublishOnly running the build.
Claude home paths are used at runtime by the voice agent to check local Claude credentials, list project sessions, and read skill files after the user starts the CLI.
bin/recall.js only spawns the local recall CLI when the user runs the osborn-recall binary.
The agentDir .claude/skills loader in claude-llm.js is commented out and is not executed.

Evidence against

Session export and skill writes run only inside the started agent process, not during npm install.
Outbound calls go to the product's own services (OpenAI TTS, OpenRouter, Recall, LiveKit, the official code-server installer) when the user starts those features.
