osborn@0.9.237
Voice AI coding assistant - local agent that connects to Osborn frontend
AI Security Review
scanned 26d ago · by lpm-firewall-aiThe published package is a user-started voice coding agent with no npm install lifecycle and no self-install chain. Local Claude path usage, including the commented skill reader, is package-aligned and does not show a concrete exfiltration or hijack path.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
User invocation of the osborn or osborn-recall binaries.
Impact
No unconsented credential theft, remote payload execution, or agent control-surface mutation was established from the inspected entrypoints.
Mechanism
The running agent reads the local Claude session, skill, and credential files, and on Fly may link an existing /workspace/.claude directory into the home directory.
AI rationale
The published package is a user-started voice coding agent with no npm install lifecycle and no self-install chain. Local Claude path usage, including the commented skill reader, is package-aligned and does not show a concrete exfiltration or hijack path.
Decision evidence
public snapshotAI called this Clean at 86.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json has no preinstall, install, or postinstall script. Scripts are dev, start, build, and prepublishOnly, and the bins osborn and osborn-recall run only when the user launches them.
- Claude home paths are used after the agent starts to read local credentials, skills, projects, and session files. The flagged skill loader in dist/claude-llm.js is a commented-out dead function and is not wired into execution.
- bin/recall.js creates a home .claude symlink only when the user runs the CLI and /workspace/.claude already exists and the home path is not /workspace.
Evidence against
- Dependencies do not include a runtime self-dependency on osborn, and no install-time network, eval, or foreign agent-config writer was found.
- The OpenRouter fallback assigns the caller OPENROUTER_API_KEY to Anthropic env vars aimed at openrouter.ai only when Claude and Anthropic credentials are absent.
