@companion-ai/feynman@0.3.42
Research-first CLI agent built on Pi and alphaXiv
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe scanner's archive, dynamic-import, and network indicators map to an embedded runtime and research features, not a concrete malicious chain. Runtime patching merits a warning, but the inspected preinstall hook is non-malicious.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
User runs the feynman CLI.
Impact
Changes the package-owned Feynman runtime; no confirmed exfiltration or foreign agent-control-surface mutation.
Mechanism
Runtime setup and patching of embedded Pi dependencies.
AI rationale
The scanner's archive, dynamic-import, and network indicators map to an embedded runtime and research features, not a concrete malicious chain. Runtime patching merits a warning, but the inspected preinstall hook is non-malicious.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Preinstall runs only the local Node-version checker.
- The user-invoked launcher imports a runtime patcher before the app.
- That patcher transactionally installs and patches an embedded Pi runtime.
Evidence against
- Version checker only prints compatibility guidance and exits for unsupported Node.
- No preinstall/install code performs network access, credential harvesting, or agent-config mutation.
- Hugging Face token use is limited to Authorization headers for its named API.
