@companion-ai/feynman@0.3.44
Research-first CLI agent built on Pi and alphaXiv
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe high-risk scanner signals are explained by a packaged application runtime and explicit CLI setup behavior. Direct inspection found no concrete malicious chain or install-time mutation beyond a Node.js version check.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Installing the package runs the compatibility check; running feynman loads its bundled runtime patcher.
Impact
No confirmed credential theft, exfiltration, remote payload execution, destructive action, or foreign AI-agent control-surface mutation.
Mechanism
User-invoked patching of the package’s bundled Pi runtime.
AI rationale
The high-risk scanner signals are explained by a packaged application runtime and explicit CLI setup behavior. Direct inspection found no concrete malicious chain or install-time mutation beyond a Node.js version check.

Decision evidence
public snapshotAI called this Clean at 93.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- The package declares a preinstall lifecycle hook.
- The executable imports a local runtime patcher before loading the application.
- A large bundled runtime archive contains named, pinned dependencies.
Evidence against
- The preinstall hook only checks the running Node.js version and can exit for an unsupported version.
- The patcher runs from the user-invoked feynman command, not from preinstall.
- The inspected patch targets configure and patch Feynman’s bundled Pi runtime; no foreign agent configuration write, credential harvesting, or exfiltration was found.
- The bundled archive manifest identifies a private runtime with version-pinned dependencies, consistent with an application runtime bundle.
