@companion-ai/feynman@0.3.35
Research-first CLI agent built on Pi and alphaXiv
AI Security Review
scanned 2mo ago · by lpm-firewall-aiStatic inspection does not substantiate the scanner’s malicious label. The compressed runtime is an identified, hash-recorded dependency workspace, while the flagged AI-agent directory mutation is confined to an explicit installer command.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
npm install runs the version checker; running feynman starts its package-local runtime setup.
Impact
No unconsented credential harvesting, exfiltration, remote payload execution, or foreign AI-agent control-surface mutation was established.
Mechanism
local version validation and package-owned CLI runtime initialization
AI rationale
Static inspection does not substantiate the scanner’s malicious label. The compressed runtime is an identified, hash-recorded dependency workspace, while the flagged AI-agent directory mutation is confined to an explicit installer command.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
Evidence against
- The only npm lifecycle hook runs a local Node-version compatibility check.
- The preinstall source only reports unsupported versions and may exit; it has no network, file-write, or child-process action.
- The CLI imports package-local runtime setup and application entrypoints.
- The bundled runtime archive has a matching recorded SHA-256 and declares Pi-related runtime dependencies.
- The skills installer modifies AI-agent skill directories only when explicitly invoked with a chosen scope.
