@companion-ai/feynman@0.3.23
Research-first CLI agent built on Pi and alphaXiv
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe flagged archive and dynamic imports support a packaged CLI runtime, while source confines operational patching to Feynman's own matched Pi dependency surfaces. No concrete malicious behavior was found by static inspection.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
npm install; explicit feynman CLI invocation
Impact
No confirmed unconsented exfiltration, remote payload execution, or foreign AI-agent control-surface mutation.
Mechanism
local version check and Feynman-scoped Pi runtime patching
AI rationale
The flagged archive and dynamic imports support a packaged CLI runtime, while source confines operational patching to Feynman's own matched Pi dependency surfaces. No concrete malicious behavior was found by static inspection.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with medium false-positive risk.
Evidence for AI clean decision
- CLI startup imports a runtime patcher before launching the application.
- The patcher can rewrite matching Pi runtime files under Feynman-controlled package roots.
Evidence against
- The sole preinstall hook only checks the running Node version and exits on unsupported old versions.
- Runtime patches are restricted to the bundled Pi version and app/.feynman dependency roots.
- The shipped archive is a SHA-256-verified packaged runtime workspace, not a source-hidden downloader.
- No install-time network, credential harvesting, exfiltration, or foreign agent-config write was found.
