@companion-ai/feynman@0.3.13
Research-first CLI agent built on Pi and alphaXiv
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe malicious scanner verdict is unsupported by the inspected preinstall source, which only validates Node.js. Runtime self-patching of an embedded agent stack remains a real, package-aligned lifecycle risk and merits a warning rather than a block.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
User runs the feynman CLI.
Impact
A compromised package release could control its persisted agent runtime; current source does not establish malicious payload behavior.
Mechanism
first-party Pi runtime extraction, linking, and source patching
AI rationale
The malicious scanner verdict is unsupported by the inspected preinstall source, which only validates Node.js. Runtime self-patching of an embedded agent stack remains a real, package-aligned lifecycle risk and merits a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 85.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- bin/feynman.js imports patch-embedded-pi before CLI runtime.
- patch-embedded-pi.mjs extracts and patches bundled Pi dependencies.
- Runtime patch sets npm prefix under $FEYNMAN_HOME and links packages.
- Packaged .feynman/runtime-workspace.tgz is an executable dependency archive.
Evidence against
- preinstall only checks supported Node version; no writes or network.
- Archive is SHA-256 verified before extraction.
- Reviewed source shows no credential harvesting or unconsented exfiltration.
- OAuth token exchange is an explicit workbench connector flow.
