@companion-ai/feynman@0.3.12
Research-first CLI agent built on Pi and alphaXiv
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package is not malicious by source evidence, but its automatic CLI-time setup and patching of a packaged AI-agent runtime warrants a warning under the lifecycle-risk policy.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
User runs the feynman CLI.
Impact
Modifies Feynman-owned runtime files and linked bundled packages; may invoke a package manager when recovery is needed.
Mechanism
First-party Pi runtime setup, dependency restoration, and extension patching.
AI rationale
The package is not malicious by source evidence, but its automatic CLI-time setup and patching of a packaged AI-agent runtime warrants a warning under the lifecycle-risk policy.
Evidence
package.jsonbin/feynman.jsscripts/check-node-version.mjsscripts/patch-embedded-pi.mjs.feynman/settings.json.feynman/runtime-workspace.tgz.feynman/runtime-workspace.sha256~/.feynman/npm-global~/.feynman/agent/npm
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- bin/feynman.js imports patch-embedded-pi before launching dist.
- Patch script restores and patches a bundled Pi runtime on CLI use.
- It writes under ~/.feynman and patches pi-subagents/pi-otel there.
Evidence against
- preinstall only validates the Node version; it has no file or network mutation.
- The bundled .tgz is a SHA-256-checked runtime dependency workspace.
- Research API calls and environment keys are tool-specific, user-invoked functionality; no harvesting path found.
- No covert exfiltration, remote payload execution, or foreign agent-config write was found.
