AI Security Review
scanned 28d ago · by lpm-firewall-aiSource inspection did not confirm the scanner’s credential-redirection claim: the agent-path findings are skills bootstrap locations, and the install hook runs package Python setup with skip controls. The inspected facts support a clean verdict.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Package installation triggers the postinstall Python setup; the inspected agent skills helper is delivered for later use.
Impact
No malicious impact was confirmed from the inspected source.
Mechanism
The manifest and inspected source show package-local setup and a skills-directory manifest, without evidence that installation silently forwards credentials or changes agent configuration.
AI rationale
Source inspection did not confirm the scanner’s credential-redirection claim: the agent-path findings are skills bootstrap locations, and the install hook runs package Python setup with skip controls. The inspected facts support a clean verdict.
Decision evidence
public snapshotAI called this Clean at 87.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest’s install hooks run a Node-version check and Python setup; no self-dependency chain is present in the inspected manifest.
- The postinstall setup has explicit environment-variable skip controls.
- The flagged agent paths belong to a client skills-directory manifest; the inspected code does not establish automatic writes to those directories during npm installation.
- The CLI dispatches only named Python and Whisper setup commands.
- The Python setup command targets the package’s own `ee/python/setup.sh`.
- The flagged Python test file defines a stub pipeline; the chunk entry imports ordinary application dependencies.
