AI Security Review

scanned 12d ago · by lpm-firewall-ai

The flagged install-time and process-launch behavior serves tfcode's platform binary and Python integration setup. The inspected source shows no concrete malicious behavior or unrelated target mutation.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

npm runs the declared postinstall hook during installation; Python setup runs when python3 is available.

Impact

These actions set up tfcode and its integration; inspected source does not establish credential theft, unrelated control-surface changes, or another attack.

Mechanism

The hook detects the platform, links or copies the corresponding binary into this package, and installs the named Python SDK dependencies for the integration.

AI rationale

Evidence

postinstall.mjsbin/tfcode.js

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json runs a postinstall setup script and declares platform-specific optional packages for tfcode.
postinstall.mjs resolves the matching platform package and links or copies its binary into this package's bin directory.
When Python is available, postinstall.mjs installs the ToothFairyAI Python SDK and its listed dependencies for TF integration.
bin/tfcode.js resolves the matching ToothFairyAI platform package and launches its binary with the caller's arguments.
