Shared build configuration for TypeScript projects — ESLint, Prettier, tsconfig, and Playwright presets

AI Security Review

scanned 18d ago · by lpm-firewall-ai

Inspected behavior is consistent with TypeScript build tooling, and the scanner's similarity and entropy labels do not establish an attack. The lifecycle self-dependency rule does not apply because the self-reference is development-only and the installer is transparent.

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 installation activates configuration seeding; users invoke the additional CLI operations.

Impact

Expected project setup changes occur; no credential theft, remote payload execution, or AI-agent control mutation was established.

Mechanism

The inspected code copies package templates, preserves existing files, and uses ordinary tooling commands for configuration and browser setup.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 94.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest activates a transparent build-configuration postinstall hook; its self-dependency is development-only.
The install hook preserves existing configuration and seeds missing pipeline files; differences receive a local diff.
The Playwright helper locates Chromium using fixed command names and returns its executable path.
The PDF contains compressed PDF objects; inspected executable paths do not load or execute it.
