Common build scripts and files

AI Security Review

scanned 4d ago · by lpm-firewall-ai

The package automatically updates project-level AI agent instructions when its configured build command runs, creating a residual configuration risk. The source ties the download to the package’s product domain and does not establish a concrete attack, so a warning is appropriate.

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

A user runs the build command configured by postinstall.

Impact

Project instructions consumed by AI tools may change, and existing files in the AGENTS directory may be removed.

Mechanism

The build updater fetches the archive and replaces AGENTS.md and the AGENTS directory without a consent prompt in that path.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest runs project cleanup before installation and asset synchronization after installation.
Postinstall copies package assets into the consumer project and changes its build script to run the packaged build code.
The build code targets project-root AGENTS.md and AGENTS files, and the build path calls its agent-instructions updater.
The updater fetches a versioned archive from htmlcodeplay.com and replaces the project’s AGENTS.md and AGENTS contents without a consent prompt in that path.

Evidence against

The agent-instructions update runs when the configured build command is invoked, rather than directly in an npm lifecycle hook.
The archive is fetched from the package’s product domain; the inspected behavior does not establish credential theft or an unrelated recipient.
