Common build scripts and files

AI Security Review

scanned 4d ago · by lpm-firewall-ai

The source confirms automatic agent-instruction replacement during a user-run build, with no separate confirmation for updates. The package-aligned source and build-time trigger do not establish malicious behavior, so this warrants a warning rather than a block.

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

The consumer runs the build command configured by the package’s postinstall sync script.

Impact

Updated instructions may affect later AI-agent behavior in the consumer project.

Mechanism

The build fetches a versioned archive from htmlcodeplay.com and replaces AGENTS.md and the AGENTS directory without asking for separate confirmation.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The manifest runs cleanup and file synchronization during npm installation.
The sync script places this package’s build script in the consumer’s build command.
That build calls agent-instructions synchronization without a separate confirmation.
When the remote version is newer, the script downloads an archive from htmlcodeplay.com and replaces project-root AGENTS.md and AGENTS/ contents.
The archive path checks reject absolute paths and entries containing `..`.

Evidence against

The agent-instructions update runs as part of a build command, not directly from the npm lifecycle hooks.
The archive is fetched from the package-aligned htmlcodeplay.com host and its entries receive path-traversal checks.
