AI Security Review
scanned 13h ago · by lpm-firewall-aiThe source establishes package-owned agent-instruction updates that can replace project-level agent configuration during a build. Because the update is build-triggered and no malicious content is established, this warrants a warning rather than a publish 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 added by the package’s postinstall setup.
Impact
Downloaded instructions can affect how AI coding agents operate in the consumer project; no malicious instruction content or other attack was established from the inspected source.
Mechanism
The script checks for a newer instruction version, downloads an archive from htmlcodeplay.com, then replaces the project’s AGENTS directory and writes AGENTS.md.
AI rationale
The source establishes package-owned agent-instruction updates that can replace project-level agent configuration during a build. Because the update is build-triggered and no malicious content is established, this warrants a warning rather than a publish block.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs cleanup and project setup scripts automatically during installation.
- Its setup script installs a build command that runs the package’s build script.
- Both build-script versions target the consumer project’s AGENTS.md and AGENTS directory, and call the instruction sync during the build.
- The sync checks for a newer instruction version and downloads its archive from htmlcodeplay.com.
- When an update is available, the script replaces the AGENTS directory and writes the downloaded AGENTS.md and support files into the project root.
Evidence against
- The agent-file update runs when the consumer invokes the build command, rather than directly in the npm lifecycle hook.
- The update requires a newer remote version; the download host is associated with the package’s Codeplay product.
