@lystech/core@3.0.113
Lystech Core contains essentials for lystech apps
AI Security Review
scanned 13d ago · by lpm-firewall-aiThe automatic postinstall workflow creation and registry reporting present a real install-time side effect, so warn. The inspected source supports package-aligned setup behavior but does not establish a concrete malicious attack.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Installing the package in a project that lists @lystech/core as a dependency, unless the workflow already exists or SKIP_LYSTECH_SETUP is true.
Impact
An installation can add ongoing repository automation and transmit repository identifiers to the package publisher's registry. The inspected source does not establish credential theft or unrelated data exfiltration.
Mechanism
The hook writes a workflow file that runs on pushes and workflow dispatch, checks for the package dependency, and registers or removes repository metadata through the Lystech registry API.
AI rationale
The automatic postinstall workflow creation and registry reporting present a real install-time side effect, so warn. The inspected source supports package-aligned setup behavior but does not establish a concrete malicious attack.

Decision evidence
public snapshotAI called this Suspicious at 81.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs a postinstall script that can create a GitHub Actions workflow in the consuming project when that project lists @lystech/core as a dependency.
- The workflow registers repository metadata with a Lystech package registry; the file write occurs automatically during postinstall when the workflow is absent.
Evidence against
- The workflow checks whether @lystech/core is a dependency, and the script supports a SKIP_LYSTECH_SETUP opt-out.
- The bundle's API endpoint is api.lystech.ca and is used for organization requests; inspected excerpts did not establish unrelated credential forwarding.
