Chemical X Protocol: Private drop-in architecture starter kit and capsule generator
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package has no install lifecycle hook, but its user-invoked scaffold flow retrieves unauthenticated remote content and writes unchecked paths. That is a concrete supply-chain risk, not enough source evidence of automatic malicious execution.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The user runs create, init, or another scaffold path and supplies a license key.
Impact
A compromised or malicious endpoint can place arbitrary content outside the requested project directory and influence an AI-enabled editor.
Mechanism
Remote file delivery with unchecked path writes and AI-agent rule creation.
AI rationale
The package has no install lifecycle hook, but its user-invoked scaffold flow retrieves unauthenticated remote content and writes unchecked paths. That is a concrete supply-chain risk, not enough source evidence of automatic malicious execution.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The explicit scaffold command downloads a server-supplied file map and writes every supplied path without validation or an integrity check.
- A remote response can use traversal segments to write outside the requested scaffold directory.
- Scaffolding also creates a Cursor rules file that instructs an AI agent to follow package-provided directives.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- The download and project writes occur only after a user invokes create or init and provides a license key.
- GitHub-token network use is confined to the explicit audit sharing path.
