Chemical X Protocol: Private drop-in architecture starter kit and capsule generator
AI Security Review
scanned 1mo ago · by lpm-firewall-aiNo automatic lifecycle execution or self-dependency chain exists. However, explicit use of the CLI downloads unauthenticated-by-integrity content and writes unchecked server-selected paths, creating a concrete supply-chain risk.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
User runs the create or init CLI flow and supplies a license key.
Impact
A compromised or malicious service response could overwrite files outside the selected project and add AI-agent instructions.
Mechanism
Remote payload download followed by unchecked filesystem writes.
AI rationale
No automatic lifecycle execution or self-dependency chain exists. However, explicit use of the CLI downloads unauthenticated-by-integrity content and writes unchecked server-selected paths, creating a concrete supply-chain risk.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The scaffold fetches a server-supplied file map and trusts it as the installation payload.
- Returned file paths are joined and written without path validation, allowing traversal outside the chosen target directory.
- The scaffold also creates a Cursor rules file containing agent directives.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- Scaffolding and in-repository installation require an explicit CLI command and a supplied license key.
- GitHub-token network use is reached through the explicit audit sharing flow.
