tina4-nodejs@3.13.142
Tina4 for Node.js/TypeScript - native TypeScript conventions and shared Tina4 contracts
AI Security Review
scanned 1mo ago · by lpm-firewall-aiSource supports an explicit user-command agent configuration capability, which the supplied policy assigns a warning. The inspected behavior does not establish malicious intent or an unconsented npm install attack.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Run tina4nodejs ai and select tools, or supply --all; alternatively call the exported setup methods.
Impact
Downloaded instructions can influence agents across projects through global Claude skills. Consent activates the requested setup; no recurring automatic update mechanism was established.
Mechanism
Setup merges context files and fetches skills from Tina4 repositories into project and home directories. A callable MCP method writes a localhost configuration entry.
AI rationale
Source supports an explicit user-command agent configuration capability, which the supplied policy assigns a warning. The inspected behavior does not establish malicious intent or an unconsented npm install attack.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The explicit AI setup command requires a menu selection or --all.
- Skill setup downloads package-aligned GitHub content and writes it into project and global Claude skill directories.
- Selected AI tools receive context file updates; selecting Claude also installs skills.
- The callable MCP configuration method writes a localhost server entry into Claude settings.
- package.json has no preinstall, install, or postinstall hook; prepare runs the build.
Evidence against
- No concrete malicious execution or credential exfiltration was established.
- The flagged bundle locations list documentation files rather than modifying agent configuration.

Critical
Credential Exfiltration
Source appears to send environment or credential material to an external endpoint.
