tina4-nodejs@3.13.132
Tina4 for Node.js/TypeScript - native TypeScript conventions and shared Tina4 contracts
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe source establishes a real, explicit-user-command agent configuration risk, so a warning is appropriate. Source inspection found no automatic install hook, credential redirection, or concrete exfiltration behavior supporting a malicious verdict.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
The user runs tina4nodejs ai and selects Claude, or runs it with --all.
Impact
Remote content can influence Claude Code behavior in the current project and other projects for that user.
Mechanism
Remote skill download followed by project and global assistant-skill writes.
AI rationale
The source establishes a real, explicit-user-command agent configuration risk, so a warning is appropriate. Source inspection found no automatic install hook, credential redirection, or concrete exfiltration behavior supporting a malicious verdict.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The explicit AI CLI command installs assistant context files.
- Selecting Claude writes skills to both the project and the user's global Claude directory.
- The installer fetches remote files and writes their bytes to those destinations.
Evidence against
- No preinstall, install, or postinstall hook is declared; prepare only runs the package build.
- AI API keys are sent only to the configured provider endpoint, with official OpenAI and Anthropic defaults.
