tina4-nodejs@3.13.141
Tina4 for Node.js/TypeScript - native TypeScript conventions and shared Tina4 contracts
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package contains real AI-agent configuration capabilities that warrant a warning because they can affect global assistant behavior. Static inspection found no automatic lifecycle activation or concrete malicious payload behavior.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user runs the AI-context CLI command, selects an installer option, uses --all, or calls the MCP configuration method.
Impact
A user-approved action can extend an AI assistant's project or global instructions. No confirmed unconsented execution, credential exposure, or install-time mutation was established.
Mechanism
The installer fetches Tina4 skill files and writes them to project and global Claude directories; the MCP method writes a local Claude settings entry.
AI rationale
The package contains real AI-agent configuration capabilities that warrant a warning because they can affect global assistant behavior. Static inspection found no automatic lifecycle activation or concrete malicious payload behavior.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The CLI AI-context command requires either a user menu selection or the explicit --all flag.
- The AI installer downloads skills into both the selected project and the user's global Claude skills directory.
- A public MCP method can create or update the project's Claude settings file.
- The manifest has prepare and prepublish build hooks, but no install, preinstall, or postinstall hook.
Evidence against
- No source evidence showed credential collection, secret transmission, remote command execution, or automatic agent-configuration changes during package installation.
- The discovered agent changes are initiated through an explicit CLI command or callable API.
