tina4-nodejs@3.13.111
Tina4 for Node.js/TypeScript - native TypeScript conventions and shared Tina4 contracts
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package provides an explicit user-invoked mechanism that changes a broad AI-agent control surface and downloads its instruction files remotely. There is no automatic registry-install trigger or confirmed credential exfiltration in the inspected evidence.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
User runs tina4nodejs ai, including with --all.
Impact
Downloaded instructions can affect future Claude Code sessions in the current and other projects.
Mechanism
Downloads and writes AI-agent skill files to project and global Claude directories.
AI rationale
The package provides an explicit user-invoked mechanism that changes a broad AI-agent control surface and downloads its instruction files remotely. There is no automatic registry-install trigger or confirmed credential exfiltration in the inspected evidence.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The CLI exposes an explicit ai command that installs AI assistant context files.
- The installer downloads skill files to both the selected project and the user's global Claude skills directory.
- Skill content is fetched from a Tina4 GitHub repository URL.
- The published core bundle contains the same dual project/global installation logic.
Evidence against
- The manifest has no preinstall, install, or postinstall hook; its prepare script only builds the package.
- The AI configuration mutation requires the user to invoke the ai command or pass --all; no automatic activation was found.
- No confirmed credential transmission to an unrelated endpoint was found in the inspected paths.

Cross File Remote Execution Context
Source spawns a local helper that also contains network and dynamic execution context; review data flow before blocking.
