tina4-nodejs@3.13.131
Tina4 for Node.js/TypeScript - native TypeScript conventions and shared Tina4 contracts
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is an explicit-user-command AI-agent configuration capability with global impact, so it warrants a warning. The inspected manifest has no automatic install lifecycle hook and no concrete credential-exfiltration path was confirmed.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
The user runs `tina4nodejs ai`, selects Claude Code, or runs it with `--all`.
Impact
Remote skill content can influence AI assistants in the project and in other user projects.
Mechanism
Downloads and writes AI-agent context and skill files, including a global Claude directory.
AI rationale
This is an explicit-user-command AI-agent configuration capability with global impact, so it warrants a warning. The inspected manifest has no automatic install lifecycle hook and no concrete credential-exfiltration path was confirmed.

Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The explicit `ai` CLI command installs AI assistant context files.
- The installer downloads skill content and writes it to both the project and the user's global Claude skills directory.
- The installer can invoke pip to install an additional Tina4 AI package when selected.
Evidence against
- No npm preinstall, install, or postinstall hook is present; `prepare` only runs the package build.
- The AI client sends caller-provided prompts only to configured local, OpenAI, or Anthropic endpoints; no credential harvesting or fixed unofficial credential gateway was found.
