tianshu-tui@2.13.0: Clean npm security report (Allow) | LPM Firewall

Decision evidence

public snapshot

AI called this Clean at 86.0% confidence as Benign with low false-positive risk.

Evidence for block

package.json defines postinstall: patch-package || node -e 1
CLI includes user-invoked tools that can import URLs/GitHub/local paths into .rivet/external and spawn git/curl with approval
Runtime can copy Claude skills into .rivet/skills via /skill install/import, a user-invoked command

Evidence against

No patches/ directory or package files for patch-package to apply were present
Postinstall does not run package code; fallback is inert node -e 1
Agent/CLI network endpoints are package-aligned: OpenAI OAuth/API, npm registry, GitHub releases, user-provided MCP/import URLs
Child_process usage is tied to CLI functions such as git, shell tools, update, open_path, and MCP management rather than install/import-time exfiltration
No evidence of lifecycle writes to .claude, .mcp.json, Codex/Cursor settings, shell startup files, VCS hooks, or OS persistence
