It also accepts Claude workspace trust without a separate user confirmation. - **Trigger:** Interactive global installation of the package. - **Impact:** The package gains persistent execution through agent hooks and can influence future agent sessions and tool routing. - **Evidence paths:** package.json, scripts/postinstall.cjs, install-hooks.sh, install-hooks.ps1, scripts/wire-hooks.mjs, plugin/hooks/session-start.mjs, plugin/hooks/pretooluse-router.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-28T21:36:10.615Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-driven mutation of AI-agent hooks, settings, MCP configurations, and workspace trust. - **Attack narrative:** Installing this package globally invokes postinstall, which executes a platform installer. The installer copies persistent hooks into the user's Claude hook directory, changes Claude settings, adds the package server to multiple unrelated AI-agent configuration files, and marks the current Claude workspace trusted. The Windows installer can also change PowerShell execution policy. These changes occur as an install side effect rather than through an explicit setup command. - **Rationale:** This is unconsented postinstall mutation of broad, foreign AI-agent control surfaces, including workspace trust. The lifecycle behavior is concrete and sufficient to block even though the inspected path did not show credential exfiltration. - **Files touched:** package.json, scripts/postinstall.cjs, install-hooks.sh, install-hooks.ps1, plugin/hooks/\*\*, $HOME/.claude-global/hooks/token-optimizer/\*\*, $HOME/.claude/settings.json, $HOME/.claude.json, $HOME/.cursor/mcp.json, .vscode/mcp.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package registers a postinstall lifecycle hook., On global installation, postinstall runs the bundled shell or PowerShell installer automatically., The installer copies hooks into the user's global Claude hooks directory and rewrites Claude settings., It injects an MCP server entry into detected Claude, Cursor, Cline, Copilot, and Windsurf configuration files., The installer marks the current Claude workspace as trusted; the Windows path also lowers the current user's PowerShell execution policy. - **Evidence against:** The automatic hook path skips CI and non-global dependency installs., No credential exfiltration or relevant network request was found in the inspected install path. ## Public findings ### 1.
