The installed hooks run on session and tool-use events and can enforce agent behavior. - **Trigger:** npm install -g @ooples/token-optimizer-mcp - **Impact:** Unconsented persistent control over AI-agent session and tool-call behavior across installed clients. - **Evidence paths:** package.json, scripts/postinstall.cjs, install-hooks.sh, install-hooks.ps1, scripts/wire-hooks.mjs, hooks-core/wire.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-10T07:17:21.016Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-launched broad AI-agent configuration and hook injection - **Attack narrative:** On global installation, postinstall launches a platform installer without an explicit setup command. It copies hook code, writes Claude Code settings, marks workspace trust, and configures MCP entries for multiple unrelated AI products; the hooks then run at session start and before agent tool use. This is an unconsented install-time mutation of broad AI-agent control surfaces. - **Rationale:** The package has a concrete unconsented postinstall chain that changes foreign and broad AI-agent configuration surfaces. Its CI/local-install guard does not mitigate the global-install behavior. - **Files touched:** scripts/postinstall.cjs, install-hooks.sh, install-hooks.ps1, scripts/wire-hooks.mjs, hooks-core/wire.mjs, ~/.claude/settings.json, ~/.claude.json, ~/.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:** package.json runs postinstall., scripts/postinstall.cjs automatically runs installer for global installs., install-hooks.sh writes ~/.claude/settings.json hook commands., install-hooks.sh adds MCP entries to Claude Desktop, Cursor, Cline, Copilot, and Windsurf configs., hooks-core/wire.mjs installs SessionStart, PreToolUse, and PreCompact command hooks., plugin/hooks/pretooluse-router.mjs enforces decisions over agent tool calls. - **Evidence against:** Postinstall skips CI and non-global dependency installs., plugin/hooks/lib/harvest.mjs requires explicit opt-in before remote digest transmission. ## Public findings ### 1.
