It also attempts workspace-trust and MCP-server configuration across detected tools. - **Trigger:** npm global install invokes postinstall - **Impact:** Unconsented persistent interception of Claude Code tool/session events and modification of foreign AI-agent control surfaces. - **Evidence paths:** package.json, scripts/postinstall.cjs, install-hooks.sh, install-hooks.ps1, scripts/wire-hooks.mjs, hooks-core/wire.mjs, plugin/hooks/hooks.json - **Review source:** ai\_review - **Reviewed:** 2026-08-05T11:35:30.750Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-launched cross-agent hook/configuration mutation - **Attack narrative:** During a global npm install, postinstall launches a platform installer. The installer copies hook modules, wires them into Claude Code SessionStart/PreToolUse/PreCompact events, accepts workspace trust, and configures MCP entries for several AI tools without a separate user command or confirmation. This is an unconsented install-time mutation of broad, foreign AI-agent control surfaces. - **Rationale:** The lifecycle behavior meets the block boundary: postinstall automatically mutates persistent Claude Code and other AI-tool control/configuration surfaces. Opt-in harvest networking does not negate the install-time control-surface takeover. - **Files touched:** $HOME/.claude-global/hooks/token-optimizer, $HOME/.claude/settings.json, $HOME/.claude.json, $HOME/.config/Claude/claude\_desktop\_config.json, $HOME/.cursor/mcp.json, .vscode/mcp.json - **Network endpoints:** https://api.anthropic.com/v1/messages ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall, scripts/postinstall.cjs runs installer on global npm install, install-hooks.sh automatically writes Claude hooks/settings, install-hooks.sh changes workspace trust and AI-tool MCP configs, hooks-core/wire.mjs installs SessionStart, PreToolUse, PreCompact commands - **Evidence against:** Harvest network call requires explicit opt-in and API key, plugin/hooks/lib/harvest.mjs defaults to an Anthropic endpoint only after opt-in, Installer copies shipped hooks; no remote payload download found ## Public findings ### 1.
