Global installation automatically registers LitClaude as a Claude Code plugin and modifies its settings, HUD, registry, and hook surfaces. A later SessionStart can install a cached newer npm version without a direct update command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 94.0% - **Started:** 2026-08-11T09:29:53.459Z - **Finished:** 2026-08-11T09:31:27.911Z - **Download time:** 508 ms - **Static scan time:** 2067 ms - **AI review time:** 91875 ms - **Total time:** 94452 ms ## Security analysis ### Published attack-surface review - **Summary:** Global installation automatically registers LitClaude as a Claude Code plugin and modifies its settings, HUD, registry, and hook surfaces. A later SessionStart can install a cached newer npm version without a direct update command. - **Trigger:** npm global postinstall; then Claude Code SessionStart with a valid cached update candidate - **Impact:** Persistent package-owned hooks and Claude settings changes; upgraded package code may replace the installed plugin. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/litclaude-ai.js, plugins/litclaude/hooks/hooks.json, plugins/litclaude/bin/litclaude-hook.js, plugins/litclaude/lib/automatic-update.mjs, bin/update-notifier.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-11T09:31:27.911Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** first-party Claude plugin setup plus guarded automatic npm update - **Rationale:** The source establishes a real persistent Claude Code control-surface mutation and automatic update path, so it merits a warning. The reviewed implementation is package-aligned, guarded, and lacks a concrete malicious chain. - **Files touched:** ~/.claude/settings.json, ~/.claude/plugins/installed\_plugins.json, ~/.claude/plugins/known\_marketplaces.json, ~/.claude/plugins/cache/litclaude-ai, ~/.litclaude/marketplaces/litclaude-ai, ~/.litclaude/update-notifier - **Network endpoints:** https://registry.npmjs.org/litclaude-ai/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall., scripts/postinstall.mjs invokes install on global installs., bin/litclaude-ai.js writes Claude plugin/settings/HUD state., hooks/hooks.json installs broad Claude Code event hooks., automatic-update.mjs can npm-install cached newer versions at SessionStart., bin/update-notifier.mjs contacts the npm registry. - **Evidence against:** Postinstall skips local, CI, and source-checkout installs by default., Plugin registration is package-owned and uses a local copied payload., Default permission mode is safe; broader rules require mode selection., No credential collection or outbound secret exfiltration found., No eval, shell interpolation, or remote payload execution found in reviewed paths. ## Public findings ### 1.
