A global npm install automatically registers the packaged LitClaude extension with Claude Code and installs a HUD command. This is a first-party, package-scoped Claude extension lifecycle action; no exfiltration or remote payload chain was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-03T10:08:57.908Z - **Finished:** 2026-08-03T10:09:38.581Z - **Download time:** 768 ms - **Static scan time:** 478 ms - **AI review time:** 39426 ms - **Total time:** 40673 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically registers the packaged LitClaude extension with Claude Code and installs a HUD command. This is a first-party, package-scoped Claude extension lifecycle action; no exfiltration or remote payload chain was confirmed. - **Trigger:** Global npm install (unless skipped), or explicit litclaude install. - **Impact:** Changes Claude Code configuration and enables package-provided hooks for future Claude sessions. - **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/public-source-reader/validator.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-03T10:09:38.581Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Copies and registers a Claude Code plugin, hooks, marketplace entry, and status-line command. - **Rationale:** This is a guarded but automatic first-party Claude extension setup, which warrants a warning under the lifecycle policy. It is not concrete malicious behavior. - **Files touched:** $CLAUDE\_CONFIG\_DIR/plugins/installed\_plugins.json, $CLAUDE\_CONFIG\_DIR/plugins/known\_marketplaces.json, $CLAUDE\_CONFIG\_DIR/settings.json, $CLAUDE\_CONFIG\_DIR/plugins/cache/litclaude-ai/litclaude/0.3.29, $LITCLAUDE\_HOME/marketplaces/litclaude-ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json invokes postinstall., scripts/postinstall.mjs auto-runs install for global installs., bin/litclaude-ai.js writes Claude plugin registry, marketplace, settings, and statusLine., Installed plugin hooks execute on Claude session and tool events. - **Evidence against:** Postinstall skips CI, source checkouts, and non-global installs unless explicitly forced., Writes are scoped to the LitClaude plugin, marketplace, and managed HUD state., No credential harvesting or unsolicited network activity found., Public HTTP fetching is an explicit CLI/MCP action with private-host checks. ## Public findings ### 1.
