Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. A global npm postinstall can register this package's Claude Code plugin and HUD automatically. This is first-party agent extension setup and presents a lifecycle configuration risk. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-08T16:53:47.887Z - **Finished:** 2026-10-08T16:54:24.879Z - **Download time:** 1543 ms - **Static scan time:** 2829 ms - **AI review time:** 32617 ms - **Total time:** 36992 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A global npm postinstall can register this package's Claude Code plugin and HUD automatically. This is first-party agent extension setup and presents a lifecycle configuration risk. - **Trigger:** Installing the package globally through npm, unless skipped or running in CI; an environment flag can force setup. - **Impact:** Claude Code may load the package's plugin and HUD without a separate install command. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/litclaude-ai.js - **Review source:** ai\_review - **Reviewed:** 2026-10-08T16:54:24.879Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall launches the package's install command, which writes plugin registration and HUD settings under the user's Claude configuration directory. - **Rationale:** The postinstall can automatically configure Claude Code during global installation, creating a first-party agent extension lifecycle risk. The inspected behavior is limited to the package's own plugin and HUD, so the evidence supports a warning rather than a block. - **Files touched:** package.json, scripts/postinstall.mjs, bin/litclaude-ai.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs a postinstall script. That script skips ordinary local installs, but on global installs it launches the package's install command., The install command registers the package's Claude Code plugin in Claude settings and marketplace records., The install path targets the user's Claude configuration directory; automatic updates also have a dedicated package-managed update location., The package's behavior probe describes forced postinstall as registering the plugin and HUD in an isolated Claude home. - **Evidence against:** The postinstall skips CI and non-global installs unless explicitly forced., The reviewed source shows first-party LitClaude plugin and HUD setup, with no unrelated network recipient or credential forwarding established. ## Affected versions and remediation This report applies to @litfamily/litclaude@1.0.13. - Review the evidence and your use of @litfamily/litclaude@1.0.13 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
