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 install this package’s Claude plugin and register its local marketplace. This is an agent extension lifecycle capability; no independent malicious action was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-08T16:54:03.619Z - **Finished:** 2026-10-08T16:54:41.311Z - **Download time:** 2044 ms - **Static scan time:** 2677 ms - **AI review time:** 32970 ms - **Total time:** 37692 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 install this package’s Claude plugin and register its local marketplace. This is an agent extension lifecycle capability; no independent malicious action was identified. - **Trigger:** Global npm installation, unless an environment opt-out, CI condition, or source checkout condition skips the hook. - **Impact:** Claude configuration is changed to load the package-owned plugin and marketplace. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/litclaude-ai.js - **Review source:** ai\_review - **Reviewed:** 2026-10-08T16:54:41.311Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook launches the package CLI install command, which copies its own plugin and writes marketplace metadata and Claude registration. - **Rationale:** The postinstall hook can make package-owned Claude plugin changes during global installation without a separate CLI invocation. This is a warning-level agent extension lifecycle risk, with no inspected evidence supporting a block. - **Files touched:** package.json, scripts/postinstall.mjs, bin/litclaude-ai.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json declares a postinstall hook that runs scripts/postinstall.mjs., The hook runs the package CLI install command on global installs unless disabled or skipped by environment conditions., That install copies this package’s Claude plugin and registers its local marketplace in Claude configuration., The inspected flagged locations identify Claude configuration paths and tests for the postinstall plugin setup; they show no separate foreign extension target. - **Evidence against:** No inspected source showed credential collection, exfiltration, or remote payload execution., Automatic updates use a temporary npm config file explicitly written without credentials. ## Affected versions and remediation This report applies to @litfamily/litclaude@1.0.19. - Review the evidence and your use of @litfamily/litclaude@1.0.19 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.
