The package gains an enabled persistent execution surface in the user's Claude Code configuration and can alter its permission configuration. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.0.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. A global npm installation automatically configures Claude Code without an explicit installer command. It registers and enables the package plugin, writes marketplace records, and configures a command status line in global Claude settings. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-15T16:27:23.435Z - **Finished:** 2026-09-15T16:28:32.223Z - **Download time:** 760 ms - **Static scan time:** 1737 ms - **AI review time:** 66289 ms - **Total time:** 68788 ms The recorded confidence comes from the underlying analysis.

It registers and enables the package plugin, writes marketplace records, and configures a command status line in global Claude settings. - **Trigger:** npm global installation, or a forced postinstall environment setting. - **Impact:** The package gains an enabled persistent execution surface in the user's Claude Code configuration and can alter its permission configuration. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/litclaude-ai.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T16:28:32.223Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-driven Claude Code plugin registration and global settings mutation. - **Attack narrative:** Installing the package globally invokes postinstall, which launches the bundled installer automatically. That installer copies and enables a Claude Code plugin, writes Claude marketplace and plugin registry records, and sets a command-based status line. Its installation flow also includes global Claude permission-rule configuration. This is an unconsented lifecycle mutation of a broad AI-agent control surface. - **Rationale:** The postinstall hook automatically invokes a command that mutates global Claude Code configuration, rather than limiting setup to an explicit user command. This meets the blocking policy for unconsented install-time mutation of a foreign AI-agent control surface. - **Files touched:** ~/.claude/settings.json, ~/.claude/plugins/installed\_plugins.json, ~/.claude/plugins/known\_marketplaces.json, ~/.claude/plugins/cache/litclaude-ai/litclaude/1.0.0, ~/.litclaude/marketplaces/litclaude-ai ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs a postinstall lifecycle script., On global installation, postinstall automatically launches the install command., The install command enables a Claude plugin, registers a marketplace, sets a command status line, and can change global Claude permission rules. - **Evidence against:** The lifecycle script skips ordinary non-global installs unless an environment variable forces it., The installer tracks some owned settings and provides removal logic., No credential harvesting or secret exfiltration was confirmed in the inspected paths. ## Affected versions and remediation This report applies to @litfamily/litclaude@1.0.0. - Avoid installing @litfamily/litclaude@1.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
