The package can change future Claude Code behavior across projects and cause package commands to run during agent events. - **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:** 3.54.0 - **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. An npm postinstall automatically configures a broad Claude Code control surface. No user command or interactive approval is required in unattended installation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-28T05:19:13.163Z - **Finished:** 2026-09-28T05:20:23.630Z - **Download time:** 506 ms - **Static scan time:** 1756 ms - **AI review time:** 68204 ms - **Total time:** 70467 ms The recorded confidence comes from the underlying analysis.

No user command or interactive approval is required in unattended installation. - **Trigger:** Installing the package from npm triggers postinstall. - **Impact:** The package can change future Claude Code behavior across projects and cause package commands to run during agent events. - **Evidence paths:** package.json, src/commands/install.js, src/installer.js - **Review source:** ai\_review - **Reviewed:** 2026-09-28T05:20:23.630Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The lifecycle hook runs the install command, which writes global agent integration assets and registers session and tool hooks. - **Attack narrative:** The package declares a postinstall hook that runs its installer automatically. That installer configures a global Claude Code skill, statusline, session hooks, tool hooks, a global harness block, and document-conversion hooks. The install flow explicitly falls back to automatic defaults when no interactive terminal is available, which is the normal lifecycle-install context. This is an unconsented install-time mutation of a broad AI-agent control surface. - **Rationale:** The automatic lifecycle path modifies global Claude Code configuration and registers future agent hooks without consent. This meets the install-control-surface blocking boundary. - **Files touched:** ~/.claude/CLAUDE.md, ~/.claude/settings.json, ~/.claude/skills/claude-token-saver/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs its install command automatically in a postinstall lifecycle hook., The install command invokes the integration installer, which installs a skill, statusline, and three agent hooks., When unattended, installation uses automatic defaults instead of obtaining interactive consent., The installer adds a global Claude harness and a document-conversion hook to the user's agent configuration. - **Evidence against:** No package-owned unrelated network recipient or credential-export path was established in the inspected install path. ## Affected versions and remediation This report applies to sprag-cli@3.54.0. - Avoid installing sprag-cli@3.54.0. 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.
