Agent settings and background behavior are changed during installation without provider-specific consent. - **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:** 0.1.2 - **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. The automatic global-install lifecycle hook makes broad AI-agent configuration changes across three providers and installs recurring background behavior. This meets the policy for blocking unconsented install-time mutation of a broad AI-agent control surface. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-12T12:44:28.421Z - **Finished:** 2026-10-12T12:44:56.009Z - **Download time:** 515 ms - **Static scan time:** 105 ms - **AI review time:** 26967 ms - **Total time:** 27588 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:** Global installation automatically modifies AI-agent configuration for three providers and sets up recurring Codex synchronization. - **Trigger:** Installing the package globally through npm triggers postinstall. - **Impact:** Agent settings and background behavior are changed during installation without provider-specific consent. - **Evidence paths:** package.json, setup/postinstall.mjs, setup/setup.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-12T12:44:56.009Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook runs setup for all providers, adds agent hooks and status-line configuration, and installs a recurring Codex LaunchAgent without a separate setup command. - **Attack narrative:** A global npm installation invokes postinstall, which configures Claude, Codex, and Gemini automatically. The setup writes hooks into their settings and installs a recurring Codex LaunchAgent. These are broad agent-control changes triggered during package installation, without requiring a separate setup command. - **Rationale:** The automatic global-install lifecycle hook makes broad AI-agent configuration changes across three providers and installs recurring background behavior. This meets the policy for blocking unconsented install-time mutation of a broad AI-agent control surface. - **Files touched:** ~/.claude/settings.json, ~/.codex/hooks.json, ~/.gemini/settings.json, ~/Library/LaunchAgents/com.ai-usage-meter.codex-sync.plist ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook runs automatically and only skips setup when the package is not installed globally; global installation starts setup for all integrations., Setup writes hooks and status-line configuration into Claude, Codex, and Gemini settings, and creates a Codex LaunchAgent for recurring background sync. - **Evidence against:** Local installations exit the postinstall hook before configuration begins., Setup preserves existing settings and backs them up before writing changes. ## Affected versions and remediation This report applies to ai-usage-meter@0.1.2. - Avoid installing ai-usage-meter@0.1.2. 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.
