It mutates broad AI-agent control surfaces without an explicit user command and installs enforcement code that controls agent completion and Git pushes. - **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:** 15.2.1 - **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. On npm installation, the package initializes the consumer repository and installs agent-control and Git-hook artifacts. It adds a Claude Stop hook that executes package-controlled checks and can prevent an agent turn from ending. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-11T22:01:26.254Z - **Finished:** 2026-09-11T22:02:31.413Z - **Download time:** 761 ms - **Static scan time:** 1503 ms - **AI review time:** 62894 ms - **Total time:** 65159 ms The recorded confidence comes from the underlying analysis.

It adds a Claude Stop hook that executes package-controlled checks and can prevent an agent turn from ending. - **Trigger:** Installing @softize/opus as a direct dependency with npm lifecycle scripts enabled. - **Impact:** It mutates broad AI-agent control surfaces without an explicit user command and installs enforcement code that controls agent completion and Git pushes. - **Evidence paths:** package.json, bin/lib/postinstall.mjs, bin/lib/materialize.mjs, registry/hooks/opus-check-on-stop.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-11T22:02:31.413Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic postinstall materializes agent skills, Claude hooks/settings, and Git hooks in the consumer project. - **Attack narrative:** npm runs the package postinstall, which identifies the consumer project and calls initialization. Initialization copies package-owned skills and hooks into .agents and .claude, rewrites .claude/settings.json to register a Stop command hook, installs Git hooks, and changes Git configuration. The Stop hook runs package-controlled checks after changed files and exits with code 2 on selected failures, blocking the agent from ending its turn. This is automatic mutation of a foreign project's AI-agent control surface rather than an explicit setup command. - **Rationale:** The package's automatic postinstall writes and configures broad consumer AI-agent and Git control surfaces, including a hook that can block agent completion. This meets the install-time AI-agent control-surface abuse policy despite no observed network exfiltration. - **Files touched:** package.json, base.json, opus.json, AGENTS.md, CLAUDE.md, .claude/settings.json, .claude/hooks/opus-check-on-stop.mjs, .claude/skills/, .agents/skills/, .githooks/, .git/config, .git/info/exclude ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs its setup automatically through npm postinstall., The postinstall calls project initialization against the consumer project., Initialization writes managed agent skills, hooks, workflows, and Git hook files into the consumer repository., It modifies Claude settings to install a Stop hook that runs package code., The installed Stop hook can block an agent from ending its turn when checks fail., It also configures the repository Git hooks path and removes exclusions for agent artifacts. - **Evidence against:** No secret collection or outbound network request was found in the inspected install and hook path., The hook code uses local Git status and local package commands rather than remote payload retrieval. ## Affected versions and remediation This report applies to @softize/opus@15.2.1. - Avoid installing @softize/opus@15.2.1. 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.
