Subsequent AI-agent sessions in the project can be steered by configuration written during dependency installation. - **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. The manifest activates an install hook that automatically writes behavior-bearing instructions into multiple consumer AI-agent configuration locations. This meets the policy for blocking unconsented install-time control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-17T01:02:24.355Z - **Finished:** 2026-10-17T01:03:00.012Z - **Download time:** 764 ms - **Static scan time:** 133 ms - **AI review time:** 34759 ms - **Total time:** 35657 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:** The npm postinstall hook automatically changes project instructions and AI-tool configuration. This gives package-supplied directives influence over multiple consumer AI agents without a separate setup action. - **Trigger:** Installing the package in an external project with npm, which runs its postinstall hook. - **Impact:** Subsequent AI-agent sessions in the project can be steered by configuration written during dependency installation. - **Evidence paths:** package.json, bin/postinstall.js, bin/harness-bridge.js - **Review source:** ai\_review - **Reviewed:** 2026-10-17T01:03:00.012Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook calls setupGovernance, which writes AGENTS.md and redirects for Claude, Cursor, Gemini, and Copilot that instruct those tools to follow AGENTS.md and load bundled skills. - **Attack narrative:** Installing the package in an external project activates its postinstall hook, which calls setupGovernance without an affirmative setup prompt. The routine writes package-provided instructions into AGENTS.md and several AI-agent configuration files, directing those agents to follow the generated rules and load bundled skills. This is an unconsented install-time change to a broad AI-agent control surface. - **Rationale:** The manifest activates an install hook that automatically writes behavior-bearing instructions into multiple consumer AI-agent configuration locations. This meets the policy for blocking unconsented install-time control-surface mutation. - **Files touched:** AGENTS.md, CLAUDE.md, .cursorrules, .gemini/rules/project.md, .github/copilot-instructions.md ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for policy risk:** The manifest runs bin/postinstall.js as an npm postinstall hook., The hook targets an external project from INIT\_CWD and automatically calls setupGovernance., The setup writes generated governance instructions to the project root AGENTS.md., The generated redirect tells several AI tools to follow AGENTS.md and load package skills., The setup writes those redirects into Claude, Cursor, Gemini, and Copilot configuration files., The entrypoint describes bridging AI harnesses to AGENTS.md. ## Affected versions and remediation This report applies to @goobit/ai@1.0.0. - Avoid installing @goobit/ai@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.
