Subsequent agent sessions receive package-directed instructions and hooks, while Claude gains permission to execute the package's team-sync command without prompting. - **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:** 0.3.0-beta.5 - **Selected version is latest:** Yes - **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. Installing the package automatically modifies the consumer project's shared AI-agent instructions, hooks, and command permissions. These changes reach Claude and Codex control surfaces without an installation-time consent prompt. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-06T12:02:47.076Z - **Finished:** 2026-10-06T12:03:40.586Z - **Download time:** 771 ms - **Static scan time:** 1108 ms - **AI review time:** 51631 ms - **Total time:** 53510 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:** Installing the package automatically modifies the consumer project's shared AI-agent instructions, hooks, and command permissions. These changes reach Claude and Codex control surfaces without an installation-time consent prompt. - **Trigger:** A local npm installation into the project's node\_modules when the installer skip conditions are absent. - **Impact:** Subsequent agent sessions receive package-directed instructions and hooks, while Claude gains permission to execute the package's team-sync command without prompting. - **Evidence paths:** package.json, postinstall.mjs, init-project.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-06T12:03:40.586Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The postinstall hook calls project initialization, which appends instructions, installs skills, merges prompt hooks, and adds command permission rules. - **Attack narrative:** A normal local npm installation activates postinstall.mjs. It initializes the consumer project without asking for consent, appending instructions to AGENTS.md and CLAUDE.md and installing agent skills. Initialization also merges prompt hooks into Claude and Codex configuration and adds Claude command permissions for team synchronization. The behavior therefore changes broad agent control surfaces automatically during installation. - **Rationale:** Inspected source establishes automatic, unconsented postinstall mutation of shared AI-agent instructions and configuration, meeting the blocking policy. Environment skips and preservation safeguards limit scope but do not authorize these changes. - **Files touched:** AGENTS.md, CLAUDE.md, .agents/skills/brainforge-start/SKILL.md, .claude/skills/brainforge-start/SKILL.md, .claude/settings.json, .codex/hooks.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json automatically runs postinstall.mjs, which calls project initialization without a consent prompt., init-project.mjs appends agent instructions to the consumer project's AGENTS.md and CLAUDE.md and installs skills for multiple agents., init-project.mjs adds permission rules allowing its team-sync command to run without prompting., Project initialization installs Claude and Codex prompt hooks by default and writes the merged agent configuration. - **Evidence against:** Setup skips CI, global installs, and installations outside the consumer project's node\_modules., The installer preserves existing instruction text and rejects symbolic-link destinations; these safeguards do not provide consent for agent configuration changes. ## Affected versions and remediation This report applies to brainforge-kit@0.3.0-beta.5. - Avoid installing brainforge-kit@0.3.0-beta.5. 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.
