Package-controlled prompts and permissions become available in unrelated agent hosts without an explicit setup command. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.50.13 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically writes and updates global Codex, Claude, OpenCode, and Gemini agent assets. It also modifies the consuming repository's .gitignore. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-29T23:59:08.404Z - **Finished:** 2026-08-30T00:00:22.938Z - **Download time:** 777 ms - **Static scan time:** 3644 ms - **AI review time:** 70111 ms - **Total time:** 74534 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically writes and updates global Codex, Claude, OpenCode, and Gemini agent assets. It also modifies the consuming repository's .gitignore. - **Trigger:** npm installation executes postinstall - **Impact:** Package-controlled prompts and permissions become available in unrelated agent hosts without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/remediate/postinstall.mjs, scripts/shared/install-host-assets.mjs, dist/shared/io/gitignoreArtifacts.js - **Review source:** ai\_review - **Reviewed:** 2026-08-30T00:00:22.938Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic mutation of global AI-agent commands, skills, plugins, and configuration - **Attack narrative:** On npm installation, the package runs two postinstall deployers. They copy package-controlled skills and prompts into global Codex and Claude locations, add plugins for Gemini, and merge commands and permissions into OpenCode's global configuration. The same lifecycle path writes a managed block into the consumer repository's .gitignore. These changes occur without an explicit user setup command and affect foreign AI-agent control surfaces. - **Rationale:** The automatic postinstall hook makes broad, persistent changes to multiple global AI-agent control surfaces and the consumer project. This meets the install-hook abuse policy even though no secret exfiltration was found. - **Files touched:** scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/remediate/postinstall.mjs, scripts/shared/install-host-assets.mjs, ~/.codex/skills/audit-code/SKILL.md, ~/.codex/skills/remediate-code/SKILL.md, ~/.claude/commands/audit-code.md, ~/.config/opencode/opencode.json, ~/.gemini/config/plugins/audit-code/plugin.json, consumer repository/.gitignore ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall hook automatically., The install hook launches both agent-asset installers., The audit installer writes global Codex skills and prompts into the user home directory., The installers merge commands and permissions into the global OpenCode configuration., Shared helpers create parent directories and overwrite generated files during installation., The hook also changes the consuming repository's .gitignore. - **Evidence against:** No credential harvesting or secret exfiltration was found in the inspected install scripts., Runtime analyzer downloads use checksum verification and are separate from the install hook., package.json has no runtime dependency on audit-tools itself. ## Public findings ### 1.
