The package can alter future agent behavior across the user's Claude, Codex, OpenCode, and Gemini environments. - **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:** 0.50.12 - **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 skills, commands, plugins, and configuration into several global AI-agent control surfaces. These changes occur without an explicit setup command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-29T19:36:35.379Z - **Finished:** 2026-08-29T19:37:38.202Z - **Download time:** 512 ms - **Static scan time:** 3601 ms - **AI review time:** 58709 ms - **Total time:** 62823 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically writes skills, commands, plugins, and configuration into several global AI-agent control surfaces. These changes occur without an explicit setup command. - **Trigger:** npm installation runs the postinstall hook. - **Impact:** The package can alter future agent behavior across the user's Claude, Codex, OpenCode, and Gemini environments. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/remediate/postinstall.mjs, scripts/shared/install-host-assets.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-29T19:37:38.202Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic global AI-agent asset and configuration deployment. - **Attack narrative:** The npm postinstall hook starts two deployers. They copy package-provided prompts and skills into global Claude and Codex locations, merge OpenCode configuration, and add global Gemini and Claude plugins. The shared writer creates parent directories and overwrites existing generated assets. Because these are automatic install-time writes to broad third-party AI-agent control surfaces rather than an explicit user setup command, the package can influence later agent sessions. - **Rationale:** The package performs unconsented postinstall mutation of multiple global AI-agent control surfaces. This meets the install-control-surface block policy even though no credential theft or install-time network activity was found. - **Files touched:** .gitignore, ~/.claude/commands/audit-code.md, ~/.claude/plugins/marketplaces/claude-plugins-official/external\_plugins/audit-code, ~/.codex/skills/audit-code/SKILL.md, ~/.config/opencode/opencode.json, ~/.gemini/config/plugins/audit-code ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Automatic postinstall runs both host-asset deployers., The audit deployer writes global Claude and Codex command assets., It merges an OpenCode global configuration during installation., Shared helpers create directories and overwrite generated files., The install also creates global Gemini and Claude plugins. - **Evidence against:** No runtime self-dependency is declared., No install-time network request, credential collection, or payload download was found. ## Public findings ### 1.
