The package can cause multiple installed AI tools to load package-supplied instructions and configuration 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:** 0.50.16 - **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 AI-agent commands, skills, plugins, and an OpenCode MCP configuration. It also modifies the consuming repository's .gitignore. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-30T23:50:05.865Z - **Finished:** 2026-08-30T23:51:28.171Z - **Download time:** 759 ms - **Static scan time:** 4542 ms - **AI review time:** 77004 ms - **Total time:** 82306 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically writes and updates global AI-agent commands, skills, plugins, and an OpenCode MCP configuration. It also modifies the consuming repository's .gitignore. - **Trigger:** npm installation, through the postinstall lifecycle hook. - **Impact:** The package can cause multiple installed AI tools to load package-supplied instructions and configuration without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/audit/postinstall.mjs, scripts/shared/install-host-assets.mjs, dist/shared/io/gitignoreArtifacts.js - **Review source:** ai\_review - **Reviewed:** 2026-08-30T23:51:28.171Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic mutation of global AI-agent control surfaces and the consumer project. - **Attack narrative:** A normal npm install invokes scripts/postinstall.mjs, which launches the audit and remediation deployers. The audit deployer writes global Claude and Codex assets, merges an OpenCode configuration containing a package command and MCP entry, and installs a Gemini plugin. The top-level hook additionally selects the install caller's repository and updates its .gitignore. These changes happen automatically rather than through an explicit package command, creating a broad agent-control surface in the user's environment. - **Rationale:** This is concrete, automatic postinstall mutation of foreign AI-agent control surfaces and the consuming project. The lifecycle behavior meets the blocking policy even though no exfiltration or remote payload download was found. - **Files touched:** ~/.claude/commands/audit-code.md, ~/.codex/skills/audit-code/SKILL.md, ~/.config/opencode/opencode.json, ~/.gemini/config/plugins/audit-code/plugin.json, .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 on installation., The install hook deploys global Claude and Codex agent assets under the user's home directory., It merges an OpenCode global configuration that adds a command and MCP entry., It also changes the consuming repository's .gitignore during installation. - **Evidence against:** No HTTP client, download command, or credential-harvesting code was found in the inspected lifecycle and execution files., Child-process helpers use argument arrays with shell disabled for their normal execution path. ## Public findings ### 1.
