A dependency install can activate package-supplied agent behavior and an extra browser-capable plugin in the consumer project. - **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:** 0.8.10 - **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 changes the consuming project's OpenCode control surface. It installs agent resources and plugin code, then registers an additional browser plugin. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-04T04:03:32.265Z - **Finished:** 2026-09-04T04:04:24.594Z - **Download time:** 510 ms - **Static scan time:** 416 ms - **AI review time:** 51401 ms - **Total time:** 52329 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically changes the consuming project's OpenCode control surface. It installs agent resources and plugin code, then registers an additional browser plugin. - **Trigger:** npm installation runs the postinstall lifecycle hook. - **Impact:** A dependency install can activate package-supplied agent behavior and an extra browser-capable plugin in the consumer project. - **Evidence paths:** package.json, scripts/install.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-04T04:04:24.594Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies agent assets and rewrites OpenCode plugin configuration. - **Attack narrative:** The package declares a postinstall hook that runs without a separate setup command. The installer resolves INIT\_CWD to the consuming project, copies agents, commands, skills, and plugin code into its .opencode directory, and rewrites opencode.json to register the package plus opencode-browser. This is an unconsented install-time mutation of a foreign AI-agent control surface. - **Rationale:** The automatic lifecycle hook makes broad OpenCode configuration and plugin changes in the consumer project, including registration of an additional browser plugin. This meets the install-hook abuse policy even though no exfiltration or network request was found. - **Files touched:** opencode.json, .opencode/commands, .opencode/agents, .opencode/skills, .opencode/plugins/impm, .opencode/plugins/impm.js, .opencode/package.json, .opencode/impm-manifest.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The npm postinstall hook automatically runs the installer., The installer selects the consuming project's INIT\_CWD as its target., It copies packaged agents, commands, skills, and a local plugin into the target's OpenCode directory., It overwrites the consumer's OpenCode configuration and registers both this package and opencode-browser. - **Evidence against:** The installer contains no network request or secret-exfiltration logic., No runtime dependency on another release of this package is declared. ## Public findings ### 1.
