It can add enabled agent tooling and package-managed files to the consumer workspace 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:** 0.2.20 - **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 creates an OpenCode configuration in the consumer project when one is absent. That configuration enables MCP commands which invoke npx with automatic installation, and postinstall fetches and applies vendor-signed workspace content. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-04T06:48:55.282Z - **Finished:** 2026-09-04T06:50:33.310Z - **Download time:** 779 ms - **Static scan time:** 164 ms - **AI review time:** 97084 ms - **Total time:** 98028 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically creates an OpenCode configuration in the consumer project when one is absent. That configuration enables MCP commands which invoke npx with automatic installation, and postinstall fetches and applies vendor-signed workspace content. - **Trigger:** npm installation, through the postinstall lifecycle hook. - **Impact:** It can add enabled agent tooling and package-managed files to the consumer workspace without an explicit setup command. - **Evidence paths:** package.json, scripts/install.js, opencode.tera.example.json - **Review source:** ai\_review - **Reviewed:** 2026-09-04T06:50:33.310Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic OpenCode control-surface creation and remote bundle application. - **Attack narrative:** The postinstall hook runs against INIT\_CWD, the consumer project. It creates .opencode/opencode.json if absent and populates it with enabled MCP entries that execute npx -y commands. In the same automatic lifecycle it fetches a remote signed bundle and applies its files to OpenCode agent and command directories and other workspace paths. Although it avoids replacing an existing configuration and verifies bundle signatures, the vendor controls the signer and the install still creates a foreign AI-agent control surface without an explicit user setup action. - **Rationale:** This is a concrete unconsented postinstall mutation of a consumer OpenCode control surface, coupled with remote vendor-controlled content application. Signature verification does not remove the supply-chain control exercised by the package publisher. - **Files touched:** .opencode/opencode.json, .opencode/opencode.tera.example.json, .opencode/agents/, .opencode/commands/, tera-system/, tools/, project-control/ - **Network endpoints:** https://teranoo.com/api/tera-system/bundle ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** A postinstall hook automatically runs the installer., The installer targets npm's initiating project and creates its OpenCode configuration when absent., The installed OpenCode configuration enables local MCP commands that use npx with automatic package installation., Postinstall downloads a vendor-controlled bundle and writes its files into the target workspace. - **Evidence against:** The installer preserves an existing OpenCode configuration rather than overwriting it., Downloaded bundles are checked with an embedded Ed25519 public key before application. ## Public findings ### 1.
