A package-controlled signing key can authorize future agent and command content in the consumer project; the injected MCP configuration can run additional packages through npx. - **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:** 0.2.2 - **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 mutates the consumer workspace's OpenCode control surface. It installs an enabled MCP configuration and then downloads signed vendor-controlled content into OpenCode agent and command directories. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-28T20:09:30.791Z - **Finished:** 2026-08-28T20:10:25.615Z - **Download time:** 761 ms - **Static scan time:** 143 ms - **AI review time:** 53919 ms - **Total time:** 54824 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package mutates the consumer workspace's OpenCode control surface. It installs an enabled MCP configuration and then downloads signed vendor-controlled content into OpenCode agent and command directories. - **Trigger:** npm installation runs the postinstall hook. - **Impact:** A package-controlled signing key can authorize future agent and command content in the consumer project; the injected MCP configuration can run additional packages through npx. - **Evidence paths:** package.json, scripts/install.js, scripts/lib/bundle.mjs, opencode.tera.example.json - **Review source:** ai\_review - **Reviewed:** 2026-08-28T20:10:25.615Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic OpenCode configuration injection and remote bundle deployment. - **Attack narrative:** On npm installation, the postinstall hook runs against the consumer workspace. If no OpenCode configuration exists, it writes one that enables MCP commands using npx. The same lifecycle execution fetches a vendor-signed remote bundle and writes its contents into OpenCode agent and command directories. Although signature verification exists, the package author controls the trust root, so this is an unconsented install-time path to deploy future AI-agent behavior into another project. - **Rationale:** This is a concrete unconsented postinstall mutation of a consumer AI-agent control surface, combined with remote vendor-authorized content deployment. Signature verification does not remove the risk because the package supplies the public key and controls the signing authority. - **Files touched:** .opencode/opencode.json, .opencode/opencode.tera.example.json, .opencode/tera-core.manifest.json, .opencode/agents/, .opencode/commands/, tera-system/, tools/, .tera/sync.state.json, .tera/license.state.json - **Network endpoints:** https://teranoo.com/api/tera-system/bundle, https://teranoo.com/api/license ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall hook automatically runs the workspace installer., The installer creates a new OpenCode configuration when one is absent., That configuration enables MCP entries which invoke npx packages., Installation fetches a remotely supplied bundle and writes its agent and command files into the project., The remote bundle writer overwrites destination files without checking package ownership. - **Evidence against:** The bundle verifier checks an Ed25519 signature and file hashes before applying it., No runtime self-dependency is declared., The inspected installer does not harvest arbitrary files or environment variables for exfiltration. ## Public findings ### 1.
