A dependency installation can introduce enabled AI-agent commands and deferred npx-executed MCP tools into a consumer project without an explicit setup action. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.2.18 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Npm installation automatically modifies the consumer workspace's OpenCode control surface. It adds agent and command files and creates an enabled MCP configuration when none exists. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-11T15:38:19.943Z - **Finished:** 2026-09-11T15:39:01.583Z - **Download time:** 1014 ms - **Static scan time:** 188 ms - **AI review time:** 40437 ms - **Total time:** 41640 ms The recorded confidence comes from the underlying analysis.

It adds agent and command files and creates an enabled MCP configuration when none exists. - **Trigger:** Installing the package runs its postinstall hook. - **Impact:** A dependency installation can introduce enabled AI-agent commands and deferred npx-executed MCP tools into a consumer project without an explicit setup action. - **Evidence paths:** package.json, scripts/install.js, opencode.tera.example.json - **Review source:** ai\_review - **Reviewed:** 2026-09-11T15:39:01.583Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic workspace-wide OpenCode configuration and agent deployment. - **Attack narrative:** On npm install, postinstall invokes scripts/install.js with INIT\_CWD as the target. The script writes package-controlled agents and commands into .opencode, installs an OpenCode configuration when absent, and enables MCP entries whose commands use npx -y. This silently changes the consumer project's AI-agent control surface and supplies execution-capable tool definitions without an explicit user setup command. - **Rationale:** This is an unconsented postinstall mutation of a foreign AI-agent control surface in the consumer workspace. Its ownership and conflict checks do not remove the risk from creating that surface when it is absent. - **Files touched:** .opencode/agents/\*\*, .opencode/commands/\*\*, .opencode/opencode.json, .opencode/opencode.tera.example.json, .opencode/tera-core.manifest.json, tools/\*\*, tera-system/\*\*, assets/\*\*, project-control/\*\*, .tera/license.state.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs its installer during npm postinstall., The installer selects INIT\_CWD, so npm installation targets the consumer workspace., The postinstall installer populates OpenCode agents, commands, configuration, tools, and other workspace content., The installed OpenCode configuration enables MCP commands through npx without a user setup command. - **Evidence against:** No network or subprocess execution occurs directly in the postinstall script., The installer preserves conflicting unowned files, but still adds a broad agent control surface when absent. ## Affected versions and remediation This report applies to @tera-system/core@0.2.18. - Avoid installing @tera-system/core@0.2.18. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
