An install can alter an AI agent's available instructions, commands, and executable tool channels 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:** 0.2.11 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. A postinstall hook modifies the consumer workspace and creates an enabled OpenCode control surface. It installs agent instructions and commands, and writes a configuration that runs external MCP packages through npx. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-31T20:20:47.512Z - **Finished:** 2026-08-31T20:21:42.276Z - **Download time:** 762 ms - **Static scan time:** 128 ms - **AI review time:** 53873 ms - **Total time:** 54764 ms ## Security analysis ### Published attack-surface review - **Summary:** A postinstall hook modifies the consumer workspace and creates an enabled OpenCode control surface. It installs agent instructions and commands, and writes a configuration that runs external MCP packages through npx. - **Trigger:** Installing the npm package. - **Impact:** An install can alter an AI agent's available instructions, commands, and executable tool channels without an explicit setup command. - **Evidence paths:** package.json, scripts/install.js, opencode.tera.example.json - **Review source:** ai\_review - **Reviewed:** 2026-08-31T20:21:42.276Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic consumer-project mutation and enabled MCP command injection. - **Attack narrative:** npm invokes scripts/install.js during postinstall. The script resolves the consumer project from INIT\_CWD, copies package-provided agents and commands into .opencode, and creates .opencode/opencode.json when absent. That configuration enables MCP entries whose commands use npx, creating executable external tool channels in the consumer's AI-agent environment. Although the installer avoids replacing a differing existing configuration, the automatic creation and broad control-surface mutation occur without an explicit user setup action. - **Rationale:** This is an unconsented postinstall mutation of a consumer AI-agent control surface, with enabled npx-backed tool commands. It meets the install-control-surface block policy despite the absence of observed secret theft. - **Files touched:** .opencode/agents, .opencode/commands, .opencode/opencode.json, .opencode/opencode.tera.example.json, tera-system, tools, assets, .opencode/tera-core.manifest.json, .tera/license.state.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs its installer automatically through postinstall., The installer targets the consuming project via INIT\_CWD., Install-time code copies agents, commands, assets, and an OpenCode configuration into the project., The installed configuration enables MCP commands that use npx to obtain and run external packages. - **Evidence against:** The installer preserves a pre-existing OpenCode configuration when it differs., No credential exfiltration or explicit network request occurs in the lifecycle script. ## Public findings ### 1.
