Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 0.1.4 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The automatic postinstall performs package-owned OpenCode extension setup in the consumer workspace, creating lifecycle-related control-surface risk. The inspected source shows ownership and conflict safeguards but no concrete malicious behavior, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-12T16:23:23.367Z - **Finished:** 2026-10-12T16:25:17.892Z - **Download time:** 1006 ms - **Static scan time:** 94 ms - **AI review time:** 113424 ms - **Total time:** 114525 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The postinstall hook automatically adds this package's agent and command files to the consuming workspace's OpenCode directories. This is first-party extension setup, but it can modify workspace controls as a side effect of dependency installation. - **Trigger:** Installing the package with lifecycle scripts enabled triggers postinstall. - **Impact:** OpenCode behavior and workspace contents can change without a separate installer command; existing unowned files and an existing main configuration file are preserved. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T16:25:17.892Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer selects the consuming workspace by default and copies package-owned agents, commands, tools, and system files into it. - **Rationale:** The automatic postinstall performs package-owned OpenCode extension setup in the consumer workspace, creating lifecycle-related control-surface risk. The inspected source shows ownership and conflict safeguards but no concrete malicious behavior, so this warrants a warning rather than a block. - **Files touched:** .opencode/agents, .opencode/commands, .opencode/opencode.json, tools/, tera-system/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs scripts/install.js from its postinstall hook., The installer defaults its target to npm's INIT\_CWD, so it can write into the consuming workspace during installation., The installer copies this package's agents and commands into the workspace's .opencode directories and also installs its tools and system files., The installer preserves differing unowned files and keeps an existing .opencode/opencode.json unchanged., The build helper invokes npm pack to create a release artifact; that behavior is separate from the postinstall hook. - **Evidence against:** The installer limits its agent and command additions to this package's own files and preserves unowned files. The inspected source does not establish credential transfer or remote payload execution. ## Affected versions and remediation This report applies to @tera-system/core@0.1.4. - Review the evidence and your use of @tera-system/core@0.1.4 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
